1 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.

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

3 Take 1 Silent Its your time so respect yourself Watch your breath Dont stress Whatever happens is perfect

4 Binders and Challenge First do your challenge exercise on the half sheet of paper. When you are done, Ill 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

5 Guess the Rule… Column 1Column 2 Glue feels stickyCP3 is the best player in the NBA The student hears the bell ringing The man is in a hurry Ms Hughes is 5 7Pickles smell gross

6 Wait! 1.Write down what you think the rule is for separating the 2 2.Partners share 3.Group shares

7 Guess the Rule… Column 1Column 2 Glue feels stickyCP3 is the best player in the NBA The student hears the bell ringing The man is in a hurry Ms Hughes is 5 7Pickles smell gross

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

9 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

10 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

11 The Difference Key Point #3: Observations are facts, and cant 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.

12 Beyonce looks good Observation or inference?

13 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.

14 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.

15 Partner Up Partners take turns answering Classify and explain why If your partner doesnt explain why, ask them! If you disagree, you may ask your group If the whole group disagrees, all raise hands

16 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.

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

18 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

19 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 cant be wrong. Inferences are beliefs, and can be wrong.

20 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

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

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

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

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

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

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

27 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!

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

29 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.

30 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: _____________________ Date: ______________________ Period: _____________________

31 Graduated cylinder Name of equipment Drawing

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

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

34 Reading the Graduated Cylinder What is this reading? _____ mL

35 Reading the Graduated Cylinder What is this reading? ____ mL

36 Reading the Graduated Cylinder What is this reading? ____ __

37 Reading the Graduated Cylinder What is this reading? ____ __

38 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!!!

39 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

40 Homework Complete any unfinished class work Do the Scientific Method in Practice Signed syllabus and letter home by Fri

41 Daily Quiz Complete your daily quiz silently. When time is up, we will grade them.

42 Daily Quiz Graded On the paper you grade write: Graded by (your name) Correct an wrong answers. Write the total correct at top. 1.B 2.D 3.C 4.G 5.F 6.A 7.E
