Using simple materials, an informative lesson demonstrates the Law of Conservation of Matter and explains how to balance chemical equations. Young chemists perform experiments, analyze reactions, and balance chemical equations...

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...

Learners experiment with states of matter with water and ice. In this states of matter lesson, students experiment to discover what happens to water as it freezes to become a solid, ice. They observe what happens when ice melts back to...

Here is part one of a two-part lesson plan in which scholars investigate the changing states of water—liquid, solid, and gas. With grand conversation and up to three demonstrations, learners make predictions about what they think will...

Plasma is the most common phase of matter in our universe. Scholars explore the change of energy as molecules change phases of matter. They rotate through stations, graphing the changes in energy level.

How does heat move from one item to another, even when the items are in different states of matter? Pupils experiment with adding washers to hot water and adding hot washers to room temperature water to observe the heat transfer. 

Equip your chemistry class with the tools to properly understand endothermic and exothermic reactions. Young chemists collect, analyze, and graph data to determine how the Law of Conservation of Matter is applied to chemical...

Fourth graders define the states of matter and their properties. They demonstrate the air is matter and observe the effect of molecular motion through these activities.

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...

Start this mini unit on matter out by demonstrating how food coloring behaves when placed in cold and in hot water. Then have the class experiment with warm water and soap film. Pupils will learn that an increase in thermal energy also...

Did you know that jumping spiders sometimes wear water droplets as hats? A seventh grade science lesson introduces the concept of what makes up water: tiny molecules that are attracted to each other. Starting with a...

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...

Pupils explore matter by conducting an in-class experiment. They experiment with water's various forms by melting and freezing water, identifying its new shape. These observations are recorded to supplement later discussion. They also...

Learners explore the water cycle. In this earth science lesson, students observe and measure water in a closed container and in an open container. Learners record their observations and compare their sets of data to draw conclusions...

Students explore how various substances change from a solid to a liquid or from a liquid to a solid and how temperature, pressure and nature play an important role in this process. In this melting and freezing lesson,...

Climate models mathematically represent the interactions of the atmosphere, oceans, land, sun, surface, and ice. Part two in the series of four lessons looks at the role greenhouse gases play in keeping Earth warm and has participants...

Students investigate the 3 states of matter. In this physical science "matter" activity, students observe and participate in a number of demonstrations involving melting and freezing water. Students observe the effect heat has on...

Students perform experiments in pairs to visualize the changes in water during freezing and melting. In this properties of water lesson, students use their senses and inquiry tools to understand the changes in state of water. Suggested...

The first in a six-lesson mini unit, all using M&Ms® candies, this physical science activity gets kids to observe a single piece and discover what happens when it is placed in a plate of water. The activity can be used to...

Third graders investigate the three states of matter and the properties of materials as they undergo physical changes. They identify examples of each type of matter, role-play atoms in solids, liquids, and gases, and conduct an...

Future chemists practice laboratory techniques by creating a monochloramine solution. The objectives are to use of dilution, 9concentration, and measurement skills and to prepare a solution that will be used in a water treatment...

Students examine a PowerPoint production on molecules. Then they construct their own molecule and define what an atom, molecule, and matter is. They make a H2, HCI, and an H2O molecule. Finally, a drawing to accompany the actual model is...

Different substances can have different densities, but can the same substance have different densities? Lesson explores the effect of temperature on the density of water. Extension idea connects the concept of how melting ice in lakes...

Why do experiments require a control? Guide scholars through designing an experiment to see what they can do to evaporate water faster with a instructional activity that stresses the importance of controlling all variables. The...
