Beans Lab
Variables:
Independent variable: the mass of the beans
Dependent variable: the different types of beans
Control: The beans
Purpose: The purpose of the lab is to find equal measurement of each type of bean. After you find the mass of each bean you need to find the relative mass of each bean. The navy bean will have the smallest relative mass. You will need to wear safety goggles and a lab apron and wash hands after the lab is finished. If you drop any beans pick them up immediately to prevent anyone from slipping.
Materials
Safety goggles navy beans
Laboratory apron kidney beans
Graduated cylinder, 50- or 100 mL pinto beans
4 beakers, 150-mL lima beans
Wax marking pencil 4 paper cups
Funnel laboratory balance
Procedure 1. Put on your safety goggles and lab apron. 2. With marking pencil, label each of the four beakers: navy, kidney, pinto, and Lima. Attain a sample of each type and take it back to your station. Using a graduated cylinder, pour 17-20 mL of navy beans, 55-60 mL of kidney beans, 35-40 mL of pinto beans, and 110-115 mL of lima beans into their respective beakers. 3. Label each of the four paper cups with the name of one variety of beans. 4. Measure the mass of each cup and record the value in your Data Table. 5. Count out 60 beans of each variety and place them in their respective cups. 6. Measure the masses of your cups with their contents and record these values in your Data Table. 7. Return each kind of bean to its original container. 8. Clean up your work area and wash your hands before leaving the laboratory.
