Chemistry<br />
The Earth and its atmosphere<br />
Objectives:<br />
• Explain the processes which contributed to the formation of the<br />
modern day atmosphere<br />
• Describe the layered structure of the Earth<br />
• Explain how the rock cycle leads to the formation of<br />
sedimentary, igneous and metamorphic rocks<br />
Description<br />
Uses interactive animations to show the evolution of Earth and atmosphere from formation to 4500<br />
million years ago, the Earth’s layered structure, how rock is recycled in the crust, and the formation<br />
of the three major rock types.<br />
Duration (lesson and worksheet together): This lesson lends itself to presentation as two or three<br />
different lessons of 20-30 minutes each.<br />
Topic: Earth and its atmosphere<br />
Bonding and formulas<br />
Objectives:<br />
• State that different atoms can make different numbers of covalent<br />
bonds, and name <strong>com</strong>pounds with covalent bonds<br />
• Describe the relationship between the group in the Periodic<br />
Table and the number of bonds<br />
• State that for simple negative ions the charge is the same as the<br />
number of covalent bonds<br />
Description<br />
Uses a flexible model for exploring a range of covalent and ionic <strong>com</strong>pounds, and for displaying their<br />
names and formulas.<br />
Duration (lesson and worksheet together): 50 minutes<br />
Topic: Formulas and equations<br />
Balancing equations<br />
Objectives:<br />
• Identify the reactants and products in a chemical reaction<br />
• State that atoms are rearranged during a chemical reaction<br />
• State that no atoms are created or destroyed during a chemical<br />
reaction<br />
• Write and balance symbol equations for reactions<br />
Description<br />
Uses an interactive model to demonstrate why chemical equations are balanced, and how to balance<br />
them.<br />
Duration (lesson and worksheet together): 50 minutes<br />
Topic: Formulas and equations<br />
