John has 27 marbles. He gives them away evenly to 3 friends. How many marbles does eacch friend get?
27/3=9 We know this because 3+3+3+3+3+3+3+3+3=27 and we added 9 times. We could also guess and check with multiplication, figuring out that 3x9=27.
How would you describe classical conditioning?
Classical conditioning is a form of learning. In this type of learning, two types of stimuli are connected. A conditioned stimulus (CS) is associated with an unconditioned stimulus (US) to create a conditioned response (CR). The CR is a learned response to the US. Pavlov's experiment is a great example. Dogs salivate around food. Pavlov rings a bell when the food is presented. The salivation is the CR to the food and the food is the US (salivation around food is a normal response). Pavlov then rings the bell without the food and the dogs still salivate. The bell has become the CS. It is not normal to salivate when you hear a bell, but the dogs have associated a bell with food.
What is the difference between "there", "their" and "they're"?
"There" is describing a place. An example of this would be, "let's go over there". "Their" implies ownership. An example would be "Let's go to their house". Lastly, "they're" is a contraction for "they are" so you would use that one the same way if you were saying "they are". An example would be "they're so kind". There, their and they're are examples of homophones; they all sound the same but have different meanings.
