Experiment: Build your own airbrush – Applying Bernoulli
“Rapidly moving air will be at a lower pressure than when it is stopped. This is called Bernoulli’s principle. So when you blow across the top of the straw, the rapidly moving air is at a lower pressure than the air above the water in your glass.” https://www.thenakedscientists.com/get-naked/experiments/build-your-own-airbrush-applying-bernoulli

Teacher Tool Video: ETS1.B: Developing Possible Solutions
In this video Paul Andersen explains how many possible solutions are developed in the design process. As many solutions to the problem are identified using a brainstorming process. These solutions are compared to the specific constraints and criteria of the solution. Models are created to test the viability of each solution. A K-12 teaching progression…

Sketchpad: Hannah’s Lowrider
Cranky Contraptions are wood and wire kinetic sculptures that animate a character or scene when the handle is turned. One thing that I enjoy, is that this activity is an open-ended platform for expression. Recently an Explainer seized this opportunity to make a personally meaningful artifact through a cultural lens. As a facilitator, I want…

Experiment: Hydraulic Battle
Plunge into hydraulics with a pair of dueling syringes. Two different-sized syringes full of water are connected together. Push on one, and feel the force—multiplied—in the other. https://www.exploratorium.edu/snacks/hydraulic-battle

Experiment: Hydraulic Arm
You’ll feel the pressure to do some heavy lifting.When you push the plunger on a syringe, water is forced into a second syringe, extending its plunger and lifting a mechanical arm. The process illustrates aspects of fluid pressure, force, mechanical work, and biomechanics. https://www.exploratorium.edu/snacks/hydraulic-arm
