In this health activity, learners explore breathing, lungs and asthma. Learners test their lung capacity by blowing air into balloons.

In this activity, learners make a paper model of a polymer, then make Silly Putty, an actual polymer.

Create a “Find Someone” list, with about 10 items, each containing a shape, number, or measurement. Can you find someone in the group with hair about 4 inches long? Someone wearing parallel lines?

In this oceanography and data collection activity, learners cast real time sea state conditions using buoys from NOAA's National Data Buoy Center.

In this activity, learners calculate the percentage of oxygen in the atmosphere by using steel wool's ability to rust.

In this ocean engineering activity, learners explore buoyancy and water displacement. Then, learners design models of deep sea divers that are neutrally buoyant.

Learners make a circuit board that has questions and answers. When the correct answer is chosen for a question, a circuit is completed and a light illuminates.

This event guide features three related explorations in which learners investigate the following science concepts: how you design and build a structure helps determine how strong it will be; different

This demonstration can be used to help learners visualize DNA by lysing (breaking open) bacterial cells on a slide and “stringing up” the DNA with a toothpick in less than one minute.

In this activity, learners observe tide pool animals in a touch tank to consider how they survive.

In this activity, learners use simple items to construct a device for indicating air pressure changes.

In this indoor and/or outdoor activity, learners make an anemometer (an instrument to measure wind speed) out of a protractor, a ping pong ball and a length of thread or fishing line.

Learners complete a series of hands-on and investigative activities to explore cumulus clouds.

This activity (located on page 2 of PDF) introduces learners to the real size of animals using nonstandard measurement.

In this activity, learners engineer a flying glider using paper hoops and a drinking straw.

In this activity, learners explore the possibilities of clay as a natural material.

In the kitchen, learners can perform their own density investigation.

In this activity, learners explore how infrared technology is used by engineers to create equipment and systems for a variety of industries.

In this activity, learners play a guessing game to explore classification.

In this activity, learners demonstrate and discuss simple circuits as well as the differences between parallel and serial circuit design and functions.
