Biology: Spring Break SOL Review Questions 1-102

For his science project Marquis wanted to know if temperature would affect the speed at which students complete homework. Marquis asked 20 students to complete a set of math problems in a room that was 15C. He then asked the same students to complete a similar set of math problems in a room that was 55C and then in a normal temperature room of 24C. Marquis timed the students for completion and then corrected each assignment.

What was his independent variable?

• math problems

• students age

• room temperature

• completion time

A student investigated the effect of radiation on the germination of bean seeds. Three hundred seeds were soaked in distilled water for one hour. They were then divided into three groups (100 seeds per group). One group was placed in a microwave oven on high for three seconds. Another group was microwaved on high for six seconds. The last group was not microwaved. The seeds were then planted in three separate flats and given the same amount of water. The flats were placed in a location with a constant temperature of approximately 27 degrees Celsius. Each day for two weeks the number of seeds that germinated in each group was recorded.

Which of these was his independent variable?

• Time microwaved

• Not microwaved seeds

• number of seeds germinated

• temperature

A student investigated the effect of radiation on the germination of bean seeds. Three hundred seeds were soaked in distilled water for one hour. They were then divided into three groups (100 seeds per group). One group was placed in a microwave oven on high for three seconds. Another group was microwaved on high for six seconds. The last group was not microwaved. The seeds were then planted in three separate flats and given the same amount of water. The flats were placed in a location with a constant temperature of approximately 27 degrees Celsius. Each day for two weeks the number of seeds that germinated in each group was recorded.
