In this activity (page 105 of the PDF), learners measure heart rate and blood pressure and learn how to obtain consistent measurements during repeated tests.

This lesson focuses on how to measure at the nanoscale and provides learners with an understanding how small a nanometer really is.

Millions of organisms can live in and around a body of water.

In this math lesson, learners predict, interpret, and sketch graphs of functions related to the shapes of bottles. A measure of water is poured into a container.

In this activity, learners explore and experiment how we can use our bodies everyday to get from one place to another.

In this math lesson (page 2 of the PDF), learners use bottles of various shapes to explore the abstract concept of rate of change.

To learn how friction affects motion, learners build a measurement tool from a rubber band and other simple materials.

In this activity about the brain and sleep (on page 138 of the PDF), learners measure their resting breathing rates. Learners will discover that breathing frequencies vary amongst individuals.

In this activity, learners make an equatorial sundial, which is simple to construct and teaches fundamental astronomical concepts. Learners use the provided template and a straw to build the sundial.

In this activity, learners calculate the percentage of oxygen in the atmosphere by using steel wool's ability to rust.

Learners construct and launch paper helicopters.

In this activity (1st on the page), learners explore circadian rhythms by keeping track of their body temperature.

In this health activity, learners create a device so that they not only feel their heartbeat, but also see it, using a straw and some clay.

Learners create a tool to measure how well they grip a wet object when their fingers are smooth versus wrinkly. Are smooth or wrinkly fingers better at holding on to the object?

In this lab activity, learners explore how to initiate a density current. Learners measure six flasks with different concentrations of salt and water (colored blue).

This activity (located on page 3 of the PDF under GPS: Glaciers Activity) is a full inquiry investigation into the forces of gravity and air pressure.

In this environmental health activity, learners investigate their breathing and pulse rates, and learn how these measurements are affected by physical activity.

Learners investigate why the Sun and Moon appear the same size in the sky even though the Sun is over 400 times larger in diameter.

In this inquiry-based lesson, learners measure the biomass of trees, calculate the carbon stored by the trees, and use this information to create recommendations about using trees for carbon sequestra

In this activity, learners observe the effect of transpiration as water is moved from the ground to the atmosphere.
