Activity Possibilities
Posted on October 14th, 2011 at 3:52 pm by mbmcconaha42 and

I am going to put the three activities I would like to do on here so my group may comment on them.

1. Life Support Systems
The objective of this activity is to have students design and build models of lie support systems for a settlement on the moon.
~Divide the class into Groups.
These groups are based on the main objectives for a life support system on the moon. (air supply, communications, food production and delivery, electricity, temp control, recreation, waste management, transportation, and water supply)
People in each group should be given roles such as organizer, researcher, builder, recorder, artist, etc.
The groups will be given an ABC fact sheet about their main subject on the moon and must be able to compare and contrast to what we already have on earth to see what will work the best.

2. Differentiation

The Objective is to see how minerals separate from each other in a magma ocean.

Background-When planets begin to melt the materials separate.  The heaviest such as metallic iron sink to the bottom.  Low Density magma rise to the top to form the crust.  This happened on the moon and there is information on the activity sheet that talks about this more in depth.

~Materials and Procedure

We need water in a transparent container, sand, pennies and  toothpicks.

Take a hand full of pennies, sand and toothpicks and dump them into the water.  The pennies (heavier density/moon core) sink faster than the sand.  The toothpick float at different angles at the top (represet feldspar on the moon that formed its initial crust).  The water in between represents still-molten magma.
