In this activity, learners play a simple card game to learn the sequence of events in the transmission of nervous system signals.

In this biology activity (page 5 of the PDF), learners use yarn and sticky labels to build a model of a DNA strand. They discover that DNA is very long, very skinny, and packs well into cells.

This is an activity about a very important ingredient in most baked goods - gluten! Why is gluten so important? Without it, there would be nothing to hold the gas that makes bread rise.

Learners observe projectile motion by launching wooden balls off of a table top. They set up a rubber-band launcher so that each ball experiences a consistent amount of force.

In this activity, learners hook up a hair to a lever system and create a hair hygrometer to measure changes in humidity.

In this activity, learners explore how objects can have positive, negative, or neutral charges, which attract, repel and move between objects.

This lab activity has learners create a pendulum with a one-second period.

Make a rattle-like musical instrument! Shake it, hit it, spin it any way you want to!

In this math lesson, learners identify, describe, and construct the five regular polyhedra.

In this activity, learners explore dinosaur skeletons, anatomy, and locomotion. Learners compare and contrast dinosaur skeletons and drawings.

Learners create a model of a wetland to observe how it absorbs and filters water from the environment.

In this activity (on pages 34-39), learners make a fairly detailed model of DNA using licorice and gumdrops.

In this activity, learners will be working with a sort of scientific magic, capillary action! They will set up 3 cups of water of different colors, connect them with paper towels and wait.

In this outdoor activity, learners become beachcombers as they walk on a sandy beach in search of evidence of life.

In this activity, learners add food coloring to hot and cold water to see whether heating or cooling affects the speed of water molecules.

In this engineering activity (page 5 of PDF), young learners investigate how materials and design contribute to the strength of a structure, particularly walls.

In this hands-on experiment, kids use chemistry to explore whether acids or bases are better at restoring a penny’s shine.

In this activity related to climate change, learners create and explore topographical maps as a means of studying sea level rise.

In this activity, learners construct speedy vehicles made out of paper plates and powered by twisted rubber bands.

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