Card slider mechanisms

Levers and sliders: moving cards

Unit Summary

This unit develops pupils' knowledge of simple mechanisms. By making levers and sliders, pupils will apply their knowledge of the characteristics of paper and card to make their own moving cards.

Lesson Summary

You will learn to explore and create slider mechanisms using paper and card.

Key Notes

  • Mechanisms are systems that make something move and include sliders.
  • Sliders are rigid bars which move backwards and forwards along a straight line.
  • Sliders have a guide, which is used to keep it in place.
  • When constructing sliders, it is important to cut and measure accurately.

Vocabulary To Learn

  • slider: a bar which moves backwards and forwards along a straight line
  • guide: a piece of material used to keep mechanisms in place and control movement
  • slot: the hole through which a lever or slider is placed to enable movement

Common Mistakes To Avoid

  • Slider mechanisms have a pivot points.

3 Quick Questions (With Answers)

1. Explain the lesson in two key points.

Mechanisms are systems that make something move and include sliders. Sliders are rigid bars which move backwards and forwards along a straight line.

2. What does this key word mean in this lesson? 'slider'

a bar which moves backwards and forwards along a straight line.

3. Correct this common mistake.

Mistake: Slider mechanisms have a pivot points. Correction: Slider mechanisms do not have pivot points and therefore do not use split pins. Slider mechanisms use a guide and a slot. They move in a straight line, rather than turning or pivoting.
