• Plastic is more harmful to the environment than other types of trash.
• People do not realize that paper is easily recycled.
• People are more likely to litter with paper than other types of trash.
• Children are more likely to litter than adults.

(SC.8.N.1.1) Sean is planning an investigation to test which materials conduct electricity. To do this, he will set up a simple circuit using a battery, wire, and a light bulb. Then, he will complete the circuit with objects made from different materials and he will observe whether the bulb lights up. In this experiment, what is the outcome variable (dependent variable)?

• whether the bulb lights
• the strength of the battery used
• how bright the bulb glows
• the object used to complete the circuit

(SC.8.N.1.1) The following line graph tracks the average salaries of employees at a company. Which of the following observations about the information in the graph is most accurate?

• The average salary mostly increased between 2000 and 2008.
• The average salary mostly decreased between 2000 and 2008.
• The average salary increased every year between 2000 and 2008.
• The average salary mostly stayed the same between 2000 and 2008.

(SC.8.N.1.1) Caleb wants to know how salt affects the boiling point of water. What is the best way for Caleb to collect data to answer this question?

• Add 1 gram of salt to 1 liter of water and 10 grams of salt to a second liter; time how long it takes for each to boil.
• Bring 1 liter of water to a boil, then add 1 gram of salt and observe any changes.
• Add 1 gram of salt to 1 liter of water and leave a second liter free of salt; time how long it takes for each to boil.
• Add 1 gram of salt to 1 liter of water and time how long it takes for the water to boil.

(SC.8.N.1.1) Marissa wants to know which of four routes that she could possibly take on her walk to school is the fastest. Which of the following is the best way for Marissa to gather information to answer this question?

• She should take a survey of her friends to find out what they think is the fastest route.
• She should look on a map to see which route looks shortest.
• She should have four friends each take one route and observe who arrives at school first.
• She should walk each route herself at a normal pace and time how long each takes.
