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 simulation, learners explore how ocean currents spread all kinds of pollution—including oil spills, sewage, pesticides and factory waste—far beyond where the pollution originates.

In this activity, learners explore trebuchet design. Teams of learners construct trebuchets from everyday materials.

In this design challenge activity, learners build a shock-absorbing system that will protect two “astronauts” when they land.

In this hands-on experiment, kids use chemistry to explore whether acids or bases are better at restoring a penny’s shine.

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

In this activity, learners use chocolate to explore how the Sun transfers heat to the Earth through radiation.

This is a highly visual demonstration that illustrates both the effects of density and chemical reactions.

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

In this activity about combustion and energy, learners observe a burning candle in a sealed jar and the burning of white sugar.

This is a fun activity about the power of the Sun and the importance of using sunscreen to protect your sensitive skin from its rays.

In this activity, learners use detergent solution to compare two solutions containing vinegar and cream of tartar.

In this activity, learners review the history of gumball machines and explore potential and kinetic energy, while working in teams to build a gumball slide.

Learners observe and conduct experiments demonstrating the different properties of hot and cold materials.

In this activity, learners explore what happens when polarized white light passes through a sugar solution.

In this activity, learners build models of atoms and molecules, then consider their role in different phases of matter, density, and mixtures and solutions.

This activity uses Jell-O(R) to introduce learners to microfluidics, the flow of fluids through microscopic channels.

In this activity, learners explore how packaging engineers develop customized shipping and packaging containers to meet the needs of many different industries.

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

Can gelatin (like Jell-O ®) change the speed of light?
