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...

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

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.

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...

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...

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...

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...

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 lesson has students line up to form human waves. Through different movements when attached,...

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...

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...

Apply robotics to connect physical properties to chemical properties. Future engineers use robots to determine the melting points of various fats and oils. The robots can do this by measuring the translucency of the fats as they heat up.

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,...

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...

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,...

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,...

Discover the properties of water-loving and water-hating surfaces. In the seventh installment of a nine-part series, scholars explore hydrophilic and hydrophobic surfaces by conducting an experiment. They observe surface coatings,...

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...

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...

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. 

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...

Subtracting negative numbers can be confusing to your middle schoolers. Here, they are able to draw a number line and put their answer in sentence form to check their understanding of negative numbers. 

The water cycle is one of earth's most easily observable processes, but demonstrating each step within classroom walls can be a challenge. Through a series of videos and quick demonstrations, cover each aspect of the hydrologic cycle in...

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.
