How do you measure a bubble when it's floating? You can't really, but in this activity, learners can measure the diameter of the ring of suds a bubble leaves on a flat surface.

In this activity learners will measure and manipulate flubber using different tools. Learners will explore volume and make observations about texture and shapes.

This is an activity about turbidity, or the amount of sediment suspended in water.

Learners investigate signs of a chemical reaction when they mix vinegar and baking soda. In addition to a gas being produced, learners also notice the temperature decreases.

In this experiment, learners use JOY liquid detergent and glycerin to make the largest bubble they can that lasts 15 seconds.

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

In this meteorology activity, learners construct simple devices to measure the direction and speed of wind.

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
