Activity no. 1.3: Exploring Newton's Law of Motion

*Balloons of various shapes


and sizes


*Construction paper


*String


*Straws


*Tape


*Scissors


*Kitchen clips


*Normal paperclips, crafting


sticks or other items that can be used as weights on the balloons


*Anchor points - could be


chairs, tables or even people


holding the string


*Stop watch


*Fabric tape measure or you


can use string and measure


the string


1. First, set up the anchor points about 10 feet apart. When selecting your anchor points, choose ones that can be easily moved.


2. Thread your string through a straw, and then secure the string to the two anchor points. Leave lots of slack so you can change the distance as required.


3. Attach your balloon to the straw using tape. For each challenge simply release the balloon to start it racing.


4. Change the distance between the anchor points until the balloon no longer reaches the end. What is the farthest the balloon will travel? Mark that point or record the distance.


5. Using a fabric tape measure or a string, measure the circumference of the inflated balloon. Now race it and record the distance it traveled. For the next race change the circumference making it smaller or larger.


Q1. How does it affect the distance traveled? Record the results.


6.Set your distance to the minimum the balloon travels. Now vary the circumference and use a stop watch to measure how fast the balloon travels the distance.


Q2. Does varying the circumference, and therefore volume and pressure in the balloon, the speed?


Record the results.


7. Keeping the circumference consistent, change the mass by adding paperclips, tape, paper, etc. to the balloon. Then race the balloon and measure the distance.


Q3. How does it compare with greater mass? Record the results.


8 Repeat the experiment but measure the speed of the balloon.


Q4. Does mass affect the speed the balloon travel? Record the results.



9. If you have different shaped balloons test how the shape of the balloon affects the results.


Q5. Does a long skinny one work better than the traditional oval balloons?


10. Try to keep the number of breaths used to blow up the balloons consistent to ensure the volume of air in the balloons does not change.


06. Measure distance and speed to see how the results differ.

Q7. How can you apply force to change the speed and direction of the balloon?

Exactly what is your question? This is a lab procedure. Collect the materials and follow the steps. If you have problems with any of the steps and/or related questions, ask the specific question.

Exactly! Note that the balloon must be taped to the straw such that: 1) the exhaust of the balloon (as it deflates) pushes the balloon and the straw, along the string horizontally; 2) The attachment of the balloon allows it to be blown up and to deflate without becoming disattached or changing orientation; 3) Please give some forethought as to exactly at what attachment point(s) along the straw and the balloon will allow the thrust of the balloon to glide the apparatus smoothly along the string! 4) Note that the tautest string provides the best path. If you have time, collect some data to show this! You will need a means of controlledly tightening the string: a variable mass tretching the string down over an edge will provide this. Remember to sketch your set-up, with relevant geometry, etc. shown! --Cheers, -Mr. d.

All right, the original comment has been screened. Let's try again, in pieces. Piece 1: Exactly! Note that the balloon must be taped to the straw such that: 1) the exhaust of the balloon (as it deflates) pushes the balloon and the straw, along the string horizontally; 2) The attachment of the balloon allows it to be blown up and to deflate without becoming disattached or changing orientation;

Piece 2AA 3) Think beforehand of the attachment points. The ballon + straw need to move smoothly along the string.
