This outdoor activity/field trip requires a place where minnows swim, such as a local pond or brook.

In this activity, learners rotate through several learning and play stations to explore dinosaurs and paleontologists.

Dig a hole, line it, fill it with fresh water, and you have a water hole: a good place to study colonization.

Plants need nutrients to grow. This is why we apply fertilizers to grass and food crops. In this activity, learners will explore how fertilizers can affect lakes and other bodies of water.

In this activity, learners extract DNA from wheat germ. Use this activity to introduce learners to DNA, biotechnology and genetic engineering.

In this activity, learners smell bottles containing bee pheromone molecules (or herb/spice extracts as a substitute). Bees release these molecules to send messages to each other.

In this environmental science lesson, learners will examine the dangers of mercury and how humans contribute to growing mercury emissions on Earth.

In this activity, learners collect, analyze, and interpret information about objects in order to classify them into a cladogram. Use this activity to talk about how scientists classify things.

In this experiment with planaria (a type of flatworm), learners will investigate the capability of different body sections to regenerate.

In this arts and crafts activity about animals and animal characteristics, learners will design animal hats and role-play as animals.

In this activity, learners make slides of onion cells and their own cheek cells. Use this lab to teach learners how to prepare microscope slides and use a microscope.

In this design challenge, learners will use microbes to design and grow a custom biomaterial at home and make something creative with it.

In this activity (on pages 24-34), learners explore the four-part stomach of cows (and other grazing animals called ruminants), and compare it to the human one-part stomach and its digestive process.

In this activity, learners use their imaginations and experiment with different materials to create bug hats.

In this outdoor beach activity, learners use a variety of "beaks" (such as trowels, spoons or sticks) to hunt for organisms that shore birds might eat.

In this activity, multiple learners will use a game with ballloons to learn about coqui frog behavior.

In this activity learners observe mold growth on different types of bread by measuring and recording the growth rate.

In this chemistry challenge, learners identify which plants have the enzyme "catalase" that breaks hydrogen peroxide into water and oxygen.

This activity (on page 2 of the PDF under SciGirls Activity: Pet Handedness) is a full inquiry investigation into whether pets show a preference for the left or right paw, or “handedness” like people.

This is an activity about the adaptations that allow the Aye-aye to survive in its habitat. Learners will explore how the Aye-aye collects food and how this is influenced by their specialized finger.
