The lever and pulley challenge

The meteorite is in a big hole - how will the recovery team get it out in order to retrieve it? Take a masterclass in levers and pulleys in order to send a brief to your forces on the ground.

Science Objectives

i) Explain that unsupported objects fall towards the Earth because of the force of gravity acting between the Earth and the falling object.

iii) Recognise that some mechanisms, including levers and pulleys, allow a smaller force to have a greater effect.

Working Scientifically

1. Plan different types of scientific enquiries to answer questions, including recognising and controlling variables where necessary.
2. Take measurements, using a range of scientific equipment, with increasing accuracy and precision, taking repeat readings when appropriate.
3. Record data and results of increasing complexity using scientific diagrams and labels and tables.
4. Use test results to make predictions to set up further comparative and fair tests.
5. Report and present findings from enquiries, including conclusions, causal relationships and explanations of and degree of trust in results, in written forms.
