Activity 7: Creating Models of Bean Plants
Activity 7 - Teachers Pages
Your group’s task is to create a model that explains what
you are thinking about how a bean gets its food to begin to grow. Use ideas from your experiment!
This model will show how something works that we cannot really
see. We will use the model to imagine what is happening inside of the bean seeds.
Models can take many forms. We will put our model in the form of
a skit that your group will create and perform.
Work in your group to create a skit model that shows that you
understand how the embryo gets its food and that you can support your ideas with evidence.
Here are the rules for this model creation:
_____1. You must use all the following words: Food, energy,
embryo, seed, cotyledon, evidence
_____2. You must have each person in the group speak at least
once.
_____3. You can only use the props your teacher provides.
_____4. Your skit must be scientifically accurate based on our
experiment.
_____5. End with one idea about how the food gets into the
cotyledon and one question that you are wondering about.
Presenting the Skit Models
Watch each skit carefully and think about how good of a model it
is. How well does it represent what you think is happening inside bean seeds? Models can never represent
things 100% accurately. So think about ways in which each model is and is not scientifically
accurate. You will write feedback for each group on the chart. And you will have a chance to share your feedback
after each group’s presentation.
