Hooke’s Law And The

Elastic Behaviour of Springs.

Mass On A SpringLearning Intention

We are learning about how: i. To measure, record and

describe the relationship between extension of an elastic object (i.e spring)

and the force applied. ii. To use data to plot a graph

and calculate the spring constant k.

Starter ActivityYou have 4 minutes to draw a sketch

of how you will set up the equipment to find how the stretch of

a spring changes with mass

Helping you investigate!Before you start your practical work, think

about:

i. How you can make your test fair?

ii. How you can make your test safe?

iii. Can you predict what will happen?

iv. Can you explain your prediction?

v. How many observations or measurements will you make?

vi. What range of values will give a suitable result?

i. Should you try out some tests to check your ideas

before writing down your final plan?

ii. How will you record your results clearly and

accurately?

Learning Objectives

Must be able to…Record results in a table

Should be able to…Take accurate measurements of stretch

Could be able to…Plot a graph of results

Explore Carry out the experiment, and record your results in

a table

Independent VariableMass in gNo more than 700g!

Dependent VariableStretch of spring in cm

1. How did you make your measurements accurate?

Explain

2. What is the relationship between stretch of the spring and mass?

3. How could you use this equipment to find the mass of your pencil case?

ExtendWhat graph could you use to show

your results? Can your result be shown on a bar chart or a line

graph?

What are the steps needed to draw a line graph?

Plot a graph of your results. Can you see a pattern in your

results? Does your result support your prediction?

Calculating your gradient

What is spring constant?

Can you calculate spring constant from

your graph?
