Maya designed an experiment to answer the following question:

How does the amount of water given to a lima bean seed affect how tall it grows?

In this experiment, what variable should Maya CHANGE? What is her independent variable?

• the amount of water

• the kind of plant

• the type of soil

• the amount of sunlight it gets

Klaus wanted to find out how the amount of sunlight affects the growth of plants. She placed a single tomato plant in 6 identical 10-inch pots with the same amount and type of potting soil. Each plant received ¼ cup of water each day.

3 plants were placed under a cardboard box and 3 plants were placed in the sunlight. She measured the growth of the plant each week for three weeks.

What is the dependent (responding) variable?

• Using the same type of plant

• Each plant was placed in a 10 inch pot

• The growth of the plant

• 3 plants in the sunlight and 3 plants under a box

Which of the following is a controlled variable? There may be more than one answer.

How do you calculate the median for a set of data?

• Add the numbers in the data set together and dividing the sum by the number of data pieces in the set.

• Place the numbers in the data set in order from least to greatest and find the middle value. If there is an even number of pieces of data, find the numerical average of the two middle values.

• Place the numbers in the data set in order from least to greatest and identify the number (or numbers) that occur most frequently.

Which of these organisms are not eukaryotes?

• Yeast

• Algae

• Fungi

• Bacteria
