School Science Projects

My daughter chose “Will saltwater evaporate faster than water w/out salt?” and my son chose “How does exercise affect the human heart rate?”

My problem is that research needs to be looked up and since I’ve very little education, it’s extremely hard for me to help them.

Please have mercy on me and kindly leave me ideas on how to help my kids or direct me to any websites that may give me as much information that is easy for me to understand and explain to my kids.

By the way they’re both in special educatioon classes so now you understand how much harder this subject is for me.

Want some science experiments for class6 students.

what should happen if you put three coveredcontainers in the freezer, two filled with water, one of these has been taped and one empty container overnight? Should the filled water have blown the lid off due to the force of the expantion? That’s what I think, but it’s not working…darn kids science projects!

I’m looking for online sites which allow advertising of science supplies to teachers for grades 7th on up. Even college level. Also interested in advertising to parents looking for science supplies for their kids’ projects. Free ads, US-based preferred. Thanks.

Of course, I sign up for the science project seminar at school and I suck at science. But, I want to prove to myself and others I can do it. I’m in 10th grade, but I really don’t want to do something 10th grade level, knowing these kids’ projects are going to be pretty extravengant.

Any ideas?

Thanks in advance
