learnadmin — Fri, 28 Aug 2009 07:17:53 +0200

The teacher guides learners in investigating the relationships between the different trigonometry functions, and in manipulating the functions in order to show identities. After the lesson a panel of experts discuss issues raised by the lesson.

MC Maths 28: Trigonometry: Inverse Functions

learnadmin — Fri, 28 Aug 2009 07:17:53 +0200

The teacher guides learners in investigating the relationships between the sine, cosine and tan functions on the one hand and the inverse trigonometry functions on the other. After the lesson a panel of experts discuss issues raised by the lesson.

MC Science 25: Newton`s laws 2

learnadmin — Fri, 28 Aug 2009 07:17:53 +0200

Learners investigate aspects of Newton’s second Law. They represent projectile motion using vectors. They work out the force of attraction between two objects. A panel of experts discuss. This is suitable for FET science teachers.

MC Science 26: Newton`s laws 3

learnadmin — Fri, 28 Aug 2009 07:17:53 +0200

Learners distinguish between a force exerted on an object and an object experiencing a force. They also look at the difference between Newton’s Laws One and Three. A panel of experts discuss. This is suitable for FET science teachers.

MC Science 27: Work, energy and power

learnadmin — Fri, 28 Aug 2009 07:17:53 +0200

Learners use concepts of work, energy and power to investigate motion. They perform an experiment to look at the relationships between these concepts. A panel of experts discuss. This video is suitable for FET science teachers.

MC Science 28: Boyle`s Law

learnadmin — Fri, 28 Aug 2009 07:17:53 +0200
