Step 1: Grab your textbook from the book shelf Tear out chapter 2 ( pages 49-88) DO NOT STAPLE IT, I WILL PASS AROUND THE GOOD STAPLER LATER Step 2: Highlight lesson 1 chapter 2 key ideas and vocab words with definitions You new vocab words are Skepticism, Objective, Subjective, Cultural Bias, Personal Bias and Experimental Bias

2. Bias Cartoon
Step 1: pick one -Personal, cultural or experimental bias. Step 2: create a cartoon image with a story to illustrate the concept. Choose one Paragraph ( story/scenario) with an image Or Comic strip story ( at least 4 squares) Look in your book for an example

*Sit down quietly *Take out your Logbook for your science project *We will be setting this up after pictures are taken

*Grab a lab paper from the back of the room *Flip it over and copy down the data on the board on your data table *Take out chapter 1 and 2 pages **We will differentiating scientific theories and laws and discussing density and doing a lab on density to day**

5. Density lab background information questions
In the background information section of your lab paper you will answer the following questions in COMPLETE SENTENCES ( chapter 1 pages 18 & 19 will help)
What is density and write its formula.
If you place an object that is more dense than water in a cup, do you think it will sink or float? EXPLAIN
When you place a bottle cap in a cup filled with cooking oil it floats. Explain why this happens. Make sure to use science words like density.

6. Next step
Calculate all the densities for the unknown liquids on your data table You may use a calculator THEN For your hypothesis write down what you think the unknown liquids are going to do and explain why you think this

7. For your Graph and “straw” diagram
*On “straw”: write in your result color in the layer location of your results *Make sure you include all parts of the graph *You will be graphing the densities of the unknown liquids

8. For your Conclusion
Results: what happened in your experiment Claim: is your hypothesis correct, explain Evidence: what did you see happen, what occurred in your experiment Reasoning: Why did this happen, use what you learned in science
