1. Observation vs Inference

2. In your notes…. Write down what you think an observation is.
Write down what you think an inference is.
Discuss it with your partner.
Now use your phones to look up the definition to these words.
Based on the definitions that you found, walk around the room and make ten observations, and ten inferences.
Have your partner check your work and see if they would change anything you wrote down.

3. Vocabulary
Observation: Something you can see, touch, taste, smell, or hear. Information you gather from your five senses.
Inference: A conclusion reached on the basis of evidence and back ground knowledge. You use your observations to make an inference.

4. What Observations can we make from this picture?

5. What inferences can we make?

6. Looking at verdi….
What are some observations you can make about Verdi or his habitat?
What are some inferences you can make about Verdi?

7. Let’s Practice!!
In your table groups work together to complete the boy in the water worksheet.
If you have questions please ask!
When your table is done raise your hand and I will come over and check your work.
After your worksheet has a stamp this needs to be put in your three ring binder. This will be your first paper in the assignment section.

8. Remember you have to stay in your assigned seat!

9. The Metric System

10. Why the metric system?
Used by most other countries for normal measurements
Used by scientists all over the world!

11. Different parts of the metric System

12. Length A measure of distance Base unit is the meter
Measured with a ruler or meter stick

13. Mass The amount of matter something is made of Base unit is the gram
Measured with a balance

14. Volume Measure of how much space something takes up
Base unit is liters
Measured with Graduated Cylinders, pipets, beakers, flasks, burets, etc.

15. Temperature Measure of amount of energy in an object
Measured in degrees Celsius (or sometimes Kelvin)
Measured with a thermometer

16. A metric cheat sheet
Copy and fill in the following chart to help you remember the different parts of the metric system

17. Using the Metric System to Convert.
Prefixes
Kilo – k, 1000
Hecto – h, 100
Deka – da, 10
Base Unit – (Liter, Meter, Gram)
Deci – d, 0.1
Centi – c, 0.01
Milli – m, 0.001

18. An Acronym to help King Henry Dances Merrily During Cold Months Kilo
Hecto
Deka
Meter/Liter/Gram
Deci
Centi
Milli
King
Henry
Dances
Merrily
During
Cold
Months

19. Putting Prefixes and Bases together…
a) Centi + meter = Centimeter
b) Kilo + liter = Kiloliter
c) Deka + gram = Dekagram

20. Metric Conversions
Since metrics are based the on the power of 10 each “step” is either:
10 times larger or times smaller
Kilo
1000
Hecto
100
Deka 10
Base
Deci .1
Centi
.01
Milli
.001

21. For example, centimeters are larger than millimeters so it takes more millimeters to equal the same length in centimeters. 40 41
1 mm 40 41
1 cm

22. (so you move the decimal 2 times to the right)
An easy way to move within the metric system is by moving the decimal point one place for each “step” desired.
Example: change liters to centiliters
1 liter = 10 deciliters = 100 centiliters
(so you move the decimal 2 times to the right)
kilo
hecto
deka
meter
liter
gram
deci
centi
milli

23. (so you move the decimal 3 times to the left)
Now let’s try the second example this time moving the decimal to the left.
Example: change grams to kilograms
2 grams = 0.2 dekagrams = 0.02 hectograms = kilograms
(so you move the decimal 3 times to the left)
kilo
hecto
deka
meter
liter
gram
deci
centi
milli

24. 4 Now let’s try another one.
Example: change centimeters to kilometers.
400,000 centimeters = __________ kilometers 4
kilo
hecto
deka
meter
liter
gram
deci
centi
milli

25. Metric Summary
Base units in the metric system are the meter, liter, gram
Prefixes can be used with many of the base units
The Metric system is based on the power of 10
For conversions within the metric system, each “step” is 1 decimal place to the right or left
kilo
hecto
deka
meter
liter
gram
deci
centi
milli

26. Let’s Practice a few with the whiteboards.
Send one person from your table to get whiteboards, markers, and erasers for everyone on the table.

27. Practice assignment
You have until 5 minutes before the bell rings to work on this assignment. What ever you don’t get done is homework.
