In this activity (3rd on the page), learners conduct a series of tests to find out which of their eyes is more dominant.

In this activity about transfer of energy, learners get to build their own catapult using nothing more than a plastic spoon and some tape.

In this activity, learners cut out and assemble wheels to explore how variations in fish body structures (mouth shape/position/teeth, body shape, tail shape, and coloration patterns) allow fish to sur

In this online game, learners must purchase power plants for their city.

In this simple activity, learners discover how a mere piece of paper can be used to hold up the weight of a heavy book.

In this activity, learners will make and launch feather rockets. Lerners will use science process skils such as making predictions and measuring while launching the rockets.

In this engineering activity, challenge learners to build a tower out of 10 sheets of newspaper and 3 feet of masking tape, which can hold a golf ball balancing at the top.

In this activity, learners will explore how and why weight distribution works.

Cool off in the heat with this project! Learners use simple materials to build a fan that runs on a motor.

Learners build a small rocket using a matchstick and a piece of aluminum foil. A second, lit match launches the match rocket. This activity involves fire; adult supervision required.

In this activity (located on page 10 of the PDF), learners explore the properties of spraying and dripping water, while making art.

In this design challenge activity, learners invent a device that will make their friends and family ask, "What's buzzing?" Learners design an alarm with an on/off switch that is small enough to hide.

In this demonstration/experiment, learners discover that different colors and materials (metals, fabrics, paints) radiate different amounts of energy and therefore, cool at different rates.

En esta actividad, los aprendices leen sobre como Mateo y Cientina conducen una investigación forense para descubrir quien llevó unos dulces.

In this activity about magnetism (page 15 of the PDF), learners will explore how opposite and similar magnetic poles affect a swinging (pendulum) magnet.

In this "Sid the Science Kid" activity, learners get their hands dirty by playing in a container of soil. Then they compare the effectiveness of cleaning their hands with just a paper towel vs.

In this optics activity, learners conduct an experiment to find out why two eyes are better than one!

This activity is designed to let learners measure their reaction time or response time to something they see.

In this activity (9th activity on the page), learners work in pairs to see how their perception of touch differs from reality.

This is a chemistry lab activity about solutions (page 7 of the PDF). Learners see firsthand how chemicals in a solution can combine to form an entirely different substance.
