Asteroid Lab - 2/2 to 2/9

Post date: Jan 28, 2016 6:57:47 PM

Big Question

What properties of a meteor make for the deepest impact craters?

Properties tested in class

Size

Mass

Speed

Density (all groups test)

Measured

Depth

Words to know:

Warm-ups

2/2 Classroom Review:

- Independent Variable
- Dependent Variable
- Constant
- Trend
- Correlation

What should you do in the first 5 to 10 minutes of class?
Where do you put your warm-up? What goes into a warm-up?
Where are the turn-in bins?
Where are the handout and assignment bins?

Asteroid Lab

Part 1 - Propose a Hypothesis and Design an Investigation

Background

Hypothesis

Variables

Materials

Experimental Procedures

2/3 Inquiry question: Does greater [mass, speed, size] of a meteor cause a deeper impact crater?

Part 2 - Analyze and Communicate Data

Data Collection

Graphs

Data Analysis and Conclusions

Make a hypothesis to the above question with your groups chosen independent variable.
Make a set of step-by-step procedures to test your hypothesis. Provided materials:

coffee can of flour
6 spherical objects
meter stick
straw
spoon

2/5 For our question:

How will you make a graph of depth versus independent variable?
How will you know if the data supports your hypothesis?

2/8 For the depth vs. density scatter-plot graph, how will you know if the data supports the prediction: "The greater the density of the meteor, the deeper the impact crater?"
