I have a grade 7 science project due on Friday. I have to make a crazy gadget and I have no ideas. One kid is making a shovel with a flashlight attached to it for nighttime shovelling. What can I make?
Although I would like to give you ideas, this needs to be your project.
Have you ever had any frustration, because something was not available? Think back to any time when you said to yourself, "Boy, it would be better, if this this was available."
I hope this helps you to think of something. Thanks for asking.
