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.

Learners work in pairs to design, construct, and test a device that exhibits positive, neutral, and negative buoyancy. They test a number of different objects in water to see if they sink or float.

In this activity, learners apply Ohm’s Law to construct voltage divider circuits. Learners discover how to read resistor codes and calculate resistor values.

In this math lesson, learners compare pattern blocks to visually understand halves, thirds, and sixths.

In this activity, learners observe colors in the flame of a burning candle to explore connections between matter, light, color and temperature -- basic concepts of matter and energy.

In this game, learners match descriptions of marine debris (shoes, batteries, paper towels, etc.) to images of these items.

Learners build models of sinkholes to gain an intuitive knowledge of their physical aspects.

In this activity, learners explore how engineers use scales and measures when designing a manufacturing process to ensure that final products are uniform in weight or count.

In this activity, learners explore chemical engineering and how the processes of chemical plating and electroplating have impacted many industries.

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.

Learners mark their traits for tongue rolling, PTC tasting (a harmless, bitter chemical), and earlobe attachment on tree leaf cut-outs.

In this activity, learners explore patterns and sequences as they observe fictional plant growth.

In this math activity, learners build Peppy the dog the best trail and park for running around.

In this "Sid the Science Kid" activity from Episode 106: My Mushy Banana, learners explore the effects of decay by comparing and contrasting something (an old pumpkin) that's decayed with the same thi

In this math activity, learners pretend there is a special store that lets you pay for toys by their height in pennies.

In this quick activity (page 2 of PDF), learners will play a game using their observation and listening skills, interpreting clues from each other to deduce their secret animal identity.

In this activity, learners use what they know about probability to figure out what is in a mystery bag. Learners analyze data to guess how many of each color crayons are in the bag.

In this quick activity (located on page 2 of the PDF under GPS: Balloon Fiesta Activity), learners will see the effects of convection and understand what makes hot air balloons rise.

In this math activity, learners pretend there is a special store that lets you pay for toys by their weight in pennies.

In this quick and easy activity and/or demonstration, learners use two empty soda cans to illustrate Bernoulli's principle.
