In this activity, learners explore properties of water and watch evaporation happen by "painting" with water in the sun.

Put math of measurement into lining up — and make waiting in line fun. Choose a size characteristic that learners can physically compare, such as foot length or hair length.

In this activity, learners explore genes and traits. Learners investigate their fingerprints and learn how to categorize them.

In this activity, learners interact with a 3-D model of a watershed to better understand the interconnectedness of terrestrial and aquatic environments.

This online interactive has three activities in the NanoLab (press the upper right button): Build, Zoom, and Transform.

Everybody loves boomerangs! In this activity about force and motion, the learners will experiment with boomerangs and explore how they work. This is a great activity to get learners up and moving.

In this activity, learners manipulate paper to build original 3-dimensional sculptures. Appropriate for any age, learners can use fingers to tear, crumple, or fold, and if available, scissors to cut.

In this outdoor water activity, learners explore evaporation by painting with water and tracing puddles. Learners will discover that wet things become dry as the water evaporates.

In this activity, learners will swirl paint into shaving cream to make an extravagant nebula print.

In this activity, learners engineer a paper helicopter that spins to the ground when dropped.

In this activity, learners build an instrument for catching and observing flies. Learners act as entomologists, attract flies into a jar using a slice of apple, and then observe the flies' behavior.

In this activity, learners perform a plant dissection to gain a better understanding of a plant’s structure and function.

In this activity, learners will explore how light can refract or break apart into different colors.

Make a camouflage cut-out animal! Using patterned paper or magazine pictures from around the house, use your craft skills to make a paper animal that blends into its background.

In this activity (on pages 55-66 of PDF), learners fold paper into origami shapes and then combine several identical shapes into a three-dimensional structure.

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

In this activity (located on page 2 of PDF), learners sing together a song that gives details about the dinosaur species Suchomimus (pronounced “Sook-o-mime-us”).

In this activity, learners interact with whale artifacts such as replicas of skulls, bones, teeth, and baleen (hair-like plates that form a feeding filter).

In this activity, learners build their own rockets from paper, coffee stirrers, and tape. Learners discover that when anything flies, air pressure is always involved.
