Daily Quiz, Jan 3x2 Your homework should be on your desk Work silently. Answers must be in COMPLETE SENTENCES. 1. Write a hypothesis for the following situation. Observation: The athletes look bigger. Question: What is the effect of exercise on muscle size? 2. Is your answer to question 2 a ‘quality’ hypothesis? Give 3 reasons why or why not. Review the purpose and the expectations of the daily quiz and when you receive credit. Review the expectations of the class and point to the board with the expectations written down and the consequences for violating expectations. Show examples of EXCELLENT answers to the exit question. Print out the exit question so they know what was being asked of them. Tell them that if I did not check their materials I will continue doing it the next time they are working independently.

Top Ten Compiled from class ideas 10 points possible per day Earn point if ENTIRE class does a top ten

Take 1 Silent It’s your time so respect yourself Watch your breath Don’t stress  Whatever happens is perfect

Binders and Challenge First do your challenge exercise on the half sheet of paper. When you are done, I’ll check it and you can set up your binder. Label your dividers (see syllabus) Write your name on the side. Markers and tape Place your work in the correct sections Example Section: Assessments

The student hears the bell ringing Guess the Rule… Column 1 Column 2 Glue feels sticky CP3 is the best player in the NBA The student hears the bell ringing The man is in a hurry Ms Hughes is 5’ 7” Pickles smell gross

Wait! Write down what you think the rule is for separating the 2 Partners share Group shares

The student hears the bell ringing Guess the Rule… Column 1 Column 2 Glue feels sticky CP3 is the best player in the NBA The student hears the bell ringing The man is in a hurry Ms Hughes is 5’ 7” Pickles smell gross

Today I will be able to… Explain why observations are important - Write detailed observations -Make inferences 8

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. Call on students to give other possible explanations.

“Beyonce looks good” Observation or inference? Team points if they know who this is (they will, of course---it’s just an easy opportunity to participate. Gotta build that classroom culture!) Ask them: O or I? Many will probably get it wrong. Then explain. Not every sentence that has the word “see” (or another one of the senses) is an observation!!!

“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. Team points if they know who this is (they will, of course---it’s just an easy opportunity to participate. Gotta build that classroom culture!) Ask them: O or I? Many will probably get it wrong. Then explain. Not every sentence that has the word “see” (or another one of the senses) is an observation!!!

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. IP part 1. If time is running short, skip IP part 2.

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. IP part 1. If time is running short, skip IP part 2.

Observation or Inference? Part II Make five observations about the classroom, and three inferences based on those observations. Observations Inferences 1. 1. 2. 2. 3. 3. 4. 5.

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.

Scientific Method Sequencing You will be assigned a step of the scientific method Without telling your group members which step you have, put your steps in order

A way to ask questions and get answers about the real world. Science The real world, your life, with fancy words Scientific method A way to ask questions and get answers about the real world.

3. Gather Background Information 1. Make an observation 2. Ask a question 3. Gather Background Information Scientific Method 4. Make a Hypothesis 5. Test the Hypothesis (Experiment) 6. Analyze Data 7. Draw Conclusions 8. Reflect

To test your hypothesis… Experiment: a test you do to answer a question

To test your hypothesis… Materials: the things you need to test your hypothesis.

To test your hypothesis… Procedure: the instructions you need to follow to test your hypothesis.

Look back to procedures I have followed during demos. What do they have in common?? Brainstorm with group…

How to plan a procedure…. Think about WHAT you MUST do! USE COMMON SENSE! THINK CAREFULLY! A ‘quality’ procedure… 1. Must be step-by-step 2. Number each step 3. Must be specific and clear 4. Last step is always CLEAN UP!

What is the point of today? To select materials To plan a procedure Important for… 1. GEE Science 2. This class 3. LIFE

Mystery Goo I stayed after school yesterday and mixed cornstarch and water together. Afterwards I noticed it had some strange properties. Sometimes it acted like a liquid and sometimes it acted like a solid. I wanted to find out what made it act like a liquid or a solid so I planned an experiment. Then, I heard a rumor that you all wanted to do labs and convinced me to let you do the experiment instead.

Remember: safety equipment! Name: _____________________ Date: ______________________ Period: _____________________ Mystery Goo Directions: With your team select materials and plan a procedure to make: A mixture that is 25 mL of water and ¼ cup of cornstarch perfectly blended together. Remember: safety equipment!

Name of equipment Graduated cylinder Drawing

Back of Card What does this tool measure? Volume …in what units? Milliliters (mL) How do I use this tool? …coming up next!

Reading the Graduated Cylinder Your eye should be level with the top of the liquid You should read to the bottom of the MENISCUS

Reading the Graduated Cylinder What is this reading? _____ mL

Expectations Always respect your environment and clean up. Be responsible and write observations as you work Be ready. Everyone in the group must participate. Follow PROCEDURE carefully…remember the “directions” exercise at the beginning of class Protect yourself and do not eat ANYTHING. Remain at your lab stations!!!

Lab Procedure Only begin with pre-lab questions done AND checked Send one to get materials Send one to get goggles for group Two clear tables Always think first, write own thoughts, share with group one at a time, then may choose to revise
