UNIT I. APPLICATIONS OF SCIENCE Feb 14

I. SAFETY                              

1. Unsafe Activities : role play, summary (activity,result)

2. Safety Equipment : photos of equipment, lab tour

Exits, Fire extinguisher, eyewash, shower, fumehood, eyeware, first-aid kit

3.    Safety Symbols

4.    (Safety video?)

SAFETY RULES

Class/Lab Rules

1.  No food in lab, wash your hands, be clean!

2.  Use proper safety equipment: goggles, fire extinguisher, eyewash, first-aid, shower, fume hood

3. Chemicals- read labels, be careful, dispose of properly,

4. Be familiar with science procedures – Bunsen burner, pouring  properly

5. Listen to the teacher, ask questions, report accidents

II. MEASUREMENT                            Feb. 15

1.  Metric System Conversions : prefixes, diagram, practice

Examples:

a. 0.45 kg  = 450 g

b. 185 cm  = 1.85 m

c.    357 μl   = 0.357 ml

d. 725 ng  = 0.000725 mg

e.    445 m   = 0.445 km

f.   27 dl      = 2.7 L

2. Measurement Lab: stations, table to fill in, discussion

Calculations:

volume of box in cm³ = ml = length x width x height

volume of a cylinder in cm³ = ml = radius squared x pi (π) x height

density in g/mL =  mass/volume

Experimental Data:

Precision = how accurate it measures,  the detail that can be measured

                   A balance that measures to 0.01 of a gram is more precise than a scale that measures to the nearest kg.

Accuracy = how well the equipment measures or works, errors can affect this

The measurement was inaccurate because the student read it wrong, or the balance wasn’t working properly.

* Quiz

III. SCIENTIFIC METHOD

Controlled Experiment

1.  Start with a question ( PURPOSE or PROBLEM):

Does listening to music help you concentrate better?

2.  HYPOTHESIS (guess):

-music will have an effect

-music will not have an effect

3.  EXPERIMENT

- A designed plan to measure and test the hypothesis

- In a controlled experiment, two groups are set up,

  Keep all factors the same except for one (variables).

  Measure the differences in the two groups.

Memorize 5 words without music = control group

   Memorize 5 words with music = experimental group

   Keeping all other factors the same: time, motion, temperature, difficulty of words, length of words

Discovery Lab: PSL with temp. probes
