Regents Earth Science: Engineering Challenge

As part of our earthquake unit, I had my Earth science classes try to build “earthquake” resistant structures out of toothpicks and masking tape.  Different groups had different substrates to build in – dry sand, wet sand, or dough – to model the effects of different types of ground on building stability during earthquakes. From … More Regents Earth Science: Engineering Challenge

Elementary Physical Science: Building Vehicles and Teamwork

One of my favorite units for elementary school students is Motion and Design by STC.  I took quite a few photos during the last lesson of the unit when I taught it last spring.  I particularly like how the photos illustrate the collaborative nature of the work that the students did.  This represents a major … More Elementary Physical Science: Building Vehicles and Teamwork

Middle School Physical Science: Culminating Activity for Density Unit

I used this lesson as part as a middle school physical science class.  The curriculum STC/MS Properties of Matter provided the main structure for the class.  This particular lesson is not part of the curriculum; it’s an addition that I wrote because I felt that the density unit would benefit from the presence of a … More Middle School Physical Science: Culminating Activity for Density Unit
