Free interactive simulations and games for 7th grade science. Each one teaches a big idea by letting students experiment or play, checks understanding along the way, and ends with proof of learning. Everything is NGSS-aligned and runs in any browser with no login.
Mix real lab chemicals, use observation tools to gather evidence, and spot all 6 signs of a chemical reaction. Golden rain, pink potions, elephant toothpaste, and burning metal.
New 7th grade simulations and games are added throughout the school year.
In many middle schools, 7th grade science explores matter and how it changes: atoms and molecules, the properties of substances, and chemical reactions, often alongside topics in life and Earth science. Atoms are far too small to see, so students have to reason from evidence, like a new color, a gas, or a solid that appears out of two clear liquids. Virtual labs let every student run every reaction safely, including ones that use chemicals too toxic for most classrooms.
Simulations work like virtual labs: students follow the procedure, use observation tools to collect evidence, record what they see, and build a lab report they can screenshot and submit.
