1.)DAY ONE is to be used to decide which objects will be measured. DAY TWO is to be used to finalize projects and present findings. A third day can be used if necessary.
2.)Students will be placed in pre-arranged groups.
4.)Students are to use a digital camera to capture the pictures of taller items whose heights will be calculated. (e.g. flagpole, building, tree, telephone pole, etc.)
5.)One student in each group will stand next to the tall object. One student will take pictures. One student will measure the shadow lengths of the object and the person. Another student can record the measurements. As a group, the students need to decide what form of measurement should be used (inches, feet, centimeters, etc.) Several pictures should be taken.
6.)Once students have recorded information for 5 tall objects, they will return to the classroom to create a presentation.
7.)Students will determine the best way to present their information. They may do a PowerPoint presentation or use the pictures together with a drawn poster of their findings.
8.)Students must set up proportions relating the one student's height and his shadow's length to the object's height and its shadow's length. Students must decide how tall each object is, and the answers must be clearly stated for each object.
9.)Students should include other ways they can use this activity to calculate the missing length of similar polygons.
10.)The presentation can be graded using the attached rubric.
11.)As a wrap-up, discuss how this project can be used outside the classroom. Where do they anticipate using this knowledge again? Is it feasible to use in other subjects?
