Learners explore capillary action in plants (such as plants ability to move water from roots to leaves) in an investigation called Paper Blooms.

This lesson focuses on graphene and its electrical properties and applications.

In this environmental health activity, learners grow and observe bread mold and other kinds of common fungi over the course of 3-7 days.

In this activity, learners use water, oil, and food coloring to observe a chemical reaction that creates a shower of colors inside of a glass.

In this activity, learners will build a stomp-powered launcher to blast off paper rockets they design. Materials can be found at a local hardware store or you may already have them at home.

Learners explore water adhesion and learn about why water molecules are more strongly attracted to some substances than others.

In this activity, learners design and build a simple wind vane —one of the oldest kinds of weather tools— and use it to show wind direction.

In this nutrition activity (page 16 of PDF), learners document their individual eating habits and learn whether their eating patterns meet their needs.

In ancient Chaco Canyon, the people used a "sun dagger" petroglyph to mark the passing of seasons.

In this activity about sleep rhythms (on page 25 of the PDF), learners will investigate how changing the time they go to bed impacts their own sleep patterns.

In this activity, learners will discover how fossils are dug out of the earth by carefully exposing treasures hidden in an artificial rock that is easily made at home.

In this activity, learners will investigate the sounds of the heart.

In this plant science activity, learners role play as vegetables and weeds competing for nutrients.

In this activity, learners separate a mixture of pebbles, salt crystals, and wood pieces. They add water and pour the mixture through a strainer.

In this activity, learners explore how distance can affect the way we perceive the size of an object.

In this activity related to microbes, learners use water drops and hand lenses to begin the exploration of magnification. This activity also introduces learners to the microscope.

This game depicts a woman going through her day, faced with various loud sounds.

In this chemistry activity, learners transform two ingredients (4% polyvinyl alcohol solution and 4% borax solution) into gooey slime.

In this meteorology activity, learners construct simple devices to measure the direction and speed of wind.

In this activity and/or field trip, learners investigate the water currents that aquatic animals create when they breathe, feed, and propel themselves through water.
