Transcription

1 Inquiry Master 6.1A Cabbage White Butterfly Inquiry, Care, Preparation, and Maintenance Calendar This calendar lists the approximate number of days after laying the eggs on the soil of the radish plants that certain events in the life cycle of the cabbage white occur. It indicates approximately when students should make specific observations, how you should prepare for upcoming inquiries, and when students should conduct them. Teachers activities appear in italics. Day Inquiry 6.1, lay egg Eggs hatch. Eggs hatch. Eggs hatch. Observe strips on soil of Measure and condition of radish plants. record body radish leaves.

3 Student Sheet 6.1A (continued) Reflecting on What You ve Done A. List the three main body parts of an adult butterfly. If necessary, refer to the reading selection Introducing the Cabbage White Butterfly at the beginning of this lesson. B. Did you see all three insect body parts in the larva? Explain. C. According to the maintenance calendar on Inquiry Master 6.1B: Cabbage White Butterfly Inquiry, Care, and Maintenance Calendar, approximately how many days is it from the time the egg hatches until an adult butterfly emerges from its chrysalis?

4 Name: Class: Date: Student Sheet 6.1B Tracking the Growth of a Cabbage White Larva Directions 1. Write today s date in the first box under the heading Date. In the box below the first, write the date for 3 days later. Continue until you have filled all eight boxes. (For example, if today s date were December 4, you would put December 4 in the first box, December 7 in the box below, December 10 below that, etc.) 2. Circle the date box below where you think the greatest growth in length will occur. Explain why you picked this date.

6 Student Sheet 6.1B (continued) Answer the following questions A. During which period of time did you observe the greatest growth in length? B. Did you see a pattern in the rate of growth? Explain. C. How do you think the pattern in the larva s growth rate relates to the amount of leaf material it consumed? 98 STC/MS O RGANISMS FROM M ACRO TO M ICRO

7 Inquiry Master 6.1B Cabbage White Butterfly Inquiry, Care, and Maintenance Calendar This calendar lists the approximate number of days after laying the eggs on the soil of the radish plants that certain events in the life cycle of the cabbage white occur. Use it as a reminder of (1) when to make specific observations, (2) how to prepare for upcoming inquiries, and (3) when to conduct the inquiries. Day Inquiry 6.1, Eggs hatch. Eggs hatch. Eggs hatch.

8 Name: Class: Date: Student Sheet 6.2 Larva Food Preferences Directions 1. In the space that follows, list the procedure steps you will take to conduct your inquiry. List any materials you will need that are not in the materials list. 2. Make a chart, data table, or drawing to show the results of your inquiry. (continued) 100 STC/MS ORGANISMS FROM MACRO TO MICRO

9 Student Sheet 6.2 (continued) Reflecting on What You ve Done A. Which species of leaf (or other food) did the larva eat? How does this choice relate to where the butterfly lays its eggs? B. What did you observe in the frass of the butterfly larva? Explain. C. Refer to the reading selection Picky Eaters and list at least two factors that influence how insects choose their diets.

11 Student Sheet 6.3 (continued) 3. Prepare a bar graph showing the total number of drops of each color. Reflecting On What You ve Done A. According to your data, did the butterflies prefer one color of nectar over another? If so, which color? B. Did the photocopy of the butterfly droppings have any color of drops other than the original four colors? Explain why you think this happened. (continued) STC/MS O RGANISMS FROM M ACRO TO M ICRO 103

12 Student Sheet 6.3 (continued) C. What factors involved in the setup of the feeders and butterfly houses do you think needed to be controlled in the preparation of the paper with the different colors of drops? D. Refer to the reading selection The Delicate Balance of Life at the end of this lesson to learn about other organisms that depend on a specific type of food for survival. Explain how an organism s limited diet narrows its habitat choices. 104 STC/MS O RGANISMS FROM M ACRO TO M ICRO
