Who knew that learning about the states of matter could taste so sweet? This fun hands-on lesson captures the attention of learners as they use what they know about solids, liquids, and gases to create their very own batch of ice cream.

Begin your states of matter lessons with a demonstration designed to introduce the concept that all matter has properties. Reinforce this concept through vocabulary exploration, and the creation of atom models; salt, water, and carbon...

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...

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. 

Using simple materials, an informative lesson plan demonstrates the Law of Conservation of Matter and explains how to balance chemical equations. Young chemists perform experiments, analyze reactions, and balance chemical...

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...

Did you know that jumping spiders sometimes wear water droplets as hats? A seventh grade science lesson introduces the concept of what makes up water: tiny molecules that are attracted to each other. Starting with a...

Start this mini unit on matter out by demonstrating how food coloring behaves when placed in cold and in hot water. Then have the class experiment with warm water and soap film. Pupils will learn that an increase in thermal energy also...

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...

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....

As a demonstration or as a hands-on activity, your class watches as the combination of vinegar and baking soda produce carbon dioxide gas. The intent of the lesson is to help youngsters understand that gases occupy space. It is included...

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...

Which sports drink provides the best pick-me-up after the big game or grueling workout? It may not be the one you'd think! Food science is the focus in a surprising lab activity. Pupils use colorimetry to determine the amount of protein,...

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...

I'm so cool! No, you're exothermic. This thermodynamics lab unit includes an introduction, teacher demonstrations, six labs that students rotate through each class day, homework assignments, application of knowledge, and...

Here is part one of a two-part lesson in which scholars investigate the changing states of water—liquid, solid, and gas. With grand conversation and up to three demonstrations, learners make predictions about what they think will happen...

Here is part two of a two-part instructional activity 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...

After challenging themselves to correctly choose the form of erosion and length of time required for a given landform to develop, earth science class members model mechanical and chemical weathering with various lab demonstrations over...

How is it possible for ocean water to have layers? The sixth installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program investigates factors that cause different water densities to occur. Experiments...

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...

In lab groups, young scientists place aluminum cans with a bubble-solution cap into different temperatures of water to see what size of bubble dome forms. As part of an atmosphere unit in preparation for learning about convection...

Want to use dry ice in your classroom this Halloween but you're not sure how? A thorough packet of 13 dry ice activities showcases engaging ways to bring chemistry to life this October.

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

Tiny bubbles, in my...clouds? Offer youngsters a hands-on, visual learning experience when reviewing the scientific concepts of condensation, water vapor, and the collection of droplets that make up clouds.
