| Objectives |
|
| Materials and Activities | |
| Engage | Teachers will bring
in a variety of concrete samples made of various aggregates.
Students will begin a teacher-initiated discussion about what the pieces of concrete are made of. A brief history of port land cement is given by the teacher, with student giving examples of concrete structures they are familiar with, along the way. |
| Explore | Students will form groups to "hunt" for examples of concrete around the school campus. Each group will be assigned a different area of campus to prevent overlap. Each group will have a magnifying glass to observe their samples and will record their observations in a lab book. |
| Explain | Students will regroup
in the classroom to explain their findings to each other. Teacher will
help by inserting proper terminology to enhance the student's report.
Students will explain where on campus they found concrete and what it is used for. They will give a brief description of the make-up of the concrete. If time permits, the class might go to the different sights while the students explain. |
| Elaborate | Using information and terms previously learned, the students should be able to discuss why the concrete is made differently for different uses. They should get a feel for the use of different aggregates to perform specific functions and begin to realize that concrete takes on many forms. A discussion will continue on how to concrete into various forms/shapes. |
| Evaluation | Through all the discussions and newly learned information, teacher will be able to assess students' knowledge through questions about the difference between cement and concrete, how concrete is made, the usefulness of aggregates and the various uses for concrete. |
| Homework | Look around the house for examples of concrete. Be ready to share with the class how it is used, amount of aggregates, formability or flatness. |
