Expository Lesson Plan



Curriculum Standard: PHYSICAL SCIENCE

2. Identify properties of objects and materials, position and motion of objects, and properties of magnetism.
a. Classify properties of objects and materials according to their observable characteristics. (DOK 2)
• Materials (e.g., wood, paper, plastic, metal)
• Matter (solid or liquid)
• Objects that sink or float in water


Big Idea: Organize items and materials according to characteristics.



Preparation:

1. Show students some objects and ask them to name some things that are unique to that object.

2. Tell the students to pay close attention to the different objects. (Color, size, shape, and material they are made from.

3. After showing the objects introduce the term, characteristics and classify.

4. Discuss what characteristics are and how these can be used to classify objects.

5. Tell students that they will be making a semantic feature analysis to show how some objects can be the same or different based on their characteristics.

6. Show the students an example of a chart you have prepared before class.


Guidance:


1. Students brainstorm to think of some characteristics we might use to classify the objects.

2. Students will groups up and create a poster of the objects and how they classified them.

3. They will discuss why and how they chose what they did.


Application:

1. Use teacher Observation while the students are working.

2. Check to make sure they have classified all objects and can justify why.

Assessme:

The teacher will pick up the semantic feature analysis from each group and check to see that:

1. Check to see if they used the required number of items
2. That the features are relevant to the object they are working on.
3. That each feature that applies to the object is marked correctly.
