## VOLUME

**
Purpose To introduce students to the measurement of volume with the graduated cylinder and the plotting of information on a graph.
**

**
Goal Upon completion of this exercise, 95% of the students will be able to measure objects accurately using the graduated cylinder, graph these results and predict results of other volume measurements using the same materials from a graph.
**

**
Procedures
**

- 1. Homework assignment—Lab from Cebco text or make up activity for reading a meniscus.
- 2. Oral evaluation of assignment.
- 3. Practical:
- ____ a. Have 2 graduated cylinders set up at each lab station. One with a known amount of liquid and the other without any liquid.
- ____ b. On an index card have the correct volume recorded then then invert the card. The student will then write the volume on a piece of paper, invert the card and check his/her answer. if having a problem, individual help will be given.
- ____ c. On an index card, write the amount of liquid to be placed into the cylinder. Check results and give individual help if needed.
- 4. Have students set up a graph with number of marbles vs volume of marbles.
- 5. Find the volume of 1-3-5-7-9 marbles and plot this information on the graph.

**
Evaluation
**

- 1. Have the students predict the volume of 2-4-6-8-10 marbles. from the graph.
- 2. Have the students find the volume of 2-4-6-8-10 marbles.
- 3. Have the students find the percent error which should be less than 3%.
