Ice Breaker!1. Partner up with someone at your table.

2. Decide who will be describing and who will be drawing.

3. I will come around and give each describer an index card with a picture on it.

4. Don’t show your partner or tell them what is on the card!!!

5. Wait for my instructions.

Safety Contract•Read and take home to be signed.

•You can’t participate in lab without this!

Scavenger Hunt

•Turn them in up front when you’re done

Notes: The Metric System

• Based on powers of 10• So every step up or down the scale is ten times bigger or smaller than the one before it

***exception to the rule: after 103 or 10-3 the

exponents start moving by 3’s so they are 1000 times bigger or smaller than the one

before it – not 10 times.

Notes: The Metric System

Let’s try some examples

Academic Homework• Buy supplies for class – binder/dividers/pencils (colored

pencils & highlighters)

• Finish metric riddle – You must show work to receive credit

• Get safety contract signed

Notes: Temperature Scales

• Temperature is a way to measure the average kinetic energy of the particles in a sample of matter

Temperature reading on the thermometer• There are 3 scales that we use:

1. Fahrenheit ◦F

2. Celsius ◦C3. Kelvin K - no degree symbol

Notes: Temperature Scales

Notes: Temperature Scales

◦F = 1.8 ◦C + 32 OR ◦C = (◦F - 32) ÷ 1.8

K = ◦C + 273 OR ◦C = K - 273

K = [(◦F - 32) ÷ 1.8] + 273 OR ◦F = 1.8(K-273) + 32

Let’s look at 3

examples

Scientific Notation

Notes: Scientific Notation

N x 10nA number between 1

and 10 (usually a decimal)

A whole number (+ or -)+ means bigger number- means smaller number

Scientific notation is a shorter way to write a really really big, or really really small number. A number written in scientific notation has the same value as the longer number, it’s just written differently. It’s like writing your initials instead of your full name. Your initials still mean your name, they’re just written differently.

3.45 x 109 L is the same as…3,450,000,000 three billion, four hundred

6.7 x 106 m is the same as…6,700,000 six million, seven hundred

thousand OR 6.7 Megameters
