Jamie is explaining to her classmates that she conducted an experiment over the weekend to see if adding more eggs to a cupcake recipe would affect the taste and texture of her cupcakes. She told her classmates that she noticed her cupcakes are moist and even taller. She said she measured each cupcake and the ones made with 3 eggs instead of two were 0.25-.05 centimeters taller than the ones with only 2 eggs. She also said that the ones with more eggs seemed to be a darker shade than the ones with fewer eggs. Jamie said the amount of eggs did not affect how many cupcakes she could make. She was only able to get 6 jumbo sized cupcakes with the recipe even if she added an extra egg. Question: List at least 2 qualitative and 2 quantitative observations that Jamie made in her experiment.
qualitative: moist, darker, texture, taste
quantitative; taller (with data), number cupcakes made
In Jamie's cupcake experiment, she made both qualitative and quantitative observations. Here are at least 2 examples of each:
Qualitative Observations:
1. Jamie observed that the cupcakes made with more eggs were moister. This qualitative observation describes the attribute of moisture, which cannot be measured in precise quantities.
2. Jamie observed that the cupcakes made with more eggs appeared to be a darker shade. This qualitative observation involves comparing the visual appearance of the cupcakes to determine their relative darkness, which is a subjective assessment.
Quantitative Observations:
1. Jamie measured the height of the cupcakes and found that the ones made with 3 eggs were 0.25-0.5 centimeters taller than the ones with only 2 eggs. This quantitative observation involves measuring the exact height difference between the cupcakes using a ruler or measuring device.
2. Jamie discovered that adding an extra egg did not affect the number of cupcakes she could make, as she was only able to produce 6 jumbo-sized cupcakes regardless of the egg quantity. This quantitative observation involves counting the exact number of cupcakes produced and determining that it remains constant regardless of the variable being tested (number of eggs).
