Agricultural Engineering and 2nd grade

Second graders learned about pollination while they tested and built hand pollinators.  We read a story about a plant that would not produce its berries and discovered how important insects are to plants.  Then they tested different materials to see which would pick up and drop off "pollen" (baking soda).  After they did that, they designed the best shape and combination of materials for the most successful hand pollinators.  They built and tested their designs.  Some made adjustments after the test to make the pollinator more efficient.  It was really wonderful to watch them discover, build, test, and redesign until they were satisfied.  Here are some photos of the process.
