Engineers and designers select materials which have properties that are best suited for an intended purpose. Students will continue their investigation of materials science by exploring properties of matter, including flexibility, hardness, strength, and absorbency. Students will apply this knowledge to a design problem involving the dispersal of seeds across a large area.
As students prepare for the design problem, they will learn about pollination, seed dispersal by animals, and seed germination. Students will also learn how nature has inspired product design, including the invention of VELCRO® brand fasteners. This popular hook-and-loop fastener was developed by a Swiss engineer after observing how burrs, or tiny seeds covered in hooks, became attached to his dog while on a walk.
Students will be introduced to the design problem through the three fictional characters who are planting a wildflower garden at their school. Baldwin students will be faced with the problem of how they will quickly and efficiently disperse wildflower seeds in a corner of Baldwin's property.
This is the third of three modules second grade will complete this year. This module will take place every day during the students' science time from April 23rd-May 17th. However, the students will be integrating their science with technology, engineering, math, and language arts. They will also be using the Innovator Skills of collaboration, communication, critical thinking, creativity, and problem-solving throughout this module.
