Materials: leaves, magnifying glass, flowers, Bristol board ,computer

Previous knowledge: Students know the basic parts of a flower.

Objectives: Students will be able to:
1. identify parts of the flower
2. tell the difference between monocots and dicots
3. group plants according to leaf type and characteristics and present findings in a table form by using a computer.

Concepts:
Flowering plants include two main groups:
a) monocots
b) dicots

monocots

Monocot is the short for monocotyledon, which means that the seeds of these plants contain only one cotyledon or seed leaf.
Examples of monocots are: onions, bananas, tulips, wheat, barley, maize and daffodils.
Characteristics:
-all grasses are monocots
- Monocots have one cotyledon.
- Flower parts are in threes of multiples of three.
- Monocots have leaves with parallel veins that run down the length of the leaf
- pollen grains often have one pore.

Dicots
- two cotyledons
- Flower parts in fours or multiples of fours or fives.
- Leaf veins form a net pattern
- Pollen grain often have three pores.

Skills:
Observe different types of leaves and flowers.
Write the name of the different groups of plants

Form students into groups. Set on the desk of each group various different leaves, seeds, and flowers. Give students a diskette which will guide them into identifying the difference among the different items in front of them.

Development:
Ask for feedback from students. Have student present their findings orally. . Clear any doubts about the two groups of plants.

Conclusion:
Students will demonstrate their understanding by constructing table on Microsoft word and insert information.
