In this weather activity (page 4 of the PDF), learners will explore the water cycle through an interactive game.

Many people get water from a source deep underground, called groundwater.

This is an activity/demo in which learners are exposed to the difference bewteen hydrophobic surfaces (water repelling) and hydrophilic surfaces (water loving).

In this outdoor activity/field trip, learners catch and observe water striders to explore their movement and feeding behaviors.

In this activity, learners explore how water behaves differently when it comes in contact with "nano sand" and regular sand.

In this chemistry investigation, learners combine common cooking substances (flour, baking powder, sugar, salt, pepper, oil, water, food coloring) to explore mixtures.

In this activity, learners discover how a super-absorbing material can be used to move a straw.

In this activity, learners play with surprising sand that doesn’t get wet! Learners explore how water behaves differently when it comes in contact with "magic sand" and regular sand.

Using electrolysis, learners produce hydrogen gas and oxygen gas from water molecules in a solution.

Where rainwater goes after the rain stops? And why there are rivers and lakes in some parts of the land but not in others?

In this outdoor activity/field trip, learners locate and study plants and animals in several freshwater pond habitats.

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

In this activity (on page 14 of PDF), learners use a pan full of flour and some rocks to create a moonscape.

In this biology activity (page 3 of the PDF), learners will explore how plants turn sunlight into food through a process called photosynthesis.

In this demonstration, learners observe how liquid nitrogen both boils and freezes ingredients to make ice cream in two minutes.

In this outdoor, freshwater activity, learners explore the behavior and food preferences of crawdads (or crabs) by "fishing" for them with various baits.

In this activity, learners create a colorful bookmark using a super thin layer of nail polish on water. Learners discover that a thin film creates iridescent, rainbow colors.

In this activity, learners build an electric two-paddle boat using paint paddles, plastic knives, and empty water bottles.

In this hands-on science experiment, students combine their understanding of the different states of matter and the characteristics of various chemical reactions.

In this outdoor activity, learners explore UV rays from the Sun and ways to protect against these potentially harmful rays.
