Basic math is very easy to create a question for (such as 2+2=?). So I will instead explain part of how I teach basic math to younger children.
Addition: Again addressing 2+2, I would ask the child how to count to 2 on their fingers followed by asking them to do so on their other hand. Then ask the child to count how many fingers they are holding up. Subtraction: Addressing 4-2, I would ask the child how to count to four, followed by asking them to count to two out loud. Then ask the child to count two of the fingers on their first hand, putting each finger down as they count it until they reach two. Then ask the child how many fingers they are left holding.
Name and describe one of the many ethically controversial psychological experiments.
One option: the "Little Albert" experiment. Scientists attempted to create an irrational fear for a young child through classical conditioning. They first placed a white rat in front of the child. Initially the child was not afraid of the rat, because he had no reason to. They then began causing a loud startling noise every time they presented the white rat to the child. After many times, the child began to fear the rat - or better said, fear the noise associated with the rat's presence. The study was successful in causing fear through classical conditioning.
What are some of the effects of the Industrial Revolution on the workplace?
As the Industrial Revolution progressed machinery became more advanced and more common, able to complete jobs that previously required craft skill. With this came the rise in unskilled labor, as learning to operate the machinery was a much quicker education than learning to create the products by hand. This was also the time in which women were slowly incorporated into the workplace.
