Whoa! What just happened? That's right, change is everywhere. But what exactly is changing? Middle school science sleuths get to the bottom of the changes matter can experience. Through simple demonstrations, engaging videos, and an...

The more things change, the more they stay the same. This unit includes seven lessons starting with physical change and moving through to chemical change. Conservation of matter is explained clearly with multiple hands-on activities and...

Take a "conservative" approach to planning your next unit on mass and matter! What better way to answer "But where did the gas go?" than with a lab designed to promote good report writing, research skills, and detailed observation....

Get the ball rolling with this upper-elementary science unit on forces and motion. Offering over three weeks of physical science lessons, this resource is a great way to engage the class in learning about simple machines, friction,...

Don't lift another finger, this physical and environmental science unit has everything you need to begin teaching your class about energy. Starting with a look at the greenhouse effect, these lessons and activities take young scientists...

Inquiry-based learning and investigations form the basis of a deep understanding of quadratic functions in a very thorough unit plan.  Learners develop recursive and closed methods for representing real-life situations,...

Building off young chemists' knowledge of the states of matter, kinetic molecular theory is the focus of the unit. Eight days of lessons including multiple demonstrations, one lab experiment, directed instruction, and worksheets,...

Excite classes with a STEM project-based learning lesson covering chemical reactions. Groups study the different types through simulations and hands-on activities. They pick one type (synthesis, decomposition, single displacement, double...

Students create relief maps of Canada and Mexico out of everyday objects like dried macaroni, dry rice, sand, etc. They create a clue card for a location game and try to stump their classmates. They host a travel fair to display their...

Students explore the geographical features of Georgia. In this geology lesson, students explore the physical regions of Georgia and make observations regarding their changes through the years.

Students analyze the physical geography of the United States and how we have adapted to or altered the land to create the country we know today. Students complete maps with physical features, states and cities of interest.

A thorough and fun lesson on Korea! In groups of four (Social Chair, Historian, Translator, Travel Agent) class members research North and South Korea to determine a good location for an overseas institute for studying abroad. Once this...

Whether democracy will ever take hold in Islamic nations continues to be a topic of great debate. Here, a series of questions, research, and discussion provide a foundation for class members to come to their own conclusion which they...

Students study the similarities and differences between Canada and the United State in this unit. They examine geography, government and culture as they "travel" through Canada.

Students explore human growth and development as they participate in class activities, reading and discussion. Worksheet and handouts are included in the lesson.

[Free Registration/Login may be required to access all resource tools.] Students explore how heat of fusion and heat of vaporization energy are used to create a phase change, and how a phase change can be used to do work.

[Free Registration/Login may be required to access all resource tools.] In this online tutorial, students will begin to understand a substance according to its physical properties. Learn to distinguish between extensive and intensive...

[Free Registration/Login may be required to access all resource tools.] In the following online tutorial students identify the chemical properties of a substance and describe chemical changes and differentiate them from physical changes....

Matter changes both physically and chemically on a fairly regular basis. Through these activities students will challenge their understanding of the changes that may take place with different types of matter.

By the end of this section, you will be able to interpret a phase diagram; state Dalton's law; identify and describe the triple point of a gas from its phase diagram; and describe the state of equilibrium between a liquid and a gas, a...

Explore the differences between chemical and physical changes, including some examples at the atomic level.

In this lesson, students match a substance with its state of matter, identify what state something is, and learn about temporary and permanent changes in matter.
