What is this engineering task?
To make a product that contains energy transformation.
What are you thinking about doing?
To make a toy that can converts energy.
Embed images and links of idea you like/ don’t like?
This design is using energy that it is created itself. I don’t know whats the design is for but I like the design.
I like the design it has, and it brings joy to kids. But what I don’t like is that you have to charge it by using electric energy.
Analyze those ideas: What are the pros/ cons about those ideas?
Wasting energy. We should start to consider the future by stop wasting things.
Making a toy for cats. (Love cats forever!!!)
First Step to Make my toy: (Learning skills)
- The energy that will contain in this toy will be electric energy, light energy and kinetic energy.
- I need to learn how to let the toy to get charged, and how it can transfer to kinetic energy and light energy.
A plan for the next 4 lessons :
During the first lesson I will mostly be experimenting on how to make an elastic car. So, if I fail the first, second, or third attempt I will still have enough time to reflect on each of them.
I will focus on writing a reflection, and how will I improve on the final product.
During the third lesson, I will be making the final product and putting the decent outfit on the elastic car (that will be the mouse).
I will write a paragraph about how one energy transforms into another energy, and check if everything is ready to go.
I used caps for the wheels, and as a result, it didn’t work. The wheels where turning but it stayed at the same place. The reason I think is that the floor is too slippery for the wheels. So after a discussion with the teachers, I changed the wheels.
Then, because I didn’t stick the materials together well; as a result, they fell apart. So I had to make another one. The second time, I decently attached everything together and changed the wheels and put the outfit on. The final prototype came out as I had expected.
This is my final Product of what I made.
Differences: I changed from electric energy to elastic energy. The reason why I changed is that if I had to do electrical energy I then need to include coding and other things to let it work. By making it go, there is an easy way of doing it; it’s by making it work with rubber bands. The benefit from it is to save energy.
The second thing that I did differently is making it from a mouse to a squirrel. The reason for this is because I didn’t find any cute looking mouse from TaoBao so instead of buying a mouse I bought a squirrel.
Why it worked:
I used an elastic rubber band and stabled it in-front of the car then, I pulled it all the way to the back and put it on the little stick and turned the wheel, so the rubber band could get tied. After you have tied it enough, you put it on the floor and release it, elastic energy will appear, and so the wheels start moving. By running, immediately the elastic energy will turn into kinetic energy. and by rubbing the floor, the kinetic energy will decrease, this causes the car to stop slowly.
Materials I needed:
One rubber band
One long stick
Two popsicle stick
Different quality of wheels and a out fit
I tried two times to make it work:
where I did well,
I did well on making it work. It came out successfully.
Where I need to improve:
The tail from the squirrel is too long, I need to consider the tail not being suck from the rubber band when I turn it. I could find out a method to fix it.
I would highly recommend the people who have cats at home to buy it. The benefits are, this cost won’t be high because it’s cheap but with good quality. It is an environmental toy, and you won’t need to charge it, only turn the wheels and let it go.
