Small objects around your house that have different sizes (volumes) and weights (masses). In the video, I used a die, screw, penny, popcorn kernel, grape, and bottle cap.
Procedure:
-
Measure out the substances into the five containers. Measure out 3 tablespoons of each substance and put it in its own container.
-
Clean off tablespoon after measuring out each substance.
-
Honey goes in the glass first. Be sure not to get any on the sides
-
Next, use the turkey baster for the soap.
-
Wash out the turkey baster after each time you use it.
-
Use the turkey baster for the water.
-
Use the turkey baster for the oil.
-
Use the turkey baster for the rubbing alcohol.
-
Let all the substances in the glass rest for a few minutes so that they can separate out and the layers are more visible.
-
Now take all of your small objects and drop them into the glass. See where they land. Why did they land where they did?
