How to put a heading on your papers?CBM Name: C002 (Microscope CBM) #523 Olive Skool 31 Aug 2011 5th Hour Switzer
Test Tips: • Read the question, think of an answer before selecting a choice. • Read all answers carefully • Eliminate answers you KNOW are wrong • Go with your first “gut feeling” • Skip a question if you’re stuck, and return to it later • Double check your answers when you’re finished • Mark an answer for every question • If you have no idea, then choose the longest answer, or letter C
Do Now: • Copy the content and language objectives • Answer in complete sentences: • Write a hypothesis for the following questions: Which has bigger cells, a human or an onion? • What do you know that is one foot long? One centimeter? When you finish, read the objectives on your “What is Life Science” packet. *Reminder: Progress Reports due today.
Opening • Measure the width of your desk. How many hands does it take?
Measurement • Why should the U.S. change to the metric system? Or not?
Measurement The Mars Climate Orbiter (MCO) In one of the all time great engineering mistakes, NASA’s partner, Lockheed Martin, used English Standard units, not the metric units used by NASA. The probe eventually hit the Martian atmosphere at the wrong angle and burned up.
Friday Do Now: • Copy the content and language objectives • Write your answers in complete sentences • What measuring system do scientists use when they communicate with each other? • When scientists want to talk about a certain species, how many names do they use? • What is the scientific name for humans? When you finish, get out your Cornell Notes.

Measurement Tools Name: Triple Beam Balance Measurement: Determine the mass Units: grams (g)
*Important Reminder! • A triple beam balance has three separate lines (it’s like adding three rulers together)-you must ADD each of the lines together!
Scientific Names I. Scientific names are given to species so that all scientists can communicate. a. It has two words: a genus name and a species name b. The first letter of the genus name is capitalized, and the species is lowercase. c. If you’re typing, you write the scientific name in italics d. Your scientific name is Homo sapiens.

7th Hour • Background: (copy this) • Foxtail barley: Hordeumjubatum • Indian Sweetclover: Melilotusindicus • You calculate an average by taking the sum of all measurements divided by the total number of measurements. • The larger a sample size, the more reliable the prediction • Question: Which is taller? (Hordeumjubatum or Melilotusindicus) • Hypothesis: I think Hordeumjubatum is taller because clover is usually small. • Constants: Time of day and year, group of people measuring, air temperature, humidity, weather
7th Hour • Constants: Time of day and year, group of people measuring, air temperature, humidity, weather • Materials: Clipboards/books, lab groups, metric rulers/meter sticks, lab handout, calculators, pencils • Procedure: Find 5 examples of your plants. Measure the plant height. One person will measure, and the other will write data. Calculate the average for your data. Make a bar graph of the averages
Data: • Table 1: plant heights
