Answer:
Answers below
Step-by-step explanation:
a) Why are the pancakes not coming out correctly?
b) A possible solution he came up with was to use eggs.
Hypothesis: Using a certain amount of eggs will make the pancakes come out correctly.
c) He incrementally increased the eggs (the control variable) until he had the correct amount, first starting with one and then finding out two had the pancakes come out well. He then tried three eggs to see if more was better and found that was not the case. He then tested other amounts of eggs.
d) After testing many different amounts of eggs, he decided two was the best.
e)
a: Emma's dad is wondering why his pancakes are not coming out the way he intended them after trying out a new recipe.
b: I predict that using eggs will make the pancakes come out correctly.
c: Emma's dad started out with a single egg, then increased it by a small amount to two, then to three. He then increased the amount of eggs by two for several other trials.
d: The hypothesis was true; two eggs saved the pancakes.
e: A possible error was how Emma's dad was inconsistently in how many eggs he was increasing the amount by; after initially only increasing the amount by one, he then began increasing the amount of eggs used by two.
f) A new question might be to test the number of eggs for numbers that he skipped. For instance, testing four eggs after skipping directly from three to five.
