A student wants to know if the number of lady bugs in the garden changes from winter to spring. What is the best way to investigate this?

• Ask other students to count the number of lady bugs they see on different days and compare the data.

• Look for information about lady bugs on the internet about the number of lady bugs observed in other schools.

• Find out which plants in the garden attract the most lady bugs and count the number of lady bugs near those plants every month.

• Observe and record the number of lady bugs in the garden every week from December to May.

Gael and Dona wanted to find out which material would insulate their teacher's coffee cup and keep the coffee hot for the longest period of time. They first wrapped her cup with bubble wrap and recorded the temperature of the coffee once every 15 minutes for 2 hours. They repeated the investigation, this time using newspaper instead of bubble wrap, but they got the same results for both materials.  
What could they do to make sure their results are valid?

• Repeat their experiment.

• Use teas instead of coffee.

• Use a different thermometer.

• Conduct their investigation in a colder room. 

Frogs use the sun to keep warm. Donavyn hypothesizes that his frog will prefer swimming in warm water. He places his frog on a block in the middle of the bathtub, and measures how much time the frog spends off the block during a ten minute period. He conducts the experiment under four conditions in the bathtub: no water, warm water, cool water, and room temperature water. In this experiment, which is the control group?

• warm water

• no water

• cool water

• room temperature water

Imagine that a scientist suggests that the size of an insect population depends on the temperature. What observations must this scientist use in order to provide evidence to support his or her claim?

• The scientist must observe the insect population only in water.

• The scientist must observe the insect population in the laboratory.

• The scientist must observe the insect population in different areas.

• The scientist must observe the insect population throughout the year.

Caperton wants to create an excellent science fair project for the school competition. In order for her project to be valid, which of the following must happen?

• The project must include his opinions

• The results must be based on evidence

• The project must prove his predictions correct

• The results must be based on personal opinion

Carl compared the water temperature in two beakers placed on different colors of paper. He found the temperature was higher in the beaker placed on dark paper.
