Wow! Colorful and simple, these 160 slides introduce the various forms of energy, along with a relevant image. Some of the images are animations, which help beginning physical scientists to visualize the flow of electrons or energy! This...

Young scientists participate in a hands-on experiment to explore Einstein's theory of relativity in a creative manner. They investigate various waves and compare their characteristics as they discuss how each wave is created....

Students 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 or...

Roll up your sleeves and get a little dirty with this elementary and middle school compost lesson. All you need is a large plastic container, a couple old newspapers, some organic waste, and a few hundred worms and you're ready...

Ninth graders conduct research on the subject of sea water. They use a variety of resources to obtain information. There are helpful resource links listed in the lesson. In conjunction with the research students make inquiry of the...

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...

When an organism eats, how does food become energy? Young biologists follow glucose through the process of cellular respiration to the creation of ADP using a discussion-based activity. The resource also highlights conservation of mass...

Can you disprove the law of conservation of mass? Pupils observe the teacher weigh each part of a reaction. Then, the teacher weighs the result of the reaction and everyone sees that the products do not equal the reactants. Then they...

Investigate the Law of Conservation of Mass through a lab exploration. Individuals combine materials to initiate chemical reactions. They monitor for signs of reactions and measure the masses before and after the reactions for...

How did that turkey get from the early Aztec culture to your table? Learn about the history of wild and domesticated turkeys in North America, as well as their inclusion in Thanksgiving traditions, with a two-part agricultural science...

Graphic organizers, photos, diagrams, and text bring the world of chemical reactions to life. By viewing this presentation, young chemists learn how to recognize when a chemical reaction has occurred, and how to balance chemical...

Discover how the periodic table tells the story of its elements. Learners begin by studying the makeup of several mixtures. Their analysis leads to a discussion of elements and the periodic table. As they dig deeper, they understand the...

Students investigate the chemical composition of pennies dated 1983 or later. In this chemical composition of American coins lesson plan, students scratch the surface of the penny to expose the zinc core. They put the penny in...

Is it easy to make snow? Scholars use critical thinking skills as they investigate the concept of polymers by making snow. The class tests several different variables and takes measurements over the course of several days. They then...

Young scholars examine the three states of matter. They identify the segments of heating and cooling curves. Students analyze data and create a graph to determine the freezing and melting temperature of water.

Did you know that cutting down your shower by one minute a day can save five gallons of water? Learn about water conservation with a science reading activity. After kids finish reading key terms and water-saving tips in a reading...

Matrices help solve systems of equations in chemistry, computer graphics, circuitry, probability, and more. The second lesson in a seven-part series focuses on using matrices to balance chemical equations. Pupils rely on the Law of...

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...

First, young chemists practice polymer identification by density and flame tests. With the data collected, they propose a method of separating polyethylene from other plastics and determine what property makes it desirable for recycling....

Students balance chemical equations and solve for gram to mole ratios.

Students verbalize a simple particle theory, They apply their particle theory to explain what happens during chemical reactions and how this theory supports the law of conservation of matter. Pupils comprehend that the atomic theory,...

How do humans get energy since they aren't mechanical and can't photosynthesize? Learners explore this question by relating potential energy in food to human energy levels. Scholars measure the change in mass and a change in...

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...

Students, in groups, use given materials to devise a way to deposit a ping-pong ball into a paper cup that is located in the middle of a 6-foot diameter circle, while standing outside the circle.
