DESIGNING A HAND POLLINATORBy: Michelle Garcia and Erin Barrett
STORY COMPREHENSION In Mariana Becomes a Butterfly, Mariana
realizes that her Ohelo plant is not being pollinated by insects. She tells her dad about this problem. He then tells her to ask her aunt, an agricultural engineer, for advice. Her aunt uses the engineering design process to guide Mariana in finding a solution. In the end, she realizes that she needs to make a hand pollinator, so she does.
THE ENGINEERING DESIGN PROCESS
MARIANA’S ENGINEERING PROCESS Ask: “Why is my plant is not doing well?” Imagine: “ What are some reasons why my
plant is not being pollinated?” Plan: “ What types of materials will pick up
and drop off pollen well?” Create: “ Let me see test the materials.” Improve: “ Which material picks up and
drops off pollen the best?”
TRY IT! choose a type of flower design it Test various materials to see which would
pollinate a flower the best choose the best type of material to design
the hand pollinator Build the pollinator
OUR ENGINEERING PROCESS Ask: “ How can we design an effective hand
pollinator?” Imagine: We visualized how each material
would pick up pollen. Plan: We picked the materials we would test. Create: We designed some different hand
pollinators. Improve: We determined which materials
made the best hand pollinator, and then we combined these 2 materials to make a better hand pollinator.

IMPROVEMENTS This project would be an age appropriate
project for 2nd to 5th grade students. However with children in 1st grade or below,
the project would have to be simplified For example, you could have the kids test
less materials or have the teacher do the project as a demonstration
