Moon Crater Lab - Deer Valley Unified School District

MOON CRATER LAB DO NOW SWBAT ANALYZE THE FACTORS AFFECTING THE APPEARANCE OF IMPACT CRATERS AND EJECTA Observe the two photos of the moons surface 1. How and when do you think those craters formed?

MOON CRATERS VS. EARTH METEORS!!!!!!! CRATERS The moon has no atmosphere So there is no erosion Neil Armstrongs foot print is still there today! LUNAR SURFACE fine powder above a harder surface created from ancient volcanoes and lava flows If there is no erosion how did the surface get covered in fine powder?

BACKGROUND INFORMATION GUIDE Read aloud Questions Meteor Crater, Arizona ANATOMY OF CRATERS LAB BACKGROUND/OVERVIEW Write your Purpose: The objective of this lab is to test the relationship between crater size and either the kinetic energy or the mass of an object that creates it. Vocab:

Kinetic energy= energy of motion- FASTER= more kinetic energy Rays- the lines of ejected material from a crater Diameter- the distance across a circle You have a choice in your group of 3 Choice- Change the Mass of the object or Change the Height of the object HYPOTHESIS The objective of this lab is to test the relationship between crater size and either the kinetic energy or the mass of an object that creates it. 1. Your hypothesis needs to be written as an if, then, because statement.

2. Your Independent variable is either changing the mass or height dropped 3. Your dependent variable is how it effects the diameter, depth, and length of rays for an impact crater. Sentence Starter: If the ______independent variable____ of the object is ___________,then the diameter of the impact crater will ________, the depth will ______________, and the length of the rays will ___________________ because_______________________________________. PROCEDURES

Procedures: 1. What steps would you need to take in order to test how the height (kinetic energy) effects a crater? 2.What would you need to do if you were testing how mass effects a crater? T-W-P-S Write down a rough draft of procedures as a group We will finalize them as a class. DATA TABLES Trial 1 You will need to create 3 data tables like this one

for the 3 different heights or masses you will be using Independent Variable (Height or mass) (cm or g) Depth of crater (cm) Diameter of crater (cm) Average Length of all rays (cm)

Trial 2 Trial 3 Average EXIT TICKET 1. What gives the moon its appearance? 2. Why does the moon have a fine layer of powder with solid rock underneath it? 3. What is an impact crater? 4. What is the ray of an impact crater? 5. Why do the craters of the moon never seem to

go away? 6. What is a diameter? LAB This lab will be conducted outside Teams of 3 (your tables) 2 groups will be at each bin (Demonstration of expectations) General Procedures: 1.

Perform the lab 2. Once completed, work on the discussion questions with your group in the classroom. (need to be seated) What I should see O.O 1.Students working urgently to perform the

lab 2.Sharing the bin 3.Staying in your own group What I should hear (-(o.o)-) 1.Vocabular y words, rays, diameter, impact crater
