I Need Some Ideas For A Science Fair Projects My Daughter Is In 5th Grade,Can You Help Me?

Somethin on does the way people percieve taste I did this and got a good grade and it went to the science fair

You should do the mentoes project first you will need to buy the candy named mentoes you most likely will need the discolored ones because the colored ones might have a different affect on your experiment then you will need to buy 3 DIFFERENT types of 2 leader sodas then you will need 1 stop watch and 1 camera (does not matter what type of camera just make sure they can be printed out) 1st you will need to open the 2 leader bottles in a line one next to the other showing the labels in the front and in one of them drop a men toe in and have the person taken the picture to stand back and hold the camera in the camera taken Poisson and have the person with the stop watch in there Poisson to start and stop time when needed to do so then when the soda in the soda bottle shoots up have the person timing time it and have the person taken the  picture take the picture and just keep on dropping the mentoes in one after another.HOPE SHE GETS AN A!!!!

1.) 4 lucky bamboo water plants    a.) 1st plant sitting in a window (only water)    b.) 2nd plant sitting in an area with no sunlight i.e. Closet (only water)    c.) 3rd plant same as second plant but with 1 table spoon of glucose (corn syrup will do   fine) mixed in water.    D.) 4th plant sitting in a window (water+what ever food coloring you want)    (may want to use a celerystick instead of a bamboo plant for the 4th one. I'm not 100% sure that this will work but I know it will with a celery stick.)    - This project will show and prove photosynthesis as well as the true power of the sunlight
