We need creative and simple ideas for a grade 7 science project where a chair must be made from recycled stuff
Question:The chair must have another purpose besides being able to sit on it. It has to be made out of plastic, wood or metal or something like that (i.e., a bean bag chair is not allowed) or some combination of these and the student can't start with an existing chair. She has 12 days to put this together and take it to school.
Answers:
The easiest chair you can do is one using recycled card boxes
Glue 20 in. squares of cardboxes, until you have a tower of about a foot. This will be your base.
Now glue 2 feet X 20 in rectangles of cardbox one on top of the other until it's 6 in. thick. This will be the back of the chair.
Paste base and back together. You can use a saw to L-shape the back and bond the parts better. Remember to use wood glue.
It will be kind of heavy but it's easy and cheap since you can find cardboxes anywhere. After it's glued you can paint it with acrylics to make it look good.
Good luck with your project.
a large rubber ball
an unsplit piece of wood
a small plastic trash can (like a bathroom size)
a milk carton
a large wooden cable spool
a large can (like those pretzel cans)
a 5 gallon pail/bucket (left over from paint, food stuff, etc)
you can use any of these with a wooden or metal frame as the backing where you make the frame so the items above just drop in
the bucket idea one can be used as a drum, etc...
I did this with my nephew for his high school woods class. They were to use reclaimed/recycled wood to make a writing desk and a chair. We got a store to give us a 4 wooden pallets. We carefully took them apart. The planks were separated from the supports. The supports were used to make the legs of the table and the front legs and back legs/back of the chair, as well as the cross supports and seat supports. The planks were sanded and glued to make the seat, and cut to make the back slats of the chair. They were also sanded and glued together to make the table top, and skirting edge(the part the tabletop rests on, two planks doubled up to give the thickness needed). Everything was sanded down from a rough 60 grit all the way up to a 600 grit sandpaper. Then food safe mineral oil(laxative section of most stores) was rubbed into the wood, followed by another sanding with 600 grit sandpaper. All excess oil was wiped off. Then, beeswax was applied to the wood to finish sealing it, rubbed in thick, excess wiped off, and then hand buffed with a lint-free rag until it was almsot mirror-like. The oil and wax bring out the grain of the wood.
If you do this, you should also document the process with photographs.

As your chair needs to have an alternate purpose to sitting, you may want to consider a more simplified valet chair such as is found here: http://www.highbrowfurniture.com/seating... .
Whatever you choose to use for the science project, I hope you have good luck with it and fun doing it.
Take an old wooden laddar. Cut one 3 ft section for back and three sections for sides and front. Make the seat out of woven rope. It could also be used for a silk flower planter.Good Luck
I have seen many pictures of chairs and furniture made out of pop cans, where they stack and glue the cans together in the shape of a chair, couch and tables. I have also seen furniture made out of cardboard, where they cut out a shape of the chair that they want and glue multiple layers together of the same shape.
