7. Table 1 Flower Species Pollen quantity (mg) per anther Anther quantity per flower Stamens covered with pollen (%) A4.81126 B7.91826 Certain species of flowers attract more bees than others with the scent of their pollen. The pollen is found on a structure within the flower called the anther, which is located on top of a structure called the stamen. Flowers typically have multiple anthers and stamens. Bees carry pollen from the flowers on their legs. The bees move from flower to flower collecting pollen. Some of this pollen falls from their legs. This depositing of pollen causes crosspollination to occur (fertilization of the other flowers). Three studies were conducted to study this process. Study 1 For two flower species (A and B), pollen quantity per anther in milligrams (mg), anther quantity per flower in number, and percentage of stamens covered with pollen were recorded (see Table 1).

8. Study 2 The researchers hand-pollinated flowers from a third species, Species C. They also observed the Species C plants being cross-pollinated by the bees in the area. All flowers were observed for 2 years. The scientists recorded the results in Table 2. Table 2 Cross-pollination of Species C flowersResults from: Hand-pollinated flowers Bee-pollinated flowers Flowers that reproduced 3011 Flowers reproducing after 1 year 933 Flowers reproducing after 2 years 714 Total flowers produced after 2 years 4539

12. Time (sec) Position (cm) 0.5042 1.0067 1.80106 2.50179 Students in a summer science class studied the motion of a battery-powered toy car. For the three experiments they conducted, the toy car was allowed to move freely across the smooth surface of a lab table. Experiment 1 During the first experiment, students measured the position of the 58 g toy car with 3 cm width wheels after it had moved in a straight line for different amounts of time. The data for this experiment is given in Table 1. Table 1 IVDV IV DV

13. Experiment 2 In the second experiment, students changed the mass of the car and measured its position after 1.50 seconds. The toy car’s wheels were 3 cm in width. The data for this experiment is given in Figure 2. Position (c m) Figure 2 IV DV

14. Experiment 3 Students altered the width of the wheels in the third experiment and measured the position of the 58 g toy car after 2.50 seconds. The data for this experiment is given in Table 3. Wheel Width (cm) Position (cm) 3108 4 5 6 Table 3 IVDV IV DV
