Description
A space ship traveling east flies directly over the head of an inertial observer who is at rest on the earth's surface. The speed of the space ship can be found from this relationship: .
The pilot fires an ion gun that propels ions from the space ship at 1.0 × 108 m/s relative to the ship. What is the speed of the ions as measured by the earth observer?
Reference: Ref 28-5

LSUS General Biology The Science of Soap Discussion
Hand washing helps to reduce the risk of bacterial infection by removing and destroying bacterial cells. Research the action of hand soap on bacteria, and describe specifically how soap interferes with the bacterial cell membrane. Discuss the proper way to wash your hands and how long you should wash your hands. Research and try to find the best hand soap to use to kill the largest amount of bacteria.

AHS Candies Reaction Project
In this Unit, we learned about different kinds of chemical reactions. You will demonstrate your understanding of these concepts by performing an experiment that focuses on chemical reactions between different substances.
Before you begin, review the concepts behind chemical reactions found in your textbook. You will be using these concepts to carry out your experiment.
First, formulate your hypothesis (Scientists pride themselves on being able to prove themselves wrong. So don’t worry if your hypothesis turns out to be incorrect!) What do you think the reactions will be between the different kinds of candies when they are placed into the different kinds of soda? Record your predictions. Remember to record a hypothesis for each separate type of candy, combined with each different type of soda.
Next, collect all the necessary items for the lab. You may already have these things around your home, or you should be able to get them easily at any store. You will need:
Mentos candies
Another type of candy
Meter stick
Magnifier
Test tube
Then, carry out the experiment. Make sure you are wearing your safety equipment, and that you are carrying out the experiment in a box or aquarium that will prevent a mess. Place each different type of candy into each different kind of soda and record the reaction that takes place. Be careful, because this may or may not cause a violent chemical reaction that could result in an overflow of soda.
Finally, you are going to compare the predictions you made in your hypothesis to the results you got when you conducted your experiment. Did the experiment go like you planned? If not, why do you think the results were different from your predictions? Why do you think the experiment turned out the way it did? Were there any additional factors that might have influenced the results of the experiment? If you did the experiment again is there anything you would have done differently?
Final Product: Lab report
Your lab report will be made up of four sections. Each section will be between two and five paragraphs. These should be labelled with individual headers: Question and Hypothesis, Experimental Process, Summary, and Analysis.
You will be graded on each section individually. You will be assessed on understanding of the scientific process, the content of your experiment, and the thoughtful development of your ideas. Notice that the Analysis section is weighted heavier than the others - the Analysis section should discuss what your your results mean, and this is the most important part of your experiment.
15% of your grade will be on grammar, mechanics, and polish. This will include spelling, punctuation, sentence structure, clarity of writing, and organization for ease of reading.
