Not many lessons on states of matter can hold a candle to this one! Junior chemists gauge the density of paraffin in both liquid and solid phases. They fill 60 mL syringes with different materials to experiment with compressibility and...

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....

Steal cubes sink, but steal ships float. Lesson explores the density of solids as well as the density of water in determining what will sink and what will float. A hands-on group activity helps pupils see that weight and volume are...

Second graders identify the three states of matter by examining fishbowls with various contents. They discuss their observations and the characteristics of matter in each state. Pupils read the story The Rainbow Fish and look for...

It's time to get a little silly with this fun primary grade science activity. By simply combining two liquids, white glue and corn starch, a strange solid is formed, commonly known as silly putty. To ensure everything goes smoothly,...

There are underwater rivers that flow on the ocean floor thanks to a difference in density. Scholars learn about the density in both liquids and solids in the second lesson of an 11-part series. They then determine the density of water,...

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.

Students gain an introduction to our planet's solid waste problem and our personal responsibility in curbing and solving said problem through the use of Dr. Seuss' book, The Lorax. After hearing the book, class discussion follows.

Students explore the three forms of water and observe how it changes from a solid to a liquid to a gas. The concepts of condensation, evaporation and the introduction to the water cycle form the basis of this lesson plan.

Students explore the idea of consequence that every individual leaves a daily environmental footprint. They read articles about creative solutions to solid waste issues and then create an artwork from household trash.

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,...

Young scholars collect and categorize solid waste produced in the classroom. They weigh the waste that has been collected over one week's time, and separate it into recyclable and non-recyclable waste. They talk about the role of...

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 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...

Students identify and create simple geometric shapes and describe simple spatial relationships. Through discussion, hands-on activities and show and tell, they identify geometric solids in real life and create graphs of commonly found...

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...

Double the dimensions, quadruple the surface area. Pairs build similar prisms and compare the ratios of their surface areas and volumes to the ratio of the heights. Given two similar cones, partners determine the ratios of the lateral...

Students investigate melting and cooling in a range of materials.

Students create a polymer out of glue, water, and borax. They discuss the resulting substance and perform several experiments with it.

Third graders explore the capillary action of plants. They discover what makes paper "grow" when water is dropped on it. Pupils observe how paper reacts as it absorbs water. Students use a variety of saturate solutions to grow crystals,...

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...
