In this weather activity (page 1 of the PDF), learners will construct their very own anemometer to measure wind speed.

Why should we wear masks? Do masks work? Do some masks work better than others? Learners find out in this activity.

In this physics activity, learners experiment with pulleys and find that they can decrease the effort needed when using a pulley to lift or move different loads.

In this outdoor activity, learners investigate spider webs and feeding behavior, particularly how spiders trap food in their sticky silk webs while not getting stuck themselves.

In this activity, learners discover the difficulty of ocean exploration by human beings as they investigate water pressure.

In this hands-on activity, learners will construct a scuba diver that can float in order to explore how sea creatures stay neutrally buoyant in the ocean and to see what kinds of forces might be influ

In this activity, learners are challenged to build a bird feeder using recycled materials from home and are encouraged to problem solve during the extensions.

In this physics activity, learners build their own rockets out of film canisters and construction paper.

The goal of this activity is to build a miniature bobsled that is either the fastest or the slowest. Learners use recycled materials to design, build, and test their bobsled on a bobsled track.

This fun and simple hands-on astronomy activity lets learners make 3-dimensional models of the Earth and Moon.

Doctors often send a sample of blood to a lab, to make sure their patients are healthy.

This activity is about the mural making process done about 9,000 years ago in Catalhoyuk, Turkey.

In this chemistry activity, learners will test the pH of various foods and household substances using cabbage.

This activity (located on page 3 of the PDF under GPS: Alligator Habitat Activity) is a full inquiry investigation into organisms and the health of their ecosystems.

In this four-part activity, learners explore how the body works and the chemistry that happens inside living things.

In this physics activity, learners build a toy with a figure that spins around like a gymnast on the high bar.

In this fun snack and craft activity, young learners make "Ants on a Log" and their own model of an insect. The purpose is to learn the three main insect body parts—head, thorax and abdomen.

In this activity, learners explore electronics and motion by making a Scribbling Machine, a motorized contraption that moves in unusual ways and leaves a mark to trace its path.

In this activity, learners build a stuffed-animal zip line. Learners hold a cord against a wall, hook a cute stuffed animal onto it, let the animal slide down, and records its travel time.

In a class demonstration, learners observe a simple water cycle model to better understand its role in pollutant transport.
