In this activity, learners explore sensors and focus specifically on how to measure humidity using a sensor.

In this activity about transfer of energy, learners get to build their own catapult using nothing more than a plastic spoon and some tape.

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, learners design a bungee jump for an egg using nylon stockings.

In this activity, learners make an equatorial sundial, which is simple to construct and teaches fundamental astronomical concepts. Learners use the provided template and a straw to build the sundial.

In this activity on page 7 of the PDF, learners investigate the solubility of gas in water at different temperatures. This experiment will help learners determine if temperature affects solubility.

In this hands-on activity, learners determine the types of chemical reactions achieved when combining different household products.

In this activity (on page 12 of the PDF), learners make a sundial (shadow clock) appropriate for their geographic location in the northern hemisphere and use it to tell time.

Learners add two dyes to mineral oil and water, and then compare their miscibility (how well they mix) in each.

In this activity, learners explore how anemometers work to record wind speeds and how the equipment has undergone engineering adaptations over time.

In this chemistry activity, learners witness an exothermic reaction, while making their very own, completely usable sidewalk chalk. This is also an excellent activity for exploring color mixing.

In this laboratory activity, learners design an experiment to evaluate how environmental factors influence the growth of molds.

In this physical sciences activity, learners use science to solve a "crime." Learners collect trace evidence (glitter) and explore its characteristics, such as color, size, shape, and light reflection

In this activity, learners will observe a deceptively simple process: a burning candle.

In this activity, learners test the pH of safe liquids available at home by creating a pH indicator from mashed blueberries.

In this chemistry investigation, learners combine common cooking substances (flour, baking powder, sugar, salt, pepper, oil, water, food coloring) to explore mixtures.

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

In this activity that can be used as a lab or demonstration, learners use Lactaid® and lactose to demonstrate the concept of enzyme action.

Learners attach an egg to a rubber-band bungee cord and drop the egg.

In this activity, learners discover the principles of edible glass by making a supersaturated sugar solution.
