In this collecting/comparing activity, learners work with samples of sand from different places like a lakefront, river, or ocean beach.

In this activity (on pages 13-16 of the PDF) learners investigate three mystery samples to see which one contains life. The three samples are sand, sand and yeast, and sand and antacid.

In this activity, learners explore the possibilities of clay as a natural material.

In this activity (on pages 22-24 of the PDF), learners match extreme enviroments with life forms they support.

In this outdoor activity and observation game, learners hunt for a variety of textures, colors, odors and evidence of organisms in the activity site.

This is a culminating activity which allows learners to summarize what they know about Woodlands Native Americans by creating illustrations and map symbols for a large outline map (see related Activit

In this activity, learners will investigate how craters are made and the different factors that contribute to size left from the impact.

This lesson familiarizes learners with the term "tropical belt." First, learners locate the equator, Tropic of Cancer and Tropic of Capricorn on a map and trace these lines with a crayon.

This activity (on pages 10-12 of the PDF) encourages learners to consider what makes living things different from non-living things.

In this activity, learners will create a diagram of the ocean zones and determine what organisms live in each zone.

“Exploring the Universe: Orbiting Objects” is a hands-on activity that invites visitors to experiment with different sized and weighted balls on a stretchy fabric gravity well.

In this activity, learners construct a simple air pressure launcher for paper rockets.

This is a guide for facilitating interaction at a touch tank with marine animals. The instructions are for setting up a display in an informal science center, but could work anywhere.

In this activity, learners work in groups to build simple solar stills filled with salt water. After the stills are complete, learners observe what happens when they place the stills in the sun.

In this activity (located on page 6 of PDF), learners observe and reproduce the distinctive physical features (i.e. plates, sharp spikes, long necks, deep jaws, claws) of their favorite dinosaurs.

In this activity, learners consider the water features they might enjoy at a community park--a pond, brook, water playground (or "sprayground"), or pool--and what happens to the water over time.

In this outdoor activity, learners explore UV rays from the Sun and ways to protect against these potentially harmful rays.

In this activity, learners create a biosphere in a baggie.

In this activity, learners use maps to locate the Northwest Coastal region.

This activity models the way Landsat satellites use a thermal infrared sensor to measure land surface temperatures.
