Evaluation for Inventions and Inventors

Evaluation
This unit was a called “Inventions and Inventors”, it was a fun and interesting unit. Aiste and I had some difficulties in the beginning but at the end it was easy and fun. This project was focused on human ingenuity and risk taker. We the class chose these two because it seemed to be the most well connected. By being a risk taker we take risks and as an inventor we need to take wild risks don’t knowing weather it will succeed or not. Without being a risk taker a person can’t experience new things.
Then we chose human ingenuity because inventions are something that Man make and invent. We invent new things for a good cause and sometimes for a bad cause. For this unit these two things fit the best.

Investigation:
For the investigation we went online and started to research. We even did a survey of the class. We asked our classmates and over a half of them said that they did not want to buy it because it is not that necessary. We also researched by using books and internets and found some facts. We found that there is a solar panel that can also heat up a building and etc… We tried to get as much as information but there didn’t seem to be a lot. We also looked at pictures of normal key detectors and got some ideas of how to design our key detector. During the research although we couldn’t get as much information as we could have we got the basic and essential ones. We found few information on the different kinds of solar power and how the solar panle on the calculator works. We also found out which parts to change to the key detector and which parts to make better.

Design:
Aiste and I had started on our design a bit late. No matter, we had come up with a good design. We decided to make a 3d model of the solar key detector instead of a poster. We were going to have the actual feature of the detector. It was going to be big so, everyone could see it and it was going to be interesting with wires inside it, showing. Our design of the solar key detector was that on the front there will be a speaker, solar panel, 2 lights and a button to press on. On the back would be another solar panel, speaker, censor and a battery change. We decided to have 2 solar panels and 2 speakers just incase the key detector is put upside down. We thought of many different designs but after combining our 6 other designs we came up with this one. To us, it seemed efficient and useful. Also we decided on that the key detector is 7cm width and 8 cm length. We also decided that there are different shapes and colors. This way we thought that it would attract more buyers.


Plan:
Our original plan was to meet on Saturdays and Sundays to start and finish the key detector but it did not happen. We did not meet on the first Saturday because of some reasons but we did meet on Sunday. Although we did not meet on Saturday we had most of the material that we needed ready like the spray paint, glue, tape, box and oasis and so on also not to mention wires… Also on Monday we worked on some more of the design and typed some information. Also we spray painted the box after school. Then on Wednesday we typed all the information and it was ready. So, then we were supposed to meet again on Saturday the 6th and Sunday the 7th but we only met on Sunday and printed everything out and started to glue everything on the box. The plan was changed from time to time because we did not have the time to meet, but we still got it done: D.

Create:
We created the box and it was a lot of fun. While, spray painting the smell of the box was horrible and very very strong but we dealt with it. We had not bought enough black so, we ended up cutting up half of the box in order to keep it pretty. While creating it we did have some problems for instance the glue did not stick onto the oasis and that the smell of spray paint was too strong that we had to do it carefully. We overall had fun creating this product. The box was interesting enough on the inside with all the wires and information. The outside could have been done a bit better but we’re both very pleased and satisfied with it.
