  1. Mariana Becomes a Butterfly By Danielle Carse and Kristy Costa

  2. Mariana's Story • Mariana's friend brought her a plant back from Hawaii • At first, the plant had berries • Eventually, they all fell off and it wouldn't grow berries • Mariana went into the garden to observe pollination between insects and plants • She noticed no insects were visiting her plant • The insects needed to pollinate the plant were not in the garden • Mariana created a pollinator to pollinate her plant so it would grow berries. • After several materials and supplies, it worked.

  3. Materials Used

  4. Create Two Flowers Flower A: • Cut out a flower shape from dark construction paper • Cover the center with a thin coat of baking soda for a flat flower, such as a poppy. Flower B: • Fill the bottom of a test tube with baking soda to represent a tube-shaped flower such as a Dutchman's pipe.

  5. Two Flower Types: Flower A (pink flower) OR Flower B (test tube)

  6. Popsicle Stick • Does not pick up any baking soda • Does not drop any baking soda

  7. Pipe Cleaner • Picked up some baking soda • Very little baking soda fell when tapped

  8. Pom-Pom Ball • Has a larger surface area • Picked up more than the pipe cleaner • Dropped a lot, but still held on to some

  9. String • Picked up a very little amount of baking soda • Cannot be seen because both are white • Dropped a little.

  10. Tape • Picked up only a thin layer of baking soda. • Because of the sticky surface it didn't release any baking soda either.

  11. Aluminum Foil • Picked up a tiny bit of baking soda, covering only a thin layer. • Like the tape, it did not drop any baking soda.

  12. Our Pollinator Creation: • Glued a pom-pom onto the end of a pipe cleaner • We expected it to be the best possible pollinator for both types of flowers • There is a lot of surface area and depth to reach down in the longer test tube

  13. Critique • We feel that the original activity is not very student friendly. • There is not much critical thinking involved in the original activity. • The activity does not seem very interesting for younger kids so we wanted to add in a little more interactive aspects.

  14. Alternate Activity • Children go on a nature walk to observe the flowers • They get to see how they are actually pollinated before taking part in a similar activity.

  15. Which Flower is Best? • After the nature walk, children can use whichever of the original two flower types that they think they know more about. • If a child saw more flat flowers then he or she could choose to use a flat flower to experiment with.

  16. Next, the groups will decide which materials they will try for their hand pollinator. • There will be 12 materials laid out and they are to choose which 4 they want to experiment with. Choices: Pipe Cleaner Pom-Pom Balls Popsicle Stick String Tape Aluminum Foil Thin Paint Brush Paper Duct Tape Wax Paper Pencil Straw

  17. Predict: • Make a prediction of the best pollinating material. • Explain why that material is the best. • This allows for critical thinking.
