ExploreLearning Gizmos for Students | Virtual Science Labs, Mathematics and Evidence
ExploreLearning Gizmos lets pupils change the variables in a virtual investigation and watch a mathematical or scientific relationship unfold. A child can compare fractions on a number-line garden, model a moving object, investigate measurements or test a prediction several times without needing a physical laboratory for every first attempt.
The attraction is that the learner can experiment quickly. The danger is that a simulation may appear to prove more than its settings and assumptions justify. Moving a slider until the graph looks convincing is not the same as understanding the relationship.
Parents searching for ExploreLearning Gizmos for students, Gizmos free trial, Gizmos login, Gizmos classroom code, or free Science virtual labs need an accurate picture of the service’s changing free-access arrangements, classroom controls and value for Singapore school study.
Quick answer: ExploreLearning Gizmos offers a library of 550-plus interactive Mathematics and Science simulations, mainly for US grades 3–12. Its current free trial provides 30 days of broad access, after which a free account keeps a smaller rotating set of simulations. Students usually join a teacher’s class through a code and authorised school account. Effective practice follows predict → identify variables → run a controlled test → collect values → explain the result → test a fresh case independently.
What Are ExploreLearning Gizmos?
A Gizmo is a digital interactive model designed to support mathematical or scientific investigation. Some Gizmos include adjustable numbers and diagrams; others use animations, graphs or virtual equipment.
The official product page describes a substantial range of Mathematics and Science topics, inquiry-led tasks and supporting lesson resources.
A pupil can change one quantity and observe what happens to another. This can help when a relationship is difficult to understand from a static image.
For example, a fraction model can show how three quarters compares with six eighths. A motion model may help reveal a change in distance over time.
However, a model is built according to rules selected by its designers. Students need to recognise which details are represented and which aspects of a real system have been simplified.
The greatest value is not seeing something move, but correctly explaining why the model behaved as it did.
Is Gizmos Free in 2026?
The official free trial offer advertises 30 days of access to the full library, after registration through the appropriate educator route.
The registration form asks the registrant to confirm they are at least eighteen. A child should not enter a false age to create an educator account.
After the trial, the account can continue with a limited rotating selection of free Gizmos. The remaining catalogue generally requires the appropriate school or institutional subscription.
This differs from PhET Simulations for Students, which has a different access and licensing arrangement.
Parents should check whether the school already provides Gizmos before paying or setting up a duplicate account.
A paid licence can support teaching, but the learning value still comes from the chosen investigation and feedback.
What Happens After the 30-Day Trial?
ExploreLearning’s current account guidance describes a thirty-day trial and a later limited free account.
The free catalogue is a rotating selection from the larger library. The company’s free-account change guide warns that previous free selections can revert to a short daily preview limit when the list changes.
Students may also lose normal class access to previously available free simulations, even while teachers retain certain prior assessment records.
This matters for planning a unit that lasts several weeks. A teacher should not promise that a particular free simulation will remain fully available for the entire year.
When the class plans a project, confirm that the selected Gizmo is available for the relevant dates or that the school has an appropriate licence.
A useful printed record of predictions, measurements and conclusions can preserve learning even when software access changes.
What Does the Free Trial Include?
The official trial page currently advertises access to the 550-plus Gizmo library, on-demand training resources and exploration of additional products.
There is an important limit: ordinary trial accounts do not automatically include teacher answer keys. The provider directs educators to seek permission or further assistance when answer-key access is needed.
Students should not assume that a complete answer sheet is necessary to learn through a virtual experiment.
A good investigation has the learner predict and explain what happens. Teacher guidance can then determine whether the explanation is valid.
For a school reviewing the product, a trial can help identify useful topics and check the device environment.
Do not confuse a general product demonstration with an automatically authorised class subscription.
How Do Students Sign In?
The current login instructions direct users to the official Gizmos service and its Login/Enroll route.
A student normally receives account or class-access instructions from an educator. When schools use class codes, pupils can enrol through the appropriate class joining workflow.
The official class-code instructions describe students using an authorised class code, creating an account as directed and joining the specific teacher’s group.
Do not share another child’s username or password to access a simulation more quickly.
Where the school already manages an account, follow its exact link rather than making an unrelated personal profile that the teacher cannot monitor.
Access is a classroom administration step; understanding the Science or Mathematics remains a separate task.
What Are Gizmos Class Codes?
A class code identifies a teacher’s specific Gizmos class. The official help says teachers can locate codes from their class-management area.
