  1. Homeroom Sit where you sat yesterday and grab a book! Begin reading silently! Remember, reading silently earns you class points!

  2. Do Now Copy the following Frayer Models into your notes. I’ll provide the definition, and you have to figure out the rest! Observation used to describe what we see Definition Definition Characteristics Characteristics Observation that measures what we observe Qualitative Observation Quantitative Observation Examples Examples Non-examples Non-examples

  3. Announcements • All classroom materials need to be with you by this Friday! • Homework Packets due on Friday • If you have problems getting the materials, talk to me about it during independent work • Scientific Method test September 5th

  4. Agenda • Do now procedures • Scientific Method overview • Pediculus Humanus Capitus • Quick Q and A about rules/agenda • Classroom procedures: • Entering class • Paper headings • Assignments • Garbage

  5. Why relearn scientific method? • In this class, you and your group members will be designing your own experiments quarterly that relates to our content. In order for this to occur, you’ll need to follow the steps of the scientific method.

  6. Qualitative Observations • Qualitative observations describe what we observe. • “Qualitative” = quality (descriptive) • These observations use adjectives to describe something. Example:The flower has white petals. Example:Ms. Lloyd has brown eyes.

  7. Quantitative Observations • Quantitative observations measure what we observe. • “Quantitative” = quantity (numerical) • These observations use numbers to measure something in a quantitative way. Example:The flower has seven petals. Example:Ms. Lloyd has two eyes.

  8. Application of the scientific method • Friend sent me a package on Thursday • Dr. Thomas Heavey: PhD from CalTech in BioChemistry • Found during an excavation in Los Angeles in the sewers • Pediculus humanus capitus • AKA: Head Lice

  9. What he found • Genetically mutated lice • 100 times larger than normal • No longer parasitic • Actually purify the sewer water so that we can drink it • Can’t walk, only can swim • Would you like to see them? • You need to QUICKLY write a scientific question that you’d like to ask Dr. Heavey.

  10. Examples: • Does the size of the head lice affect its inability to walk? • If the lice continue to thrive inside the sewer, will they continue to mutate?

  11. As I’m walking around… • I know this is exciting, but we CANNOT SCREAM! • You need to write down TWO QUANTITATIVE observations and THREE QUALITATIVE observations!

  12. Benefits • Not only do they purify the water, but they are also edible. • They could help end hunger, while cleaning up our water and helping to eliminate water pollution

  13. What’s really happening? • It’s actually 7 Up, raisins, dirt, and leaves • What’s happening? • Wrinkles and convolutions on the raisins catch the carbon dioxide bubbles. • When enough bubbles have collected on the surface, they “swim” to the top.

  14. What has this taught us about observations? • Both types of observations are good in science. • But quantitative is more testable Qualitative:The road is long. (describes) Quantitative:The road is 5 km long. (measures) • Some things are easier to quantify than others. Scientists use innovative ways of turning qualitative into quantitative.

  15. Quick Q and A • Why is it important that we follow the class rules? • Which to you is the most important rule that we need to follow? • Why?

  16. Entering Class • A lot like the Do Now • Make sure your materials are out. • Bags are under your chair if possible • Any problems you have, stay outside the door

  17. Paper Headings • First line: First and Last name • Second Line: Date • On anything you turn in!

  18. Homework Assignments • Paper heading must include your name on the first line and the date on the second. • Graded for completion unless otherwise stated. • Late assignments are taken, but with a point deducted for every day. • Maximum deduction of 4 pts.

  19. Garbage • DO NOT turn my classroom INTO A BASKETBALL GAME, unless you are actually a GOOD shot! • Garbage is not to be shot into the garbage. • If you choose to do so and miss, you will be doing 10 push ups for every shot. • No, I do not care if you eventually make the shot!
