I need some help! I am helping a student with a 4th grade science fair project and I need to to be top notch.

My wife is a 4th grade teach in a school that is considered Title 1. That means more than half the kids are on free/reduced meal plans. She has this sweet kid in her class that is having a rough go at life. He lives with his grandmother who probably does not have much more than a 6th grade education and cannot help him. His dad is gone and his mom is currently in prison for murdering his uncle. He also lives with his 2nd grade brother who actually witnessed the murder. But he tries to have a positive attitude but some days he is just down. My wife said he came to her worried about his project so I need to come up with some ideas.

My first idea was a project on electricity. I was going to have three power sources like a hand crank, solar cells, and either a turbine or water (haven't figured out the last ones yet).

I would then have something powered like bulbs. Maybe have a switch to two different types like led vs incandescent. Ultimately to show how electricity can be made and how efficiency effects power.

Nothing too complicated for a 4th grader. I want to have some good ideas but I am going to guide him through putting it all together.

So any ideas besides a plane on a treadmill? I was also thinking about making a wind tunnel but haven't figured out how to make smoke that won't stink up a classroom.

Here's what you do.

Construct a model of a small town with buildings, roads, little trees, streetlights the works. Then put all the solar cells on the roads. This project will be a model of solar roadways.

If he doesn't get an F take him out of that school immediately. This is a 4th grade project. The school is being tested here more than the kid.

wind tunnel's a fun project. you just need a fan, cowling, and a ton of straws.

What would you demonstrate?

I feel the electricity demonstrator is a good idea.

Something like how buildup on the wing affects lift. Or maybe have a wing with dimples to see if it works better. But to demonstrate that you would need some type of smoke going over the wing.

I always won when I did a Hydroponics project (this was 3rd and...7th? grade). But then, that was a time when we still did space travel.

However, never underestimate the power of the college-age stoner honors students that are judging these things. Still, it's a rather easy and cheap project to do, requires patience and you can actually see your results. Does take time, however. You need to plan ahead by about 2 months? or so, to have some measurable results from sprouts.

The couple times I judged science fairs, the judges focused on whether or not the kids were employing the scientific method. Was there an observation, hypothysis, testing of hypothysis, data evaluation, conclusion? The electricity idea sounds good but make sure the kid is demonstrating a use of science and not simply a tech demo.

The kids who won didn't necessarily have the coolest or fanciest projects but had the projects that were really science projects.

Get the kid to brainstorm with ideas; then advise him.

He needs to do the work; not you.

The intention is a learning experience by him :colbert;

I intend to guide him and have him to the work. The problem is he has no internet access at home and I am not sure if his grandmother will let him stay after school.

This.

Don't just do a demonstration.

Plants are an easy one. Have a control, then an experimental group - (pick one or more) loud music, quiet music, an electric current, add soft drinks in increasing amounts (control is water, then a 10%, 50% and 100% soft drink or carbonated water, whatever), shaking it every day, etc etc. Compare different brands of fertilizer.

Then talk to the grandmother about your concerns and explain your intentions and proposal to assist him.
