Invention Challenge 1

2017 - 2018

 

Cheddarchunga

Designers:

James and Marian

 

From the makers:

Our vehicle is called the Cheddar Chunga. We thought of this name because the middle of the car kind of looks like cheddar cheese. Some of our not bad distances are 4ft 7in and 5ft 7in but we also had a lot of good scores like 41ft and 37ft and 21ft and 3in. What improved us is that the less the weight then the more on vehicle. Our vehicle went further because our weight and the big hundred square in the middle also helped it by giving it a little bit of weight but not too much. The little more weight gave it a little push.  But then both of us tried to improve it by putting another hundreds block on it but that slowed it down so we took it off. This is the story of the Cheddar Chunga.

Theories:

1 One of our theories is that the lighter the farther. We think this because if there is a lot of weight then it will push down and it will slow down the vehicle.

2 Another one of our theories is that if it is long then then It will get farther because then the parts would stick out farther

3 Our last theory is if you have more wheels than it will go faster and improve your speed.

                               

Status:

Best distance: 41' 

Competition status: Gold medal winner

 

 

Ace

Designers:

Charlie and Connor

 

Note from designers:

The history of vehicle is we started off with a vehicle that got 15 feet. Then we got another vehicle and we had two vehicles and we improved a little but not enough to be the best in the class. We then got 25 feet with Ace but not the favorite in the class. We then in the first round got 37 and 2 inches. We were now the favorite going into the semi-finals and then got to the finals. We lost in the final  but made it to the Grade cup. We improved our vehicle at the last second. We tried different things and our vehicle got 20 more feet. That was a  big improvement so we decided too not do anything to our vehicle. We are very happy for our vehicle ACE.

Theories:

Big wheels are better.

The more wheels the better.

The smaller the vehicle the farther it goes.

  

Status:

Best distance: 39' 4"

Competition status: Silver medal winner

 

 

Snake

Designers:

Bethiah and Kevin

 

From the makers:

It all started out with a sideways version of the car. It was only going 10ft and we called it 'the wings'. But then Oumniya saw our problem and said, “we learned that it works better if you turn it sideways.” I took that evidence and changed our car.  Then it started hitting the wall.  Keven and Bethiah had a competition to see which car we would enter to the final. Bethiah's car won and the Snake was born.

 

Theories:

Big wheels in the back small wheels in the front so it goes faster

Stoppers to stop the wheel’s from rubbing against each other

Symmetry is the key or it will go off to the side

 

Status:

Best distance: 34' 8"

Competition status: Bronze medal winner

 

 

Gummy Cocktail

Designers:

Jonah and Sarah

 

From the makers:

Our first vehicle was an intermediate start. It got around 18 ft. reliably but it was not enough. We scrapped the vehicle and moved on to a remix of a classic four wheeler. Didn’t have much of an improvement from the last but it helped us come up with the name, “Gummy Cocktail.” We finally scrapped the second piece because we needed something better. While Sarah was absent one day though, Jonah made a very cool looking vehicle. Jonah didn’t test the vehicle however, and the next day we figured out it was stupid. We took away all the décor and just stayed with the core of the vehicle. It got to “25’10” but it was not reliable. We tried putting weights on our vehicle because competitors were getting successful attempts with weight. It went a little haywire though and we decided it wasn’t worth it. We don’t know what happened, but when we went back to original, it suddenly got “25’10” reliably.

 

Theories:

1.       Wheels vertically apart. Just about 1 centimeter will do the job. This way the wheels will be able to milk all the speed out, getting it farther than if not using this theory.

2.       Use big wheels because it will make it go faster. The bigger the wheels, the more space it will have to roll.

3.       The wheels cannot me to close to anything – including other wheels – because the friction will jam up the wheels, and slow the vehicles down.

