In this activity, learners will use Google Sky to observe features of the night sky and share their observations.

In this activity, learners examine body parts (including skin, scales, and skulls) from fish, mammals and reptiles. Questions are provided to help encourage learner investigations.

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 .

This open-ended art project allows learners to create their own colorful ice sculpture by using rock salt and food coloring on a solid block of ice.

Learners apply their knowledge from a previous study to identify different liquids--water, corn syrup, and vegetable oil.

In this chemistry challenge, learners discover that many chemical reactions involve heat loss or gain.

Learners are challenged to discover the relative densities of colored liquids to create a rainbow pattern in a test tube.

In this activity, learners use chemistry to “self-assemble” gummy shapes. Learners discover that self-assembly is a process by which molecules and cells form themselves into functional structures.

Young learners investigate and observe the properties of three liquids -- water, vegetable oil, and corn syrup. They use their senses to collect data and ask and answer questions.

In this chemistry challenge, learners identify an unknown white powder by comparing it with common household powders.

In this chemistry challenge, learners identify which plants have the enzyme "catalase" that breaks hydrogen peroxide into water and oxygen.

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

This is an activity in which learners create magic wands from a variety of materials making their choices by considering what kind of magic they want to make.

In this electrochemistry activity, young learners and adult helpers create a battery from a potato to run a clock.

In this activity, learners make their own "tornado" using two soda bottles and water.

In this activity about dinosaurs, learners first participate in a group discussion about where and when dinosaurs lived, how big they were, and who studies them and how.

In this chemistry challenge, learners combine acids and bases in a universal indicator to create five different colors.

This activity demonstrates the importance of wearing a helmet to protect the brain. An egg is used to symbolize a head with the shell as the skull and the inside of the egg as the brain.

In this activity, learners explore properties of water and watch evaporation happen by "painting" with water in the sun.
