In this activity, learners use things from the kitchen as building materials to explore how shapes contribute to the strength of different structures.

In this chemistry activity, learners use the lowered freezing point of water to chill another mixture (ice cream) to the solid state.

In this introductory activity and demonstration, learners are introduced to the concept that different substances react chemically in characteristic ways.

In this activity, learners conduct a controlled experiment to examine how temperature will affect the height of a soda geyser.

In this activity related to Archimedes' Principle, learners use water displacement to compare the volume of an expanded gummy bear with a gummy bear in its original condition.

Learners carefully pour vegetable oil, water, and corn syrup in any order into a cup and discover that regardless of the order they are poured, the liquids arrange themselves in layers the same way.

In this activity, learners explore engineering package designs that meet the needs of safely shipping a product.

In this activity, learners conduct a controlled experiment to examine which brand of soda makes the best (highest) soda geyser.

In this activity, learners use chemistry to “self-assemble” gummy shapes. Learners discover that self-assembly is a process by which molecules and cells form themselves into functional structures.

In this simulation, learners use M&M™ candy to explore radioactive isotope decay.

This is an activity (on page 2 of the PDF under Surface Area Activity) about surface area to volume ratio.

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 use detergent solution to compare two solutions containing vinegar and cream of tartar.

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

In this lab exercise, learners explore diffusion, cell membranes and particle size using beets and three alcohols.

In this activity related to the human circulatory system (on page 10 of the PDF), learners observe the dispersion of a drop of food coloring in water, draw conclusions about the movement of dissolved

In this activity, learners explore deoxyribonucleic acid (DNA), a nanoscale structure that occurs in nature.

Each learner chews a piece of gum until it loses its flavor, and then leaves the gum to dry for several days.

This lesson focuses on surface area and how the shape of sugar crystals may differ as they are grown from sugars of different coarseness.

This activity (on page 3 of the PDF under GPS: Body Electricity Activity) is a full inquiry investigation into conductivity.
