Tools of the Trade
This tool is used to measure the mass of a prototype in grams.
Scale / Triple Beam Balance
The metric system is based on this number, making it easy to multiply or divide.
What is 10?
You should always wear these to protect your eyes from flying debris or chemicals.
What are goggles?
This is the first step of the design process, where you figure out the problem.
What is define/identify?
There are this many centimeters (cm) in 1 meter (m).
What is 100?
To find the volume of a liquid for a cooling system, an engineer uses this marked glass cylinder.
What is a graduated cylinder?
This is the standard metric unit used to measure the length of a bridge or a race track.
What is a meter?
If a glass beaker breaks during a test, you should do this immediately.
What is tell a teacher?
After you "Create" a prototype, you must do this to see if it actually works.
What is test it?
There are this many millimeters (mm) in 1 centimeter (cm).
What is 10?
If you need to measure the thickness of a very thin sheet of metal, you would use this tiny metric unit.
What is a millimeter (mm)?
This metric prefix means "one-thousandth" (1/1000) of a base unit.
What is milli-?
This is the proper way to smell a chemical in the lab without inhaling strong fumes.
What is wafting?
If your bridge fails at 10kg but your goal was 15kg, you are in this phase of the design process.
What is test?
To convert 5 kilograms (kg) into grams (g), you multiply 5 by this number.
What is 1000?
The measurement of gravity's affect on your mass is called
What is weight?
Put these in order from smallest to largest: Kilometer, Millimeter, Centimeter, Meter.
What is milli, centi, base, kilo?
You should never do this with "leftover" chemicals or materials after an experiment is over.
What is return them to their containers?
These are the specific requirements or "rules" your design must follow to be successful.
What are constraints?
An engineer needs a 0.45 meter (m) wire. How many millimeters (mm) should they cut?
What is 450mm?
To find the volume of an irregular shape, you measure how much the water level rises, a process called this.
What is the displacement method?
One Liter (L) of water has a mass of exactly this many kilograms (kg).
What is 1kg?
Before starting a "Stress Test" on a prototype that might shatter or break under pressure, an engineer must establish a "Buffer Zone." Describe what a Buffer Zone is and name one piece of safety equipment (besides goggles) required for this specific type of test.
A Buffer Zone is a cleared perimeter around the testing area where no people are allowed to stand. Safety equipment could include a transparent blast shield (lexan/acrylic) or safety floor tape to mark the boundary.
During a project, you realize that your design is successful but your materials are too expensive, exceeding your Constraints. You decide to swap out a 20 cm titanium rod for a 200 mm steel rod. Identify which step of the Design Process you are in, and explain why this swap did (or did not) change the Criteria of the length.
You are in the Iterate phase. The length did not change because 20 cm is equal to 200 mm; you are simply optimizing for cost while maintaining the same physical dimensions.
Your prototype moved 25,500 millimeters (mm). How many kilometers (km) is that?
What is 0.0255km?
