WELCOME TO:MRS. HARRIS’ SCIENCE
CLASS
Find your seat by looking at the name on the student information sheet. Then
begin filling out your student information sheet.
You may put your kleenexes/paper towels and hand sanitizer in the back of
my room.
Good morning
If you have not filled out your Section 2 Table of Contents,
do so now
SCIENCE JOURNAL
I. Section 1 – Notes
A. Notes will be taken & tests will primarily come from the notes
B. Table of Contents will be filled out before taking notes
C. Each entry on notebook paper must have a date & Page #
II. SECTION 2 - papers
A. All the papers from the unit will be given to you ahead of time.
B. Each page should be # and dated
C. Each entry in the table of contents needs to be labeled, #, and dated
D. ALL PAPERS NEED TO BE KEPT UNTIL THE END OF A 9 WEEKS –
E. Journal will be graded as a test grade
III. Section 3 – Flashback (BEST) questions/ Probe activities
A. Flashback (BEST) questions – on Post-Test 1. 1 or 2 questions completed at the beginning of each class period; Questions will be from previous content or will work on college- readiness skills of data & graph interpretion 2. Each question worth 2 pts. – graded by shoulder partner & turned in at the end of 9 wk for a grade from shoulder partner
B. Probe Activities – thinking activities prior to a lesson; usually work with shoulder partners
SCIENCE BASICS
A. Science – “scire” = to know
B. Science – knowledge obtained & tested through the scientific method
1. known facts
2. always changing
3. answers questions
4. can be applied to life
C. Areas- “ology”: study of
-------- Science --------
Ex. Biology, zoology, meteorology, geology, cytology, physiology, paleontology, astronomy, herpetology
D. Observation – use all senses;
- sight
- smell
- taste
- hearing
- touch
1. Qualitatative – descriptions – ex. Round, blue, soft, etc.
2. Quantitative – numbers,
measurements; gathering data
ex. 25 ml, 50 cm, 37oC, 5 N
SCIENTIFIC METHOD -
II. Scientific Method – (SHEC)A. State the Problem/Gather Information
State problem (ask question)
B. Hypothesis – educated, testable guess
Hypothesis
C. Experiment – test/analyze data
1. control – do nothing to; used for comparison
2. test 1 variable – thing you test –
try to test 1 thing at a time
a. independent variable – variable being changed; ex. giving a headache medicine; fertilizer put tomatoes;
x-axis (on the bottom)
b. dependent variable – observed result of the independent variable being changed; ex. time it takes for headache to be gone; size of tomatoes;
y- axis (on the side)
3. repeat many times/use large #s
ex. test 20 times; use thousands of subjects
Design and Conduct an Experiment
Analyze the Results of an Experiment
D. Conclusions are drawn
- Is circular
State problem
Hypothesis
Conclusions
Experiment
Conclusions
III. Tools/MeasurementsA. meter stick/ruler: measures length –
units: m or cm
area = l x w
B. thermometer: temperature – oC or K
1. Kelvin = oC + 273 or Celsius = K- 273
2. Absolute Zero (0 K) = all molecular movement stops
ex. 10 C + 273 = 283 K
C. balance: measures mass – units: grams
1. mass – amt. of substance
2. weight - force of gravity on mass
Mass and Weight
D. graduated cylinder, beaker or ruler: measures volume – unit: l, ml or cm3
1 ml = 1 cm3
volume determined by:
1. looking at volume (@ bottom of meniscus or dip)
2. displacement (or bathtub) method – how much volume moves up
3. V = l x w x h (use ruler – cm3)
E. balance/grad. Cyl. (or ruler) = finds density: mass/volume – units:
g/ml or g/cm3
ex. 5 grams
2.5 ml = 2 g/ml
ex. 10 grams
20 cm3 = .5 g/cm3
F. spring scale – measures force/weight: units newtons (n)
G. barometer – measures air pressure – units mm or atm
H. Microscope – views small items
