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 construct hand-held altitude trackers. The device is a sighting tube with a marked water level that permits measurement of the inclination of the tube.

In this activity, learners explore how anemometers work to record wind speeds and how the equipment has undergone engineering adaptations over time.

In this group or individual activity, learners are encouraged to watch birds near home or school—possibly where birds are nesting in a tree, pecking in a park, feeding from a feeder, or flying through

In this international citizen science activity, learners measure their night sky brightness and submit their observations into an online database.

In this activity, learners will engineer their own weather vane. This activity includes step-by-step instructions with pictures and a "What's Happening?" section explaining how the activity worked.

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

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.

This activity (located on page 3 of the PDF) is a full inquiry investigation into bird behaviors.

In this activity, learners build handheld rockets and launchers out of PVC pipes and plastic bottles. Use this activity to demonstrate acceleration, air pressure, and Newton's Laws of Motion.

In this meteorology activity, learners construct simple devices to measure the direction and speed of wind.

In this activity, learners use the Sun's energy to cook marshmallows. Learners construct the solar oven out of simple everyday materials.

In this activity, learners explore rocketry and the principals of space flight.

In this activity, learners will train to improve lung, heart, and other muscle endurance as they walk a progressive, measured distance.

In this activity, learners will take a walk with their family and incorporate a scavenger hunt. They will explore topics like ABC’s, numbers, colors, and shapes as they search for related items.

In this activity, learners make an equatorial sundial, which is simple to construct and teaches fundamental astronomical concepts. Learners use the provided template and a straw to build the sundial.

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.

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

Is a square stronger than a triangle? Use tongue depressors to build simple shapes. Then apply a little weight to them and see what happens!
