Objective: Students will be able to identify liquid as an object. A liquid is an object because it can be seen, touched, or otherwise sensed.

Is a liquid an object?

Distribute dropper bottles of vinegar, water, cooking oil, liquid starch and have students use the activity sheet found on the activity sheet for Learning Experience #13 in the Properties Student Activity Book. (Please see PDF) Place a drop of each liquid in places marked with a V, W, O, and S. Have the students place one drop of vinegar on the paper near the label V. One drop of water on the paper near the label W. One drop of oil on the paper near the label O. One drop of starch on the paper near the label S.

Discussion Questions:

How do you know the vinegar, water, oil, and starch are liquids?

Have each student tape his or her paper to the window. On the next day observe the paper.

Discussion Questions:

Which liquids left a “print” or mark?

Is a liquid an object?

Describe how each liquid looks.

Do these liquids have an odor?

Do you think that liquids are objects? Why?

Extension:

Have students place a drop of each liquid on a piece of wax paper. Which liquid will flow fastest when students tilt the paper? Students may enjoy using a pencil to tease water drops apart and recombine them. Which other liquids have this property?
