Learning Experience 8: Wood, Plastic, & Metal

TEACHER’S GUIDE

Materials:

For each pair of students:

2 Student Activity Sheets for Learning Experience 8

Wood (oak, mahogany, walnut, pine)

Plastic (clear, green)

Metal (aluminum, brass, steel)

Cardboard tray

Labels for wood, plastic, and metal

For the class:

9 large samples of each material

Preparation:

Read the background information in the Properties Teacher’s Manual. (Please see PDF) Provide each pair of students with a cardboard tray and an assortment of four different sample woods, two different sample plastics, and three different sample metals. Instruct the students to group the objects. Since these objects are the same size and shape, students will most likely group them by color, weight, or material. (Grouping by color or weight may be the same as grouping by material but the students may not realize this.)

Basic Skills Development:

Reading

Listening

Speaking

Testing

Observing

Comparing

Predicting

Evaluation Strategy:

For this learning experience teacher will provide wood, plastic, and metal labels, and distribute them to the students. Have each student attach a label to something in the classroom that is made of metal, plastic, or wood.

Vocabulary:

wood

shiny

aluminum

metal

oak

brass

plastic

mahogany

steel

grainy

walnut

acrylic

flexible

pine

Objective: Students will sort the objects by mass and color and determine that some objects are made from different materials and as a result possess different properties.

What materials are objects made of?

Use the large samples of wood, plastic, and metal to teach them the names of the materials they have. Tell them that wood, plastic, and metal are materials. List the properties of each material on the Student Activity Sheet for Learning Experience 8.

Discussion Questions:

How did you group the objects?

Which material is the heaviest/lightest?

How might the property of an object changed?

How might material be combined to create an object that has a new property?
