- The bundle opens with a PhET-fueled simulation lab activity that I used as a precursor to an in-class, hands-on experiment involving carts and motion tracking (not included here).Next we have an in-class (in-Zoom?) direct instruction activity fleshing out Newton's Second Law via a series of fanciful$11.99$15.94Save $3.95
This demonstration uses the operation of a blowgun as a tool to review Newton's laws of motion. A marker pen is blown at high speed through an aluminum tube. Inside the tube, the marker goes from being at rest to traveling well over 50 miles per hour. It flies through the air a short distance at nearly constant velocity before being stopped by a cardboard box.
In each phase of the motion (tube, air, and box), students are asked how each of Newton's laws are relevant. They are not to recite the text of laws, themselves, but to apply them to the situation at hand.
A presentation of observations is linked to in the student document. This in-class demo was modified for use in remote teaching/distance learning (RT;DL). Here's what I wrote about it on my Blog of Phyz at the time.
