Open learners' eyes to the challenge of finding safe drinking water – something we often take for granted in our country. The PowerPoint presentation includes images, graphs, diagrams, and even a video to stimulate discussion on how we...

Young scientists investigate chemical and physical changes to the states of matter—gas, liquid, and solid—as well as solutions and suspensions with a variety of demonstrations, grand conversation, and an interactive quiz to check for...

Here is part two of a two-part lesson in which scholars investigate the changing states of water—liquid, solid, and gas—and how energy from heat changes its molecules. With grand conversation, two demonstrations, and one hands-on...

Super scientists visit ten stations to predict, observe, and draw conclusions about the physical and chemical changes that occur when different states of matter—liquid, solid, and gas—are placed under a variety of conditions. To...

Through a PowerPoint presentation and the embedded animation and video, earth science enthusiasts find out about the moisture in the soil beneath our feet. In the animation, follow a water molecule on its path through the water cycle. As...

Your class sets up a mini water cycle model to examine the process. Then they watch an animation, following a water molecule through the cycle. A well-developed lab sheet guides learners through the lesson plan and a PowerPoint...

Environmentalists test stream water for temperature, pH, and turbidity. Each group shares their information and then the class makes an overall evaluation of the water quality. A slide show sets the backdrop for the teaching portion and...

Environmental explorers examine the campus and take note of living organisms. Introduce them to the biosphere and the questions of the day: How much water can be found in the biosphere? A slide show helps you along, and even contains a...

A slide show serves as the backdrop for a lesson plan on the moisture in Earth's atmosphere. Through it, mini meteorologists learn about the attributes of the atmosphere and actually use data-collecting weather tools to make observations...

Winter weather offers a great opportunity to teach young scientists about the states of matter. This activity-based lesson includes a range of learning experiences, from experimenting with the rate at which ice melts...

Liquids, gases, and solids are the states of matter in which scholars investigate in a lesson plan that offers in-depth information and engaging activities that look into the three states and the changes their properties make when mixed...

Do solids, liquids, and gases even matter? The presentation focuses on changes in matter, including phases, Boyle's Law, Charles' Law, and physical changes. 

Swimmers know to float by turning their bodies horizontally rather than vertically, but why does that make a difference? In an interesting activity, scholars explore buoyancy and the properties of air and water. They test cups to see...

Global warming isn't just an issue on land; deep ocean waters are also showing troubling signs. Young scientists learn more about deep water corals and the many recent discoveries researchers have made. Then they examine data related to...

Explore the amazing power of glaciers with a hands-on earth science experiment! After first learning basic background information, learners go on to create their very own chunks of frozen water and gravel in order to...

Scholars learn about heat release in phase changes. They perform calculations as they compare and contrast a science fiction passage and a home heating application.

How much does the sun heat up a lake or ocean? Scholars use a cup and a strong lamp to investigate the heat transfer and thermal layers in the ocean to come up with the answer. They collect data and graph it in order to better understand...

Explore the world (our world) of melting ice caps. Why are these caps melting? What is the effect of melting ice caps? Dive into the ever-present issue of global warming with a resource that has learners looking at data and participating...

How do Earth's changes affect humans? Pupils learn about physical and chemical changes on Earth and how they lead to erosion, earthquakes, and volcanoes. Using the text, they also explore the concepts of electricity and magnetism by...

An inquiry-based algebra lesson explores real-world applications of linear functions. Scholars investigate four different situations that can be modeled by linear functions, identifying the rate of change, as well as the...

Some say cooking is an art—and a science! Scholars scope out the savory subject of molecular gastronomy with a series of related activities. The teacher's guide contains printable worksheets and helpful tips for implementing the lesson.

What's the matter? Gas, solid, liquid, or plasma. The presentation covers how to describe and identify matter, changes in matter, types of matter, measuring matter, particles of matter, Democritus, and John Dalton's Atomic Theory.

Once I told a chemistry joke, but there was no reaction. Get young chemists involved in changes and reactions with a presentation that begins with physical and chemical changes and chemical reactions. It moves on to chemical...

Young entomologists familiarize themselves with the physical characteristics of insects. Composed of two activities, each lesson involves your scientists tapping into their prior knowledge of bugs and making observations of real live...
