Lesson Number At-Home Activity
(Parental involvement and/or supervision are essential while students carry out these activities.)
4.1
Earth: A Layered Planet
Brainstorm with family members other models that can be used to roughly represent the layered Earth (e.g., the human cell: the nucleus in the centre, the nuclear membrane, the cytoplasm and the cell membrane).
4.2
Minerals: Building Blocks of Rocks
Research (via the Internet or library) your birthstone and those of your family members.
4.3
How Minerals are Mined and Processed
  1. Share what you have learned in this lesson about underground and strip mines and tailings ponds with your family.
  2. Inquire in your community about whether there are, or have ever been, any mines in the area. If so, what kind(s)?
4.4
Inquiry Investigation: Mining Chocolate Chips

Look around your home for materials other than chocolate chip cookies that could be used to conduct the investigation in this lesson. If you repeated the investigation using a new material, what changes would you need to make to the experimental design? Try it!

4.5
Explore an Issue: Mining for Minerals
Survey friends and family members to determine what position they would take if the scenario presented in this lesson were to take place in their community. Apply what you have learned to your classroom assignment.
4.6
Erosion and Weathering
Discuss with a grandparent of senior member of your community the landforms that existed in the community in their youth. Compare their descriptions to how the landforms appear today.
4.7
Learning About Soil
  1. Ask family members if they are aware of cases where many trees or other vegetation were removed from areas within your community over a long period of time. What were the results?
  2. Discuss with family members why they might use peat moss in gardening projects.
4.8
Inquiry Investigation: Components of Soil

4.9
Soil and Plant Growth
Examine the types of plants growing around your home. Are they planted in the right kind of soil? If not, how could you improve the soil conditions? (Consult the library or Internet for reference materials, if necessary.)
4.10
Case Study: Farming and the Soil
Contact family members or acquaintances in the farming community and discuss what you have learned in this lesson. Ask what measures they have adopted to manage their soil.
4.11
Erosion: Carving the Landscape
Make a list of concepts or terms that you find difficult to understand. Discuss these with family members and/or seek clarification from your teacher.
4.12
Inquiry Investigation: Mountains to Molehills

Are there any areas on your family property or on nearby properties that are susceptible to water erosion? If so, apply what you have learned in this investigation to help your parents manage the problem area.

4.13
Mountains to Rock
Go on a hike with adult family members to search for sedimentary rock formations. Examine the rock face to differentiate layers of sedimentary rock.
4.14
Fossils: Rock's Timekeepers
n/a
4.15
Case Study: Drifting Continents

Fill the kitchen sink with hot tap water, being careful to avoid burns. (a) Place cardboard cutouts of the plates into the water. Describe what happens.(b) Add a few drops of dish soap to the water. Describe what happens.

How does this help to explain continental drift? (The cardboard plates will float close together when first placed into the sink once the water has settled. When the soap is added, they move apart. This demonstration simulates how the plates moved when Pangaea broke apart. Addition of the soap simulates the forces that were at play, causing the movement of the plates.)

4.16
Moving Plates

Using two sponges to demonstrate, explain the way plates move to a sibling, parent or relative.

4.17
Inquiry Investigation: Earthquakes, Volcanoes, and Mountain Ranges
Brainstorm with family members what you think should be included in an emergency earthquake survival kit for your home. Write a list and determine a good place in your home where the survival kit should be stored.
4.18
Career Profile: Cracking the Secrets of the Earth's Crust

Visit the following site and learn how to build your own seismograph:
Build Your Own Seismograph
.

Work with an adult family member to build one and test it to see if it will differentiate wave magnitudes. Remember to wear safety glasses during construction!

4.19
Design Investigation: Preparing for Earthquakes
Research the earthquake-resistant features of the CN Tower in Toronto.
4.20
Mountains from Rocks

n/a

Top

4.21
Igneous and Metamorphic Rocks
Explore in and around your home to find examples of sedimentary rock. For what types of things are these rocks used? Why is it unlikely that you will find igneous or metamorphic rocks in Ontario?
4.22
Volcanoes: Mountains from Magma
n/a
Design Challenge

Note to parents: Since the Design Challenge may be used by teachers as a performance assessment opportunity, parents should consult with the teacher to determine the appropriate degree of parental involvement in their child's completion of the Design Challenge.

Unit Summary

The Unit Summary in your textbook lists all the learning expectations you have covered in the unit and identifies the specific lessons in which the knowledge and skills have been developed.

You can use the Unit Summary to help you create a personal study guide in preparation for an end-of-unit test:

  1. Copy down the list of learning expectations from your textbook. These are grouped under three headings: Understanding Concepts, Applying Skills, Making Connections.
  2. For each learning expectation, locate the appropriate lesson(s) in the unit where the expectation was covered. These are listed at the end of each expectation (e.g., 2.1).
  3. Flip to the appropriate lesson(s) for each expectation and make study notes of the key ideas or skills you learned.