Students can use the code to enrol in the correct class under the provider’s supported workflow.
A student who has already joined another class can follow the service’s existing-account guide to join an additional class where authorised.
A classroom code is not a general public voucher for the complete simulation library. Licence and class permissions still determine what the learner can use.
Before a child joins, confirm the teacher’s name and class information.
Avoid posting class codes together with pupil credentials in unrestricted public groups.
The correct class should be used for tracking school work and feedback.
The Scientific Method Starts Before the Slider Moves
Interactive software makes experimentation look easy. But investigation requires deciding what question is being asked and how to test it.
Begin with a prediction based on an explicit principle. Identify the independent variable, or quantity deliberately changed, and the dependent variable, or quantity observed or measured.
Ask which other conditions need to be controlled or kept comparable.
Then run the test and record what actually happened, including units and relevant settings.
If the result differs from the prediction, identify whether the concept, model or experimental setup needs revision.
A child who changes several sliders simultaneously may create an interesting effect while losing the ability to explain which change caused it.
Controlled comparison is more important than visual excitement.
Worked Example 1: Equivalent Fractions in a Garden
The current free Gizmos catalogue has featured a Fraction Garden activity for comparing fractions.
Imagine a teacher asks whether 3/4 and 6/8 represent the same part of an equally sized whole.
Three quarters is equivalent to six eighths because multiplying both numerator and denominator by two preserves the fraction’s value.
In the model, placing the values on comparable 0-to-1 number lines should produce the same position.
The learner should explain why the numerators differ despite the equal numerical values.
Now compare 3/4 and 3/8. These are not equal; three eighths is smaller for the same-sized whole.
Close the simulation and ask whether 2/3 equals 4/6. The pupil should justify the equivalence symbolically or with a paper model.
The purpose is fraction sense, not knowing where a particular on-screen flower belongs.
Worked Example 2: Fractions and Difference
Suppose a student compares 5/6 with 3/4.
Use a common denominator: 5/6 = 10/12 and 3/4 = 9/12.
Therefore 5/6 is greater by 1/12.
A visual number line can show how close these fractions are, but the child should calculate the difference accurately.
Ask what would happen if the fractions were compared only by their numerators. The larger numerator happens to accompany the larger value here, but that is not a reliable general rule.
For a counterexample, compare 3/4 and 4/9. Although four is a larger numerator than three, 3/4 is greater.
The pupil should explain that denominators specify the size of equal parts.
A new unaided comparison provides more evidence of understanding than the simulator’s correct display.
Worked Example 3: Area and Perimeter
Consider a simulated grid containing a rectangle 8 units long and 5 units wide.
Its area is 8 × 5 = 40 square units. Its perimeter is 2(8 + 5) = 26 linear units.
Change the rectangle to 10 by 4. The area remains 40 square units but the perimeter changes to 28 units.
This is a powerful relationship to explore because students sometimes treat area and perimeter as interchangeable.
Ask which measure describes the inside and which measures the boundary.
The exact Gizmo used should support the required mathematical representation; do not assume every geometry simulation offers the same measurement controls.
After the demonstration, give the pupil a 9-by-3 rectangle on paper. They should calculate 27 square units and 24 linear units unaided.
A useful virtual lab ends with a correct independent method.
Worked Example 4: A Simple Motion Investigation
Imagine a virtual cart travelling at a constant speed of 2 metres per second under the stated simplified model.
After three seconds, it has travelled 6 metres. After seven seconds, its distance is 14 metres, provided the speed and start condition stay the same.
The relationship is distance = speed × time.
A learner can predict values before running the simulation and compare the results with the visual movement or graph.
Now change the speed to 3 metres per second while keeping the seven-second duration. The predicted distance becomes 21 metres.
The model can show how a constant rate changes the distance–time relationship. But real vehicles may accelerate, slow down or encounter friction and other conditions.
The pupil should distinguish the simple constant-speed model from more complex real motion.
The skill is expressing and testing a relationship with units.
Worked Example 5: Average Speed Is Not Every Instant’s Speed
Suppose a modelled object covers 120 metres in 20 seconds.
Its average speed for that trip is 120 ÷ 20 = 6 m/s.
That does not establish that it travelled exactly 6 m/s throughout the journey. It may have sped up and slowed down.
If a simulation shows a changing velocity curve, the learner should recognise that instantaneous and average quantities answer different questions.
Ask what additional information would be needed to describe the motion at a particular moment.
