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. 

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...

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...

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 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.

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...

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...

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.

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.

How long do fresh foods last in space at the International Space Station? Which foods perish quicker than others? How can astronauts preserve their foods to make them last longer in space? Young scientists test the rates at which...

Middle schoolers support the law of conservation of matter with evidence. They discuss the changes observed from the burning of the candle, and the differences in mass which are observed when the same reaction is carried out in an open...

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...

Sixth graders complete several experiments about chemical and physical changes. In this physical and chemical science lesson, 6th graders complete 6 experiments about chemical and physical changes. Students examine the processes of...

Forests, through sequestration, capture excess carbon dioxide in our atmosphere and store it, aiding in climate change. The third installment in a four-part series on how climate impacts forests explores carbon sequestration....

Students complete a unit of activities to learn about states of matter and how to measure matter. In this matter lesson, students complete 8 lessons to learn about matter, its states, and how to measure matter.

Teaching is a balancing act! Keep things on an even keel with a comprehensive equilibrium lesson plan. The resource covers reversible and irreversible reactions, Le Chatelier's Principle, and the industrial applications of equilibrium...

Students test factors that may affect the rate at which sugar dissolve in water. They conduct two studies: One is to test the effect of temperature on the rate of solvation and the other is to test a factor which Students come up with...

The solar energy industry in the United States added more jobs in 2015 than the oil and gas extraction and pipeline industries combined. With the field growing so rapidly, it's essential to understand what solar energy is and how it...

There are underwater rivers that flow on the ocean floor thanks to a difference in density. Scholars learn about the density in both liquids and solids in the second lesson of an 11-part series. They then determine the density of water,...

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

Third graders recognize that different materials have different properties which can be observed such as texture and bouyancy, and compare and contrast, through observation, ability of some objects to float because of action of...

If the majority of our planet is covered with water, why do we need to bother conserving it? With a thorough and varied investigation into the location and types of water on the earth, learners will gain an understanding of why this...

Fourth graders complete activities to study weather and the water cycle. In this water cycle lesson, 4th graders observe a demonstration of the three stages of water. Students work in groups to complete a water cycle lab activity....

Is your class in the dark about photosynthesis? Shed some sunlight on an important biological process with a thoughtful activity. After answering questions to help determine their level of knowledge, learners work with chemical equations...
