In this activity, a lightbulb is placed in front of a concave mirror. The actual lightbulb is not visible to the viewer, but the viewer can see the mirror image of the lightbulb formed in space.

This activity (on page 2 of the PDF under SciGirls Activity: Extreme Sounds) is a full inquiry investigation into sound.

In this activity, learners conduct tests for proteins, glucose, and starch.

In this fun optics activity, learners explore principles of light, reflection (mirrors), and perception. Learners work in pairs and sit on opposite sides of a "two-way" mirror.

In this activity about light and reflection, learners discover that what you see is often affected by what you expect to see.

In this activity, learners test to see if carbon dioxide is present in the air we breathe in and out by using a detector made from red cabbage.

In this biology activity, learners use plastic pipettes to cut wells into the solid gel layer of agar in petri dishes and place solutions of simulated antigen and antibody preparations into the wells.

In this set of outdoor games, learners play the role of monkeys that are trying to get enough resources (food, shelter, and space) to survive.

In this activity on page 5 of the PDF, learners compare water with artificial urine to see how urinalysis works. Learners use urinalysis test strips to test for glucose and protein in the fake urine.

This simulation of laparoscopic surgery enables learners to practice and to learn this modern surgical technique.

In this activity, learners use molecular model kits to construct familiar molecules like lactose, caffeine, and Aspirin.

In this activity, learners explore the concept of valve operation and how engineers have adapted valves for use in mechanical heart valve design.

This activity (on page 2 of the PDF under SciGirls Activity: Forensics) is a full inquiry investigation into how hairs from a crime scene are matched to suspects.

In this activity, learners use household materials to investigate and explore their ability to smell an odor.

In this highly physical outdoor activity, learners construct and compare experimental trail sections to select the best trail-construction technique for their site.

In this activity about heart health (on page 34 of the PDF), learners measure their own blood pressure using an electronic blood pressure monitor with a self-inflating cuff (included in cost of materi

In this activity that can be used as a lab or demonstration, learners use Lactaid® and lactose to demonstrate the concept of enzyme action.

In this activity (page 10), learners explore how molecules self-assemble according to forces of attraction and repulsion.

In this activity, learners design a therapeutic agent to image and/or cure various diseases in the respiratory system.

In this open-ended multicultural lab activity, learners investigate the effectiveness of herbal remedies.
