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 craft activity, learners create a string of cut-out moons and stars.

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

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.

In this activity, some learners pretend to be wolves, while the other learners pretend to be the prey of the wolf. The goal of the simulation is to have the wolves work together to survive.

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).

Learners place water and part of an antacid tablet in a film canister. The reaction creates a gas reaction that launches the film canister like a rocket.

In this activity (located on page 2 of the PDF under GPS: Temperate Rain Forest Activity), learners will identify a group of deciduous trees to study.

This activity is intended to familiarize learners with native Houston birds, introduce learners to tools biologists use in the field, and to enhance their observation skills.

In this activity, learners investigate soil conditions by creating a soil map. Learners record soil characteristics and compare the conditions of soil in different grid sections.

You may have tried to throw a curveball or a slider, or even a screwball, with an ordinary baseball and found it difficult to do.

In this weather forecasting activity, learners use common materials to construct a rain gauge and measure daily, monthly, and yearly rainfall.

In this activities, learners head outside and investigate trees through bark rubbings. Learners will need paper, a pencil, and some unwrapped crayons to create them.

In this activity, learners work in groups to build simple solar stills filled with salt water. After the stills are complete, learners observe what happens when they place the stills in the sun.

In this activity, learners observe the effect of transpiration as water is moved from the ground to the atmosphere.

In this activity (page 2 of PDF), learners play with a lens and a piece of paper to focus an image on the paper. Learners look at different things, and see how the lenses affect the image.

In this three part activity, learners explore and experiment with shadows to learn about the Sun's relative motion in the sky.

This fun, nighttime hands-on astronomy activity lets learners explore how long it takes for light from different objects in the universe to reach Earth.
