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...

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....

Steam engines have been around since the late 1600s, yet most pupils don't know how they work. Using an soda can, the instructor builds a simple steam engine for scholars to observe. Through a discussion, young scientists learn about the...

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...

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...

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. 

Can you mix two liquids to make a solid that is insoluble? Yes, you can, and pupils see this as the lesson uses more than one combination of liquids to form a solid. Through two teacher demonstrations and a hands-on activity,...

Visibly display the location of the water in the world. Using 12 liters of water to represent the total amount of water in the world, the class measures out the water located in different areas, such as the ocean and ice caps. Class...

When a candle burns down, what happens to the mass that appears to be shrinking? Lesson begins with a demonstration of the chemical reaction of a candle burning. Then scholars use atom models to observe conservation of mass...

What's the point in saving water? Surprisingly water isn't a forever resource because it is a natural resource. Here, young water conservationists hunt for 23 wise water users and water wasters by clicking on the people in the...

It's all about freshwater in this water interactive! Users navigate through freshwater habitats such as lakes, rivers, and wetlands, taking note of the animals that live there. They also look at a desert habitat for comparison....

In a simple activity, physical scientists model nuclear fission using a droplet of oil. This can be used alone in a unit on different types of energy, or as part of the energy conservation unit produced by the Texas State Energy...

Everyone enjoys combining baking soda and water. Here is a lesson plan that challenges scholars to analyze the reaction three different ways — the real substances, the chemical equation, and the molecular models....

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...

Bubble, bubble, boil and trouble! What causes common substances like baking soda and vinegar to react the way they do? Welcome your junior chemists to the wonders of acid-base chemistry using a comprehensive and fun...

Water pollution is everywhere, and pollutants range from oil to fertilizers. Bring the concept to life by demonstrating the difficulties in getting particular pollutants out of water.

What energy conversions occur in the operation of a device? Small groups investigate devices and the energy conversions that occur. The groups create energy flow diagrams with added conversion processes for each of the devices...

In this teacher-led demonstration, your young environmentalists will observe and record how different types of water pollutants look when they are combined. From here, individuals will develop a hypothesis on how the water can be...

What should go in the trash, and what can be composted? Guide your young conservationists through the process of composing their trash with a lesson about the different ways we can dispose of garbage. Using a trash bag with clean...

What makes a watershed? What are the natural and human features of a watershed? How do human features affect watersheds? Where can I find my local watershed? These questions are thoroughly explained in an informative watershed interactive.

How many ways is water used? Indirect and direct water use are the two main ways humans use water, but the usage comes in many forms. Animals, agriculture, industries, transportation, and many more rely on water for different uses....

A spark of static electricity contains up to 3,000 volts, while a lightning strike contains around 3,000,000 volts. To understand electricity, its power, and the safety considerations relating to it learners engage in a comprehensive...

There's no time like the present for a presentation. Scholars present their claims about water management using facts, details, and examples from their research throughout the unit. Afterward, they complete exit tickets to evaluate their...

Whether you are teaching environmental science in junior high or studying recycling in kindergarten, there is something for all in this set of lessons designed for environmental education. The 110-page packet comes with tips for...
