This term we have been exploring our curiosities by researching information about different inventions. We had to think of real word problems such as transportation, pushing a heaving trolley and not being able to take a trampoline with you. We used the design process to help us with solving these problems. We had to think of possible solutions and research how our inventions would work. We also created prototypes of our inventions using a website called tinkerCAD. Below are some of our invention groups.
Our group made a hover scooter.We made two prototypes of our invention and the first one was like a frisbee, the second was a big model that had most parts and looked like the plan. We also made 3 different books. 2 were explanations of how our scooter worked and the other one was about all the different types of hoverboards.

Each group made an invention using teamwork. Our group made jumping boots so you can jump as high as a house, because you can’t travel with a trampoline. Other groups made cool inventions too. We have been working on this for 1 whole term.

Remote control trolley
My CBL group worked well with our invention called the Super Push-R or the SST (self steering trolley). We made a prototype with one shoe box, 4 pencils, foam wheels and lots of tape and an antenna. Our group did lots of research on controllers and how they work. We found out that radio waves are sent to the car from the controller.

Trolley with fan
My group invented a trolley which moves by a fan, it also has wheels at the bottom to make it move.The problem is that when people go shopping and they have a heavy trolley it can be hard to push or people with broken arms can’t push trolley So that’s why our group decided to create a self moving trolley.
How it works:The fan works because the blades in the fan are connected to a battery creating an electrical current. This current is caused from the battery which connects to the DC motor. The blade is attached to the DC motor so the blade will spin and make the trolley move. To make our prototype we used a propeller for the fan, 2 pencils to hold the wheels, some foam for the wheels, wires to attach to the battery and the DC motor which made the propeller spin.

I made a smart desk because some people don’t have enough storage on their desks. I made this by researching materials desks are made out of and using this to help me think of what i would use for my desk. I also researched how wires and buttons work so then i would be able to explain how they would work in my desk.
Fold up trampoline
We made a fold up trampoline because we wanted to take trampolines and the fun with us. First we needed to make a design of what our invention would look like and a prototype of our invention. We had to find out what trampolines are made out of in order to be able to make our trampoline. This took us a long time because we had to measure and we needed a few materials.

In 4E we have made inventions to show our curiosity. My invention is a google door if you want to know how it works all you have to do is step on the pressure pad. Then the wires from the pressure pad will send electricity to the sensor which is at the top of the door. After that the sensor will sense a person on the pressure pad then the door will automatically open for the people that are standing on the pressure pad. We have also designed our invention’s on a website called tinkerCad. We even had to make books about our invention’s and how they work. The students also thought of something called the invention Convention where parents come in the year four’s classrooms and look at their designs and the year four’s have to tell them why they invented it and how it works.
Self Stering Bike
My groups problem was that my feet get tired when riding a bike, so we made an invention of a bike that has buttons and these buttons can do different things. One button is for go and the other one is to stop. There is also some other buttons which can do different things. For example folding and unfolding the umbrella. This bike also has an incredible fan and this fan can make you cool down in very hot places. First we had to draw a diagram of the bike including all the key parts such as an umbrella, fan, basket and the buttons.Then I wrote persuasive about my bike invention and when I finished my writing I drew a diagram and it was hard and I had to keep on drawing it which made me stressed. I did lots of research about bikes to help me think about how it would work.Then I finally made my prototype. At our convention we got really good feedback from people like : super cool job. Great job. Great work your bike looks cool. Love the bike. Good work girls. How did you make it? I love your design.

Our group made a tap that you pull something to make the tap turn on. We did this because it can sometimes be hard to turn taps on and off. We worked in a group of three research, plan and make our prototype.
