Different Gases

In Air Has Weight, weigh an empty PET bottle against one pumped full of air — the number on the scale proves that invisible air really does weigh something. In Bigger, Smaller, heat a balloon and watch it swell, press it and watch it shrink, then move the scene deep underwater or up a mountain to see pressure change its volume too. In Which Gas Is It?, run tests on oxygen, carbon dioxide, nitrogen, and helium one by one to tell them apart and learn what each is used for. Invisible doesn't mean nonexistent — weight and volume make air's behavior visible.
About this app
Different Gases is an interactive elementary science app about the properties of air and common gases. Explore how pumping air into a bottle changes its weight, how temperature and pressure affect gas volume, and how simple experiments distinguish oxygen, carbon dioxide, nitrogen, and helium. Mission-based activities guide learners through each concept with adjustable controls and visual demonstrations.
Use cases
- Elementary students learning about matter and gases
- Teachers introducing air weight, pressure, and volume
- Parents guiding hands-on science exploration at home
- Learners reviewing oxygen, carbon dioxide, nitrogen, and helium
Features
- Compare empty and air-filled bottles using a simulated scale
- Adjust pumping and balloon counts to observe changes in weight and balance
- Explore gas volume under temperature, squeezing, underwater depth, and altitude scenarios
- Run identification experiments for oxygen, carbon dioxide, nitrogen, and helium
- Complete four missions in each of three learning tabs
