In this activity, learners explore reaction time and challenge themselves to improve their coordination. Do you want to move faster? Catch that ball that you never seem to see in time?

Learners develop awareness and understanding of the daily air quality using the Air Quality Index (AQI) listed in the newspaper or online.

In this activity, learners construct possible food webs for six different ecosystems as they learn about the roles of different kinds of living organisms.

In this activity, learners of all ages will design a functional bird feeder using familiar, every day materials.

In this activity, learners discover that our hands are not reliable thermometers.

In this activity (on page 142 of the PDF), learners will compare breathing rates before and after hyperventilation to explore how reduced carbon dioxide levels in the blood lower the need to breathe.

This resource contains several mini-explorations using a slide projector as a light source to investigate light and the properties of images.

In this activity (page 87 of the PDF), learners move their bodies to better understand the three axes of rotation: pitch, roll and yaw.

This lesson gives full instructions for making cabbage juice indicator, a procedure sheet for learners to record observations as they use the indicator to test materials, and extension activities to d

In this activity, learners discover how artists start with a skeleton and turn it into a realistic drawing of a dinosaur.

In this activity, learners examine the properties of different seaweeds, investigate what happens when powdered seaweed (alginate) is added to water, and learn about food products made with seaweed.

Learners design their own experiment to determine conditions that either help or hinder the decomposition of carrots by soil microbes.

In this activity on page 11 of the PDF, learners follow simple steps to recycle old newspaper into new paper.

Most people break at least two bones in their lifetime. In this activity, learners will use celery stalks to model the many ways that bones can fracture.

This fun and simple hands-on astronomy activity illustrates the path of light as it reflects off of mirrors and how this is used in telescopes.

In this activity, learners construct a cereal chain as a model of how proteins are made in the cell.

In this online activity, learners create monsters and see how they survived when released into the wild.

In this activity on page 5 of the PDF, learners compare water with artificial urine to see how urinalysis works. Learners use urinalysis test strips to test for glucose and protein in the fake urine.

In this activity, learners explore how their depth perception would be affected if they only had one eye. Learners work in pairs and attempt to drop a penny in a cup with one eye covered.

Although we may not admit it, all humans fart or pass some gas. In this activity, learners make their own model to mimic food passing through intestines and discover what releases gas.
