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
