Here's a tip: only one substance is commonly found as a solid, liquid, and gas. Learners use that knowledge as they investigate the properties of water in each state. They interact with water in each of its three phases and record what...

The state of molecules is changing. Young actors and actresses perform the process of phase change in front of the class. They assume the roles of water molecules and, as a group, show how the behavior of the molecules in the solid,...

There are three basic states of matter: Solid, liquid, and gas. Help your learners with visual impairments to understand the chemical nature of each state of matter with tactile elements. Marbles are used to model the particles in each...

Tall and skinny or short and stout, which glass hold the most liquid? Learners analyze dimensions of cylindrical glasses to determine the one holding the greatest amount of liquid. They brainstorm the relevant dimensions before making...

Help classes understand heat as a form of energy. A hands-on activity has learners investigate how heat, or the lack of heat, affects the physical state of water. They then connect their discoveries to the water cycle.

Groups suspend objects within layers of liquids to determine the densities of different liquids and compare them to the densities of objects calculated in Part 1. The groups then carefully test their calculations by layering the...

Seismologists use the direction and arrival times of p waves and s waves to determine the distance to the source of an earthquake. The engaging instructional activity has students line up to form human waves. Through different movements...

Don't be so dense that light bends around you; study the relationship between mass and volume instead. Young chemists measure the density of a variety of liquids and solids. A reading passage and analysis questions introduce pupils to...

Create a cushion of carbon dioxide gas to float some soap bubbles on. Many concepts can be demonstrated through this activity: Carbon dioxide gas is more dense than air Bubbles are semipermeable, allowing only carbon dioxide to diffuse...

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

Pour a solid foundation of engineering into the minds of future engineers. Scholars take part in three activities to learn about civil engineering. They build a model of a cable-stayed bridge, conduct an experiment to see the effects of...

Let's have a gas. Individuals mix baking soda and vinegar in a bottle. Learners view the interaction between the solid and the liquid and notice that a gas is formed. Scholars notice the gas inflates a balloon stretched across the mouth...

Watch red cabbage juice turn green. Pupils first watch a video that takes them through the process of creating red cabbage juice. They then add various solids and liquids to the juice and use the color change to determine whether the...

Mold your learners into materials engineers. Using glue, Borax, and water, scholars create a viscoelastic material. But your class might know it by another name—Silly Putty.

Whether you're using a collection of Dr. Seuss books to teach basic math skills like counting, adding, and subtracting, or exploring the different states of matter by melting a crayon with a hairdryer, a series...

Seventh grade scientists weigh in on the concept of density. In a nutshell, they participate in the following activities: Measurement of the mass and volume of fruit in order to compare densities Measurement of the mass of oil and water...

The earth is a delicate and fragile thing; Why not engage your class in a craft project that will make them aware of our environment? Earth Day is celebrated as recycled materials are used to create earth window hangings. Crayons are...

Students make glue out of milk and vinegar. In this chemistry lesson plan, students combine curds of milk with an ammonia solution until a creamy liquid forms.

Geology rocks — literally! A geology chapter offers eleven activities at four different levels. Scholars enjoy completing hands-on experiments before applying critical thinking skills following a share, process, generalize, apply,...

After collecting carbon dioxide bubbles from a cup of club soda, learners attempt to make their own lemon soda while preventing the loss of carbonation. They do so by creating a syrup before mixing the substances into the club soda....

Students research elements on interactive Internet periodic tables, take notes using Inspiration software, and write descriptive paragraphs with graphics. They create presentations.

How are maps like fish? They both have scales. The chapter includes six different activities at three different levels. Scholars complete activities using natural resources, learn how to read a map, see how to make a compass rosette,...

Create an edible model of the Earth using crispy rice cereal, marshmallows, and chocolate, yum! Model layers include the outer core, inner core, mantle, and crust. 

You don't want to flush your money down the drain! Have your classes complete a financial comparison between two different types of toilets. They use linear modeling to determine the most cost-effective model.
