revision of class challenge

Robotic Arm Challenge


Did you successfully complete the challenge? Describe how it went
I thought that the challenge went well because…
my group successfully completed the challenge and it was fun and it helps our brains think outside the box.




What are the rules, equipment, and tools that you used for this challenge? If someone else read this would they understand how to play?
A meter ruler was used to measure the distance that we needed put the coke bottle
You must raise the coke bottle up 15cm high before placing it down.




What are 2 more aspects of your design that you think worked well?
  • The paper structure we made was very strong and did not break while we were lifting the bottle.
  • the losa string
  • and teamwork
What are 2 more aspects of your design that you think that did not work well or as intended?
  • The lasso of string was hard to pull tight around the bottle and we had to redo it twice.
  • string
  • people


The name “Robotic Arm Challenge” is a good name for this challenge, can you think of 2 more names that you could give this challenge?
  • Levitating coke magic
  • wingarium leviosa
  • redacto


Room 11 and 12 are thinking of doing the same challenge, can you think of any tips and tricks that you could give them that would help them do the challenge better?
  • I would think of a different way of holding up the bottle instead of string because the string struggled to hold the Coke bottles weight.
  • put people on the other side.

You had only 5 pieces of equipment to use for this challenge, these were:
- Coke Bottle
- string
-  tape
- newspaper


If you did this challenge tomorrow what equipment or rules would you allow, switch out or take away?
- I would add in different shaped bottles some with wider lids than others so that we could pick them up in different ways.
- the bottle flip challenge
-
-


Find a picture of your creation…



When you have finished check that examples are detailed. Then make sure you have had it checked and had it commented on by at least TWO other people. Remember your writing goals for this term.


When you are done, post it to your blog.

lime battery

https://www.youtube.com/watch?v=GhbuhT1GDpIwe wanted to see how a battery worked we put a zinc nail and a piece of copper into a lime and connected it to a volt meter.
1 lime=0.95v
2 limes=1.96v
Image result for how does it work3 limes=2.9v and lit up a LED

questions and wonderings
rm 10 002.JPG-does it depend on the size of the lime? (no)
-what if I put more nails and copper in? (it wont work)
-can I use different metals? (no)

the way that it works is the zinc and metal in the nail runs through the lemon. so, in conclusion, you can use anything that has enough fluid for the metals to flow through.

we also found out that a single banana holds(1v) which is .5 more volts than the lime
