Building  1.      When it was built. 2.      Who designed and built it. 3.      Where in the world it is located, continent, country and city (with a map and arrow pointing to location). 4.      Main construction materials used to build it. 5.      What type/category of structure is it AND explain how you known. 6.      Main internal forces. 7.      Main external forces. 8.      Explain whether it must support a static (dead load) and/or dynamic (live) load. 9.      Describe at least one major design challenges that were faced when designing and creating this structure. Explain how they were overcome. 10. Five additional interesting facts. 11. Images of: the design plans for the structure (if you can find them), the construction process and the final structure (at least two views). Show the s...

Introduction to Structures - Part 1, 2 & 3 / Hands-On Project Questions (Build Report)

Image
*Part 1 - Questions should be completed by Monday April 23. Show Mr. Mak when finished. *Part 2 - Questions should be completed by Monday April 30. Show Mr. Mak when finished. *You may not continue building your structures project unless these are finished first. Part 1 List the four BIG IDEAS for the unit. (p. 1) Define structure. (p. 4 and glossary) Define stability (p. 4 and glossary) List six ways structures can be classified (grouped/organized into categories) (p. 10) Define solid/mass structure. (p. 11 and glossary). Give four real-world examples of solid structures NOT shown in the textbook. What materials are larger solid structures often built out of? (p. 11) Define frame structure. (12 and glossary) Give three or more real-world examples of frame structures not in the text. What material are most frames for houses built from? (p. 12) What material are frames for larger buildings such as apartments, shopping malls built from? (...

Mixtures Unit Test - Study Hints

Image
*The test is on Thursday, April 12 *If you are absent due to illness or athletics it is your responsibility to arrange a make-up date with Mr. Mak as soon as possible -What is matter? What are its two key properties? -Main ideas of the particle theory -Classification of matter into pure substances - elements and compounds -Classification of matter into mixtures - homogeneous (solutions) and mechanical mixtures (heterogeneous) -Explain the difference between solute and solvent -Three ways to increase the rate of dissolving and why they work -Prove, using simple calculations, why smaller particles have increased surface area (see image below) -Explain the difference between dilute vs. concentrated solutions -Explain the difference between soluble vs. insoluble -Concentration of a solution (Xg/100ml) -How to read a solubility graph (the one we discussed in class is posted above) -Explain the difference between unsaturated vs. saturated vs. supersaturated solutions -Explai...

https://www.youtube.com/watch?v=M_DYQ4C9fVc Types of Solutions 1. Explain, in your own words, what an unsaturated solution is. Be sure to include the terms solute and solvent in your work. 2. Explain, in your own words, what a saturated solution is. Be sure to include the terms solute and solvent in your work. 3. Explain, in your own words, what a supersaturated solution is. Be sure to include the terms solute and solvent in your work. 4. Explain, in your own words, how to MAKE a supersaturated solution. Factors Affecting the Rate of Dissolving 1. List three factors that can speed up the rate at which a solute dissolves. 2. For each factor briefly explain why it speeds up the rate of dissolving.
