In this activity, learners investigate the touch sensory system and discover how to plan and carry out their own experiments.

In this math activity, learners use cubes to calculate how many blocks it would take to build stairways with different heights.

In this genetics activity, learners discover how to extract DNA from green split peas.

In this activity, learners build bridges and cantilevers in a series of "building out" challenges with straws and pins.

In this activity, learners create a model of a neuron by using colored clay or play dough. Learners use diagrams to build the model and then label the parts on a piece of paper.

In this activity, learners investigate the sense of sight and develop and conduct their own experiments.

In this activity about molecular diffusion (located on page 2 of the PDF under Nanosilver Activity), learners will make predictions and move molecules of iodine through a seemingly solid plastic sandw

In this activity, learners explore fractions as they help gators share pies.

This math challenge, played with two players or a whole group, engages your problem solving skills.

In this math activity, learners make a set of fraction cards to play a game that will help relieve their fraction frustrations.

In this math game (Page 6 of the Are You Game? PDF), learners examine the probability of rolling sums from 0 to 12 with two dice. The first player to reach the finish line is the winner.

In this kinesthetic activity that demonstrates pressure, learners act as air molecules in a "container" as defined by a rope.

What causes frost to form on the outside of a cold container? In this activity, learners discover that liquid water can change states and freeze to become ice.

In this design challenge activity, learners invent a pinball-like game where a kick stick hits a ping pong ball into a target that buzzes.

In this two-part outdoor activity, learners conduct a population census of squirting clams on a beach or mudflat, and investigate the clams' natural history.

In this activity (located on page 9 of the PDF), learners are introduced to Aesop's fable, "The Crow and the Pitcher." In the story, a clever crow drops pebbles into a pitcher to cause the water level

In this creative activity, learners will find out what makes an insect an insect by studying examples of insect adaptations and by examining why there are so many different types of insects.

This activity shows learners how computers use numbers to represent pictures. A grid is used to represent the pixels (short for picture elements) of a computer screen.

In this health and genetics activity, learners determine whether tasting the bitter compound PTC (phenylthiocarbamide) influences which vegetables a person likes.

In this simulation activity, learners will raise a pack of wolves under ten different conditions: without human interference and with human interference.
