Lab Objectives
In this lab you will:
help the aliens, called Tinyians, build the best house on their planet called Tiny World.
experiment with different building materials to collect data to see which ones best meet the criteria for building a home on Tiny World.
test each building material for density, thermal and electrical conductivity, flexibility, and magnetism.
Background Research:
You will need to gather background research from the virtual lab to form a good hypothesis. Read the Welcome to Tiny World part of the lab. Use the background information you learn to answer the questions below.
Describe the gravity of Tiny World.
Describe the reason your house will need magnets.
Describe the climate of Tiny World.
Hypothesis:
In this section, include the IF/THEN statements you developed during your lab activity. These statements reflect your predicted outcomes for the experiment.
A
If we use _______ to build the roof of the house, then the temperature inside the house will remain cooler.
B
If we use_______ to build the walls and floors of the house, then the temperature inside the house will remain cooler.
C
If we use ______ to bring electricity into the home, then it will allow electricity to flow into the home at a faster rate.
D
If we use_______ to construct the latches on the windows and doors, then the magnetism will keep the latches secure.
Procedure:
You will test each building material for density, thermal and electrical conductivity, flexibility, and magnetism.
Record your observations in the data table provided below.
Repeat steps with all test materials.

D.
5
Why do you think a building material's density is important when building homes or architectural structures?
6
Why wouldn’t you choose wood or aluminum for the latches on your house?
7
Which material has the highest thermal conductivity?
8
Which material has the highest electrical conductivity
9
Based on your data, explain why these materials have the highest thermal and electrical conductivity?
10
Think about where you live now or where you have lived in the past; use complete sentences to describe this environment and the weather.
11
What building materials do you believe would work best to build a home in your area? Explain why you chose these materials.
