Project Reflection:
For this project we chose our own idea and made a project around it so me and my group chose to do "Does lighting make a difference in sound waves?"

Design it clean:
What we did for this project was we decided to do Kenya, The pollutants that we were trying to filter out was mostly ecoli, and the water is very cloudy. We chose to design our filter the way we did because the first filter we made needed more pressure because the water would barely go through the filter, also our final filter still needed more pressure. .

Why you should wear a helmet
You should wear a helmet while being outdoors when riding bikes so you can protect your brain. Wearing a helmet can help prevent from getting a concussion. Look for bright colored helmets. Helmets help protect your head because it is kind of made like your head its like another skull on your skull. so you would hit your helmet instead of your head. If you were to fly forward off your bike then you would rotate forward and hit your helmet. http://www.rush.edu/health-wellness/discover-health/helmet-safety-keep-lid-it The best protection is a good helmet. the right helmet can protect your brain .We had a presenter come to our classroom to tell us about her trauma from a brain injury she said that if she hadn't wore a helmet that day she was out for a bike ride she could have died but instead she injured her memory part of her brain. Study proves that expensive and cheap helmets have the same protection. and helmet laws may kill people than they save. http://www.wearyourhelmet.org/helmets A concussion can happen when there is a blow or jolt to the to the head, and it can cause the brain to move around rapidly inside the head. It could be severe or mild brain damage, it can interrupt how the brain functions.
Like we dropped a helmet with a weight ball in it from 41 meters high and it protected the ball.
when you hit your head you could damage one of your lobes, for example you hit the front of your head where your frontal lobe is located if you hit it hard enough you could mess with how you make decisions. |

Delilah & Ashley
Introduction: Hypothesis: Here is a link of our design we planned out; https://docs.google.com/a/animashighschool.com/drawings/d/1JPKMZQneh4jRt4UWkgswYFDMAbzlBmPkqvqQjmKQAf0/edit We planned that we could have a simple design for our fins it is kind of shaped like a trapezoid. Also we added some weight or mass to our rocket I, Delilah, have added mass at the top of the rocket. Ashley’s rocket has no mass but we have slightly different materials Ashley has cardboard fins and I have poster paper fins. At first we chose to test our fins but then we have decided to test our mass on our rockets because we had the same fins. Our question we used to come for the hypothesis is, how does mass affect the height of the rocket, “if mass affects height then we use lesser or more mass on one of our rockets because we want to see if mass will affect the height at which the rocket goes, because Ashley’s rocket went 45 degrees and compared to my rocket which had a lot more mass than Ashley’s it went 60 degrees. We think our hypothesis is good, written properly. Procedure: We have tested the mass kept the pressure, fins size (height/ width), and the water level, all the same. The only objects we have changed is the mass and where we put the mass. We were looking to see if the area of where we put the mass would affect the height at which it would go. Constant Variables Fins Size (width/ height) Pressure (PSI) Water Level independent mass Dependent Height (M) The variables we weren't able to keep constant were the shape of the bottles because we didn’t have the same bottles, and dimensions because I added the mass at the tip of the bottle which made my bottle longer and added more weight. At which Ashley’s rocket stayed the same. Data: Test Rocket Indpt. Variable Angle of Elevation Distance from launcher Hang time Height Ashleys “Mass” 45 “degrees” “16 M” .85 .27 Delilahs “ “ 60 “ “16“ .83 27.71 Ashleys “ “ 39 “ “ “16“ .90 12.95 Delilahs “ “ 25 “ “ “16 “ .99 7.46 Delilahs “ “ 31 “ “ “16“ .88 9.61 We chose to graph it like a scatter plot because our height is spread out. We collected the data by someone getting the degrees of how high the rocket goes and someone timing the hang time, also the person went back 16m to find the degrees. Mass and height scatter plot: this is our graph we weren’t able to figure out how to put the image here so here is a link. https://docs.google.com/spreadsheets/d/183omW4RPs6FcyIHObSzjI2JDFyKl5mwpou4iZlvAB1k/edit#gid=0 Conclusion: In relation to our hypothesis we were testing the mass to see if it would affect the height because we want to see if how much and where we put the mass would change how high the rocket went. Some problems we found out were that for one of our rockets the fins kept falling off so we recommend not to use hot glue, duct tape works fine. Testing helped us to find where we needed refinement on our rockets. We also recommend to others to stay with basic materials and not so expensive because your rocket might explode, get stuck in a tree, or land on the free-way. |
