AIM To see whether the height from which blood is dropped from, has an effect on the appearance of the blood splatter.
HYPOTHESIS If the distance at which the blood is dropped from changes, then the splatter of the blood will change in transparency, surface area and shape.
VARIABLES Independent- The height at which the blood is dropped. Dependent- Size, shape and transparency of the blood splatter. Controlled- Surface, Angle blood dropped from, Amount of blood dropped, Location (i.e. outside)

MATERIALS
- Dropper
- 2 x 1m Ruler
- Blood (Red Food Dye and Dilute Topping)
- Butcher Paper
- Camera
- Pen/Pencil
- Set up the experiment by placing the Butcher Paper onto a flat surface
- Ensuring that the ruler is at a right angle to the paper, drop the blood from the following intervals (only do one at a time) 1cm, 10cm, 30cm, 50cm, 75cm, 1m, 1.5m, 2m
- Record your results by writing the distance next to the splatter and then take photos.
DISCUSSION Through the results, we can see that from the 1 cm to about the 30 cm drop, the transparency of the blood splatter becomes increasingly obvious. We can also see that even beginning from 50 cm, 1 m and more obviously 2 m, the blood splatter becomes not just one shape but a number of different splatters. It is also observable that the size of the blood drop steadily increases as the height the blood is dropped from increases.
CONCLUSION From the results showing that the transparency, size and splatter increased when the height increased, we can support our hypothesis that when we alter the height which the blood is dropped, the shape transparency and platter changes.
