This week in River Class


This week's Big Fish


What's new in Design and Engineering?

River and Sky students have been:
  • Making predictions about which materials and properties of materials are good or poor choices for a hand pollinator design.
  • Conducting controlled experiments to observe and describe the efficacy of materials for picking up and depositing "pollen."
  • Analyzing and comparing results of the experiments to inform decisions about their hand pollinator design.

Science concepts taught include:
Different materials have different properties.
Pollination is the reproductive system by which many plants produce new seeds.
Pollination can be accomplished by wind, insects, other animals.
Flowers have specific structures with specific functions. 




Students were able to see which materials picked up and dropped off pollen the best.

They will use this information as they develop their hand pollinators in the next step of this unit.
