This is the third activity in my Littlest Bits
unit. Use simple materials* to demonstrate the size of particles. Watch a video
for an overview of the lesson.
What is the liquid that was dripped into the balloon before it was inflated and sealed?
Students work in pairs, then groups, then share as a class how to figure out what liquid was placed in the balloon. It's a simple way to show the size of particles of vanilla using a balloon and student curiosity.
Students read about the activity in a student text
that has been saved in two reading levels, two different image types (blackline and color), and two languages (English and Spanish). Both texts have been recorded
for students who need to hear the information.
Choose from several options for extending or assessing
This lesson can be part of a unit to meet NGSS 5-PS1-1♦.
