Notes

DIG IT UP
1. Define a resource.
A “Resource” is any substance
which we need and use.
2. Define a non-renewable resource.
Non-Renewable Resources
A non-renewable resource is something
we need, or use, which CANNOT be
replaced within a reasonable time.
3. Define a renewable resource.
A renewable resource is something we need
which can be replaced within a convenient time.
4. Provide an example of each that can be used for energy.
Water is an important resource we need. It is
renewable because the natural weather cycles
bring rain to re-fill rivers and dams. Petroleum is non-renewable, because it took millions of years to form. Once it is used, it cannot be replaced in any reasonable time.
5. Provide an example of a man-made resource and name the natural resource that used to make it.

6. Provide a natural resource example and outline at least 2 properties it has that makes it
useful.
7. Define an ore.
8. Outline at least 3 steps in the exploration for resources.
9. Draw a flowchart for the processing of copper after its been mined out of the ground.
10. Define sustainability.
11. What are the 3 R’s for sustainability.
12. Select one non-renewable and one renewable resource and describe how it can be used
sustainably.
13. Explain the consequences of utilising a renewable resource faster than it can replenish.
Lift Off
1. Define a force.
2. Provide an example of a contact and non-contact force.
3. Describe friction.
4. Describe gravity.
5. Compare mass and weight.
6. List the planets and stars that exist in our solar system.
7. How many days are there in a year.
8. What are the four seasons? What causes this?
9. How long does it take Earth to rotate on its axis? What does this cause on Earth?
10. Draw labelled diagrams of lunar and solar eclipses.
11. Telescopes, space probes and rockets are all forms of technology that have assisted
humanity in better understanding space. Explain how each has assisted us in our
understanding of space.

Science Detectives
1. What are the 3 states of matter.
2. Draw 3 diagrams to represent the particle structure of each of the states of matter.
3. Describe what will happen to the particles of a solid if you add energy to it.
4. Define an atom, element, mixture, molecule and compound.
5. Draw an example of each of the above.
6. Identify 3 common compounds and identify symbol and number of the elements in
each.
7. Write the name and symbol of the first 20 elements.
8. Describe the structure of the periodic table.
9. Draw labelled diagrams of the first 10 atoms.
10. Compare a physical and chemical change.
11. Provide 2 examples of each.
12. List the forms of evidence we use to identify whether a chemical reaction has occurred.
13. Write a word equation for the reaction of magnesium metal and hydrochloric acid.
14. Describe a precipitation and combustion reaction.
Working Scientifically

different temperatures.
1. Identify the Independent, dependent and control variables in this experiment
2. What would be an appropriate aim for this experiment.
3. What would be an appropriate hypothesis for this experiment.
4. Identify the materials needed in this experiment.
5. How would you increase the reliability, validity and accuracy of this experiment.
