A pillar can only hold so much ____ on top of it before it breaks?
What is Mass or Weight
100
The important thing to add when creating a hypothesis is ____ you think that one object will hold more than the other
What is the Why of a hypothesis
100
An object that is cylinder in shape and is used to hold up bridges and buildings
What is a Pillar
100
The gravel on the playground would not a good place to experiment pillars because?
The ground is too unstable
100
When testing cylinder pillars did the one large pillar or four smaller pillars hold the most weight? Why?
What is the four smaller pillars. The weight was able to be equally distributed across the pillars and it was more stable.
200
Why would using a square truss be the least stable?
There are no triangle shapes added to create support to keep the structure from collapsing
200
The final part of a Fair Test is your _____?
What is Conclusion
200
An object that is shaped like a horse shoe or half circle that is used to stabilize bridges
What is an Arch
200
If you do not include the "why" in your hypothesis would it be a good quality prediction? Why?
No, because it is an incomplete prediction
200
What was the best pillar shape to use? Rectangle, triangle or cylinder and why?
What is Cylinder, there were no folds in the paper and the weight was equally distributed
300
What shape helps stabilize structures?
What is the triangle
300
Your prediction of an experiment
What is Hypothesis
300
Box girder, rectangular, accordian _____
What is a beam
300
Would you add 20g, 100g or 500g first when testing the stability of an object in your experiment? Explain your answer.
20g would be the best one to use because you would not be able to see how much an object can actually hold if you start with larger weights.
300
What was the best connector used for the straw cubes?
What is the clay
400
If you were building a roof truss would you use some big triangles or more smaller triangles?
What is the smaller triangles. The more triangles the more stable the roof
400
This is the element that makes a fair test fair
What is the fact that you can only change one thing (variable)
400
What do you need to always include in your fair test question?
What is ALL the objects you are using to experiment with (Example: Will the rectangular, cylinder or square pillar hold the most weight)
400
If you wanted to test the strength of a beam would you step on it, cut it or start with smaller weights and see when it will collapse?
What is starting out with smaller weights
400
What is the best connector used for the toothpicks and why?
What is the play doh because it was the most stable and firm object.
500
You have created a question, hypothesis, observation and conclusion, what is the one section you are missing in your science write up?
What is the one thing that will change. (Example: We will change the shape of pillar we use, keeping the weights, cardboard, pillar material and surface the same)
500
The part of a fair test in which you draw your observation
What is a diagram
500
What two connectors used in the straw cube experiment work the least? Why?
What is the paperclips and pipecleaner. They were unstable objects, unlike the clay
500
Why would an accordian beam not be the best beam to use when building a bridge?
The accordian beam is too heavy and too bumpy to use
500
What was the best Truss used?
What is the truss with four triangles on each side
