Investigate a flower's power of marketing by making an imitation flower that successfully signals a bee (or other pollinator of your choice) to visit.

In this "Sid the Science Kid" activity, learners use their bodies to measure a room. Instead of inches or feet, how many kids does it take to measure the length of a room?

In this activity (11th activity on the page), learners use their sense of touch to identify matching pairs of objects hidden in bags. Learners can also play this game with partners.

In this two-part activity, learners explore the Earth and Sun's positions in relation to the constellations of the ecliptic with a small model.

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 fun activity for any size group, early elementary learners complete physical challenges while playing a game. Learners add new challenges to the "wheel of fitness" that they want to try.

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 collecting/comparing activity, learners work with samples of sand from different places like a lakefront, river, or ocean beach.

This activity uses a special paper that can create images with exposure to the Sun. Collect objects of different shapes and sizes and use them to make interesting patterns on your sun print.

In this activity, learners try to put together toy bricks—wearing oven mitts on their hands! This activity shows learners how difficult it is to build small things when your tools are too big.

Using a real-size sketch of a baby elephant's footprint, learners estimate, measure and record the width (diameter) and outside edge length (perimeter or circumference) of the footprint.

In this activity, learners explore how the application of nano-sized "whiskers" can protect clothing from stains.

In this activity, learners investigate what happens when you build up static electricity on plastic balls.

In this activity, learners explore how the application of nano-sized particles or coatings can change a bigger material’s properties.

In this story time program, young learners listen to the Dr.

In this activity, learners use cardboard bases and track tubes to make a ball run to explore the properties of mass, force, and motion.

In this physics activity (page 12 of the PDF), learners explore potential and kinetic energy by rolling different sized marbles down an inclined plane.

"Exploring the Solar System: Craters" is an active, hands-on activity that demonstrates how craters form, and what they can teach us about the history and composition of planets and moons.

The goal of this activity is to design, build and test a house or toy for an animal.

In this activity, learners will build the highest tower they can out of recycled materials.
