Clean up around your desk/table.
Make sure that you have the night’s homework

11. Any Questions?
Is there anything I forgot to cover?

12. You be the scientist… What do scientists do? Scientists Investigate
Scientists Plan Experiments
Scientists Observe
Scientists Test Results

13. What kind of scientist do you want to be?
What subjects will we focus on?

14. Theories vs Laws
What are some theories that you know about? What are some laws?
How are these similar and different?

15. Theories vs Laws
Scientific Law: Describes a process in nature that can be tested by repeated experiment.
A law allows predictions to be made about how a system will behave under a wide range of conditions.
Examples???

16. Theories vs Laws
Scientific Theory: An explanation of how a natural process works.
To be a valid theory it must:
Explain observations clearly and consistently
Be repeatable
Be able to be used to predict future results.
Examples???

17. Practice
Directions: Label each statement as either theory or law. Then, underline the word or words that helped you decide and explain your reasoning.
The continents drift at a rate of 1 – 12 inches per year. 
Continental drift is caused by convection currents
Evolution occurs because of natural selection.
Species change over time. This is called evolution.
Matter cannot be created nor destroyed. It can only change form.
Heat can cause matter to change form by accelerating particles, leading to a phase change or chemical reaction.
