In this activity, learners investigate sound wave science, in stereo! Learners construct a "stereo" out of a metal coat hanger and piece of string to explore sound vibrations.

This activity (located on page 3 of the PDF under GPS: Farm Animals Activity) is a full inquiry investigation into raising livestock.

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 optics activity, learners conduct an experiment to find out why two eyes are better than one!

This activity is designed to let learners measure their reaction time or response time to something they see.

In this activity (9th activity on the page), learners work in pairs to see how their perception of touch differs from reality.

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

In this neuroscience activity (4th activity on the page), learners make their own set of Von Frey hairs to test detection thresholds.

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

This is a chemistry lab activity about solutions (page 7 of the PDF). Learners see firsthand how chemicals in a solution can combine to form an entirely different substance.

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

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

In this activity, learners find out what happens when they cover leaves with pieces of black construction paper. This activity shows learners that plants need sunlight to survive.

This simple hands-on activity demonstrates why the sky appears blue on a sunny day and red during sunrise and sunset.

In this quick and simple activity about reflexes (third activity on the page), learners conduct a simple test to explore the knee jerk reflex, typically conducted at the doctor's office.
