What's the difference between normal calorimetry and bomb calorimetry? Does normal just have constant pressure but anything else can change and bomb is the same idea but only volume can change?

In a bomb calorimeter, volume is kept constant, so pressure changes; in the other type of calorimeter, pressure is kept constant, so volume can change.

To add on, Constant P. Calorimetry (I guess this is the "normal" kind) gives you the enthalpy values. Both types are used to measure specific heat capacity.

The first kind that was gone over in lecture (two styrofoam cups) was a constant pressure calorimeter. The bomb calorimeter is one in which the volume is kept constant. It's called a bomb calorimeter because they are more prone to explosions as the pressure changes, but not the volume, leading to high pressure in a small area.

Bomb calorimeters keep constant volume while the other kind keeps constant pressure.

yeah the bomb calorimeters keeps a constant volume while the other keeps constant pressure. he might do examples on it
