In this math lesson, learners play a game to identify the properties of prime, composite, abundant, deficient and perfect numbers.

In this activity (page 59 of the PDF), learners spin and observe false eyelashes in jars of water (prepared at least 1 day ahead of time) to investigate the effects of different types of motion on the

In this activity about the relationship between food and energy (page 8 of PDF), learners estimate average daily baseline energy (Calorie) needs and energy needs for different levels of activity.

In this activity (page 32 of PDF), learners investigate the nutritional needs of healthy bones and muscles.

In this activity about human anatomy (page 20 of PDF), learners investigate the structure of muscles by comparing yarn and cooked meat.

In this math lesson, learners identify the likelihood of an event by using a walk-on probability scale.

Using paper, paper clips, an index card, and tape, teams of learners design flying devices to (1) stay in the air as long as possible and (2) land as close as possible to a given target.

In this graphing exercise (page 2 of the pdf), learners compare their own height to the length of various sharks.

In this activity, learners build bridges using paper and explore how much weight each bridge design can support.

Learners build a pendulum from a yo-yo, and then design their own experiment to determine what affects the pendulum's period of swing.

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 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.

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.

In this math lesson, learners use simple addition facts to compute values (in dollars and cents) for their names.

In this activity on page 7 of the PDF, learners investigate the solubility of gas in water at different temperatures. This experiment will help learners determine if temperature affects solubility.

In this activity (page 18 of PDF), learners will measure the volume of impact craters created by projectiles of different masses.

In this computer science activity about finite-state automaton (on page 45 of the PDF), learners use a map and choose various pathways to find Treasure Island.

In this physical sciences activity, learners use science to solve a "crime." Learners collect trace evidence (glitter) and explore its characteristics, such as color, size, shape, and light reflection

In this activity (on page 1), learners role play as atoms to explore how atoms can be rearranged to make different materials.
