In this math activity, learners use a variety of sensory modalities to gain experiences with identifying, describing and creating repeating patterns.

In this activity, learners investigate various appliances and electronics, discovering how much energy each uses and how much carbon dioxide (CO2) is released to produce that energy.

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

This activity (on page 2 of the PDF under SciGirls Activity: Malformed Frogs) is a full inquiry investigation into using indicator species to assess the health of an environment.

In this activity, learners stain fabrics--on purpose!

In this activity (posted on April 18, 2011), learners follow the steps to construct a zoetrope, a device that produces an illusion of action from a rapid succession of static pictures, using a 16" bik

In this activity, learners participate in a simulated dig to discover fossilized dinosaur bones. Learners take notes, make a map and propose theories about dinosaurs.

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 explore dinosaurs and fossils by creating a diorama.

In this activity, learners observe and describe the physical and behavioral characteristics of insects, including crickets.

In this activity, learners explore the factors that tend to resist changes in pH of the ocean and why the ocean is becoming more acidic.

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 ecology activity, learners make a model water-based ecosystem called a terraqua column. The column (in a large soda bottle) includes pond water, duckweed, sand or gravel, and small snails.

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, learners explore how environmental engineers might approach solving the problem of an oil spill.

In this activity, learners construct a model of DNA to better understand the structure of DNA and protein synthesis.

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

In this outdoor, beach activity, learners use tennis balls, water balloons and other simple devices to investigate the movement of waves and currents off a sandy beach.

In this activity, learners solidify their conceptualization of cells by building a model of a cell in a ziplock bag.
