Students will design and later build a measuring tool that can measure good vs. bad behavior that is not a scale.
1. Science and Engineering Practices: constructing explanations and designing solutions; Creativity & Innovation: critical thinking and problem solving;
2. Disciplinary Core ideas: Engineering
4th grade students think about the concept of a scale and design another measuring tool to present the same idea.
Before Rosh Hashanah students were introduced to the concept of the scale in Judaism that is associated with the high holidays. For homework, they were tasked to think about an idea for an alternative measuring tool that helps us to reflect on the past year.
Students bring various materials and/or use materials available in the lab including:
paper, pipe cleaners, wood, paint, duck tape, glue guns, cups, balloons, hammer, nails, screws, rubber bands, Popsicle sticks, recycled lids, toilet paper rolls, cardboard, straws, aluminum foil
What worked: Students were very engaged in the process of designing and building the measuring tool. The task required them to think critically about the concept of scale and judgement in an abstract way.
What didn’t work: The students did not have enough time in the lab and some of the products still resembles a scale.
What we might try next time:
We will give more time during planning for teacher’s feedback in order to avoid students making a measuring tool that looks and function as a scale.
