Science Week 2013: Levers

We love Science! We have been celebrating a very special Science week in our bilingual Science lessons. We have been creating simple experiments following the scientific method. Year 6 has been investigating about levers.

Question: The aim of the investigation is to find out how levers work.

Materials: 2 pencils, a ruler, some heavy books, a ball pen and this worksheet.

Hypothesis: What do we think? We formulate our hypothesis. We still don’t know that there are many examples of levers around us and we use them almost every day.

Method: Try to pick up the book using your fingers. Get a ruler, a pencil and a book. Use the pencil as a fulcrum. Place the book on one end of the ruler. Push down on the opposite end while varying the distance of the fulcrum. If you don’t have a ruler or the ruler is fragile try with a pencil instead.

Record: We record the results of the experiment using a table.
We vary the distance of the fulcrum. Does our effort increase or decrease as the fulcrum moves closer to us?

Conclusion:

  • It is very difficult to lift a heavy book without a lever.
  • When we use a lever to lift a book the effort decreases.
  • The effort decreases if the fulcrum is close to the book.
  • The effort increases if the fulcrum is far from the book.
  • A lever decreases the amount of effort needed to lift the book.
  • A lever helps us to push, pull or lift things.
  • A lever is a simple machine very useful.
