When they do, they learn. Using this resource, young mathematicians learn about platonic solids by actually building, touching, and examining the shapes. They connect their observations about the shapes to Euler's formula.

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...

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.

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,...

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...

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...

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,...

If you're looking to set your class up for writing effective arguments, try out this idea. While originally created with freedom as a guiding idea, the activity could easily be adapted for other themes. As a class, create a chart of...

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...

Whether or not Galileo actually dropped balls from the Leaning Tower of Pisa, this demonstration will solidly demonstrate that objects are accelerated at the same rate, regardless of mass. You will, however, need a vacuum pump and a few...

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...

When oil spills happen, how is the oil cleaned up? Pupils of polymer science discover an amazing substance that turns oil into a solid during a microscale experiment. Individuals observe oil or paraffin before and after addition of the...

You're on solid ground if you decide to use the resource. A simple activity has young engineers investigate the problem of liquefaction. A battery placed on dry sand will stay standing—but not if scholars add water to the cup.

The hunt is on! Young mathematicians follow clues and complete a series of ten math puzzles as they try to crack Dr. Integer's code and find the location of his hidden treasure.

An AP calculus lesson begins with an activity to determine the volume of a solid using a cross-section. Next, learners review the ways to find the area between two curves , as well how to find the volume of a solid created...

Present tense verbs are the focus of a 24-page packet designed for language learners and loaded with activities, worksheets, and exercises. Step-by-step directions, materials lists, and variations for each lesson are included. A solid...

Plants never grow at the same rate, and that is the antithesis for this word problem involving multiplication of fractions. On the learning exercise, Raul notices that Pablo's seedlings are 1 1/2 times as tall, and Celina's seedlings are...

Explore patterns in the multiplication table in order to deepen your third graders' understanding of this essential skill. Implement this activity as a whole-class activity, allowing students to work in pairs or small groups to support...

A straightforward and thorough packet of reading exercises would be a solid addition to any reading unit. With worksheets that address various writing and reading skills, including word roots, narrative writing, evaluating text, and...

In this interactive JeopardyLab game, with the assistance of a teacher, students can play against each other or in teams to review the content of Third Grade Social Studies. Allow the first team to choose a topic and a point value for a...

Using this interactive map activity, from A Biography of America, explore how the "New West" evolved during the late 20th century, transforming from the wild, untamed Old Rocky Mountain West into a smaller, more accessible "New West."...

This website provides several printable flashcards that can be used to teach sight words.

This video discusses family relationships at an introductory level. Some English is uttered by the Spanish speaker as well. The video will require Adobe Flash Player in order to play.

This resource provides a short experiment for students to explore how clouds are formed.
