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.

In this art/science/math activity, young learners are introduced to the concept of symmetry in nature.

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 activity, learners are challenged to eat some candy as a cell would need to as well as to think about some of the problems that arise when a cell ingests food.

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.

In this activity, young learners go on a walk with caregivers and use their senses to observe nature with the help of scavenger hunt sheet.

In this activity, learners will explore vegetative propagation while preparing food scraps to grow into plants.

In this lesson, learners will understand the concepts behind endangered and extinct animals and develop their own conservation plan to save three endangered species.

This laboratory exercise is designed to show learners how DNA can easily be extracted from yeast using simple materials.

In this activity (p.14-15 of PDF), learners discover the concepts of competition and limiting factors as they relate to plant and animal communities.

In this activity (p.25 of PDF), learners investigate spores. Mushrooms produce millions of spores which are equivalent to the seeds of plants but without the massive food reserves.

In this outdoor activity and animal-role-play game, learners discover and uncover the hidden world of "cryptozoa"—organisms such as spiders, salamanders and slugs that live under objects, like rocks a

In this activity, learners explore dinosaur skeletons.

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 science and language arts activity, learners study fish anatomy and make their very own 3D paper fish.

In this activity, learners explore dinosaur fossils by making an edible treat. First, learners read "Dinosaur Bones" by Aliki to examine how fossils are formed.

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