CRASH TEST DUMMIES Practical 1 Inertia and seat belts
PLEASE ADD THIS PAGE INTO YOUR 'MOTION' ONE-NOTE NOTEBOOK ON YOUR COMPUTER Part A - Effects of Inertia TEACHER DEMONSTRATION[page 118 Science World 3]
• Set up the ramp as shown in the photo –but without the barrier.
• In your group -DISCUSS the 6 questions of the Part A discussion
• Write a sentence to outline what the experiment has shown.
Part B – Inertia and speed. this part will be written up as a formal experimental report
•
• Variables Identify the variables
(things that could change) in this experiment -
• How could the collision speed be more accurately determined?
[hint: use the average speed rule p104 -what do you need to measure?
• Hypothesis Write statements about what you predict will cause the landing distance of the plasticine to change
• Procedure [page 119 Science World 3 is your guide - method to be written in past tense and passive voice] use a 1 cm CUBE to represent the dummy (as shown in diagram)
What benefit do you think a cube would be over a physical dummy?
Results draw up a table with columns for the factor deliberately changed and each of the measurements made
• Discussion Questions Answer the 4 questions in the investigate activity
PLUS
Q5 In a real car crash, how many different collisions are there and how are they linked to the damage done?[text p119]
Conclusion: Write a conclusion about speed and inertia that links the different variables studied.
Study the accident data on the next 3 pages and answer the questions as part of your report REPORT Exercise 1
• The bar graph shows the number of people killed in car accidents at different times of day and different days of the week.
• What patterns and trends do you see in the data?
• What cause-effect links can you make as to the patterns and trends seen?
