YOLO PROJECT
THE HUMAN BRAIN:
The human brain is a soft organ that is surrounded by spinal fluid and protected by your hard skull. The spinal fluid around your brain is supposed to act like a cushion for your brain to keep your brain from banging against your skull. The human brain is the most important thing in your body because your brain controls everything in your body and if you don't take care of it properly then you could end up with serious injuries or even death. The human brain is divided into several different lobes. The Parietal Lobe is divided into two parts. The purpose of the Parietal Lobe is spatial awareness and perception. The Occipital Lobe is primarily function is processing, integration, interpretation ect. of vision and visual stimuli. The Cerebellum contributes to coordination, precision, and accurate timing. The Temporal Lobe plays an integral role in the following functions hearing, information, retrieval, organization. The Frontal Lobes purpose is decision making, problem solving, control of behaviors, consciousness, and emotions. The Cerebrum is the largest part of the human brain. In an event of a concussion the certain parts of the brain are going to be affected.
CONCUSSIONS:
A concussion is a minor traumatic brain injury that can affect how the brain works for a while. A concussion can happen if your head or your body is hit by a moving object, during impact your brain can crash into your skull and be injured. There are many ways you could get a concussion. Some ways you could get a concussion are from falls, playground injuries, car crashes, and bike accidents.
HOW HELMETS WORK TO PREVENT INJURIES:
LONGBOARDING WITHOUT A HELMET AND THE CONSISTENCIES:
A study shows that every year about 68,100 children ages 5 to 19 years old visit the emergency room for skateboarding related injuries. Longboarders are at greater risk of head fractures, traumatic brain injuries and bleeding inside the skull than skateboarders. The studies that I read said that "Longboarders may be at greater risk for serve injuries than those who use regular skateboarders. Among longboarders, 8 percent had a head fracture, 31 percent had a traumatic brain injury. Among skateboarders, 0.5 percent had a head fracture, 12 percent had a traumatic brain injury." People who use longboards will most likely not use a helmet because they the are on the open road and feel they are more free without a helmet. Longboarders are traveling at a higher speed than someone on a skateboard, because longboarders are on the open roads and using a down hill to gain speed rather than a skateboarder in a skate park.
THE BOTTLE ROCKET PROJECT
Introduction:
In this project my partner and I had two rockets and my rocket was called Sky Hawk. My rocket had three fins with a cone and my partner Kira had three fins and no cone. We wanted to test how does the length of the cone affect the launch of the rocket and the distance traveled. My hypothesis was that a longer cone would do the best out of the other rocket cones. For my design rocket I used 3-1 liter bottles, 1 Foam ball, 1 Foam cardboard to cut, 1 tennis ball, trash bag, rubber cement, hot glue gun, silicone glue, duct tape, and a hole puncher. We peeled and cleaned the labels off all bottles.

We peeled and cleaned the labels off all bottles.
- We cut the top off two bottles and left the second bottle uncut. and then cut the foam ball and tennis ball in half.
- Glued with hot glue, half tennis ball on top of one of the cut of bottoms.
- Glued with hot glue, from the inside the half foam ball to the top of the other cut bottle. This will be the top of the rocket and will hold the parachute.
- Then we found out that hot glue melts the bottle so we started using the silicone glue.
- With the uncut bottle we will call the body of the rocket and one cut bottles we then add them together. You can trim the one with the tennis back until it fits snugly body of the rocket.
- Then we cut out our fins out of foam board, cut the fins all the same size and then duct taped them down to the body of the rocket so that they could be very sturdy.
- We glued the body of the rocket and the piece with the tennis ball bottle with rubber glue so that they will stay together and stay sturdy. Making sure to keep it smooth and straight. the lines drawn on the bottle were to help keep the bottles in line.
- We made the parachute out of a trash bag and then got some kite string and tied it to each end and the tied them all together to a rubber band that is tied to the top of the top of the rocket.
- We decided to duck tape the top of the rocket which is the because the foam ball kept moving and so the duct tape is on the outside of the top of the rocket.
- We stuffed the parachute in the top of the rocket and placed the top of rocket on the body of the rocket, but not too tight so the parachute can be released in flight.
Procedure:
When testing the three different cones we used the same rocket, Sky Hawk. We launched the rocket three times. We only changed the cone, we did not change the fins or the pressure of the bike pump for the first two tests. With the first two tests we measured from 16 meters. When we tested the third cone we used the CO2 canister instead of the bike pump and measured from 16 meters. A variable that could not be controlled was the weather such as the wind. In each launch the parachute did not release. With each test the fins were slightly damaged which may be the reason the rocket was not flying straight.

Data:
I got my data by asking my partner to stand at the 16 meters mark and get the angle of elevation for me while I pulled the string and I also asked if someone could time for me. For each test I put on three different cones with different lengths so I could test my question that I had. After I got all my data I had a teacher help me get all of my data calculations so that I could graph all of my test results. I chose to only use the cone lengths and how high the rocket went with that one cone length to put on my graph. So I went small cone to medium cone to large cone on my graph to see which cone length would let the bottle rocket to travel the highest out of all three cones.

Conclusion:
We worked hard on our rocket, both testing and design. We had a little things that we struggled on. It was confusing at sometimes like getting the height of the rocket by using a formula to solve the height and knowing how to measure the angle of elevation. I think we mostly had a little trouble with the parachute because the parachute would never come out and we tried everything like not putting it on so tight or putting powder on it so it would be slippery and the parachute would come out but it never worked out. If we had more time to work on our rocket we would be more focus on the parachute so that when it launched the parachute would deploy and so that it wouldn't smack the ground and break the cone when it started to come down. One thing that I would suggest for future students doing this project is that the longer the rocket is the higher it goes and also to make sure that your fins for your rocket are even and sturdy or else the rocket will shot off to the side and not straight. But other than that I thought this was a good project and it was much easier the the mousetrap race car project.
