2. Background info
Why it’s a problem
Plastic bags kills sea creatures
It pollutes ocean and air
It doesn’t rot down until 100’s of years
later
3. Develop a plan
Make more bags made out of paper
Find out what is already around
Decide on the shape of the bag
Decide on the size
Find a box about the same size
Open it up to get a pattern net to trace
Trace it and fold into shape
6. Prototypes
I first made a VERY bad one from newspaper
that you could barely even open, and I made
it by just stapling a bunch of paper together
and now I will improve that...
Then I made a egg shaped one by paper
mache. I made another egg shaped one but it
was miniature.
After that made two one big, one small out
of only 1 piece of newspaper each.
7. How I made them
I got a weet bix box and took it apart and
copied the pattern.
Then I put it together with tape and glue
After that I made handles out of paper by
getting strips of paper then folding them
up and taping them onto the sides of the
bag.
8. How I made thempaper mache
On the round ones I made paste out of flour and water.
Next we blew up a big balLoon and a small balLoon.
Then we the used paste to rap newspaper around the balLoons,
so then we had to wait for a day for it to dry up.
One day later I popped the balloons with paper wrapped round
them, so now they were shaped like bags
So now all I had to do was put handles on.
9. How it worked
Plus Minus Interesting
It didn’t
It can’t hold
take very It was very
as much
long to light
heavy stuff
h
make
10. How it worked paper mache
Plus Minus Interesting
it was interesting
h
paper mache is paper mache that if you rap
strong and it takes a long paper around a
can hold more time to make. baloon and pop the
baloon it will be
stuff shaped like a bag
11. Test and evaluate
We went to the shop and tested the bags and they worked well
I put light things in . Tissues, cereal box, and small things. None broke
Next time they might need to be wider to fit wide things in.
FUTURE- I could see if anyone else wants to use
them. Probably shops would like the Rectangle ones
cause they are easier to make and easier to put things in.
12. IMPROVEMENTS to my final
prototype
Strengthened the round bag by paper
mache
HANDLES- I Added strong handles that
looked good too and stretchED WHEN YOU HOLD
THEM
I added an edging around the top to make it
stronger at the top and to make it look better.
