1. Today’s agenda Warm up Takes notes on absolute dating
Radio active dating game simulation
Venn diagram on page 46

2. Warmup: 11-20-17 How are scientists able to measure the exact, or absolute age of a rock?
Label page 45 “Absolute Dating”
Label page 46 “Venn Diagram of Absolute Dating and Relative Dating”

3. How can absolute age of a rock be determined?
By using radioactive isotopes of rocks and other materials
Atom: Smallest unit of matter. Made up of protons, neutrons, and electrons.
The number or protons and neutrons is usually the same
Neutron: Neutral subatomic particle
Isotope: an element with different amount of neutrons. Making it unstable.

4. How can absolute age of rock be determined?
Isotopes that are unstable break down.
Radioactive Decay
Half life: The time needed for half of a sample to break down further.

5. How can absolute age of rock be determined?
We look at percentage of originals to “daughters”

6. What is the best rock for radiometric dating?
Igneous

Complete the handout while going through the radioactive dating game and save and upload into focus and save.
When finished: Work on Venn Diagram p.46
Complete lesson 3 in the text book .

8. Draw a Venn diagram on page 46
In one circle you write 4 things about relative dating, in other circle you write 4 things about absolute dating and in the middle you write 3 common things about both.

9. Happy thanksgiving and I will see you all on November 27th.
