This is an activity (located on page 3 of PDF under Where's Nano? Activity) about identifying nanoscale objects and phenomena in today's world.

In this activity, learners participate in fun movement activities while playing on a giant game board. Use this activity to get learners involved in physical activity.

This activity helps learners visualize the Human Immunodeficiency Virus (HIV) by constructing three-dimensional HIV particle models from paper.

In a class demonstration, learners observe a simple water cycle model to better understand its role in pollutant transport.

In this activity about endoskeletons (page 8 of PDF), learners observe, compare and contrast different kinds of chicken bones, and relate their chicken bone observations to human bones.

This is a virtual representation of a sound mixer containing pre-looped sounds of animal, insect, and environmental noises.

Using a real-size sketch of a baby elephant's footprint, learners estimate, measure and record the width (diameter) and outside edge length (perimeter or circumference) of the footprint.

In this demonstration, learners observe vinegar and baking soda creating carbon dioxide (CO2) in a bottle. The gas is poured out of a bottle onto a candle flame, putting out the candle.

In this activity about food safety and nutrition, learners investigate safe food preparation by making fruit ice cream.

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 participate in a simulated dig to discover fossilized dinosaur bones. Learners take notes, make a map and propose theories about dinosaurs.

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