G Problem solving

1.                  The block of ice (temperature 0°C) shown below is drawn over a level surface lubricated by a layer of water 0.10 mm thick. Determine the magnitude of the force F needed to pull the block with a constant speed of 0.50 m/s. At 0°C, the viscosity of water has the value of 1.79 x 10^-3 N·s/m².

The viscous force on an oil drop is measured to be equal to 3.0 x 10^-15 N when the drop is falling through with a speed of 4.5 x 10^-4 m/s. If the diameter of the drop is 5.0 x 10^-6 m, what is the viscosity of air?

Presentation

End

Students answer questions to check their learning of the objectives of the day. Teachers check the work done right away and give feedback. Teachers summarizes the main points of the lesson. Students listen and comment.

Students write the homework.

Differentiation – how do you plan to give more support? How do you plan to challenge the more able learners?

Assessment – how are you planning to check students’ learning?

Health and safety regulations

Differentiation can be by task, by outcome, by individual support, by selection of teaching materials and resources taking into account individual abilities of learners (Theory of Multiple Intelligences by Gardner).

Differentiation can be used at any stage of the lesson keeping time management in mind.

Use this section to record the methods you will use to assess what students have learned during the lesson.

Health promoting techniques

Breaks and physical activities used.

Points from Safety rules used at this lesson.

Reflection
