INTRODUCTORY ACTIVITY :
EXPERIENTIAL ACTIVITY
Teacher-Student Activities A. Warm-up Session
Begin the lesson by recalling the prior knowledge of students on the following topics:
- Surface area and volumes of cube and cuboid.
- Surface area and volume of cylinder and cone.
- Surface area and volume of sphere and hemi- sphere.
Recall the formulae to calculate the surface areas and the volumes of different basic solids.
Then, show different objects (or their images) that are made by the combination of different solids.
Teacher’s Explanation
Now teacher will provide complete explanations of all the formulas of the solid figures and ask the students to learn these formulas. Following solid figures need to be discussed here.
Surface area and volumes of cube and cuboid.
- Surface area and volume of cylinder.
- Surface area and volume of cone.
- Surface area and volume of sphere and hemi- sphere.
- Surface area and volume of Frustum of cone.
Combination of solid Figure.
Here we combine two or more solid figures and then find the surface area and volumes. Teacher will explain the method of finding the surface area and volume in the combination form.
Surface Areas and Volumes: Clay Activity
In this activity, students will calculate the surface areas and the volumes of the combination of solids.
In this activity, students with the help of clay make some solid figures and will calculate the change, if any, in the surface area and the volume of a solid when it is converted into different solid or multiple solids, either of the same or different shapes.
Explanation of the Activity
Divide the class into two groups. Bring some modeling clay to the classroom.
Ask a group to shape the clay in any of the basic solids, such as cube, cuboid, cylinder and sphere.
They need to take the required measurements and calculate the surface area and the volume of the solid that they have made.
Now, the other group should break the solid and make numerous smaller solids from the clay. Then, they need to take the required measurements and calculate the surface area and the volume of the smaller shapes.
Thereafter, ask both groups to analysis the relation between the surface area and the volume of the original solid and the new solids.
Conduct a similar activity to prove that when the shape of a solid object is changed, its surface area changes but the volume remains constant.
For this activity, change the original basic solid into the basic solid of a different shape.
For example, change a cube into a cylinder and compare the surface area and the volume of the cube with the cylinder.
Practice Work
Now teacher will explain the method of finding surface area and volumes by taking some examples from NCERT book. Teacher will also provide some questions to the students for practice
Practice with combination of solid figures
Teacher will also explain some other mixed problems [for the problems of combination of solid figures, not more than two solids be taken in combination] and should provide sufficient number of problems to the students for practice.
- Review questions given by the teacher.
- Students should prepare the presentation on the formulas of surface area and volumes of different solid figures.
- Solve NCERT problems with examples.
- Solve assignment given by the teacher.
Observation skill, analytical skill, critical & creative thinking, team work, constructive approach, interpersonal skill, engagement in learning process etc.
- Assignment sheet will be given as home work at the end of the topic.
- Separate sheets which will include questions of logical thinking and Higher order thinking skills will be given to the above average students.
- Class Test , Oral Test , worksheet and Assignments. can be made the part of assessment.
- Re-test(s) will be conducted on the basis of the performance of the students in the test.
