2018 Lesson #1 Vortex cannon & waves

4 domains of science

I am changing up how I am teaching science this year. I will be teaching the four domains of science according to the NGSS which are: Physical Science, Life Science, Earth & Space Science,  & Engineering/ Tech/ Applications of Science. We will be learning about all of these and how to use the cross- cutting concepts while doing experiments.

This lesson we will be learning about PS4 A: Waves and their applications in science and PS2: Motion and stability

In lab we will be making our own vortex cannons and learning what makes the air move, describing the characteristics of air and all of the different waves. We will look for patterns and also the structure and function of the vortex cannon.

An air vortex cannon works primarily by applying force quickly and efficiently to air molecules contained in a semi-enclosed space. When the stretchy balloon surface at the back of the cannon snaps forward, it collides directly with air molecules, accelerating them towards the opening of the cannon and setting off a chain reaction of high-speed collisions with other air molecules and the sides of the cannon’s barrel. The only way for all of these colliding high-speed air molecules to escape is out through the opening at the end of the barrel. The rapid escape of the air molecules forms a stream, or jet, of air that flows straight out of the cannon. Poof!

It’s going to be awesome! It’s about to get crazy in here. We are “blasting” into a new year full of science experiments- wahoo!!!
