Sandstone... Ocean, Beach, or Dessert?

Okay, we have a mystery: the Supai Sandstone and the Coconino Sandstone both are made of sand. But we had three different suggestions about where the sand came from.

1. A Beach
2. A Dessert
3. A Strem or River on a mountain

So which is it? Where did the sand from the Supai Sandstone (the red sand stone) and the Coconino Sandston (the tan sandstone) come from?

Today you will examine different kinds of sand in a virtual sand lab to see if you can find a way to answer that question!

To do:

Prepare Science Notebook

• Start a new page. 
• Title it "Sand Types" and put today's date (6/15/2012)
• Add this to your table of contents

Go to the FossWeb website:

• FossWEB
• UID: mrmac
• PWD: room116

Go to the Geology Lab Room

• Select SAND TYPES
• Select COMPARE
• There are three "types" of sand: river (mountain), dune (dessert) and beach (ocean)
• Compare the different sand types.
• In your science notebook, record your comparisons using VENN DIAGRAMS.
• Once you have examined all of the samples and you are satisfied that your observations are complete and accurate, go on to the next part.

Patterns!

• Examine your comparisons. Look for patterns for each TYPE of sand that would help you identify it.
• For each type of sand (dune, mountain, beach): write about the pattern you notice that describes that kind of sand.

Self Check?

• Go back to the lab.
• Select TEST YOURSELF and see how well you do!
• Record how well you do in your science notebook.
• Quiz!
• When you finish that, try the quiz otu and record how you did!
