7th Grade Final Exam REVIEW
1. You must be able to convert in the metric system.
- 1000g = ______kg
- 12L = ______mL
- 100cm=______m
2. What metric unit do we use for distance, mass, volume, density, speed?
3. What is an independent variable, dependent variable, and control variable?
4. ID the independent, dependent, and control variables in the following experiments:
- A researcher was interested in the effects of reward on intrinsic motivation. Some children were told that they would be given a special award for drawing with magic markers (an activity they already enjoyed). Other children were simply asked to draw with the magic markers. One week later, the children were unobtrusively observed for how much time they spent drawing with the markers. The children who expected and received a reward for drawing with the markers were less likely to draw with them later.
- In an investigation of the fundamental attribution error, subjects were given a speech to read that either favored or opposed Fidel Castro, the communist leader of Cuba. Subjects were told that the speech was written by a student who had been assigned to the position taken in the paper (that is, the student writing the speech had no choice on which position to take). Nevertheless, subjects believed that the student who wrote the pro-Castro speech had positive attitudes toward Castro, while subjects who read the anti-Castro paper believed the writer had negative attitudes toward Castro.
- A group of college students were given a short course in speed-reading. The instructor was curious if a monetary incentive would influence performance on a reading test taken at the end of the course. Half the students were offered $5 for obtaining a certain level of performance on the test, the other half were not offered money.
