Searches for the Supersymmetric Partners of the Top and Bottom Quarks at CDF

Within supersymmetry models there is a very good chance for the partners of the top and bottom
quarks to be the lightest quarks. In this case they might well be produced at the Tevatron ppbar 
collider. We present searches for these squarks using 0.3 fb^-1 of data taken by the CDF experiment at the
Tevatron. For sbottom quarks the experimental signatures are 2 b-jets and large missing
transverse momentum. For stop quarks we search for two charm jets  or
2 low pt leptons, 2 jets and large missing transverse momentum.
