In this activity, learners explore how to protect their skin while applying pesticides to plants.

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

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

In this activity, learners explore the human influences on the carbon cycle and examine how fossil fuels release carbon.

In this creative roleplay activity, learners will explore the various processes of the water cycle using movement, sound, and props to aid in comprehension.

In this online interactive simulation, learners will add different salts to water and then watch the salts dissolve and achieve a dynamic equilibrium with solid precipitate.

In this activity (pages 17-31), learners are introduced to techniques that are used to determine the structures of solid materials.

This activity explores the basic workings of a siphon, which is the core technology that makes toilets work.

In this chemistry activity, learners fill two test tubes with a solution of "artificial stomach fluid," consisting of hydrochloric acid in the same concentration as in human stomachs, some soap to cre

In this activity related to climate change, learners create and explore topographical maps as a means of studying sea level rise.

In this activity, learners use a flashlight, a glass of water, and some milk to examine why the sky is blue and sunsets are red.

In this kinesthetic activity that demonstrates pressure, learners act as air molecules in a "container" as defined by a rope.

Learners create three solutions with different levels of salinity. They compare the density of these solutions by coloring them and layering them in a clear plastic cup and in a soda bottle.

In this activity (on page 1), learners role play as atoms to explore how atoms can be rearranged to make different materials.

In this chemistry demonstration, acid rain is simulated in a petri dish.

In this activity (on page 7), learners explore the meaning of a "carbon sink." Using simple props, learners and/or an educator demonstrate how plants act as carbon sinks and how greenhouse gases cause

In this activity, learners explore the history of making objects from glass and artistry of Dale Chihuly.

In this activity about the solar system, learners use various light sources to examine ice with different components to understand how NASA studies planets and moons from space.

In this edible experiment, learners pour "Magic Shell" chocolate into a glass of cold water. They'll observe as pillow shaped structures form, which resemble lavas on the sea floor.

In this online interactive simulation, learners will test the pH of liquids like coffee, spit, and soap to determine whether each is acidic, basic, or neutral.
