In this activity, learners measure the amount of carbon dioxide in a carbonated drink.

In this activity, learners conduct an experiment to find the volume of one mole of gas. Learners capture sublimated gas from dry ice in a ziploc bag and use water displacement to measure its volume.

This activity was designed for blind learners, but all types of learners can participate to learn about conservation of gas. This is one of the classic experiments using baking soda and vinegar.

In this activity, learners cut wells in JELL-O© and load the wells with different detergent solutions.

In this activity, learners observe the effect of transpiration as water is moved from the ground to the atmosphere.

In this experiment, learners will conduct chemical and physical tests to identify mystery substances.

Learners smell balloons filled with different scents to guess what's inside. From this, they infer the presence and motion of scented molecules.

In this activity, learners observe how salinity affects the freezing point of water by making and enjoying ice cream.

In this activity, learners estimate how much water they think can be found in various locations on the Earth in all its states (solid, liquid, and gas) to discover the different water ratios in the Ea

In this activity, learners discuss the different salinities of oceans, rivers and estuaries.
