SCIENCE 10 – Intro                                   Sept. 7

What is science?   (fire demo)

Uses a method for writing an explanation or theory for how things work.

This theory has agreed upon steps:

1. Purpose or problem (a question)

2. Come up with a guess how to test your question.

(Hypothesis)

3. Design an experiment

- equipment

- procedure (directions or steps)

- sketch

- observations

- data

4. Answer the question by concluding something.

(5).  Communicate your findings, revise the problem. 

Assignment 1

Make up your own problem, hypothesis, experiment and conclusion.  Follow the requirements in the notes.

One page maximum!

· Put a title, date and name on it

· If testing two things, make the conditions all equal except the product you are testing (CONTROLLED).

SCIENTIFIC METHOD

Examples:

1. What is the gas in a balloon?

2. Which toothpaste prevents more cavities?

3. Does listening to music affect learning?

  Make sure you use “controlled” conditions!

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

UNIT I. APPLICATIONS OF SCIENCE

I. SAFETY                              

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

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

2. Safety Equipment : photos of equipment, lab tour

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

3.    Safety Symbols

4.    (Safety video?)

II. MEASUREMENT                           

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 = measure of degree of detail that can be measured reliably

Reliability = how reproducible experiment is

Accuracy = measure of how closely experimental results agree with a

                   true or accepted value, quality or correctness of result

*can be precise without being accurate… equipment or operator error

* scientists want to be both precise & accurate

* Quiz

2. Communication
