What is a good extra credit science project for a seventh grader?

Answer 1

Build your own lamp. You can find instructions on how to do this on the internet, and its fun; you can decorate it and keep it in your room afterwards -- what are you going to do with brine shrimp once your project is over?!

Just hassling you, answerer #2, I do think that is a cool project too! :)

Answer 2

I was just thinking about science projects today. This will take several days and 2 different rooms and at least 10 volunteers who will eat soup/chili, etc. Maybe even get a few teachers involved.

When I was eating my lunch today, soup, I was thining about how I heated it for 90 seconds. It didn't taste as warm as when I usually heat it for only 60 seconds. I wondered if the surrounding air made me think the soup was colder. Last time I ate soup it was warm outside and the windows were open. Today the heater is running and it's cold cold cold outside.

SO, if you have 2 different rooms on several days you can change the temperature of the rooms and experiment with the temperature of the soup. One week the room can be sweltering hot. Heat the soup to be just above room temp one day, the next day pretty cool, the next day really hot, etc. They can fill out questionaires and discuss the taste and quality of the soup and talk about the temp of the soup, too hot, cold, just right. The next week make the room be pretty cold and do the same stuff with the soup. You'd probably need a thermometer for the soup so you can document the temperatures for different days.

Answer 3

Experiment with different types of laundry detergent and which cleans the best. I saw this at my daughter's science fair and thought it was interesting. She dirted six different white t-shirts with the a spot of pen, spot of dirt, spot of grass stain and so on. The shirts were then washed in six different detergents, Tide, Era, etc. She then reviewed her data and judged which was the best for each certain stain. I thought it was rather clever and was surprised what detergent was actually the best.

Answer 4

A paper on a robust definition of science. Too many adult scientists don't know what science is and isn't and don't know how to create good definitions.

Answer 5

Build an AM Crystal Radio entirely from scratch -- yes, that means making your own "diode" using a galena crystal, and winding your own coils, and even making your own "headphone."

Answer 6

mutate brine shrimp to live in brackish water (not that hard, i did it in 3rd grade) just start with full saline water, add the brine shrimp, as they reproduce slowly add distilled water bo do not increase the salinity eventually you will have brine shrimp that can live in almost fresh water. (takes a while)

Answer 7

I'm in 7th grade too, and i suggest the solar system or weather mapping, you know like diagrams of fronts? hope this helps you.

Answer 8

Do you know what is bio diesel? Do that, trust me it will work...
