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.

Create airplanes from straws and geometric shapes. Test them out to see how far they can fly, or how accurately they can be aimed.

Learners will explore the concept of angular distance, and investigate why the moon appears to be the same size as the sun during a solar eclipse, despite the sun being much larger.

With little more than a plastic bottle, some vinyl tubing, and a length of PVC pipe, make a rocket and a rocket launcher and investigate how rockets fly.

In this hands-on and feet-on excursion, learners take a science walk to visualize the planet's immense size and numerous structures, without the usual scale and ratio dimensions found in most textbook

In this optics activity, learners split white light into all its component colors using three household items: a compact disc, dishwashing liquid, and a hose (outside).

In this activity, learners explore and experiment how we can use our bodies everyday to get from one place to another.

En esta tira cómica, Mateo y Cientina observan unas hormigas para contestar algunas preguntas: ¿Qué comen las hormigas?

In this activity, learners observe the moon each night for a month and draw their observations in a Moon Watch Log.

Build a pinwheel that works without wind! This activity contains steps on how to build a parachuting pinwheel out of paper, a film canister, and some brads.

In this activity, learners work in teams to study the observation skills essential to scientific research.

In this activity, learners discuss and investigate how cameras, telescopes, and their own eyes use light in similar ways.

Make a kite out of a garbage bag, shower curtain, painting tarp--anything light, thin, flexible and plastic!

In this engineering activity, learners examine bicycle mechanics and gear ratios. Learners determine which gears will help them bike a set course in the shortest amount of time.

In this activity on page 24, learners perform experiments to examine whether or not trash can float, blow around, or wash away.

This is an activity about motion, power, air and Newton’s Third Law of Motion, which states that for every action there is an equal and opposite reaction.

This is an activity to do when there is a solar eclipse!

In this activity, learners use cooperation and logical thinking to find solutions to network problems on the playground.

In this activity, learners simulate a wolf and its habitat and observe what happens when the limiting factors change over time.
