Structures
What is the strongest shape in terms of structural stability?
Triangles
What are the groups that completely oppose Highway 413?
Indigenous people and environmentalists
What is a pure substance?
It's something made of only one type of element and has specific properties.
What is conduction?
A method of heat transfer through direct contact and friction. When a hot object touches a cooler object, the hot object's particles (which have a lot of energy) transfer to the cooler object's particles, heating them and giving them more energy. As a result of this, though, the particles of the hotter object lose energy, so they get cooler.
This question is worth 600, not 400, AND if answered correctly, your next question will have an additional x2 points if answered correctly. So with that...
What was the scavenger hunt slideshow we did in the structures unit called?
My Leo Baeck Structures Scrapbook
How does a cantilever bridge work, and why is it good?
It's a bridge suspended on one vertical beam. Since they can open and close, boats can go through, making it very efficient.
When will Highway 413 be created?
No specific date was ever given for its finish.
What are the first three elements on the periodic table? Also, today is your lucky day (if you get this BONUS question right). What is the atomic number of Martoshium? (+800 points if answered correctly)
First: Hydrogen
Second: Helium
Third: Lithium
Bonus: 777
What is the difference between heat and temperature?
Heat: The transfer of thermal energy from one object to another because of a temperature difference
Temperature: The average amount of kinetic energy in an object
What was the first thing ever posted in this Google Classroom?
Structure Stability
What are the four types of structures? Explain what they are.
Solid: A structure made of solid materials with very little space inside. It uses its mass to withstand forces.
Frame: A framework of beams that spread out force to each other, allowing them to be able to withstand a lot of force.
Shell: A hollow structure with a curve. This curve allows for the structure to distribute forces evenly, making it quite strong.
Combination: A combination of these three in one structure.
What are two possible groups that could collaborate during the Town Hall because they share similar views, issues, and problems?
Indigenous people and Environmentalists
OR
Environmentalists and Farmers
OR
Government and Construction crew
Explain the 5 components of the particle theory.
1. All matter is made up of tiny particles
2. All particles have spaces in between them
3. Particles in matter are constantly moving
4. Particles have bonds that join them together
5. Particles move farther and faster apart when heated, and the opposite when they're cooled.
What are the three types of heat transfer? Explain each of them.
Conduction: Heat transfer through physical touch
Convection: Heated fluids rise, and it gets replaced by a cooler, denser fluid that then sinks.
Radiation: Heat transfer without matter. It uses heat waves to transfer heat.
What was the description for the Heat Transfer Lab on Google Classroom?
Create a cover for a pop can so it loses as little heat as possible.
What is the thing called that allows a bridge to be protected by flowing water, debris, and ice?
Cutwater
What were the six different groups in the Town Hall?
Farmers, construction crew, government agency, environmentalists, indigenous people, and delivery services.
Describe how each element is laid out and formatted on the periodic table.
Middle: Symbol
Top left/right: Atomic Number
Bottom Middle: Name of the Element
Bottom: Atomic Mass
Which has more temperature: A giant iceberg or a campfire?
The campfire! It's TEMPERATURE, not heat!
Name the two assignments that were posted on February 5.
1. Particle Theory
2. Elements Form Compounds
Define the following terms:
Abutment
Three-hinged arch
Pile
Abutment: These are the things at the end of the bridge, which make it more stable and support it. They absorb most of the forces that go on the bridge. They act as retaining walls that prevent forces from the ground, like earthquakes, and stop the bridge from moving.
Three-hinged arch: Arches hinged at their bases and the middle. This makes the bridge more flexible, making it able to withstand expansion and contraction from extreme weather conditions.
Pile: These are structures that go vertically, which hold up a bridge. They can be made of steel, wood, or concrete. They’re hammered into the soil or dirt under the bridge until they hit the rocky layers. When the piles are hammered deep into the ground, the bridge becomes more stable because more forces are being sent towards the ground.
EVIL QUESTION (x2 points)
What were all of the reflection questions on the Highway 413 assignment?
1. How was this Town Hall like real life? How was it not?
2. How did you feel acting in your role? How does your role or perspective resonate with your own values?
3. Which group(s) did you most strongly resonate with? Why? Did your opinions change over the course of the Town Hall? Why or why not?
What two substances on the periodic table are liquids?
Bromine and mercury
Define the following terms:
Thermal equilibrium
Kelvin
Vacuum
Thermal equilibrium: When at least two objects touching each other reach the same temperature
Kelvin: A way to measure temperature that starts at absolute zero, or 0 degrees Kelvin
Vacuum: A space that has absolutely no matter within it
Aren't you a daredevil?
This question is worth infinite points. If this is answered incorrectly, you lose 2000 points. You may back out now, only for a price of 500 points. OR you can answer this question:
What did Mr. Martosh post on December 5? Be very specific with what it said.
It was a screenshot of the whiteboard saying:
Grade 7
Now that many of you are reaching the end of the video part... You Must (underlined) edit (boxed) your script for spelling, grammar, and meaning. Make sure each section answer is detailed (boxed) and connects (boxed) to the project and is 'formed' in science and design. Make sure you have some connection to the 6 factors (boxed) of the D rubric.
