| 5th grade students were given a math exam after different amounts of sleep. One group slept 7 hours or more, and the second group slept fewer than 7 hours. The students had similar skills in math. They ate the same meals the previous day. The exam score was measured and the results show that students that slept 7 hours or more scored better on the exam, while students who slept less than 7 hours scored worse. What is the manipulated variable in this experiment? | one group slept 7 hours or more and the second group slept less than 7 hours |

| Is this statement an inference or an observation: The child block is orange. | observation |
| Is this statement an inference or an observation or both: The street is wet, so it must have rained | both - you can observe that it is wet and make the inference that it rained |
| Is this statement an inference or an observation: The table looks like it is made of wood. | inference - it has the look of wood, so you draw that conculsion (or infer) that it is wood |
| What is true of all observations? | They must involve the use of at least one of the human senses. |

| Students wanted to determine if the length of string affected the clearness of sound in a telephone made with string and two tin cans. The students used different lengths of nylon string and various sizes of tin cans. What should the students do to improve this experiment? | Use the same size of tin cans so that the length of the string is the only thing that is diffenerent |
| Jan and Justin want to know if there is any difference between the braking distance from bicycle tires from two different manufacturers. Justin will put one brand on his bicycle and Jan will put the other brand on her bicycle.
