This demonstration is one that I have been using for years as part of a lab on Newton’s Laws. The lab involves a series of demonstrations in which each demonstration is described and students are asked to make a prediction. After the demonstration is performed, students are asked to record their observations and connect the demonstration to one of Newton’s laws.Over time I realized that one demonstration was sufficient to achieve a deeper understanding of Newton’s laws if students were provided the time to investigate using the dimensions of the NGSS to explain the phenomenon. The result is this lab investigation, Hanging By A Thread.A good place to start is by having students recite Newton’s laws of motion; a simple task. Then the teacher would present a simple motion demonstration (i.e. releasing a balloon) and ask students to identify, citing evidence, which of Newton’s laws were demonstrated; not so simple. Encourage students to argue from , but let students ponder the responses. Hopefully, more than one law is presented. Tell the students you will return to this question. Introduce the BLOSSOMS video and begin.
