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.

ASSIGNMENT:

 Create a poster that visually details the ROUTE OF ADMINISTRATION of a specific drug as it is ABSORBED, METABOLIZED and EXCRETED by the human body.

 In the presentation discuss the progress of the drug from administration to excretion in a step-by-step way.

 In other words, chart the progress of a specific drug from its point of entry into the body as it moves through the various organs, tissues, and structures of the body until the drug, or its metabolites are excreted. For example, if your assignment was on the intravenous use of heroin, the poster should include a drawing, diagram, or photograph of a syringe; of heroin itself; of a needle puncturing a vein; of heroin travelling through the circulatory system to the various organs, and so on.

In both the poster and the presentation, be sure to specify:

• the route of administration (a.k.a. how the drug got in the body)
• the drug itself.
• how the drug gets from the point of entry into the circulatory system (if applicable)
• what happens next (Where does it go? How does it get there?)
• the organs and tissues involved in breaking the drug down
• how/where the body excrete the drug or it’s metabolites.
