(312) 535-6390Objective:

This two day lesson is designed for an intermediate grade level.

After blowing bubbles, students will be able to test the effect of four

different shape wands and three geometric figures in a bubble mixture. Students

will construct water and soap molecules.Hypothesis:

Does a bubble always form a sphere?Materials Needed:

Dawn dishwashing liquid, cups, water, yarn, scissors, construction paper, glue,

pipecleaners, string, straws, trays, and a large container.

BUBBLE MAKERSINDIVIDUAL WANDSBend pipecleaner to form a circle, square, heart, and triangle.RECTANGULAR FRAMEMaterials: two standard drinking straws; a piece of cotton string 11/2m long. Procedure: Feed the string through both straws and tie a knot.TETRAHEDRONMaterials: Three standard drinking straws; three half-size straws; and nine pipecleaners. Procedure: Twist two pipecleaners together to make a pipecleaner that is somewhat longer than a standard drinking straw; repeat twice. Put three long pipe cleaners together and twist them together at the top. Slip three standard drinking straws onto the pipecleaners; bend the pipecleaners at the bottom to form feet. Insert three standard pipecleaners through three half-size straws. Make a triangle with them by twisting their corners together. Twist base and top together at corners.CUBEMaterials: Six standard drinking straws, each cut in half; and twelve pipe cleaners. Procedure: Put three of the pipecleaners together and twist them tightly at one end. Make four complete sets. Slip half-straws onto the pipe cleaner; bend the pipe cleaner to form feet. Make each set look like the capital letter T. Use two sets to form a square with two extended sides. Repeat the procedure with the other two sets. Make one square bottom of the cube by twisting up the extended straws; make the other square the top by twisting the down the extended straws. Fit the top to the bottom, twisting all corners.Strategy:

Cooperative Learning

1. Each student receives 4 pipe cleaners, a straw, and a cup.

2. Make a circle, square, heart, and triangle with a pipecleaner.

3. Cover the bottom of the cup with Dawn dishwashing liquid.

4. Fill the cup with a 1/2 cup of water.

5. Blow bubbles indoors and outdoors.

6. Record results on Bubbleology worksheet.

7. Form three groups.

8. Build a rectangular frame, tetrahedron, and a cube.

9. Record results on Bubbleology worksheet.

3. Draw and cut out a simple soap molecule. (Don't forget to draw circles

around the molecules.)

4. Paste the soap molecule on construction paper.Return to Physics Index

5. Discuss the simularities and differences between water and soap molecules.Performance Assessment:

Students are evaluated by completing the bubbleology worksheet and constructing

water and soap molecules . This assignment is graded as a pass or fail lab in

class assignment.Conclusion:

Regardless of the shape of the wand, bubbles always form spheres.Reference:Science and Children, May 1986Science Scope, October 1988AIMS Education Foundation, 1988
