Part 2: Mixing water with flour
Hypothesis: If we mix water with flour, then the flour _will not be_ dissolve, and become a _heterogeneous_ mixture, that can be separated by _filtration_.

Part 3: Mixing water with Salt Hypothesis: If we mix water with salt, then the salt _will be_ dissolve, and become a _homogeneous _ mixture, that can be separated by _distillation_.

Part 4: Mixing water with oil
Hypothesis: If we mix water with oil, then the oil _will not be_ dissolve, and become a _heterogeneous_ mixture, that can be separated by _separating funnel_.

Instruction: After you have finished the experiment, answer the following guide questions:
1. Which Mixture was Homogenous? What properties did the mixture show that made you certain of your choice?

2. Which Mixture was Heterogeneous? What properties did the mixture show that made you certain of your choice?

3. Why water is called a universal solvent? Why do you think water is present in all of the mixtures?
