Submarine SMASH Day Reflection



1. Summarize --

-- What did we do for SMASH Day?

In the beginning, Mrs. Smith tell us that she has a task for us. She sent us a carton, 4 mirrors, 10 peace of paper and two tapes. She wanted us using those material to build up a periscope of submarine. Our group, Chris and me, tested reflection of mirrors again and again trying to find out what is the best angles of vision. After we set up the angles, we cut the carton to pieces. We don't want to waste out our tapes, so we inserted the mirrors into the pasteboard directly. Finally we can saw the stuff above the desk by angling the two mirrors. But we waste too much pasteboard making us could not build up the box of periscope. That was sad.

-- What was your mission?

In our group, Chris and me, should test the reflection of mirrors trying to find out what is the best angles of vision. After we set up the angles, we must cut the carton to big pieces. And make up a periscope.

-- What supplies were you given?

Mrs. Smith tell us that she has a task for us. She sent us a carton, 4 mirrors, 10 peace of paper and two tapes.



2. Reflect -- Scientists often make a hypothesis, test it, and then change (or modify) their design to make it work.

-- How many times did you have to modify your design?
Many times, maybe ten times or more.

- How did you know that you should modify your design?
Because we couldn't see the stuff above the desk.

-- How did you know what to do when you modified it?
We did see the stuff above the desk.

-- How did your team communicate to decide how to modify your design?
Discuss each others ideas and action, sometimes argue.


3. Tips and Suggestions

-- If you could give a list of tips and suggestions to someone who is doing this for the first time, what would it be? What would you tell them to help them out?
1. Must test the angle of each mirror above and below again and again. Find out the best one.
2. Cut the card board carefully.
3. Fix the mirror into the box strongly.
4. After all the things are done, check all the mater you made. If it is perfect, HI FIVE ! GOOD JOB !

Phelp's iPod

Friday, Aug 15, 2008 1:32 pm EDT The mystery of Michael Phelps' iPod playlistBy Chris Chase In the long, storied history of Fourth-Place Medal's Investigative Unit (founded: Monday), one question has been asked by our readers more than any other. Today, on our five-day anniversary, we will attempt to tackle the biggest Olympic mystery of the Beijing Games: what is Michael Phelps listening to on his iPod? In nearly every camera shot of Michael Phelps on dry land, he can be seen with iPod headphones dangling from his ears. The earbuds are a ubiquitous presence in the ready room and on the starting block; they're just as much a part of Phelps' 'uniform' as goggles and a swim cap. About two minutes prior to the start of a race, Phelps sheds the iPod along with his warm-ups. So, what is he listening to? Podcasts of NPR's This American Life and Dylan live at The Supper Club. No wait, that's my iPod. Phelps listens to hip-hop music on his. He says it helps moti...
