This activity (page 2 of the PDF under SciGirls Activity: California Fish) is a full inquiry investigation into environmental adaptation.

Learners draw and describe a leaf, and then re-find leaves drawn and described by other learners. Learners can observe leaves outside, or leaves may be brought into the classroom.

In this activity, learners build an instrument for catching and observing flies. Learners act as entomologists, attract flies into a jar using a slice of apple, and then observe the flies' behavior.

In this activity, learners perform a plant dissection to gain a better understanding of a plant’s structure and function.

In this outdoor activity, learners find the swollen bumps known as "galls" on various plants and get a closeup look at the parasitic animals living inside.

In this physical sciences activity, learners explore how forensic investigators collect prints from a crime scene. Learners make hand impressions in damp sand and analyze the patterns they observe.

In this activity, learners explore the question "What is paper?" Learners discover the processes and materials required to make paper while experimenting with different recycled fibers and tools.

Learners use a transparent plastic glove as a container to grow seeds. A different kind of seed can be planted in each finger.

In this activity, learners investigate how wolves communicate with each other through different body postures.

This is a demonstration about how nature inspires nanotechnology. It is easily adapted into a hands-on activity for an individual or groups.

In this activity, learners interact with whale artifacts such as replicas of skulls, bones, teeth, and baleen (hair-like plates that form a feeding filter).

This activity (on pages 24-29) combines science and art to introduce learners to how different animal pollinators spread pollen from one plant to another, and how certain shapes, colors, and smells of

In this hands-on activity, learners discover the similarities and differences between a vertebrate and invertebrate by dissecting a perch and a crawfish.

This activity (on pages 19-25) is about fleas and ticks, which are common pet parasites.

Learners construct a bracelet containing two strands of beads, which represents a double strand of DNA that codes for a gene. They match beads to the bases in a section of a chimp's DNA code.

Learners roll their fingerpads in ink pads, and then press their fingerprints onto balloons. Learners inflate the balloons to produce enlarged versions of their fingerprints.

This activity includes several games about animal sounds. Using their sense of hearing and communicating with various kinds of noisemakers, learners role-play predator and prey.

In this experiment, learners examine the way oil affects bird feathers and test different cleanup methods to find out which works best.

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.

In this quick activity (page 1 of the PDF under SciGirls Activity: California Fish), learners will build a simple Cartesian Diver in an empty 2-liter bottle.
