In this quick activity, learners explore how blubber protects animals from the cold by making a "blubber mitt." Using cooking shortening, two zip-top sandwich bags, and duct tape, learners simulate bl

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, learners conduct an experiment by heating an aluminum can filled with water to investigate air pressure.

In this quick activity about predicting (located on page 2 of the PDF under Where's Nano?

In this activity, learners identify the reproductive parts of plants and the animal (bee) structures involved in pollination.

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

In this hands-on activity, learners simulate the crashing and smashing of a meteor impact using household cooking supplies.

In this online activity, learners will explore size estimation in one, two and three dimensions. Multiple levels of difficulty allow for progressive skill improvement.

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

Did you know that the water we use today is the same water found on Earth millions of years ago? The Earth constantly uses and recycles water in a process called the water cycle.

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

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

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.

In this online activity about heart disease, learners will, with the virtual help of an actual surgeon, watch a virtual bypass surgery.

In this activity about sea otters, learners make their own "otter whiskers" and use them to find objects underwater.

This fun and simple hands-on astronomy activity describes techniques scientists use to find planets orbiting other stars.

In this simulation, learners become birds different beak types. Learners use various tools to represent beaks to pick up seeds and place them in a petri dish.
