elastic behaviour of springs and mass on a spring
DESCRIPTION
Elastic Behaviour of Springs examines the principle of physics that shows the physical relationship between extension and force needed to extend and or compress a spring as stated by Hooke's law.... --- Ivan Ukiwah (ConnectTeachers-UK)TRANSCRIPT

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?

Explore
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

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?

Extend
Can you suggest any further work to extend your
investigation?
Can you comment on any improvements you could make to:
i. the way you did your testii. the reliability of your result
