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.

An estuary is a body of water that is created when freshwater from rivers and streams flows into the saltwater of an ocean.

In this online activity, learners make a whole rainbow by mixing red, green, and blue light. They can change the wavelength of a monochromatic beam or they can filter white light.

This activity was designed for blind learners, but all types of learners can model how vibrating particles, such as in a sound wave, bump into other particles causing them to vibrate, and that the vib

In this activity, (on page 6 of the PDF under SciGirls Activity: Dinosaurs) learners participate in a hands-on fossil excavation.

In this activity, learners perform an experiment that models a chromatography-like process called electrophoresis, a process used to analyze DNA.

In this activity, learners compare the ways of life of Plains Native Americans who hunted and moved frequently to follow the buffalo herds, and Native Americans who farmed and lived in more permanent

In this outdoor activity, learners play a game of Tag to discover how neurons attach themselves to each other to form a chain.

This activity (located on page 8 of the PDF) introduces learners to the concept of Non-point Source Pollution--what happens when rain washes garbage and other pollutants into rivers and lakes.

In this activity, leaners will observe the process of natural selection on a population of birds called 'Springbeaks' over four seasons of breeding on an isolated environment called 'Clippy Island.' L

This activity is a whole-group kinesthetic demonstration that shows learners what it means to be in a "risk group" for developing heart disease based on family history and genetics.

In this activity (page 5 of the PDF), learners will create a food web and explore food sources for different organisms. They will identify relationships between organisms in an ecosystem.

In this hands-on activity, learners track and record the passage of colored "pompom traits" through three generations of gingerbread people.

In this activity, learners are challenged to track and record the passage of colored pom poms (representing genes) through generations of a family using a pedigree.

This experiment allows learners to experience a small scale "epidemic," demonstrating the ease with which disease organisms are spread, and enables learners to determine the originator of the "epidemi

In this activity, learners consider how oil spills behave in the ocean and what impact they have on marine wildlife.

In this activity on page 8 of the PDF, learners make a slimy substance very similar to mucus, and sprinkle it with glitter to imitate the way that allergens are trapped.

This activity (located on page 4 of the PDF under GPS: Sea Turtles Activity) is a full inquiry investigation into testing a repair material.

In this water pollution activity, learners create pond water cultures and investigate the effects of adding chemicals or natural nutrients.

In this simulation activity, learners observe what can happen when ocean waves churn up water and oil from an oil spill.
