Which technology is really the best? Does it meet all the criteria of the challenge? Second graders are closing out their geotechnical engineering unit, comparing the technologies they designed to prevent wind erosion. Way to go second grade!
Second graders continue to improve their technologies to release water onto their farmland. They are recording the data from their experiments to show other groups how successful their design was in meeting the criteria of the challenge. Our highest number of squares to be reached on the farmland was 86 out of 90! The student pair to design the technology used a swinging mechanism to distribute the water a farther distance! How neat!
