An educational lesson focuses on the idea of conservation of matter through a demonstration of the water cycle, a discussion of digesting food, and the path of carbon and oxygen atoms as they change form. 

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...

Whoa! What just happened? That's right, change is everywhere. But what exactly is changing? Middle school science sleuths get to the bottom of the changes matter can experience. Through simple demonstrations, engaging videos, and an...

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...

The more things change, the more they stay the same. This unit includes seven lessons starting with physical change and moving through to chemical change. Conservation of matter is explained clearly with multiple hands-on activities and...

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...

Students observe the differences between physical and chemical changes in properties. Through the use of an interactive presentation, the students compare and contrast the changes and provide supporting examples of each type of change.

Scientists have been studying exothermic reactions before they were cool. The lesson begins with a discussion and a demonstration of heat curves. Scholars then determine the heat of fusion of ice and the heat needed to...

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...

Young scientists learn that seeing isn't necessarily believing when it comes to the states of matter. After performing a fun class demonstration that models the difference between solids, liquids, and gases, children complete a series of...

Take a "conservative" approach to planning your next unit on mass and matter! What better way to answer "But where did the gas go?" than with a lab designed to promote good report writing, research skills, and detailed observation....

Fourth graders expand their knowledge about how the physical properties of a substances can be changed. They are given multiple opportunities, using first-hand experiences and familiar objects in different contexts, to identify...

Students identify the physical and chemical properties of matter. They review the types of matter. Students list the four states of matter (Solid, Liquid, Gas and Plasma). They recognize and describe the different types of matter.

Students comprehend the different phases of matter. They give examples of each phase and describe the processes of changing between these phases. Students are asked what is plasma? They are asked what is the four phases of matter? ...

Students utilize their knowledge of the physical properties of matter such as mass, volume, and density to solve a problem. They utilize the scientific method to solve a problem. Pupils analyze their data to determine whether their...

We have all heard the debate about teaching both theories, but an innovative lesson takes the discussion to a new level. Scholars research and debate Newton's Law of Gravitation versus Einstein's General Theory of...

Students analyze the causes of corrosion. In this chemistry lesson, students investigate what is necessary to cause chemical changes in matter. Students discover the causes of rust and tooth decay.

Explore the properties of gases through one activity and two investigations in which super scientists observe the changes gas makes when encountering different conditions.

Astronauts train underwater to simulate the change in gravity. An out-of-this-world unit includes three hands-on activities, one teacher demonstration, and a discussion related to some of the challenges astronauts face. Scholars apply...

Second graders discover what changes occur in various types of matter under different conditions. They make predictions about the changes in an apple left out in the air, water placed in a freezer, and a nail left in a cup of water. They...

Eighth graders observe two types of interactions in a sealed plastic bag. One bag contains baking soda and water, and the other baking soda and vinegar. They determine what evidence indicates that a chemical change is occurring.

The density of the huge planet of Saturn is 0.7 g/cm3, which means it could float in water! In the second part of 22, science pupils explore the size and order of the planets. They then calculate weight and/or gravity and density of...

Students look for examples of chemical and physical changes in the world around them and complete "What's Happening in My World" worksheet.

The sun sends the earth 35,000 times the amount of energy required by all of us on the entire planet, every day. The fourth lesson plan in the 10-part series looks at how light energy from the sun transfers into thermal energy. Scholars...
