My Students

Our students live in Oklahoma City. Our school is very diverse racially as well as economically.

The diversity of our students and the empathy they learn to show one another is what I enjoy most about our school.

They learn from me and I learn from them.

Problem solving skills and thinking skills develop a lot at this age (middle school). Teaching STEM to reinforce math and science content through problem based learning engages students and significantly benefit their academic achievement.

My Project

Medieval war machines that once inspired fear now inspire awe and interest in students. After learning about the history of medieval siege machines, students build and experiment with trebuchets. Students build and use a trebuchet to learn about relating speed with projectile mass, testing elasticity, and designing to make the trebuchet a mobile mechanism and to launch a projectile the greatest distance.

With this siege machine using counterweights, students explore how projectile mass affects a launch and how to calculate potential energy.

Then, they are challenged to use their knowledge to adjust projectile and counterweight masses in order to hit a target.
