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...

There's a container for every matter—liquid, solid, and gas. Pupils design three different containers, each with the capability to hold one of the states of matter, and share their design with the class.     

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...

Explore the concept of density within states of matter—gases, liquids, and solids—through a group experiment in which young scientists test objects' texture, color, weight, size, and ability to sink or float.    

Explore the unique characteristics of polymers. A complete lesson begins with a presentation introducing polymers. Following the presentation, young scientists develop a laboratory plan for creating substances using polymers. They...

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...

Enhance your states of matter lessons with a hands-on science investigation that compares six different balls' color, texture, size, weight, ability to bounce, and buoyancy. 

It doesn't matter if you look on land, in the air, underground, or in water—evolution is everywhere. Scholars complete worksheets with multiple question types as they progress through six online missions creating phylogenic trees. 

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 lesson 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 one hands-on...

Teach young engineers that all machines, no matter how complicated or complex, are made up of just six simple devices with this hands-on physical science instructional activity. Using the included templates, students first create...

How can you tell if a microorganism is helpful or detrimental to an ecosystem? Learners inspect slides or pictures of microorganisms and record their observations to...

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

Rain, rain, go away—wait, there it is again! Elementary scientists learn how rain works its way through the stages of the water cycle with a series of classroom lessons and hands-on activities.

Young scientists construct an understanding of molecular compounds in this hands-on science lesson. Using LEGO® to model the atoms of different elements, students build molecules based on the chemical formulas of common compounds.

Get your hands dirty with an interactive lesson that showcases the process of decomposing and returning nutrients back into the soil. After building a compost pile, pupils regularly observe the...

Difficulties with brain injuries still continue today. After reading Phineas Gage: A Gruesome but True Story About Brain Science, class members read a series of modern personal essays about brain injuries and choose an essay to compare...

It all becomes a matter of timing. Groups use a variety of resources to research the history of vaccines by first creating a timeline of vaccine research using leading scientists' work. Learners read articles to develop a story of the...

It's time to get to the heart of the matter! After introducing the heart anatomy in the previous instructional activity in a series on the systems of the body, the instructional activity looks at the specifics. Learners complete a series...

Clean up the environment with a lesson that focuses on replacing hazardous cleaning supplies with green, environmentally-friendly products. Using a dirty patch of surface as a control area, kids clean other parts of various surfaces...

Over a period of 35 years, earthquakes and volcanoes combined only accounted for 1.5 percent of the deaths from natural disasters in the United States. The 15th lesson in a 20-part series connects the locations of earthquakes and...

Did you know there are at least 12 different energy sources? Scholars apply their knowledge about the different types of energy as they sort energy sources by renewable and nonrenewable. Then they pick one from each section to...
