Monocots and Dicots
In this lesson students set up a side-by-side germination experiment of monocot and dicot seeds. They will observe differences and similarities of these two types of flowering plants at the germination level, specifically the number of cotyledons. Students can record their findings daily. This is a great way to begin a flowering plant unit
Begin the lesson by providing students with a brief discussion on the two types of flowering plants – monocots and dicots – and how at their most basic, the difference is the number of cotloydens they have.
Use the student fact and observation sheet attached to help explain a cotyledon.
Break students into pairs and provide each group with a bag, seeds and three cotton balls.
Students moisten the cotton balls with water until they are wet, but not dripping