 

Status:

Best distance: 31' 3"

Competition status: Fourth place

 

 

Fred's Glitter Ride

Designers:

Ava and Nathan

 

From the makers: 

At first Fred’s Glitter Pickle was hitting the wall constantly. Right before the first competition we wanted to try to improve it by making the wheels tighter but that only made it worse. In the competition we got disqualified with a distance of 17 feet. The only problem was that it had curved during our first run in the competition. Before, during our first time testing in the hallways we got 32 feet and 2 inches. We were hoping to at least make it in third place so we could be in the grade competition.  Before we had made Fred’s Glitter Pickle we had made other prototypes that hit the wall constantly.

 

Theories

1.     Using stoppers next to the wheels so they wouldn’t slide across the axle

2.     Using the same sized wheels to keep balance

3.     Only using four wheels so there wouldn’t be anything holding it back

 

Status:

Best distance: 17' NEW WORLD RECORD

Competition status: Quarter finalist

 

 

Santa's Sleigh

Designers:

Lina and Milo

From the makers:

Santa’s sleigh started off with Lina’s prototype and Milos’s prototype They tested them both before deciding to work on Milo's. They went through five names before deciding on Santa’s sleigh. Red arrow, Barry Allen, Stinger, American eagle, then we looked at our box.We saw a Santa’s slay sticker on our box. That’s why our name is Santa’s sleigh.  After Milo went to India for 2 weeks, I had to work by myself and I kept the same prototype and made a few changes to fix the friction and shape. We thought that if we added stingers to the top it would do better but it just got caught on the ground and added friction. But the weights that were used in all of our designs worked very well and we put six wheels in all of our prototypes to make it longer because it might get farther.

 

Status:

Best distance: 29'(11"nd best distance of all-time!)

Competition status: Quarter finalist.

 

 

The Spire

Designers:

Aaron and Oumniya

 

From the makers:

History of The Spire: The Spire’s original name was The Dominator. It’s also the second model. The Spire/Dominator for some reason would always do better in the hall and we still don’t know why.  The Spire stared out very sloppy and big. It was bulky and inefficient so we decided to scrap it and start from scratch. Our second model was much better than the first so we kept it. Our second model had big wheels in the back and small in the front. It also had one yellow gear at the back. We encountered a very big problem and it was the craft was bending. We tried to fix it by taping on supports but that didn’t help so we just kept them anyway. Then we added some wood blocks to add weight and we noticed a drastic change in distance. 

 

Theories

Theory #1: The more weight the better because your vehicle will gain more speed with more weight

Theory#2:  Rectangular frame are better shapes for hulls

Theory#3: More wheels will do better because it adds weight and more traction

 

Status:

Best distance: 20' 6"

Competition status: Quarter finalist

Bullet Train

Designers:

Tyler and Catrine

 

From the makers:

In the beginning our car didn’t go that fast but as we added upgrades to our car it increased its speed and range. Our car was only going 10-12 feet and the end of the classroom was 25 feet, the car also had steering problems it would turn left and right rather than straight. So, we completely took the car apart and tried different sizes and wheels and after trying out different styles we found a car that had the best range and speed out of the different cars we made before. The car was working very well the length was getting better but at one point the cars speed was going down but once we saw the problem we fixed it and then at one point it reached 25 feet! Once we started to test it a lot more the car started to only go about 15 feet and we tried to fix it and try different methods but it would not work so we took the whole car apart and tried a different model but that did not work so we rebuilt the old car and now we are just hoping for the best.

Theories:

·         If you want to have a good fast car you need to watch the speed of how fast

·         The heavier the car is the faster the car will go to make it go further  

·         Symmetry helps the car keep its balance so it doesn’t lean

·         Make sure that the car does not have any friction  

 

Status:

Best distance: 34'  6"

Competition status: Gold medal winner

 

 

Meteor Strike

Designers:

Quinn and Josh

 

Note from designers:

We started off with a vehicle that turn to much and went 10 foot 10 inches. We then decided to make a different vehicle. One day Josh started rolling 2 wheels down his notebook and it gave me an idea. My idea was to put 2 wheels touching each other and make it really tight and my idea worked! On our first try we got 20 feet. Then we added some weight to the back of the car and it started hitting the wall! That meant that it was going 25 foot 10 inches! That was our experience with our car, Meteor Strike.

