Going Buggy!

Grade Level: Second

 

Brief Summary of Unit:

Second graders will explore the world of insects.  This multi-disciplinary unit consists of many hands-on and cooperative learning activities.  Through these activities, the students will gain an awareness for the many types of insects including those that are helpful, harmful, and social.  The students will also learn the distinguishing characteristics of an insect and the life cycle, metamorphosis.

 

Lesson One: Catching Their Attention

Objectives:  Students will realize what is necessary to raise a painted lady butterfly.  Students will recognize a butterfly’s needs.  Students will be introduced to the world of insects.

Activity:  During fall registration, each student will receive a painted lady butterfly larva.  Explain that we’re going to be studying insects, and they will be responsible for raising, researching and releasing this butterfly.

Assessment:  Teacher will use classroom observation to determine if the students are properly caring for their butterflies. 

Materials: painted lady butterfly kit from this site: http://www.earthsbirthday.org for students to observe the life cycle of a butterfly;

 

Lesson Two/Daily until Butterflies are Released: Raising, researching, releasing

Objective:  Students will realize what is necessary to raise a painted lady butterfly.  Students will translate the importance of a butterfly’s surroundings to its development.  Students will recognize a butterfly’s needs.  Students will reflect on removing a butterfly from its natural environment.

Activity:  Metamorphosis Magic Teacher Background: **Note** This lesson is not meant to be intimidating.  The discussions and questions will take place in a time frame that individual teachers will determine.  The journaling and recording of information will be done daily.  I will introduce the Unit by presenting my Power Point.  We will discuss each stage as we go through the presentation.  We will begin raising our butterflies.  The students will work as a class to care for the butterflies.  The students will keep data on changes that they observe. These observations will be completed daily. The students will make predictions on when the butterflies will hatch.   Explain to the students that animals have adaptations which enable them to survive in their environment.  Explain that animals go through a series of changes from egg to the adult stage, which is capable of producing the next generation.  This series of changes is called the life cycle.  Explain that many types of animals do not depend upon the adult parent to care for them during their immature stages.  Explain that plants and animals depend upon each other in a community.
     When the caterpillars reach the chrysalis stage, they will fasten themselves to the top of the butterfly house.  After several days, depending upon the temperature of your room, the chrysalises will begin to gently twitch.  They will become slightly translucent, and then the amazing transformation will become apparent as the butterflies start to emerge. 
     A reddish fluid called meconium will stain the floor of the butterfly house.  The butterfly releases this fluid when it pumps its wings.  The butterfly won’t fly until its wings dry out.
     Students will observe the long drinking tube called a proboscis unfurl as the butterflies sip the sugar water.
     Discuss the fact that butterflies don’t have live babies but lay eggs upon leaves.                                                
 Students: Using the butterfly house each day, the students will be responsible for observing the butterfly larva.  They will need to give a complete description of the caterpillar, including its size.  Students will use a paper ruler to measure the caterpillar in the cup, without removing and possibly harming it.  They can fold the ruler and place it alongside the larva. Once the butterfly emerges, it can feed on sugar water that has been placed in a shallow bowl until its release.  Students will chart their information on a table and in a butterfly journal. The teacher and students will discuss the following questions: Where would a butterfly find a sweet liquid like the sugar outside? (Nectar from flowers.)  Why do butterflies need such long straw like jaws? (To reach inside the flower petals for the nectar.)  What could get picked up by the butterfly as it sat upon a flower? (Pollen)  Does anyone think that the butterfly looks like the larva that it used to be?  What does the word “metamorphosis” mean? (a complete form change).  Do people go through metamorphosis?  How do you know?  What is the advantage of metamorphosis?  (It enables the species to use two different sources of food—plant leaves and nectar—and thus is an adaptation which increases the survival of the species.) Why don’t butterflies have live babies but lay eggs upon leaves?  (When the tiny caterpillars hatch, they don’t have to look for food.  That is the total extent of the care given by a mother butterfly to its young.)  Why are so many eggs laid?  (Most are eaten by ants and some spiders, or destroyed by smaller insects which lay their eggs inside the butterfly eggs.  When the insect’s larvae hatch, they eat the butterfly eggs.)

