Instructions for AC/DC Clock Survey
This activity will get students up out of their seats polling the entire school (or as many rooms as you feel fit).
Goal: For students to find the percentages of each type of clock in the building and to find out which type, AC or DC is more common.
Each student will be given the worksheet below. You as the teacher will need to assign the students to a specific classroom (it works best if you send them in pairs: that way one can write and one can count/survey). The students will go to that class room and, without disturbing the educational work of that classroom, take a survey of the types of clocks that are in that room. You will need to stress to students how to be polite, quick and quiet when going to other rooms. Remind students to look for other clocks not mentioned in the survey (like copiers, microwave, phone on wall, etc.)
Once all the students return you will do the totals on the board. You can have each partner/group display their information. In the bottom table of the worksheet students will then use everyone’s data to complete it. They can show their work in the columns. To the right, they have 3 boxes to total ALL clocks, AC (plugged in) clocks, and DC (battery) clocks.
***Your students might bring up that fact that some clocks can be both…like laptops run on a battery and can be plugged in (same with cellphones) so you can decide as a class which to call those devices that can be both***
To tie in a cross-curriculum activity, the last row is for students to figure out the percentages of each type of clock in the building. (They may need an extra piece of scratch paper for this)
**I hope you students enjoy roaming the building. I even sent my students to the office and the principal’s office to survey clocks! You can get really serious and even do the kitchen, copier room or Teacher’s lounge. As long as you state clear expectations that they are not to go anywhere other than that room and to be very quiet in the hallways, it can be a really great activity!
