February 16th

Hey everybody!  Today the people in 1st period who are in our group (Maybry, Elizabeth, and Gray) made a parachute and attached it to Ashley's group's container.  They tested it this morning, and then we tested it again.  It worked pretty well, and tells us a lot about how to make the actual one.  The only thing that was that the spill hole was a little bit too big.  If it was smaller, it would have slowed down even more than it already did.  We will upload the video tomorrow during class...after we edit it because it is a little bit toooo long:) We figured out that the spill hole's size is extremely important to the parachute.

We will keep you updated!

Hoping this will be epic...

There is now an Irish dance movie coming out!!! Here is the trailer:

Camera into space

Our eighth grade class is sending a camera into space! We are using a weather balloon. We have different teams working on different parts of the weather balloon and container and parachute. Zelle, Maybry, Elizabeth, Gray, and I are working on the parachute. We are planning on using Polyurethane Coated Ripstop Nylon. We are working on ordering it now. This is the type of design we are making it:

Balloon Racer

We finally got our balloon racer to work!!!  Here are the calculations...

Mass: 100 grams

Acceleration: 0.24 m/s *squared*

Total net force: 24 N

Pictures:

Zelle was not too happy with me at the moment...

I think that we built like three different cars...and I broke one!!!






Description: Our balloon racer's body was made out of styrofoam and the wheels were CD's.  To secure the wheels, there were Gatorade tops that kept them in lign.  There were wooden dowels that were the axels for the wheels.  At first, the body was made of cardboard, but it wasn't sturdy enough.  It was also too heavy.  The last thing that we did was put weights (20 grams) on the front to make sure that it went straight.
