Learners investigate how drag affects the falling rate of objects.

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 laboratory exercise is designed to show learners how DNA can easily be extracted from wheat germ using simple materials.

Learners build a simple electromagnet, then use this electromagnet to transform a yogurt container into a working speaker. They can connect their speaker to a radio and listen as it transmits sound.

In this activity related to microbes, learners make slides of cells from an onion skin and Elodea (American or Canadian waterweed) to observe under a microscope.

In this activity, learners extract DNA from a strawberry and discover that DNA is in the food they eat.

In this activity, learners explore water pressure by conducting an experiment with a garden hose. Learners build a testing apparatus and create PVC nozzles with different sized holes.

In this activity, learners investigate procedural memory.

In this outdoor activity, learners make their own organic-rich soil. Depending on where this activity is done, learners will probably discover that their local soil is low in organic matter.

In this design and physics challenge, learners construct a cylindrical wing, fly it, make modifications, and determine how the changes affect flight patterns.

In this weather forecasting activity, learners determine the location of cold and warm fronts on weather plot maps.

In this activity (on pages 29-35), learners examine water pollution and filtration.

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

This experiment is designed to illustrate how fluids, including water, have the ability to flow.

In this activity, learners experience firsthand how marine animals' adaptive coloration camouflages them from prey.

Learners use a spring scale to drag an object such as a ceramic coffee cup along a table top or the floor.

This laboratory exercise is designed to show learners how DNA can easily be extracted from onion cells using simple materials.

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

In this activity, learners conduct an experiment to find the volume of one mole of gas. Learners capture sublimated gas from dry ice in a ziploc bag and use water displacement to measure its volume.

In this activity, learners try to float ink on the surface of water to create a pattern and then capture it with absorbent paper.