We think that we might do pretty well in the competition. We are very confident in the vehicle and ourselves. 

Theories:

·        Make your car heavier in the back so there is more pressure.

·    Tighten your car’s wheels so that it does not turn and hit something.

·    Before you roll the car down the ramp, make sure that it is going straight.

 

Status:

Best distance: 30' 2"

Competition status: Silver medal winner

 

 

Salad

No photo provided

Designers:

Claire and Olivia

 

From the makers:

Salad has had an impressive start. We were experimenting with different designs, we built this design for fun thinking it would fail; it ended up becoming extremely successful getting 25ft 10in first try. This prototype ended up becoming a class favorite.  Being the class favorite definitely had its advantages. Salad got 25ft 10in in every test run, except for a few false starts. Salad has many prototypes, (Salad, Salad*, Salad-, *Salad*) each were very similar, but had small differences. Such as less weight, more weight, small, large, or symmetrical. We are very excited to enter the completion.

 

     Theories

·         Having extra weight helps the car go further

·         Symmetry helps the car balance out

·         You want balance so your car doesn’t flip over

 

Status:

Best distance: 34' 8"

Competition status: Bronze medal winner

 

 

Red Blaze

Designers:

Aiden and Angelo

 

From the makers:

We started with one K’nex in the middle to connect with the wheels. Then after a few test runs we noticed that we had a steering problem. Every time it turned left or right after rolling for about ten feet. We fixed the problem by connecting two more K’nex on the sides to make it more stable. After putting the K’nex on the sides it started to go more straight and our average distance was about twenty feet. When we did our official test to get into the competition our distance was twenty-five feet and eight inches. In the competition we expect to make it to at least the second round. We can’t wait to compete in the competition with our car The Red Blaze.

 

Theories:

·         Large wheels because they have more power and are stronger.

·         Short car because it will accelerate faster

·         Light weight because heavier cars will slow down once it goes down the ramp.

·         Wheels should be symmetrical because one of the tires won’t take control and make it turn

 

Status:

Best distance: 31' 8"

Competition status: Fourth place

 

 

Wacky Mobile

Designers:

Jonathan and Davis

 

From the makers: 

It went from big and bulky to skinny to looking like a motorcycle to what it looks right know. We are trying to beat 22’6. Davis named our vehicle the Wacky Mobile because it looks wacky! Our first attempt we got 8 feet. We kept changing it and testing it. On the sixth time we tested it, we got 22’6! We got into the competition with a distance of 18 feet.

 

Theories:

·       Force to go down the ramp

·       Speed to get to one place quicker

·       All the wheels  have different sizes

 

Status:

Best distance: 29' 10"NEW WORLD RECORD

Competition status: Quarter finalist

 

 

Sun Car

Designers:

Lilly and Carmen

From the makers:

We started out well. On our first prototype we got twelve feet. We tried out many types of structures and worked on weight. We tried 3 K’Nex then one and finally figured out that two is just right. The size really got us but, we decided that using one size (The orange K’Nex) is just right. Then we started taking trials and Mr. Allen mentioned that we should making our vehicle more like the structure of a car. Our trials after that point started to get progressively  better and better. The length went from 14 feet to 15 to even 21. Then we knew we were ready to enter the competition.

 

Theories:

Symmetry is important because it stops the vehicle from turning.

You need the right sized wheels so it will keep the balance with the rest of the structure.

Having weight on the vehicle stops it from spinning out of control and, it keeps it on track.

It’s good to have objects that are at a good level so that it doesn’t cause friction, and so that the wheels stay secured.
