Though it comprises only 5 percent of the world's population, the US generates 40 percent of the world's waste. Scholars learn about landfills, their safety, and other solid waste methods. They use experiments and research to learn more....

Figure out the correct name for different three-dimensional shapes by watching the presentation on solid figures. Go through the main figures and read about the characteristics of each. Finish the topic with a multiple choice online...

Crystal comes from a Greek word meaning ice. Activity eight in a series of 36 has class members analyzing amorphous and crystalline solids and further classifying them based on their forces. They then explore solids, learning about unit...

Solids, liquid, and gas, the three states of matter, are the subject of a cross-curricular reading comprehension exercise that asks kids to first read an article about these forms, and then to respond to a series of questions based on...

After reading a short passage that identifies different types of geometric solids, kids answer a series of questions using information found in the article.

Your physical science class learns that there are three states of matter, and that adding or removing heat can cause it to change from one state to another. By the animations, printed information, and discussion between RJ and Zoe, they...

A collection of two lessons, kindergartners will identify two-dimensional shapes in solid shapes. They will develop basic knowledge of the components that make up a sphere, rectangular prism, pyramid, cylinder, cone, and cube. Young...

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.

Who likes magic shows? In the fourth of five lessons, pupils view a scientific magic trick. The ball fits through the ring easily, but then moments later, it won't pass through anymore. What changed? Can we reverse the change? Scholars...

Approximate the volume of a solid of revolution. Using a method similar to approximating the area under a curve, pupils investigate the volume of a solid of revolution. The learners use a given definite integral to find the volume of...

Make the connection between Hooke's law and elasticity with an activity that introduces the class to the behavior of elastic materials. The resource defines stress and strain to calculate the modules of elasticity of...

Time to move into the third dimension! Learn the names of the geometric solids and count faces, edges, and vertices. Then learn to recognize nets that create a given solid. 

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.    

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...

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...

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...

Model good modeling practices. Young mathematicians first learn about cross sections and solids of revolution. They then turn their attention to special right triangles and to the Laws of Sine and Cosine.

Investigate the properties of three-dimensional figures with this Arctic-themed math lesson. Beginning with a class discussion about different types of solid figures present in the classroom, young mathematicians are then given a...

Stretch one's mind about viscoelastic materials. Future engineers learn about viscoelastic materials and how they differ from solids and fluids. They discover how the molecular structures of the materials relate to their properties,...

Do solids, liquids, and gases even matter? The presentation focuses on changes in matter, including phases, Boyle's Law, Charles' Law, and physical changes. 

Investigate the volume of cones and cylinders. Scholars develop formulas for the volume of cones and cylinders in the 10th lesson plan of the module. They then use their formulas to calculate volume.

Your learners connect the new concepts of transformations in the coordinate plane to their previous knowledge using the solid vocabulary development in this unit. Like a foreign language, mathematics has its own set of vocabulary terms...

Explore finding the surface area of composite figures. Building on the previous lessons in the 29-part series, the 24th installment examines the surface area of three-dimensional solids. The focus is on decomposing composite figures and...

Learning how to regroup when subtracting numbers can be challenging and requires a solid understanding of place value. Walk your class through the steps with a clear and explicit presentation that addresses standard regrouping and...
