In this activity, learners will make their own slushies and learn some of the science behind how the process works.

In this sensory activity, young learners explore chemical reactions by making their own play dough from home.

In this activity related to rotational inertia (page 1 of the PDF under SciGirls Activity: Microgravity), learners will use a bit of scientific experimenting to test if open-faced peanut butter sandwi

In this activity, learners will explore the dynamics of air pressure by using a candle, a cup, and a dish of water.

In this activity (page 26 of the PDF), learners make observations, formulate hypotheses and design a controlled experiment, based on the reaction of carbon dioxide with calcium hydroxide.
