In this activity, learners will explore reptile biology by taking temperature readings in various places and comparing them.

In this activity, multiple learners will use a game with ballloons to learn about coqui frog behavior.

In this is activity about sound and vibration, learners create their own 'flutes' with drinking straws, then investigate how changing the length of the straw affects the sounds that are produced.

In this game-like activity (5th activity on the page), learners explore their auditory acuity as well as the importance of having two ears.

In this demonstration, learners observe the effects of density and pressure. A "diver" constructed out of a piece of straw and Blu-Tack will bob inside a bottle filled with water.

In this chemistry challenge, learners identify which plants have the enzyme "catalase" that breaks hydrogen peroxide into water and oxygen.

Learners smell balloons filled with different scents to guess what's inside. From this, they infer the presence and motion of scented molecules.

In this activity, learners use chemistry to “self-assemble” gummy shapes. Learners discover that self-assembly is a process by which molecules and cells form themselves into functional structures.

In this hands-on botany activity, learners sprout vegetables in film canisters.

In this activity, learners will be working with predictions with a time frame of one week, or longer. Start by planting seedlings.

In this health activity (page 3 of the PDF), learners will discover why covering their mouth and nose while sneezing is so important.

In this activity (on pages 13-16 of the PDF) learners investigate three mystery samples to see which one contains life. The three samples are sand, sand and yeast, and sand and antacid.

In this activity, learners work in small groups to match various marine animals with their different environments.

In this activity, learners capture and observe planaria, which are worms that eat tiny pond critters.

The goal of this activity is to design, build and test a house or toy for an animal.

In this fun activity about spiders, learners build and design a spider from cardstock, straw, string, and pipe cleaners.

Create an illusion where it appears that your hand has a hole in it. You'll see the results from when one eye gets conflicting information.

In this activity, learners explore the behavior of cold-blooded animals. Learners discover what happens when they change a fly's temperature.

In this activity, learners use plastic tubing and a funnel to listen to their heart. Learners also discover that if they run around, their heart pumps harder and faster, making it easier to hear.

This warm weather activity introduces learners to the impact trees have on blocking the sun's heat and reducing temperature on the Earth's surface.
