This is an activity (located on page 3 of the PDF) about the mixture of materials in bone and how they affect its strength.

Using a milk-based recipe, learners create "moo glue" which is basically white school-type glue. The "secret ingredient" in milk that helps make glue is a chemical called casein.

In this math lesson, learners explore the relationship between the thickness of a spaghetti bridge, the length of the bridge, and the amount of weight that can be supported by the bridge.

In this activity, learners design a bicycle helmet. Participants will explore the design of bicycle helmets to gain an appreciation for the role that helmet layers play protecting the head.

Through discussion and hands-on experimentation, learners examine the geological (ancient) carbon cycle.

This lesson focuses on how nanotechnology has impacted the design and engineering of many everyday items from paint to fabrics.

In this geology and engineering activity (page 7 of the PDF), learners build an earthquake simulator, then use it to test various building designs, exploring different materials, shapes, and design op

In this meteorological activity, learners get to build their very own anemometer (instrument for measuring wind speed) using a paper cup.

In this activity, learners count and measure kidney beans to explore natural selection and variation. Learners measure the length of 50-100 beans.

Learners build structures from spaghetti and marshmallows to determine which structures are able to handle the greatest load.

In this activity (page 1 of PDF under SciGirls Activity: Forecasting), learners will construct an air cannon by cutting a hole in the bottom of a bucket and stretching a garbage bag over the other end

This activity (on page 2 of the PDF under SciGirls Activity: Hockey) is a full inquiry investigation into how a hockey stick’s flex affects shooting power and accuracy.

Learners work in teams to design and build solar water heating devices that mimic those used in residences to capture energy in the form of solar radiation and convert it to thermal energy.

In this activity, learners test and compare the physical properties of thermoplastic polymers. Learners compare different plastics based on their color, degree of transparency, texture, and density.

In this activity, learners calculate the number of milliliters of water a nearby tree transpires per day.

In this activity with several mini experiments, learners explore the chemistry that helps scientists learn about the environment and how they can help save it.

In this very hands-on lesson, learners will investigate dendrochronology (the study of tree rings to answer ecological questions about the recent past) and come up with conclusions as to what possible

Agriculturalists have long considered mushroom growing a challenge, largely because you need a piece of benchtop equipment known as a laminar flow hood.

In this activity, learners explore how mirrors reflect light and change the way we see things.

In this activity, learners make a model of a pollution spill that occurred at Bangs Lake in Mississippi and measure water quality parameters in their model.
