In this activity related to plant biotechnology, learners use restriction enzymes to cut up DNA from a virus called Bacteriophage λ, a process known as restriction digestion.

This activity (on page 3 of the PDF under GPS: Cactus Activity) is a full inquiry investigation into how some desert birds keep their cool.

In this plant science activity, learners conduct four experiments to observe how plants respond to sunlight and gravity.

In this activity about sleep rhythms (on page 21 of the PDF), learners will collect data about their own sleep cycles and use a fraction wheel to examine their data.

Over the course of several days, learners explore the property of water that helps plants move water from roots to leaves or gives paper towels the capacity to soak up water.

In this math activity, learners collect, organize, and analyze a set of data related to types of animals in the temperate forest.

In this activity, learners investigate the impact of oil pollution on the environment and wildlife. Learners use hard-boiled eggs and feathers to understand the damage that oil spills can cause.

In this activity, learners create a biosphere in a baggie.

In this activity, learners build a model of a self-sustaining habitat (growing grass and beans from seeds).

In the wild, small crustaceans known as brine shrimp live in marine habitats such as saltwater lakes.

In this activity on page 8 of the PDF (Behind the Scenes with Chemistry), learners make three of Harry Potter's essential school supplies: quills, ink, and color-changing paper.

In this chemistry activity (page 8 of the PDF), learners will identify the instances of physical change, chemical change, and solutions while making homemade soda pop.

In this activity (located at the bottom of the page), learners investigate soil and explore the creatures that live in it.

In this activity, learners create a freshwater ecosystem in a large plastic bottle. Learners cut and prepare bottles, then fill with water, aquatic plants, snails and fish.

In this activity (1st on the page), learners keep a "SLOG" or Sleep Log to study their sleep patterns.

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 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 four-day activity, learners grow bacteria and/or fungi from a variety of locations and compare the results.

In this activity, learners find out what happens when they cover leaves with pieces of black construction paper. This activity shows learners that plants need sunlight to survive.

This activity features two connected hands-on activities about dinosaur bones.
