Environmental
This principle of science is the way we can use balloons or other objects to remove small particles from the air.
What is static electricity?
The study of forces and motion for objects in a fluid (air or water).
What is aerodynamics?
What is digging?
The movement of these free particles through conductors transmits electricity.
What are electrons?
This is the iterative process engineers use to create new inventions.
What is the Engineering Design Cycle?
On Monday, we discussed five different types of pollution. Name two of them.
What is Waste, Water, Air Light, and Noise.
These four forces work together to keep flying objects in the air. Name three of them.
What are lift, gravity (weight), drag and thrust?
This force, based on the density and surface area of an object, determines whether an object floats in water (or other liquids).
What is buoyancy? (What is buoyant force?)
Arduinos are this type of of technology because they require code to be uploaded to them in order to perform complex tasks.
What are microcontrollers?
There are multiple ways to get a fish over a dam or other obstacle. Name two that we discussed.
What is a fish highway, ladder, elevator and cannon?
There are three laws of physics that we use to explain how airplanes (and other flying devices) generate lift. Name two of them.
What are Newton's 2nd Law (Any mass accelerating generates a force), Newton's 3rd Law (For every action there is an equal and opposite reaction) and Bernoulli's Principles?
Adventures use there a six simple machines. Name three types.
What is the wheel and axle, the pulley, the inclined plane, the wedge, the screw and the lever?
There are four components in a typical circuit. Name three of them.
What are wires, switches, loads and power sources?
In order for a human to fly, they would have to flap their arms this many times per second.
What is 100?
This device is a lab machine that separates solids and liquids using density and centripetal force.
What is a centrifuge?
This type of software is often abbreviated to CAD and is used by engineers when they want to test or bring their designs to life in the virtual world.
What is Computer Aided Design?
Moats are an essential castle defense. Name two reasons that moats can help keep pesky adventurers and intruders off your castle's front porch.
What are: limiting attacker access (can't swim in armor), providing distance for defenders (all the better to shoot you from), creating difficult terrain (sometimes full of spikes) and occasionally full of wildlife?
This force is created as a results of the reference frame of a moving charge.
What is magnetism? (What is magnetic force?)
What are nurdles?
Parachutes are used to help slow falls by increasing the _______ of a falling person and lowering their ________.
What is air resistance and terminal velocity?
This type of Civil Engineer specializes in Earth materials, how they move and seismic events.
What is a geotechnical engineer?
This command is used in Arduino coding to transmit a voltage through a certain pin.
What is analogWrite?
