Presentation on theme: "Daily Quiz, Jan 3x2 Your homework should be on your desk"— Presentation transcript:
1Daily 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.
2Top Ten Compiled from class ideas 10 points possible per day Earn point if ENTIRE class does a top ten
3Take 1 Silent It’s your time so respect yourself Watch your breath Don’t stress Whatever happens is perfect
4Binders and ChallengeFirst 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 tapePlace your work in the correct sectionsExample Section: Assessments
5The student hears the bell ringing Guess the Rule…Column 1Column 2Glue feels stickyCP3 is the best player in the NBAThe student hears the bell ringingThe man is in a hurryMs Hughes is 5’ 7”Pickles smell gross
6Wait! Write down what you think the rule is for separating the 2 Partners shareGroup shares
7The student hears the bell ringing Guess the Rule…Column 1Column 2Glue feels stickyCP3 is the best player in the NBAThe student hears the bell ringingThe man is in a hurryMs Hughes is 5’ 7”Pickles smell gross
8Today I will be able to…Explain why observations are important - Write detailed observations -Make inferences8
9Key Point 1: An observation is Gathering and collecting information (data) using your five senses and toolsSightTouchHearSmellRulerthermometerEx: I taste that chocolate is sweet
10Key Point 2: An inference is an interpretation of your observationsEx: I think this is a snickers because it tastes like chocolate and peanuts
11The DifferenceKey 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.
12“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!!!
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.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!!!
14Observation 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.
15Partner 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 groupIf the whole group disagrees, all raise hands
16Observation 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.
17Observation or Inference? Part II Make five observations about the classroom, and three inferences based on those observations.Observations Inferences4.5.
18Observation or Inference? Part III Partner up!Take turns with your partnerRead off an observation or inferencePartner must classifyWrite down good examples from your partner
19Key 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.
20Scientific Method Sequencing You will be assigned a step of the scientific methodWithout telling your group members which step you have, put your steps in order
21A way to ask questions and get answers about the real world. ScienceThe real world, your life, with fancy wordsScientific methodA way to ask questions and get answers about the real world.
223. Gather Background Information 1. Make an observation2. Ask a question3. Gather Background InformationScientific Method4. Make a Hypothesis5. Test the Hypothesis(Experiment)6. Analyze Data7. Draw Conclusions8. Reflect
23To test your hypothesis… Experiment: a test you do to answer a question
24To test your hypothesis… Materials: the things you need to test your hypothesis.
25To test your hypothesis… Procedure:the instructions you need to follow to test your hypothesis.
26Look back to procedures I have followed during demos. What do they have in common??Brainstorm with group…
27How to plan a procedure…. Think about WHAT you MUST do!USE COMMON SENSE! THINK CAREFULLY!A ‘quality’ procedure…1. Must be step-by-step2. Number each step3. Must be specific and clear4. Last step is always CLEAN UP!
28What is the point of today? To select materialsTo plan a procedureImportant for…1. GEE Science2. This class3. LIFE
29Mystery GooI 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.
30Remember: safety equipment! Name: _____________________Date: ______________________Period: _____________________Mystery GooDirections: 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!
32Back of Card What does this tool measure? Volume …in what units? Milliliters (mL)How do I use this tool?…coming up next!
33Reading the Graduated Cylinder Your eye should be level with the top of the liquidYou should read to the bottom of the MENISCUS
34Reading the Graduated Cylinder What is this reading?_____ mL
35Reading the Graduated Cylinder What is this reading?____ mL
36Reading the Graduated Cylinder What is this reading?____ __
37Reading the Graduated Cylinder What is this reading?____ __
38Expectations Always respect your environment and clean up. Be responsible and write observations as you workBe ready. Everyone in the group must participate.Follow PROCEDURE carefully…remember the “directions” exercise at the beginning of classProtect yourself and do not eat ANYTHING.Remain at your lab stations!!!
39Lab Procedure Only begin with pre-lab questions done AND checked Send one to get materialsSend one to get goggles for groupTwo clear tablesAlways think first, write own thoughts, share with group one at a time, then may choose to revise
40Homework Complete any unfinished class work Do the Scientific Method in PracticeSigned syllabus and letter home by Fri
41Daily Quiz Complete your daily quiz silently. When time is up, we will grade them.
