In this craft-based activity, learners make DNA sequence bracelets that carry the code of an organism such as a human, trout, chimpanzee or butterfly.

In this outdoor activity, learners explore how a surprising number of animals use human-made litter, such as cans and crumpled paper, to find food and shelter in their environment.

Learners use chromatography to separate and analyze the mixture of pigments in leaves. Use this activity to discuss photosynthesis as well as why leaves change color in autumn.

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

In this activity, learners will use cereal to conduct an experiment and investigate how decreased bone density is related to increased risk of bone fracture.

In this technology activity, learners build an "alarming" doormat to keep siblings out of their rooms. Use this activity to teach learners about circuits, switches, and sensors.

In this activity related to music and sound vibrations, learners make a phonograph or record player out of simple materials. First, learners assemble the turntable, arm, and sound cone.

Learners use filter paper and water to analyze six different markers. They mark the paper with ink, and dip the paper in water. The water travels up the paper and dissolved ink travels with it.

In this activity, learners will examine various world data maps to combine the information and predict which areas could be tropical rainforests.

Learners combine counting, multiples, and number patterns with jumping up and down. To start, pick a counting number.

In this movement and measurement activity, learners jump as far as they can three times, and compare their longest jump to the longest jump of their friends, classmates and/or family members.

Can you deceive your eyes? When your eyes work normally, you see a nice 3 dimensional picture, but what happens when each eye sees something different?

This activity combines learning about nutrition, math of measurement and proportion, and healthy eating. Start by distributing food packages with Nutrition Facts labeled.

In this activity, learners will explore how density is affected by temperature and how that can create currents.

In this design challenge activity, learners investigate series circuits and motors to build a hand-held "kick stick." Their goal is create a battery-operated device that sends a Ping-Pong ball across

In this activity (located on page 2 of PDF under GPS: Baby Dinosaurs Activity), learners will look for a relationship between skull size and body length among various dinosaurs.

In this experiment, learners design and build a model room in a shoebox and furnish it with tiny furniture.

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 math game (Page 9 of the Are You Game? PDF), learners determine what makes a spinner fair or unfair. Learners first play a round with a pre-made spinner that isn't very fair.

This is a quick and simple demonstration about reflexes (second activity on the page).