Now consider a second journey of 90 metres in 15 seconds. Its average speed is also 6 m/s.
Equal averages do not necessarily mean identical movement patterns.
This is an example of mathematical precision needed when interpreting a simulation’s results.
Worked Example 6: Designing a Fair Test
Imagine a virtual investigation of seedling growth under different light exposures.
The teacher asks which factor was deliberately changed. If the test varies light while other intended conditions remain comparable, light exposure is the independent variable.
The measured quantity might be plant height after a specified period or change in height, depending on the experiment’s actual design.
The child should identify possible controls such as type of plant, watering, soil conditions and measurement period.
A wrong conclusion would be: One simulated plant grew taller, so the highest light level is best for every plant in the world.
The data cannot justify that universal claim.
A useful retest changes a different variable—such as water supplied—under a newly defined fair comparison.
The child must explain the new independent variable and measured outcome.
Worked Example 7: Density and Floating
Density is mass divided by volume.
For a hypothetical material with mass 120 g and volume 40 cm³, density = 120 ÷ 40 = 3 g/cm³.
If another sample has the same material density but twice the volume, its mass would be 240 g under the same model.
This is a mathematical relationship, not a prediction that every object with a certain shape will float or sink.
Floating depends on a comparison with the fluid and the displaced volume, among other circumstances, and a hollow object may have an average density different from the material making its walls.
Use a relevant simulation to explore a controlled density problem where the tool supports it.
Then ask for a paper calculation with a new mass and volume.
A strong learner can distinguish formula, measured values and physical interpretation.
Worked Example 8: Energy and Power
Suppose an electrical device is modelled as operating at a constant power of 100 watts for two hours.
Its energy consumption is 100 W × 2 h = 200 watt-hours, or 0.2 kilowatt-hours.
A second device operating at 50 W for four hours also consumes 200 Wh.
A simulation can help students compare rates and totals, but it should not lead them to confuse power with accumulated energy.
Ask what changes if the duration doubles while the power stays constant.
The energy consumed doubles. This is a direct consequence of multiplying rate by time.
A real appliance may have variable power draw, so the example is based on a deliberately simplified assumption.
The learner should be able to state that condition when interpreting a virtual result.
Gizmos for Algebra and Functions
Interactive Mathematics models can help students connect an equation, a table and a graph.
Consider y = 2x + 1. When x = 0, y = 1; when x = 2, y = 5; when x = 4, y = 9.
These values lie on a straight line with gradient 2 and y-intercept 1.
A suitable Gizmo or graph model might help the pupil see how changing a coefficient affects the slope.
But a graph does not replace the symbolic reason. The coefficient 2 means y increases by two when x increases by one unit under this equation.
Ask the child to predict values for x = 5 and x = −1 before consulting the software.
Then transfer the learning to a fresh equation such as y = 3x − 2.
The aim is connected representations, not visual memorisation.
Student Exploration Sheets and Predictions
ExploreLearning provides lesson materials such as Student Exploration Sheets under relevant access arrangements.
The official lesson-materials support hub includes guides for teachers and student exploration.
These worksheets can help learners record predictions, define variables, run trials and interpret the findings.
A useful sheet asks for an explanation before the simulation reveals the outcome.
If a student fills all responses by copying a teacher’s completed answer key, the sheet becomes a transcription task rather than scientific inquiry.
A teacher can require a first attempt, followed by group discussion and an individually written correction.
The most revealing part of a good investigation is often where the learner’s expectation diverged from the observed model.
Document that difference clearly rather than erasing the original prediction.
Assessment Questions and Real Mastery
Some Gizmos include accompanying assessment questions or reporting under supported subscriptions.
These can help identify whether students remember terminology or can interpret the represented relationship.
However, multiple-choice accuracy cannot always explain why an answer was selected. A student may have guessed correctly or used an incomplete shortcut.
Ask the learner to provide one sentence justifying the chosen response, then solve a changed problem without answer choices.
If a class report reveals a repeated misconception, pause for a concept explanation rather than assigning another large batch immediately.
The correct follow-up is determined by the nature of the error.
A virtual lab’s grade or completion state is not an official Singapore examination mark.
Learning remains a process of understanding, applying and verifying.
STEM Cases and Real-World Roles
ExploreLearning also advertises STEM Cases in which learners address a scenario through an applied science or engineering role.
Such activities can make inquiry feel purposeful. A pupil might need to evaluate evidence, compare measurements and make a recommendation.
