Year 8 Assessment

2 Tasks

You work for a company that makes bungee cords. People jump from a platform on the top of a crane with the cord attached to their feet. It is very important that the people buying the bungee cord know how the cords stretch.

The company has made two new types of bungee cord:

Surefire and Bounce safe.

You have asked for the cords to be tested, and the results have come back.

Now you need to work out how to present the results so that people who want to buy a bungee cord can choose the right one for their situation.

Task 1

You need to design the text and pictures for a website that advertises the bungee cords for the company. You must present the data in a way that:

• gives the customer confidence that you have tested the cords
•  helps the customer choose the most appropriate bungee cord.

You need to Create two tables, and a single graph, comparing the two. Copy and fill in the tables as bellow

Surefire

Information

Data from the testing experiment

Force = 0 N

Surefire: length = 5.0 m, 5.1 m, 4.9 m

Bouncesafe: length = 10.0 m, 10.2 m, 9.8 m

Force = 200 N

Surefire: length = 8.0 m, 7.8 m, 8.2 m

Bouncesafe: length = 17.4 m, 16.6 m, 17.0 m

Force = 400 N

Surefire: length = 13.3 m, 12.7 m, 13.0 m

Bouncesafe: length = 30.5 m, 31.0 m, 27.5 m

Force = 600 N

Surefire: length = 22.0 m, 21.8 m, 22.2 m

Bouncesafe: length = 44.2 m, 45.3 m, 42.5 m

Force = 800 N

Surefire: length = no data

Bouncesafe: length = 48.2 m, 47.1 m, 45.7 m

Bouncesafe

Task 2

You need to write a report for your boss about the bungee cord testing. Your report should include:

• A presentation of the data.
• Recommendations for further testing based on the data.

Write a conclusion summarising the results. State which cord you feel is the best and which your would recommend to customers. Explain the positives and Negatives about each cord.

Include some suggestions for testing based on the data.
