This is what I currently have as a project. The main overall strength would be my boat’s ability to not only float in the water but also be able to move both forward and backward through a form of energy transfer. In addition, my product is definitely safe for children, its main target audience. I sanded off any sharp areas, and even though the wood quality isn’t perfect, and some strips of it have gone missing, I still made sure that it was all sanded down and smooth enough, so there was no way a child could hurt themselves by touching it. However, some parts that definitely could use refinement would be my boat’s ability to move. The elastic band I used simply isn’t tight enough for the job, and to get my boat to move. It simply requires a lot of effort to turn the popsicle stick roars backward.

One piece of feedback I was given was to make the elastic band tighter. This was also the issue I just highlighted in my previous paragraph. To fix this issue, I will wrap my current elastic band around the popsicle sticks attaching it, to make it tighter.  Additionally, other feedback told me my popsicle sticks which are used to connect everything, simply are not glued on/ attached to the boat strong enough. This can result in the popsicle sticks over time losing force, and eventually, it will fall off the boat. To resolve this issue, I will simply take off, and reattach my popsicle stick to the boat, but this time use a different type of glue besides hot glue. Last time I used hot glue, but I was conservative with the amount I used, because too much hot glue can result in the foam being melted, and I didn’t want my foam to melt.  Some feedback on how to resolve this issue has been using tape, hot glue, or super glue. I’ll look into these different suggestions and try to choose and combine the best suggestions to determine what the best solution is.

 A rule I had to make along the way was the Crazy chaos mode. Basically, the rounds were taking too long and other people wanted to play the game and the line was looooooong. So the Crazy chaos mode is basically like a penalty kick. Each player will start free shots at each other.

Blog Post Reflection

 

Take a picture of your final apparatus (finished product). May include more than one.

 

Answer the following questions on a word document:

 

Why is engineering important?

 

-Engineering is an important thing because,

It can be used to create a design to help people and the environment.

 

What was your challenge?

 

-Our grade 6 challenge was to design a prototype,

that someone would like to buy in a store.

The prototypes purpose was to turn dirty water into filtered water.

Then into clean water.

 

Why did you choose that design?

 

I knew the moss in the dirty water would stick onto the pieces of cotton helping the end result.

 

How does it work?

 

First, there is a metal cliché. Then we stuck pieces of cotton on with rubber bands.

Finally, after the water went through that it went into a tube that leads to a cup with the clean water.

 

Was your design successful?

 

Half. In the end, the water cleared rocks and moss, but the water was still a bit dirty.

 

How might you change your apparatus if had the opportunity? (If no redesign)

 

Stick some metal cliché into

the tube so it would be more helpful.

 

(If redesign) Was your redesign successful?

 

There was definatley less dirt, but still a bit dirty.

Save on your desktop when finished. We will post it in your blog next week.
