Learners discuss the idea of values and how they are different for different people and cultures. Using the Internet, they read about the Makah whaling issue affecting the Pacific Northwest. They discuss who has the right and authority...

Twelfth graders are introduced to the term Photosynthetically Available Radiation. In groups, they participate in an experiment to determine how ecosystems survive the conditions in the Arctic. They calculate the amount of solar energy...

In this literacy worksheet, students find the words that are in the word search puzzle that focus upon the vocabulary that is from the theme of the sheet.

For this endocrine system worksheet, students compare and contrast the glands associated with this body system plus review the four major classes of hormones. This worksheet has 25 fill in the blank statements.

Students learn about cells. For this cells lesson plan, students take several days to learn about plant and animal cells and make their own edible cells with a cookie and icing.

Young scholars compare and contrast the properties of substances and mixtures. In this chemistry lesson, students simulate spontaneous mixing by performing a short class activity. They differentiate heterogeneous and homogeneous...

In this PowerPoint, students participate in a game with a quiz show format in which they answer questions about water. Topics include the water cycle, bodies of water, characteristics of water, and how water relates to weather...

High schoolers participate in an activity of a mock electrophoresis using paper chromatography to study DNA and genetic restriction mapping.

Seventh graders examine different categories of plant life and their roles as producers of food and oxygen for other organisms. They study the evolution of plants from simple organisms to very complex ones. They look at the different...

Have you ever wondered how important gases enter and leave cells? Take an up close tour of a pore in a cell membrane. Then explore diffusion, osmosis, and active transport through this collection of interactive models.

By the end of this section, you will be able to define diffusion, osmosis, dialysis, and active transport and to calculate diffusion rates.

[Free Registration/Login may be required to access all resource tools.] Tutorial defines passive transport, semipermeable, and diffusion. Students will learn the significance of a concentration gradient and be able to list the three main...

A decent site with a good explanation of Graham's Law of diffusion. Includes the formula for this law and some sample problems at the bottom of the page.

This lesson is designed to give students a conceptual understanding of cultural diffusion and the notion that ideas change people and people change ideas. It involves a teacher demonstration, student role-play, and an activity that...

Learn about membrane permeability and facilitated diffusion (including channels and carrier proteins).

This paper discusses the diffusion of culture through technological change. (1997)

Brief text summary of what students learn in the Diffusion across a Selectively Permeable Membrane lab, along with links to download Student Handouts and Teacher Preparation Notes in PDF or Word formats. Main teaching points include...

[Free Registration/Login may be required to access all resource tools.] Describes passive transport and diffusion.

[Free Registration/Login may be required to access all resource tools.] Describes facilitated diffusion.

An activity to understand how diffusion is a result of random motion and collisions of particles. With the virtual labs, explore how a drop of food coloring into a glass spreads and how perfume diffuses at different temperatures and...

Explains the processes of osmosis and diffusion using labeled illustrations, discusses how they occur and gives examples.

This activity demonstrates diffusion, osmosis, and active transport through 12 interactive models. (Requires Java)

Understand the processes of osmosis and diffusion.

An interactive demonstration where students make observations of the process of diffusion. Students draw and record observations, make predictions, and make comparisons between what they're observing and how a cell membrane works.
