Which part of the diagram shows a sediment?
Salad dressing is a mixture of multiple substances, similar to the food coloring mixture we separated.
Oil and vinegar are two ingredients in almost all salad dressings. We will refer to these as our base ingredients.
-Substances DO NOT DISAPPEAR!
-If you SEE sediment, the substance did not dissolve. If you DO NOT SEE sediment, the substance dissolved.
- Watch the video to see if the substance (ingredient) dissolves or does not dissolve
Sugar: Was there sediment after the substance (sugar) was mixed with water?
Sugar: Did the substance (sugar) dissolve in water?
Citric Acid: Was there sediment after the substance (citric acid) was mixed with water?
Citric Acid: Did the substance (citric acid) dissolve in water?
Pepper: Was there sediment after the substance (pepper) was mixed with water?
Pepper: Did the substance (pepper) dissolve in water?
Cumin: Was there sediment after the substance (cumin) was mixed with water?
Cumin: Did the substance (cumin) dissolve in water?
Observable Scale (What you can SEE)
-After mixing substance (solid) with another substance (liquid/water)
Which mixture has sediment?
Which mixture could represent a mixture of sugar and water?
Based on our experiment, what might be the solid substance in Mixture A? Select that apply.
What ingredients mixed into the water without leaving sediment (dissolved)? Select that apply.
Did the two different molecules connect?
Are the molecules attracted to EACH OTHER (high or low attraction)?
Did the molecules dissolve?
Did the two different molecules connect?
Are the molecules attracted to EACH OTHER (high or low attraction)?
