welcome NYSMTP! The STEM based projects & activities below can be found on this website. These activities are ones that can be done in a classroom, and may actually be applicable without the lean towards manufacturing. However, feel free to brows through and see what can be done if you want to work it into an engineering or technology based setting.

• Q & A: Mass properties in Onshape?
• Basic CAD Modeling & Math Activity
• Advanced CAD Modelling & Math Activity
• Statistical Analysis with M & M’s
• Statistics in Manufacturing
• Robotics & Calculating Roll Angles

Overview of HAB Project:

One of the most exciting projects, according to all of my former students, was the HAB, or High Altitude Balloon Project done in my Engineering Design & Development class. Looking back on it, it was one of the biggest challenges my students ever faced with the highest risk of failure as well, but with risk, comes reward. The view of the curvature of the earth on video was absolutely stunning!

Also in retrospect, this project required my students to apply more math and science concepts than any other as well.

• Math: One former student developed an equation to determine accurately how much helium to put in the balloon. This equation is used widely in HAB projects worldwide.
• 
• Earth Science: Tracking teams had to analyze weather data and other factors to determine where it would land: http://predict.habhub.org/
• Physics: Students had to determine forces on all parts to determine failure points in the project.
• Thermodynamics: Batteries do not work in low temps… how do you power it?
• Fluid Dynamics: How does temperature affect the size of the balloon? Elevation? What makes it go higher?