But the simulated scenario may simplify the real professional task. The student should know what data were available and what assumptions the case made.
A valid conclusion should follow from the evidence rather than from whichever response advances the game.
Ask the class to write a short decision memo: the selected action, two supporting observations and one important limitation.
This connects interactive Science with communication and real-world decision-making.
It also teaches that uncertainty is normal when evidence is incomplete.
Gizmos and Physical Laboratories
A virtual environment is useful for visualising relationships and repeating a simplified experiment, particularly when equipment is expensive or classroom time is limited.
It cannot fully reproduce real measurement uncertainty, instrument handling, unexpected component faults or every safety requirement.
Students should therefore distinguish virtual observation from physical measurement.
For example, a simulated pendulum might behave under ideal conditions, while a real pendulum also involves air resistance and imperfections in its support.
A virtual Chemistry result does not automatically authorise repeating that experiment with unknown substances at home.
Where a physical practical is required, follow the school’s approved equipment and supervision.
The best learning programme uses simulations and hands-on work for different, complementary purposes.
Singapore Primary Science and Mathematics
Some Gizmos topics overlap with Singapore Primary concepts such as fractions, measurement, forces, heat and simple investigation methods.
However, the platform’s US grade and standards labels are not direct conversions to MOE Primary school levels.
Use the teacher’s actual current topic to select the investigation. A Primary 5 pupil may need a clearer explanation of a fair test more than an advanced graph.
For Mathematics, supplement the simulation with appropriate written solutions and Singapore word-problem methods.
A virtual result should lead to an independent calculation or explanation that resembles the demands of schoolwork.
For broader foundations, see How Primary Science Works.
The learning target remains the subject concept, not the number of simulations completed.
Secondary G1, G2 and G3 Applications
Secondary students may use selected Gizmos to investigate more complex relationships in Chemistry, Physics, Biology and Mathematics.
The appropriate depth depends on the subject level and syllabus. A Secondary 1 learner should not be forced through an advanced task simply because a simulated graph looks impressive.
For a learner studying algebra, work with equations and changing quantities. For Science, ask for controlled variables, actual units and limitations.
An older pupil can also discuss what the simulation assumes about the real system and whether the model’s predictions could be tested physically.
Do not claim that finishing a US Grade 8 Gizmo proves mastery of the Singapore SEC syllabus.
A good teacher uses the tool to reinforce concepts at the correct level, then checks unfamiliar written tasks.
The student’s independent reasoning remains the essential outcome.
Gizmos Versus PhET and CK-12
PhET Simulations for Students offers another route to interactive exploration.
CK-12 for Students combines digital textbooks, practice and simulations within its learning environment.
Gizmos places emphasis on inquiry activities, an extensive simulation catalogue and teacher-facing materials.
These are different teaching workflows, not a simple ranking. For a brief home demonstration, a freely accessible simulation may be sufficient. For a class with a funded licence and structured investigation materials, Gizmos may suit the teacher’s needs.
Avoid shifting pupils among several simulators without a clear learning objective.
Select the tool that makes one difficult relationship easier to predict, test and explain.
A Twenty-Five-Minute Gizmos Learning Routine
Try a focused session:
- Minutes 1–4: State the question and predict the outcome.
- Minutes 5–8: Identify variables, controls and relevant units.
- Minutes 9–14: Run two or three appropriately controlled trials and record observations.
- Minutes 15–18: Explain how changing the input affected the measured outcome.
- Minutes 19–21: Check the result against a suitable physical or mathematical principle.
- Minutes 22–25: Close the simulation and complete a changed question independently.
A teacher may need much longer for a full inquiry or complex STEM Case. This is only a starter structure.
For a three-student tutorial, rotate investigator, calculation checker and explanation writer roles.
If the final independent question fails, revisit the first misconceived relationship rather than running more random trials.
The experiment is successful when it improves the next unaided decision.
Classroom Privacy and Safe Participation
Students should join through the authorised class code and use school-approved usernames.
Do not circulate account passwords, individually identifiable results or confidential class materials in public forums.
Educator trial registration has its own adult eligibility requirements. Pupils should not pretend to be teachers to obtain the thirty-day offer.
When sharing screenshots of a Gizmo, remove unrelated student information and identify the model and settings so another reader understands the evidence.
A teacher should also verify the provider’s current privacy and institutional account terms before distributing new access.
Scientific curiosity does not require exposing a child’s identity.
Safe access helps the student concentrate on the actual investigation.
