Powder Lab

1. Scientist use methods like heating, adding acids, looking at closely, and adding other substances to the powders. Using these can help you identify the mystery powder that the murderer may have left behind.

2. This is useful in preparing for our mission because if the criminal has only left behind a mystery powder and we need to match it. Doing this lab has taught us how to do that incase that is the only thing left.

Trajectory Lab

Guiding Questions

1. Using the information found from a bullet hole in a wall you can tell where the bullet was shot from which can help you know how tall the murderer was. Knowing how tall the murderer was can help you find the person and gives you more evidence to find the correct suspects. 

2. This lab can help us find the person who committed the crime and helps us get a better understanding of how we might find the murderer if we only have a blood splatter or a bullet hole in the wall. 

Urine Analysis Lab

Post Lab Questions:

1. Sample A does look a lot, and smell a lot like sample C. This leads Dayton and me to believe that the person who peed in the cellar was suspect C. When we spun our vials nothing changed so we can tell by only looking and smelling them. When we boiled the urine we found that suspect 1 (in vial B) had glucose in it's urine so the pee from the cellar and the pee from suspect 2 match.

2. Yes it can because if you identify whose urine it was you can know who was at the scene of the crime. Just like this lab we figured out that it was suspect 2. 

Fiber Power Lab Analysis part 2 and 3

2. Looking at the fiber through the microscope it looks like the fiber is rayon. That means that it is Ted that has the coat that matches the murderer. 

3. From burning the suspects fiber we could tell that it burned the same way that the rayon did, it didn't burst into flames but instead it had a low glow like before when we burnt the rayon. This helped us make our final decision that Ted was the murderer. 

Fiber Power Lab Analysis

Post Lab Questions: 

1. This differences are that the natural fibers all seem to have a woven look. The all have holes in them that as unvarying in there spots. The man made fibers look like they are ether really consistent with the pattern with small holes (silk) or they are not consistent at all and have holes in different places all the time. 

Communication Lab (We'll make you talk) 2

Annabella and I did our two final parts of the lab. The first one we had to build a thing out of pieces and tell the other person how to build it just using text. It worked surprisingly well and we only made on small mistake. The second one we had to tell the other person how to find an item but we could not use certain words. We found that this one was really easy. We thought this one was the easiest of them all.  We still think that the hardest part of the lab was the one where we had to tell the other person how to open the lock. This lab had helped us know how to communicate better with only certain ways available. 

Communication Lab with iChat

We didn't get to finish the whole lab but got through two and a half challenges.

1) so far the easiest one for us to do was the video with sound where Annabella had to tell me what to draw. Our pictures ended up looking a lot alike. 

2) the hardest one was with the lock when I had to explain how to solve the lock. It was hard because I had to tell how to turn the lock and how to land on the right number. It was more challenging than the first because we had no sound!

3) If we were going to a space station it would be important for us to learn all of these ways of communication. I would hope that we would have a way to talk and here each other and see each other like in our first challenge.
