School Science Projects

The school is going to be having a science fair. As I am doing astronamy with them this term I was thinking of maybe incorporating the space theme into the science fair. I was just wondering does anyone have ideas of what we could present on the day???

Activities of what the kids have done. I was thinking of doing the Solar System Model with them & displaying that. I do not just want to put out one of there books of colour in pages in,as some parents may get upset as to why there kids books are not out. (books I was thinking of maybe giving the parents as gifts). During each process/stage of the making of whatever it is there will be pictures taken & will be put as a slide show on the day.

The slide show will consist of pictures during each stage of the material making of everyone & will be downloaded onto disk & put up for the parents to see the whole project through.

Any ideas of what I could make them do? or do with them??

I need some ideas for a little first grader boy’s science fair project. Something easy and not to expensive. And a first grader can understand. Nothing like a stupid potato clock.

Our child has a science experiment project where the instructions said to dissolve salt into hot water and then suspend a nail from a string into the water. We are supposed to report back what happens.

So, 5 days later, absolutly nothing has happened. Anyone know what was supposed to happen?

Is it possible we used the wrong type of nail (We used a galvanized nail), or maybe we didn’t use enough salt.

Please help in the name of kids science!

I’m applying for a job to be a camp counsellor for a summer camp where I’ll be teaching kids science through various activities and projects. In order to get the interview I need to come up with 2 ideas for such activities/projects. Any help would be appreciated.
sorry forgot to mention the kids are aged 6-12
