Agenda
Roll
PowerPoint on Earth Science Models
and Measurement and Safety
3. Possible Video
You need to have your Science Notebook out on your desk and opened to page 6.

2. Subject Area: Models and Measurements
EQ: How do we appropriately collect data, and display data?
Questions:
How are models used in Earth science?
What are the limitations of models?
What is the importance of the international system of units?

3. Is the Worldwide temperature increasing?
What would happen if the temperature rose only a few degrees?
Rotting remains would increase adding
carbon dioxide to the atmosphere.
There would be more rain
due to the increase of evaporation.
Sea levels would rise flooding all
cities that are at or below 8m above
sea level.
Much of the sea ice near the poles
would melt.
One way scientists study global warming is by making models.

4. Types of Models
Models are representations of objects or systems.
1. Physical Model - Models that you can touch
2. Mathematical models - Made up of mathematical
equations and data.
3. Conceptual Model - Composed of many hypotheses
that have been tested through the Scientific Method
Partner Question:
What is the difference between a
physical model and a conceptual model?

5. Physical Model
Global Warming

6. Mathematical Model
Global Warming

7. Conceptual Model
Global Warming
Models are used to predict the future. They are good for asking
What if?

8. Temperature is in Kelvin
Measurement
It is important to use the International System of Measurements
so you can compare your data to that of other scientists.
Length is in meters
Volume is in liters
Mass is in grams
Temperature is in Kelvin
Partner Question:
Why do you need to use the international system of measurement?

9. Length
kilometer - km meters
decimeter - dm meters
centimeter - cm meters
millimeter - mm meters
Volume
liter - L - 1 liter
milliliter - mL liters

10. Mass
kilogram - kg grams
gram - g - 1 gram or kg
milligram - mg grams
Temperature
Kelvin - K - 0 degrees Celsius = 273 K
100 degrees Celsius = 373 K

11. A Closer Look at the Planets
What did I know? 1. 2. 3.
What did I learn?
What do I want to know
more about?

12. Have a Great Day! Class Work
Do workbook sections 3 and 4 in chapter one.
This is on pages 5 – 8.
Have a Great Day!

13. Review Game There will be several teams. I pick the numbers.
You will have a choice of a Fill in the Blank question that is worth 3 points or a true false question that is worth 1 point.
If you answer without help from your group you will get a bonus point.
If a team is talking then or an answer is shouted out then there will be points taken away from your team.
If the team gets the question wrong I will pull a number and that person will have the opportunity to answer the question. If they get it right then the team get the regular points if they get it wrong then the team get minus one point. This person does not have to answer the question.
The team with the most points will get three “Maverick Bucks”, second will get two, and third will get one for each member of the team.
