In this activity about daily rhythms (on page 17 of the PDF), learners will explore circadian patterns in humans, animals and plants.

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

In this food science activity, learners conduct an experiment that demonstrates the importance of light to plants.

In this math lesson, learners construct box-and-whisker plots to analyze and compare data sets. Learners investigate whether or not long-legged people run faster than short-legged people.

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

In this "Sid the Science Kid" activity, learners get their hands dirty by playing in a container of soil. Then they compare the effectiveness of cleaning their hands with just a paper towel vs.

This is an activity (located on page 3 of the PDF under Nanosilver Activity) about diffusion of small molecules across cell membranes.

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

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

In this activity, learners will train to improve lung, heart, and other muscle endurance as they walk a progressive, measured distance.

In this activity, learners explore the "nuts and bolts" of gene chips.

In this activity (on page 12 of the PDF), learners make a sundial (shadow clock) appropriate for their geographic location in the northern hemisphere and use it to tell time.

Learners draw and cut out shapes of organs from construction paper. Then they attach these organs to the body of one learner to make a life-sized map of all the internal organs.

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

In this activity that can be used as a lab or demonstration, learners use Lactaid® and lactose to demonstrate the concept of enzyme action.

In this activity (page 10), learners explore how molecules self-assemble according to forces of attraction and repulsion.

This is an activity (located on page 3 of the PDF under Stained Glass Activity) about nanotechnology making its way into everyday products, such as sunscreen, and how effective these invisible particl

In this activity, learners build a plastic emergence chamber (or use purchased "mini mosquito breeder") to observe and analyze the mosquito life cycle.
