OUTREACH : 50-min. HANDS-ON WORKSHOPS : New! Bubbles All Around

Take a look at surface tension in this interactive, bubble adventure. Students will learn how to make and measure different bubbles.

Requests

• Large, flat tables
• Carpeted room preferred
• This workshop can be messy, please dress accordingly

Michigan Grade Level Content Expectations, Science v.1.09

• Measure the length of objects using rulers (centimeters) and meter sticks (meters). (P.PM.02.13)
• Demonstrate that water as a liquid takes on the shape of various containers. (P.PM.01.22)
• Measure lengths in meters, centimeters, inches, feet, and yards approximating to the nearest whole unit and using abbreviations: cm, m, in, ft, yd. (M.UN.02.01)
• Distinguish between curves and straight lines and between curved surfaces and flat surfaces. (G.GS.02.04)
• Demonstrate that non-magnetic objects are affected by the strength of the magnet and the distance away from the magnet. (P.PM.04.34)
• Classify substances by their chemical properties (flammability, pH, and reactivity). (P.PM.07.11)

New! Bubbles All Around Pre-visit Vocabulary

Adhesion: The property of molecules to stick to other types of substances. Water droplets adhere to other surfaces.

Circumference: The perimeter of a circle. The circumference is calculated as p * diameter where p is roughly 3.14..

Cohesion: The property for molecules to stick with like molecules. Water exhibits cohesive properties.

Diameter: The maximum distance across a circle. The diameter passes through the center and is equal to twice the radius.

Height: A measure of vertical distance from the base of an object to the peak.

Iridescence: The property of certain surfaces to change color depending on the angle of observation. This is due to refraction.

Professional Bubble Maker™: Frequently mistaken as a straw, though visually similar. A PBM™ is used for creating bubbles.

Radius: The distance from the center of a circle to the edge.

Refraction: The change in the direction of a light wave. Refraction frequently splits white light into a rainbow.

Surface Tension: The apparent "skin" on the surface of a liquid that resists and external force. In water, this is due to the cohesive properties of the molecules.

New! Bubbles All Around Post-visit Activity

Post-visit activities provide your students with an opportunity to review workshop-presented concepts and introduce related subjects. Below you will find a classroom extension activity and a list of suggested resources for further exploration. We hope that you enjoyed our Outreach Hands-On Workshop and we look forward to visiting your students again!
