So water is more attracted to itself than to the wax. Students should remember that water molecules are very attracted to each other and this attraction is the basis for surface tension.

The activity sheet will serve as the Evaluate component of each 5-E lesson plan.Safety, be sure you and the students wear properly fitting goggles.

Is this explanation enough?

Wet the toothpick with water.
Bring the toothpick close to, but not touching, the water drops.
In this practical, students observe and report what happens when water is placed o n waxed paper, and a splint or toothpick is positioned close to the droplets.

As with most quality science experiences, the materials are simpl e (water, wax paper, toothpicks and food coloring but the science learning.

Fill the small bowl with water and add a few drops of food coloring or liquid wate r color.
Tear off a rectangle of wax paper and use the sharpie to draw several small.
