Are you sitting down as you read this? Are you sitting completely still? While certain objects, like your chair, for instance, might seem at rest, everything in the world is really in constant motion; all matter in this universe is packed with atoms that vibrate with energy. Matter is anything that has mass and takes up space. So, why does your chair stay still beneath you with all that atomic energy? And why does a ball move if you kick it? Over years ago, physicist Sir Isaac Newton set out to answer these questions about forces and motion.

One of the most difficult things to teach middle school students is how to ask meaningful and thought-provoking questions. Using the ABC Activity Before Concept method of science inquiry teaches students to write, use, and answer testable questions. From the experiences in Elicit, students generate a list of testable questions in order to design and conduct experiments that will help to seek answers to selected questions about the same topic. During the Explore phase of the inquiry model, students are provided with experiences that cause them to recognize the inadequacy of their current understanding to set the stage for new learning to occur. Various teacher-designed or student-designed activities are used to develop correct understanding of the topic during the Inquire phase.
