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...

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...

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...

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...

Viewers learn how to identify the substances in a chemical reaction, how to balance it, and the different types of chemical reactions by watching a presentation that also includes a review of monomers and polymers. The presentation...

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.

Le Chatelier's interest in thermodynamics and building materials such as cement and plaster led to the Le Chatelier Principle in 1884. Activity 13 in a series of 36 extensively explores chemical equilibrium. Learners read about...

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...

Don't lift another finger, this physical and environmental science unit has everything you need to begin teaching your class about energy. Starting with a look at the greenhouse effect, these lessons and activities take young scientists...

On Earth, a candle flame points up, but on the International Space Station, it forms a sphere. Young scientists practice their skills by recording observations before, during, and after a candle burns. Chemical and physical...

RJ argues that playing the video game, Super Duo Breaker and Whoosh, is a good way to study for a quiz on weathering and erosion. The game character Mr. Breaker breaks things down and the character Mr. Whoosh carries them away in the...

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.

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...

Blast off! An engaging hands-on activity has pupils create rockets powered by Alka-Seltzer. They learn about the physics behind these rockets throughout the process.

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.

A set of 27 slides systematically shows how weathering, erosion, and deposition contribute to soil formation. Both chemical and mechanical weathering are described, as are resulting soil layers and properties. There is no longer any need...

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...

In May of 1981, the Winter Park Sinkhole in Florida first appeared and is now referred to as Lake Rose. Scholars learn about the causes of sinkholes through an inquiry project. Then, they analyze recent data and draw conclusions to...

Young scientists explore many different types of energy including light, heat, nuclear, sound, potential, and more. They match the types of energy and identify when energy transfers from one type to another.

Be at the top of the food chain when it comes to understanding marine ecosystems. The 21st installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program investigates marine ecosystems, ocean zones, and food...

If tap water is more acidic than ocean water, why are we so concerned about ocean acidification? The third installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program focuses on carbon dioxide levels in...

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...

A slide show serves as the backdrop for a activity 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...
