Crazy Science Games

Crazy Science Games covers individual skills within 46 short KS3 and GCSE science games. Every game is free, without a login, adverts or tracking cookies.

Balance It asks you to count atoms on both sides and choose the balanced symbol equation. It includes state symbols, such as (aq) for a substance dissolved in water. Use it when pupils know the formulae but lose track of atom numbers. Before answering, make a small tally for each element on each side. Afterwards, ask pupils to explain which number they changed and why the formula itself stayed the same.

Periodic Table Challenge covers placing elements by group and period, electron arrangements and relative formula mass. You find formula mass by adding the masses of the atoms in a formula. The game uses your exam board's periodic table. Keep an atom count beside each mass calculation so you can spot a missed subscript. Choose this game when pupils need practice using the table to answer questions.

Group Trends asks you to place elements in groups 1, 7 and 0, order trends and predict halogen displacement. Displacement happens when one element replaces another in a compound. Pick it after teaching the group patterns. Ask pupils to write a prediction before they answer, then name the trend behind it. In discussion, compare two predictions and ask what changes when you move down the group.

Reactivity Rank uses your exam board's metal list and asks whether one metal can replace another in a compound. It suits pupils who recall individual metals but cannot use their order to predict a reaction. Sketch the relevant part of the list before answering. After playing, give a pair of metals on paper and ask pupils to justify their prediction using their positions in the series.

pH Detective sorts acidic and alkaline samples, asks which salt an acid makes and distinguishes strong acids from concentrated ones. These are separate ideas, so choose the task that matches the confusion in pupils' work. For a starter, ask each pupil to write what they mean by strong and concentrated before playing. Return to those answers afterwards and correct them with an explanation from the lesson.

A no-timer round of ten leaves room to check each answer; you can also select a harder start or class teams mode. For lessons, read the teacher page and match the topic through the exam board map. Every game has a score and streak; select Class teams mode on its start screen.

Choose this if you can name a chemistry skill you need to practise, such as counting atoms or predicting displacement.

PhET Interactive Simulations

PhET's science simulations are free for pupils and teachers, online or as downloads. The University of Colorado Boulder produces them and provides teacher activities. Using a simulation needs no pupil account. PhET has no advertising or marketing tracking cookies.

Choose a model over our games to investigate a change. Predict a model's result, then explain what happens. PhET's separate Studio tool uses paid licensing.

Choose this if you want pupils to investigate a chemistry idea through a model they can change.

Wordwall

Wordwall's templates include quizzes and matching activities, with interactive and printable formats. Its free Basic plan permits three activities and includes 12 templates. Pupil accounts are unnecessary for playing activities.

Match acids to their salts using examples from your lesson. GCSE chemistry filters exist in the community library, though free searching is limited. Check borrowed questions against the reactions you have taught.

Choose this if a short teacher-made activity can target your class's confusion about chemical names.

Wayground

Wayground lets teachers deliver assessments live or at the pupil's pace. Basic is free and includes assessments, flashcards and presentations, with limits on question types. Pupils can join games without an account, and personalised adverts are excluded by its privacy policy.

A teacher could write alternative equations and ask pupils to identify which conserves every atom. Check shared science resources carefully because the library is mostly oriented towards US courses.

Choose this if your chemistry quiz needs particular equations.

For full-course revision

Use BBC Bitesize or Seneca Learning when you need to learn the whole chemistry course. Both cover more ground than these short rounds. Choose BBC Bitesize for free study support or Seneca for chemistry courses and practice questions matched through its exam-board selector. Seneca's free access has limits; teachers can set automatically marked homework without paying.

Choose Educake if your department wants paid KS3 and GCSE science access, costing GBP 880 a year plus VAT with separate Student logins.

Choose Carousel if you want to revisit reaction facts through recall quizzes; its free Silver plan allows four quizzes a week.

Start a chemistry lesson with an atom count

Write an unbalanced equation from a reaction the class has already met. Ask pupils to count each element on both sides before choosing coefficients, the numbers in front of formulae. Compare the counts in pairs and keep the original attempts. This gives you a reason to choose Balance It: pupils can practise the step that their written answer shows they need.

Let pupils use a no-timer round of ten and record one equation they found difficult. Ask them to explain their atom counts to a partner. A harder start suits pupils who can already justify their choices. For Class teams mode, require a written tally before the team answers so everyone has a chemistry task to discuss.

End with a different equation on paper. Ask pupils to add state symbols only where they know the states of the substances. Compare this attempt with the first one and discuss any count that still differs between the two sides. If the formulae themselves are unfamiliar, teach that part before assigning more balancing practice.

Which games help pupils balance GCSE chemistry equations?

Balance It focuses on counting atoms and choosing a balanced symbol equation, with state symbols included. Use it after pupils know the formulae of the substances involved. For a teacher-written set using reactions from your lesson, Wordwall or Wayground gives you control over the examples. Follow play with an equation pupils balance on paper.

What is best for periodic table revision at GCSE?

Periodic Table Challenge practises placing elements by group and period, electron arrangements and formula mass. Group Trends focuses on groups 1, 7 and 0 with reaction predictions. If you need to relearn the topic before playing, use BBC Bitesize or a Seneca chemistry course. Check the course your school follows when choosing revision content.

Should chemistry revision use games or course content?

Use both for different jobs. BBC Bitesize and Seneca cover course content more broadly than our games, which practise selected skills. Start with an explanation when a reaction makes little sense, then test a specific skill. Teachers can add Carousel quizzes to revisit earlier facts and use a relevant PhET model when pupils need to investigate an idea.
