Grade 8 Fluids Chapter 7: Fluids on the Move

We live in a world full of fluids, but not all fluids are liquids. Fluids are substances that flow, so gases are fluids, too. The atmosphere that surrounds Earth is a fluid that is crucial to all life forms on the planet. Unfortunately, we harm the atmosphere when we release dangerous gases into the air from cars, factories, and landfill sites. In this course you will get questions from the textbook, students in grade 8 will try to solve them.

Grade 8 Cells Chapter 6: Organizing Cells

In Chapter 4, you learned about the characteristics of living things. Living things are often called organisms. Organisms are living systems composed of smaller parts working together to carry out the processes of life. Despite its small size, a cell is an organism whose organelles work together to keep the cell alive. An organism that is made up of only one cell is called a unicellular organism (Figure 1). Almost all unicellular organisms are so small that they can only be seen using a microscope.

Grade 8 Cells Chapter 4: The Basic Units of Life

By the end of Cells Chapter 4, you will be able to demonstrate your learning by completing this Task. As you work through the chapter, continue to think about how you might meet this challenge.


English EN Français FR
Technology comprises an entire system of people and organizations, knowledge, processes, and devices that go into creating and operating technological artifacts, as well as the artifacts themselves. Modern technology is a product of science and engineering, and technological tools are used in both fields
Science is the study of the natural world, including the laws of nature associated with physics, chemistry, and biology and the treatment or application of facts, principles, concepts, and conventions. Science is a body of knowledge that has been accumulated over time.
Engineering is both a body of knowledge—about the design and creation of human-made products—and a process for solving problems. Engineering utilizes concepts from science and mathematics as well as technological tools.

Magic Milk Experiment

When dish soap is dropped into milk, there is a swirl of activity of soap molecules finding and bonding with fat molecules in the milk. With millions of molecules swirling around looking for mates, the colors in the milk get all mixed up!

Dry Ice Experiment

Dry Ice is a fun and cold experiment. There’s many things you can create, so what can you make with dry ice?
Dry ice is a cool and a fun outdoor experiment. Have you ever worked with it? The big caution is that you don’t want to touch it less it burns your skin. Got that? So it has to be handled with tongs and/or insulated gloves.
