5 Topic Life cycle of butterflies Key Question How can you use a model to better understand the life cycle of a Painted Lady butterfly? Learning Goals Students will: make a model of the Painted Lady butterfly s life cycle, create a graph that shows the time span of each part of the cycle, and read and decode information about the life cycle. Texas Essential Knowledge and Skills for Science 4.10C Explore, illustrate, and compare life cycles in living organisms such as butterflies, beetles, radishes, or lima beans 4.3C Represent the natural world using models such as rivers, stream tables, or fossils and identify their limitations, including accuracy and size Math Graphing bar graph circle graph Science Life science animals life cycles Integrated Processes Observing Comparing and contrasting Identifying Relating Materials For each student: Stage Time rubber band book #19 rubber band life cycle wheel activity pages For each group of students: pasta (see Management 1) 4 cups, 3-oz white glue Unifix cubes in four colors (see Management 2) crayons tape Background Information A Painted Lady butterfly goes through a complete metamorphosis. The four stages are the egg, the caterpillar (larva), the chrysalis (pupa), and the adult butterfly. The focus of this activity is to give students the opportunity to make a model and create a graph that will show the relative time spent in each of the four phases. Data were used to create a cycle of 50 days; however, Painted Lady butterflies may have a cycle more or less than this length of time. Management 1. You will need to purchase small boxes of orzo, large shell, spiral, and bowtie pasta. Place the pasta in the cups for each group of students to use. 2. The color of the Unifix cubes does not matter. Each group will need four different colors. Give each group about 25 of each color. Not all Unifix cubes will be used. Unifix cubes (item number 1919 or 1928) are available from AIMS. Procedure 1. Ask the Key Question and state the Learning Goals. 2. Distribute the Stage Time rubber band book and direct the reading of the book. 3. Discuss the information in the book. Have students identify the four stages of the life cycle of the Painted Lady butterfly. 4. Distribute the strip page. 5. Direct a discussion on each of the four stages. Have the students construct a bar graph with the Unifix cubes. 6. When the students have constructed all four Unifix cube trains, have them cut out and tape together the strips. Direct them to color the strips to match their trains. Core Curriculum/Texas AIMS Education Foundation

6 7. Distribute the Life Cycle Wheel page. Have students wrap the strip into a circle and place it on the circle graph. Show the students how to divide the wheel into the sector parts indicated by the colored strips. Make a circle graph showing the life cycle of the Painted Lady butterfly. Life Cycle Wheel e y.

8 Painted Lady butterflies are some of the most common butterflies in the world. Their favorite spots to live are near meadows with flowers. They also like mountaintops. Inside the chrysalis, a complete change takes place. The caterpillar changes into a butterfly. This change is called a complete metamorphosis. 2 7 The Painted Lady butterfly pushes itself out of the chrysalis. Its wings are soft and folded. The tired butterfly rests. It unfolds its wings to dry. In a few short hours, it will fly off. It will look for a place to lay eggs to begin the cycle again. 8 7 Core Curriculum/Texas AIMS Education Foundation

9 The Painted Lady butterfly begins life as an egg. Adult females lay eggs on plants. Each egg is about the size of the head of a pin. The butterflies know the types of plants that the baby Painted Lady caterpillars will want to eat. Thistle plants are some of their favorites. The eggs hatch and come out Painted Lady caterpillars. The Painted Lady caterpillar eats and eats and eats. It spends almost its entire time during this stage of its life eating. As it eats, its skin gets tight. When this happens, the caterpillar sheds its skin. A Painted Lady caterpillar sheds its skin four times before it stops growing. 4 5 The third stage is where the biggest change happens to the Painted Lady. The caterpillar finds a safe place on a plant. It attaches itself so that it can hang down. Then the caterpillar s skin splits from its head to its abdomen. The green case that comes out is called a chrysalis. The Painted Lady butterfly goes through a four-stage life cycle. You will be reading about the changes the Painted Lady goes through. Pasta on a graph will model each of the four stages. This graph will help you learn more about the Painted Lady s life cycle. 6 3 Core Curriculum/Texas AIMS Education Foundation

10 The Painted Lady butterfly goes through a four-stage life cycle. You will construct a bar graph that shows the amount of time spent in each stage. You will then use pasta to represent what the Painted Lady butterfly looks like in each stage. Egg An adult Painted Lady lays her eggs on a plant. The eggs will take about four days to hatch. Use four Unifix cubes to show this stage. You will use orzo pasta to model this stage. Caterpillar (larva) A Painted Lady caterpillar spends more than two weeks of its life cycle eating. Use 16 Unifix cubes to show this stage. You will be using spiral pasta to model this stage. Chrysalis (pupa) A Painted Lady stays more than a week in this stage. Use nine Unifix cubes to show this stage. You will use large shell pasta to model this stage. Adult Butterfly An adult Painted Lady spends the next three weeks finding a place to lay eggs so that the cycle can begin again. Use 21 Unifix cubes to show this stage. You will use bowtie pasta to model this stage. Core Curriculum/Texas AIMS Education Foundation

11 Cut out the strips. Tape them together to make one long strip. (Be sure you put the tape on the back.) Color the strips to match your Unifix cubes. Go in order from egg, to caterpillar, to chrysalis, to adult butterfly. Cut out the strips. Tape them together to make one long strip. (Be sure you put the tape on the back.) Color the strips to match your Unifix cubes. Go in order from egg, to caterpillar, to chrysalis, to adult butterfly. Core Curriculum/Texas AIMS Education Foundation
