Lesson plan example for ShowMe

  **Lesson plan for using iPads in science classes**  **Objectives:** students will use ShowMe iPad app to demonstrate their understanding of a variety of topics taught in all levels of science classes.  **Materials:** student iPads, teacher IPad, Apple TV, projector  **Procedure:** 1. Instructor will have previously demonstrated ShowMe app to students. 2. Students create their own ShowMe as a formative assessment of content learned in science class. . Examples: • 9th grade science - graphically explain the relationship between the frequency and wavelength of a wave. Identify the parts of a wave (peak or crest, trough, node, wavelength. Explain how the frequency and period of a wave are related. <span class="s5" style="color: #000000; font-family: Helvetica; font-size: 12px; font-weight: normal; line-height: 14px;">• Biology - draw a Punnett Square for a cross between a tall flowering plant with frilly flowers, and a short plant with plain flowers. Being tall is an autosomal dominant characteristic. Having frilly flowers is a recessive characteristic. What % of flowers will be tall and frilly? What % of flowers will be short and frilly? What % of flowers will be tall and plain? What % of flowers will be short and short and plain?  <span style="background-color: #ffffff; display: block; line-height: 1.2; margin-bottom: 0px; margin-left: 9px; margin-right: 0px; margin-top: 0px; text-align: left; text-indent: 36px;"><span class="s5" style="color: #000000; font-family: Helvetica; font-size: 12px; font-weight: normal; line-height: 14px;">• Chemistry - given a chemical equation: NH3 + O2 ---> NO2 + H2O, draw out the molecules using different colors for different atoms, then balance the equation graphically, adding reactant and product molecules as needed until the same number of each type of atom is present on both sides of the equation. Verify that there are equal numbers of the atoms of each element on both sides of the equation. <span style="background-color: #ffffff; display: block; line-height: 1.2; margin-bottom: 0px; margin-left: 9px; margin-right: 0px; margin-top: 0px; text-align: left; text-indent: 54px;"><span class="s5" style="color: #000000; font-family: Helvetica; font-size: 12px; font-weight: normal; line-height: 14px;">• Correctly balanced eqn is 4NH3 + 7O2 ---> 4NO2 + 6H2O <span style="background-color: #ffffff; display: block; line-height: 1.2; margin-bottom: 0px; margin-left: 9px; margin-right: 0px; margin-top: 0px; text-align: left; text-indent: 36px;"><span class="s5" style="color: #000000; font-family: Helvetica; font-size: 12px; font-weight: normal; line-height: 14px;">• Environmental science - draw a diagram which illustrates how point-source pollution (say lead from waste car batteries in an old dump) can move through the environment, be taken up by plants, be concentrated in the tissues of herbivores, and be concentrated even more in the tissues of predators. Be sure to illustrate how the toxin level increases at each stage. <span style="background-color: #ffffff; display: block; line-height: 1.2; margin-bottom: 0px; margin-left: 9px; margin-right: 0px; margin-top: 0px; text-align: left; text-indent: 36px;"><span class="s5" style="color: #000000; font-family: Helvetica; font-size: 12px; font-weight: normal; line-height: 14px;">• Astronomy - draw an H-R diagram, clearly labeling both axes. Draw the main sequence. Label the regions where the following 5 kinds of stars are located: small cool stars, large diameter cool stars, small hot stars, large diameter hot stars, a medium sized main sequence star like our sun. If the stars listed above have names for their types, give those names. Also, give an example of each type of star, if you remember them. <span style="background-color: #ffffff; display: block; line-height: 1.2; margin-bottom: 0px; margin-left: 9px; margin-right: 0px; margin-top: 0px; text-align: left; text-indent: 36px;"><span class="s5" style="color: #000000; font-family: Helvetica; font-size: 12px; font-weight: normal; line-height: 14px;">• Physics - draw a vector representing a force pulling parallel to the ground with a magnitude of 50 N. Draw another vector with the same origin, but representing a force pulling vertically upward with a magnitude of 20 N. graphically determine the direction and magnitude of the resultant vector. Show how you would calculate the magnitude of the resultant vector. <span style="background-color: #ffffff; line-height: 1.2; margin-bottom: 0px; margin-left: 0px; margin-right: 0px; margin-top: 0px; text-align: left; text-indent: 0px;"> **Assessment** <span class="s5" style="color: #000000; font-family: Helvetica; font-size: 12px; font-weight: normal; line-height: 14px;"> - have students show or email their ShowMe's to the instructor. Each ShowMe will be assessed for accuracy in presenting the indicated prompt.
