Theactivities range in time from a few minutes to 1 – 2 class periods. These are mentioned below.Each section ends with text that expounds the concepts in the hands-on activities.The SectionsIn Section 1, an extra effort is made to engage students. There are three hands-on parts—eachwith the same theme but with very different materials:o A: applying a flame to steel in two forms: a nail and steel woolo B: adding water to a superabsorbent polymer in two forms: pellets and powdero C: dissolving in the mouth five forms of sugar

Theunsaturated solution had a low density of dots (sugar molecules dissolved in water) in the beaker(C). The saturated solution had a higher density of dots and also had a small mound of saturatedsugar sitting at the bottom of the beaker (B). The supersaturated solution had the highest densityof dots but there was no sugar sitting on the bottom of the beaker (A). A significant majority,78%, incorrectly chose beaker B as being supersaturated. The primary reason that was given wasthat there was excess solute (undissolved sugar) sitting in the beaker. This result is similar to theprevious one, with both studies having

This can be quite difficult to do in astandard lecture classroom model. With this insight into our students’ mindset comes theknowledge that college instruction needs to evolve and adapt. A move towards more learner-center classrooms has begun, with the focus on transitioning to active learning at the front.Figure 2: Learning Activity Categories and their Relative Student Engagement Level [1]Active

This type of question, as well as the pre-post scores for such a question from the MCI, are shown below.If a rod of metal is pulled through a tapered hole smaller than the diameter of the rod, thestrength of the metal in the rod increases. This is because:_______ a) the density has increased b) there are more atomic level defects present c) there are less atomic level defects present d) the bonds have been strengthened e) the bonds have been compressed Page 13.191.6

Course grade was used as the between groups variable and attendance was the dependentvariable.
