STEM 101
What force keeps objects pulled toward Earth?
Gravity
I design and improve engines, robots, manufacturing equipment, and machines. My work focuses on how things move and how forces affect them.
Mechanical Engineering
What does CPU stand for?
Central Processing Unit
What type of bond forms when atoms share electrons?
covalent bonds
Which Black agricultural scientist developed hundreds of uses for peanuts and promoted crop diversification in the American South?
George Washington Carver
An object has a mass of 10 kg and accelerates at 3 m/s². What force is acting on it?
30 N
A manufacturing facility needs to reduce harmful emissions, treat contaminated water, and comply with environmental regulations. I develop solutions to address these problems.
Environmental Engineer
Repeat a set of instructions
What happens to the pressure of a gas if its volume decreases while temperature remains constant?
Pressure increases
Who was the first Black woman to travel into space?
Mae Jemison
If the radius of a pipe DECREASES while an incompressible fluid flows through it, what happens to the fluid's velocity?
It increases, it speeds up
I design devices and technologies that interact with the human body. My work could involve artificial limbs, diagnostic equipment, implants, or other healthcare technologies.
Biomedical Engineer
What does RAM provide a computer with that allows it to temporarily store data being actively used?
short term/temporary memory
What type of electromagnetic radiation has a shorter wavelength: ultraviolet or infrared?
ultraviolet
Who was the famous Black mathematician who worked at NASA and helped calculate spaceflight trajectories?
Katherine Johnson
If the wavelength of a wave doubles while its speed remains constant, what happens to its frequency?
It is cut in half, halved, reduced by half
I work with reactors and other systems where extremely high temperatures and controlled reactions are used to produce useful energy. Safety, shielding, and controlling the reaction are major parts of my work.
Nuclear Engineer
A computer system divides a large problem into smaller tasks that can be processed simultaneously by multiple processing units. What computing concept is being used?
parallel processing
What does the first law of thermodynamics state
Energy cannot be created or destroyed; it can only be transferred or converted from one form to another.
What famous Black scientist developed techniques that helped improve the production of blood plasma?
Charles Drew
Explain Isaac Newton's three laws of motion
A process requires two substances to react, but increasing the temperature improves the reaction while also creating unwanted products. I determine operating conditions that maximize the desired product without compromising safety.
Chemical Engineer
A computer stores frequently accessed data in a small, extremely fast memory location so the processor can retrieve it more quickly than from main memory. What is this memory called?
cache
What process describes a solid changing directly into a gas without becoming a liquid first?
sublimation
Which Black inventor developed the traffic signal patent that improved the design of the three-position traffic light?
Garrett Morgan
