Misconceptions about sinking and floating phenomena are some of the most challenging to overcome (Yin 2005), possibly because explaining sinking and floating requires students to understand challenging topics such as density, force, and motion. Two scientific principles are typically used in U.S. science curricula to explain sinking and floating:…

In the atmosphere or on the ground, snow provides students with unique opportunities to discover winter weather patterns. Traditionally, when students study weather, it is limited to the collection of data one would see on a weather report. However, the interdisciplinary Students Synthesizing Snow data in Natural Objective Ways (SSSNOW) project…

Explosions and fires--these are what many students are waiting for in science classes. And when they do occur, students pay attention. While we can't entertain our students with continual mayhem, we can catch their attention and cater to their desires for excitement by saying, "Let's make rockets." In this activity, students make simple, reusable…

Several teachers from State College (Pennsylvania) Area School District became intrigued with helping their students better understand the science associated with a unit on air and aviation. In particular, they observed that students often encountered difficulty with abstract flight concepts, such as lift, thrust, and drag. Content issues became…

Model rocketry is one of the best ways to get students interested in the physical sciences. Following safety guidelines, rocketry can really turn students on to science and also help them understand the applications of theories and scientific principles (Newton's laws of motion, force, mass, projectile motion, etc.) they are learning. The study…

Activities involving concave rubber disks are utilized to illustrate the scientific principles of kinetic and potential energy. Provides teacher instructions and questions related to the activity. (MDH)
