In this activity (Page 30 of PDF), learners investigate the evolution of wheat by conducting sedimentation tests on different flours.

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

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.

In this activity, learners make their own bug boxes and test the habitat preference of selected "minibeasts" (bugs).

In this health activity, learners explore breathing, lungs and asthma. Learners test their lung capacity by blowing air into balloons.

In this activity, learners explore the structure of plant leaves. Learners find out what happens when they coat either the top or bottom sides of leaves with petroleum jelly.

In this activity (page 7 of the PDF), learners will investigate the contents of owl pellets. Learners will discover how owls digest their food as well as the kind of animals they eat.

In this three-part activity, learners conduct simple experiments to see how light refracts and reflects, and how colors of light affect what we see.

In this activity, learners investigate how plants use water. By making the flowers change color, learners see how water moves up the stem to the leaves and the flowers.

In this experiment, learners work in pairs to create two gloves -- one that contains a layer of shortening (blubber) inside, and one that doesn't.

In this activity, learners determine the necessary conditions for pea seed germination.

In this health activity (page 5 of the PDF), learners will explore a unique connection betweeen the bones of the body.

This activity (on page 3 of the PDF under GPS: Body Electricity Activity) is a full inquiry investigation into conductivity.

In this lab, learners evaluate the relative effectiveness of various chemical substances (i.e. garlic powder, bathroom cleaner, mouthwash, etc.) as antimicrobial agents.

In this activity, learners observe how salinity affects the freezing point of water by making and enjoying ice cream.

Learners observe different light sources, outdoors and indoors, using prism glasses (diffraction glasses) and color filters.

In this activity, learners compare ways to measure their heart rates. Learners build their own stethoscopes and learn how exercise affects heart rate.

In this simple chemistry activity (page 1 of PDF under SciGirls Activity: Colorblind Dogs) about acids and bases, learners will mix a baking soda and water solution and use it to paint a message on a
