Unit Questions:• What purposes do systems serve?• How do systems affect our daily lives?• Under what circumstances can systems be modified?• How can you make a lasting change in an existing system?• How do people react to changing circumstances?
Lesson #1: Elements and Atomic structure
Objective:1. Identify the first 20 elements
2. Draw the atomic structure
What are all the materials in the world made from?
1. Everything else is made from different combinations of elements.
2. The elements are the basic building blocks of all the materials in the world.
3. Elements are made from nothing else.
7.1 What are materials made of?
Copy and complete the following table in your notebook: Periodic # Element Symbol State Uses

Until 20
Use the jars with the elements to help you
What is the difference between an element, compound and a mixture? Discuss with your neighbours and write your answer in your notebook.
Balloon Activity:1. Put the balloon over the arm on the Erlenmeyer
flask2. Place a very small amount of manganese in the
Erlenmeyer flask.3. Add 10 ml of hydrogen peroxide and immediately
put the bung on the flask.4. Record your observations
