What would be a good science experiment?

Question

I need a 5th Grade science experiment.

Answer 1

Take a huggies diaper and a pamper diaper and see which one holds more pee.

Answer 2

create a type of bridge and explain which designs are stronger for certain conditions...for example

a suspension bridge is clearly not a good choice in a place where there is a lot of wind....u could show that by making a mini suspension bridge and bring in a fan to immitate the wind.

i did my project in grade 6 on this and got a great mark. Hope i helped, and good luck!
