    I'm 13 and I know I'm not as advanced in science as many of the people on here. I'm currently doing a science fair project on Non-Newtonian Fluids- specifically a colloidal suspension of cornstarch in water and what affects different variables have on this substance. I understand that shear stress is the applied force needed to deform the fluid but is shear rate a different thing?
    I'm still not sure if this is too advanced for me and it may not be necessary in my project. I already have plenty of other information on Non-Newtonian Fluid (polymers, colloids, dilatant, rheology and Newton's law of viscosity)

    I currently have a rheogram that I may use but if someone would be able to explain this to me in a simpler way I'd really appreciate that.
