HEAT SHIELD

Today Lena, Maya and I expieremented with heat shields, we didn't have that much time so we just made one. At first, our goal was to have it last for 1 minute, but then it acually lasted for 5 minutes, and would have lasted longer if bert hadn't turned the heat off. So, I really liked this is was very entertaining, and I don't have any questions.

Motors

Today Maya, Alice and I expieremented with motors. We rapped wire around a a straw, and then we took it off to create a wire circle. Then we tapped 2 paperclips to the side of the batter, and on the belly of the battery, we tapped a magnent. Once we did that, we attatched the wire circle to the paperclips, the magnetic energy between the wire and the battery was supposed to spin the circle around and around. It didn't work so great, instead the circle would just move a little bit.

Magnets and a Ruler

Today Lilly, Tmike, and I learned and worked with marbles and magnets. It was interesting to see how strong magnets can really be! We wasted a lot of time trying to get the magnets apart, and then they would get back together and it kept happening. Anyways, we made a magnetic rifle. The base was a ruler, it layed flat on the table and the we taped a square REALLY strong magnet every 3 inches on the ruler. Inbetween each magnet, we put 2 marbles. Then, we would launch a marble towards the first magnet and it would cause a chain, then the last marble would launch and roll far away. This was the coolest lab so far!

Sound Measurments Lab

Today Emily and I focused on magnetic energy. We used the computer to track how much energy there is in a nail and battery. It was confusing because I didn't really understand the instructions, so we kept asking questions and then we ran out of time. If we had to do this again, I think it would be better if we had more time.

Impact Craters

Yesterday in Class, Lena, Lehayhay and I expierimented. We had a tray on flour. The flour was approximatly 1 inch deep. At first we dropped a ping pong ball about 10 inches above the flour. Then we continued doing this with different mesasurments. We noticed a trend: The higher you drop the ping pong ball from, the bigger impact. This related to when we learned about GPE and KE.

Mini Culmination Prep.

Today I tested our parachute a gazillion to see if our robot arm and the parachute were compatable. They were! I'm happy with our accomplishment. Today was also fun because Gemma and I practiced our communication using skype, and we're getting a hand on it. I'm a little frazzeld because the rover needs some help, from what I've heard. I think we can pull it together this time, and it feels good.

Mini Culmination Prep.

Today Gemma and I worked on our communication skills. I had a built lego project, and she had peices lego peices. I had to tell her how to put the peices together to attain the same object as me. It was hard because she didn't have some of the parts she needed to create the same object. It was fun to explore Skype, and how it works. I also helped Maya with the robot, and Meena with her basket. It was fun, and I hope our group is coming along the way it seems to be.
