Scientific Drawing example - Draw ALL your materials and label them!

Data Analysis Your topic sentence re-states the two variables and states the relationship between them. Your yellow sentences explain the results from each trial (you will have 5 yellow/pink sentences) Your pink sentences go into further detail describing how each property test helped you to identify the mineral You formally conclude the relationship between the two variables by stating which mineral you had. Don’t forget transitions

Data Analysis Example The relationship between [IV] and [DV] was___________________. First, I tested hardness by ______________. This helped me identify my mineral as _______ because _______________. **YOU WILL HAVE 4 MORE SETS OF YELLOW/PINK EXPLAINING HOW EACH PROPERTY TEST HELPED YOU TO IDENTIFY THE MINERAL. **** and a conclusion
