In this activity, learners are challenged to track and record the passage of colored pom poms (representing genes) through generations of a family using a pedigree.

In this activity, learners use a compact disc to make a spectrometer, an instrument used to measure properties of light.

In this activity, learners discover how their heart rate changes in different situations.

In this outdoor activity, learners use only their senses to to find the extremes of several environmental variables or physical factors: wind, temperature, light, slope and moisture.

In this activity (3rd on the page), learners investigate circadian rhythms by examining how well people do with estimating time.

In this activity (located on page 4 of PDF), learners gain insight into the actual size of dinosaurs and practice making estimations and measurements.

This activity lets learners participate in the process of reconstructing a phylogenetic tree and introduces them to several core bioinformatics concepts, particularly in relation to evolution.

In this activity, learners are challenged to eat some candy as a cell would need to as well as to think about some of the problems that arise when a cell ingests food.

In this experiment, pairs of learners explore how cold water affects circulation. The mammalian diving reflex (MDR) slows circulation when the body is exposed to cold water.

In this activity (page 1 of the PDF under SciGirls Activity: Bogs), learners will test cups full of potting soil, sand, and sphagnum moss to see which earth material is able to soak up the most water.

To discover the risk and protective factors involved in substance addiction, learners play a game of chance to determine whether a fictitious child is likely or unlikely to abuse drugs.

In this food science activity, learners observe different plant-originated foods.

In this outdoor, winter activity, learners find living green plants under the snow and determine the light and temperature conditions around the plants.

In this health and fitness activity, learners focus on the importance of daily physical activity, specifically walking.

In this activity (on page 2 of PDF under GPS: Sea Turtles Activity), learners will model how a sea turtle population changes over time, from eggs to adults, using puffed rice.

In this artistic activity, learners blow up a smaller picture into a larger one, by using a grid.

In this activity, learners will explore nature by creating food for birds. Learners will develop fine motor skills and engage in nature observation through this activity.

In this activity, learners explore the great pump in their chests--the human heart!

In this craft activity, learners will recognize, name, and compare the fractions 1/2, 1/4, and 1/8 by constructing a penguin out of portions of paper circles.

These math posters have questions written on them, such as: How fast can a cheetah run? or How long can a giant tortoise live? Post these around the room or leave them out for children to explore.
