Blood is a red liquid that your heart pumps through your entire body. Blood carries all the nutrients that your body needs to live and grow. Normally you can never see your blood as it is inside you, but when you have an accident, cut yourself and bleed you can see your blood.
However, not all creatures have red blood. Some marine creatures such as horseshoe crabs and many insects have green blood, which contains the copper-based cyanoglobin rather than the red iron-based haemoglobin.

Mud is what you get when you mix water and dirt together. Mud is sticky, squishy, squelchy and great fun to play with. If the mud is really wet you can squish around in it, and if it is only a little bit wet you can mold it into shapes like mud pies.
Even though mud is so fun, adults don't like children to play in the mud as it is very dirty, and they don't want to have to wash your clothes afterwards.
