Why Chemistry? Why Mastery?

Just Breathe!

1. Write If you had $64,000, what would you buy, where would you go, what would you do?

2. Pair Seat 1 with Seat 2 Seat 3 with Seat 4 Read your partner your answers to the questions. Write down interesting things they say. Make sure you know their name!

3. Share Start with team member 1 Share your partner’s name and response

Goal…

Scientific Method Our way of asking questions about the world and getting answers

It’s Demo Time heat C 3 H 8 O (l)+ O 2 (g)  CO 2 (g) + H 2 O (l)

1. Observation The isopropyl alcohol burns like a candle.

2. Ask a Question How does the size of the container and the shaking affect the burning?

3. Background information What do you know about the chemicals involved?

4. Form a hypothesis Educated guess. What do you think is going to happen?

5. Materials Isopropyl alcohol Graduated cylinder Splint Lighter Tongs Bottle

6. Procedure 1.Measure out 100 mL of isopropyl alcohol using a graduated cylinder. 2.Pour isopropyl alcohol into bottle. 3.Move the alcohol around the bottle. 4.Light a splint and place into bottle using tongs. 5.Clean up!

7 & 8 Complete these on your own Remember to fill in the matching question -you may discuss quietly with your group.

-Explain why observations are important - Write detailed observations -Make inferences Today I will be able to…

Key Point 1: An observation is Gathering and collecting information (data) using your five senses and tools –Sight –Touch –Hear –Smell –Ruler –thermometer Ex: I taste that chocolate is sweet

Key Point 2: An inference is an interpretation of your observations Ex: I think this is a snickers because it tastes like chocolate and peanuts

The Difference Key Point #3: Observations are facts, and can’t be wrong. Inferences are beliefs, and can be wrong. Example: –Michael leaves the movie theatre, and sees that the ground is wet. So Michael thinks that it rained.

“Beyonce looks good” Observation or inference?

“Beyonce looks good” Not an observation!!! –It is not a fact that Beyonce looks good. –Some people disagree. This is an inference!!! –Whoever said this believes that Beyonce is attractive because of facts: she has clear skin, shiny hair, an hourglass figure, etc.

Observation or Inference? Part I This kid looks like a dork. The cowboy hat is brown. Cake tastes delicious. The bandana is red. I believe it is his birthday.

Partner Up Partners take turns answering Classify and explain why If your partner doesn’t explain why, ask them! If you disagree, you may ask your group If the whole group disagrees, all raise hands

Observation or Inference? Part I This kid looks like a dork. The cowboy hat is brown. Cake tastes delicious. The bandana is red. I believe it is his birthday.

Observation or Inference? Part II Make five observations about the classroom, and three inferences based on those observations. ObservationsInferences

Observation or Inference? Part III Partner up! Take turns with your partner Read off an observation or inference Partner must classify Write down good examples from your partner

Key Point Wrap-up #1: An observation is gathering information about the world through our five senses and tools #2: An inference is an interpretation of an observation #3: Observations are facts, and can’t be wrong. Inferences are beliefs, and can be wrong.
