- 1What is the correct order for the scientific methodIt is Problem, Hypotossiess, Materials, Procedure, Observations, Analysis, Discussion, Conclusion
- 2What is ProblemIt is the question that will be awncerd with the expairment
- 3What is HypothesesIt is a prediction on the outcome of the expairment
- 4What is MaterialsThey are the Materials that are needed for the expairment
- 5What is ProcedureIt is the steps taken to perform the expairment
- 6What is Obeservation?This is where you write what you observed during the expairment. No inferences are allowed to be here
- 7What is AnalysissThese are the results for the expairment tipicly shown in a graph
- 8What is Discousion?These are paragraphs duscousiong your results where you draw conclusions and discuss sources of error and how you could make your expairment better
- 9What is Conclusion?This is where you state if your hypothesis was correct, what you learned and if your experiment was succesful.
- 10What is a qualitative observationare discribed observations that do not involve numbers. EX: it is blue, it was says tesla
- 11What is a quatitative observationit is an observation that invoves the use of numbers. EX: there are four
- 12What is inference?it is when you make educatied guesses about an observation. For EX: it looks old, it looks damaged
- 13Is the interaction between structures and forces is predictable true or false?true
- 14Not all sturctures have a purpose, ture or fulse?fulse
- 15What is functionit is the purpose of a sturcture
- 16what is formit is the physical apperince of a sturcture
- 17is a tree a human made or natural stucturenatural
- 18what we dream of, is that human made or naturalnone
- 19what about a sky skraperman made
- 20I tree wants to stay alive for a long time. (Function or Form)Fucntion
- 21A tree is very solid and stiff (function or form)form
- 22a skyscraper can survive winds of 400 KPH (function or form)function
- 23a skycraper's foundation is 4 stories deepfrom
- 24Static LoadThe dead weight (gravity)
- 25Dynamic Loadloads that can be changed and are not permanent
- 26What are the 3 types of structures?Solid, Frame, Shell
- 27solid surface and hollow interior, evenly distributed force, can be very lightweight, What am Ishell structure
- 28sloid interior and exterior, stronger when thicker, often very heavy, mostly made of materials that resist compression What am I?Solid Structure
- 29I am made with a combination and I need all of them to not fall down, all of the components are attached together, lighter and more flexible than solid structures, and don't have compression well What am I?Frame Sturcture
- 30what is torsionIt is a twisting motion
- 31What is tentionThis is when something is pulled at opiste direction from opisite ends
- 32What is compresionWhen something is pushing down on something else
- 33What is SheerWhen a force is applyed hard enough that it causes damage to a structure
- 34A perfect center of gravity leads to what?A more stable structure
- 35A wide base and narrow top lead to what?A more stable structure
