Students will be perplexed and engaged as they figure out how big COULD they blow a bubble in one breath? Lots of student involvement. Low-floor, high-ceiling. Lots of fun!
Goals: By the end of this lesson, students will have practiced using the formulas for the volume of a sphere and volume of a cylinder, and they will have practiced solving literal equations. This includes solving equations with fractions and cubes. They will also have a better understanding of the meaning of volume, by means of visualizing cubic centimeters, and cubic inches.
I hope your students like it and it helps them feel more confident in solving equations, and in thinking about volume. Let me know how it goes in your classroom in the comments, and how did you make it BETTER?
Materials needed: Bubbles (or a youtube clip of bubbles, but real ones are cooler), Rulers, Balloons and/or Chewing gum.
Optional: cubic centimeter block, cubic inch block, measuring tape (in case students want to measure circumference instead of estimating diameter using a ruler), student phones (to record video/pictures).
