Mix half a cup of light Karo syrup with several drops of red food coloring. The mixture is a little thick but still works. (Alternative, come in to my room and use the prepared blood solution that I have.)
1. Go outdoors and spread four sheets of newspaper across level ground (not hard surface). (Don't wear good clothes for this lab!)
2. Dip a butter knife or plastic knife into the "blood." Hold the knife at a height of 12 inches and walk across the first newspaper, allowing several drops to fall. Label as 12 inch blood drops at 90 degrees.
3. Repeat step two but hold the knife at 24 inches. Label as 24 inch blood drops at 90 degrees. Repeat step two at 36 inches and 48 inches.
4. Place four new sheets of paper on a gentle hill. Repeat steps 2 and 3 at each height. Label appropriately.
5. Place four new sheets of paper on a steep hill. Repeat steps 2 and 3 at each height. Label appropriately.
6. Find a piece of cement or wood and do steps 2 and 3 at 90 degrees on the hard surface.
6. Allow drops to dry then fill in the form that accompanies this section.