Assessment: This will be done over the duration of the unit and will include teacher observation, checking the journal entries for information accuracy and correct sentence structure (i.e. punctuation, spelling, capital letters, use of vocabulary), completion of a butterfly life cycle work sheet

Materials:  Butterfly House from http://www.earthsbirthday.org/;  Cooperative Learning: Science, Scholastic Professional Books (includes data worksheet and paper centimeter ruler); student journals from http://www.starfall.com ; digital camera to document growth.

 

 

Lesson Three:  Introduction to Insects

Objectives:  Students will develop an awareness of physical attributes and characteristics which define an insect and the roles that they play within our world.

Activity:  Tell the students that we will be studying insects.  Explain that we’ll be completing student insect worksheets that will be put into a booklet that they can keep.  Give each student a KWhL chart.  Explain that a KWhL chart is used to help identify things that they already know and what they would like to learn.  The K section stands for things that I KNOW about insects.  The Wh is for things that I WANT to know about insects and how I might learn this things.  The L is for things that I LEARNED about insects.  Have the children complete the K and W sections on their charts.  On an overhead transparency create a class KWhL chart.  Remember to leave the L section blank and fill it in at the end of the unit. 

Assessment:  Teacher will check students’ charts for completion and correctness.  Teacher will observe the students and evaluate them on participation in group discussion.

Materials:  overhead projector; KWhL charts for students (may make your own or obtain one from the following website: http://www.ckcolorado.org/units/2nd_grade/2_whatsbuggingyou.pdf

 

 

 

 

Lesson Four:  Insect Inspectors/Bug Trappers

Objective:  Students will remove insects from their natural environment in order to explore their structures and behaviors and to recognize what insects are common in our area.

Activity: Write the definition of an insect on the board.  Encourage the students to help with this (shared pen).  Tell the students that we’re going to pretend to be entomologists (scientists who study insects).  Make a bug catcher to observe insects.  Cut off the top 4 inches of a 2-liter plastic soda bottle.  Place half of an over-ripe banana in the bottom part of the bottle.  Insert the top part of the bottle backward into the bottom part.  Lay the bug catcher on its side on the soil for 6 to 8 hours.  Observe the bug catcher as often as possible during the 6 to 8 hours.  Use the website http://www.insectainspecta.com to help identify the insects that enter the bug catcher.  Observe and discuss the body parts of the insects.  At the end of the experiment, release insects where you found them.  Study insects in different locations by placing the bug catchers in different areas.  Have each student prepare a page that contains information about one of the insects that entered the bug catcher.  Include the common name of the insect, a written and visual (may use the digital camera) description, the location, and any miscellaneous information.

Assessment:  teacher observation (including group participation), ability to label body parts on a diagram

Materials: empty, clean 2-liter soda bottles; over-ripe bananas; diagram to label body parts of an insect (create your own or go to website noted in lesson three)

 

 

Lesson Five:  Helpful and Harmful Insects

Objective: Students will become aware of the roles that insects play within our world.

Activity:  Tell students that we’re going to learn about how insects affect people.  Ask if students think that insects are helpful or harmful.  On the board, generate a class list of ways that insects are harmful and ways that insects are helpful.  Watch a video on helpful and harmful insects.  After the video, add additional information to the list on the board.  Students will complete a worksheet on helpful/harmful insects.

Assessment: Teacher will check student’s answers for completion and correctness.  Using a rubric, teacher will observe the students and evaluate them on class discussion participation.

Materials:  video on helpful and harmful insects; worksheet on helpful/harmful insects (may make your own or use one from website noted in lesson three); rubric from http://www.teach-nology.com
