In this activity, young learners will describe objects by their properties and sort by color, weight and texture. This activity uses household items and toys for materials.

In this demonstration/activity, learners observe as a regular size marshmallow is blown through a tube made from a manila file folder.

This activity provides instructions for making an aircraft that can really fly using a straw and paper hoops!

In this activity, learners will learn about a person they admire (famous, family or otherwise) or even themselves and create a life-sized silhouette.

In this activity (on pages 15-18 of PDF), learners make a life-size two-dimensional paper model of their own skeletons.

This activity was designed for blind learners, but all types of learners can have a tactile opportunity to construct a karyotype, an organized model of an organism’s chromosomes, conveying the chromos

In this activity, learners work together to create a life-sized drawing of the human nervous system.

In this math activity, learners create their own units of measurement by making noodle rulers. Learners practice estimating and measuring objects using the noodle rulers .

In this demonstration, learners observe the effects of air pressure. They will watch as marshmallows inside a bottle expand as a vacuum pump removes air from the bottle.

In this combination chemistry and physics activity, learners explore water absorption in dried beans or peas and learn how this affects their physical properties.

In this math activity, learners trace their hands and estimate the number of beans that can fit into their hand tracings. Then, learners glue the beans to the tracing to test out their estimations.

Get all wrapped up in a lesson about skin!

In this activity, learners compare different types of salt crystals under a magnifying glass.

In this activity, learners use a straight line to learn about circles. Learners measure and record the diameter and circumference of different sized cylindrical objects on a chart.

In this activity on page 5 of the PDF (Plants—The Green Machines), learners use chromatography to separate and identify pigments within various leaves.

In this activity, learners explore the chemical reaction between water and effervescent antacid tablets. This hands-on activity models how a material can act differently when it's nanometer-sized.

In this activity, learners investigate static electricity using everyday objects at four different stations.

This hands-on activity demonstrates how a material can act differently when it's nanometer-sized.

In this activity, learners build a LEGO® structure while wearing mittens. This activity shows learners how difficult it is to build small things when your tools are too big.

In this activity, learners investigate the formation of craters. Learners will examine how the size, angle and speed of a meteorite's impact affects the properties of craters.
