Ashley Fawley Fossils and Extinction- Guided Discovery Model Educ 317 – Spring 2013 ECE only Major Grade Level/Subject: 2nd grade/ Science Topic: Fossils and Extinction Day one: 45-50 minutes Day two: 90 minutes Day three: 30 minutes Length of Lesson Total: 2 hours and 45 minutes This lesson will look at different living things that are no longer in Overview of Lesson existence. The lesson will talk about why certain living things are not in existence anymore. The lesson will go over how we know certain living things were in existence at one time. The lesson will focus on what a fossil is, and how they are formed over time. Grade Band Theme: Observations of the Environment Life Science Strand: Strand Connections: Living and nonliving things may move. Changes in energy and movement can cause change to organisms and the environments in which they live. Interactions within habitats Topic: This topic focuses on how ecosystems work by observations of simple interactions between the biotic/living and abiotic/nonliving parts of an ecosystem. Just as living things impact the environment in which they live, the environment impacts living things. Some kinds of individuals that once lived on Earth have completely Content Statement: disappeared, although they were something like others that are alive today. Instructional Objective(s) Scientific Skills 1) Students will identify at least 3 living things that no longer exist. 2) Students will understand how fossils are formed. 3) Students will understand how we know about living things that no longer exist. 4) Students will create their own fossil 5) Students will be able to identify a fossil and explore it. 6) Students will be able to compare and contrast an extinct animal to an animal that is still living today. Observation – students will observe different fossils, and why they were formed. Classification- students will classify living things that are still existence with living things that are still on earth today. Inferring- students will interpret what fossils are and think about where they could have come from. Predicting- students will predict what they may find in the fossil activity. Students will also predict what living things could come extinct in the future. Communication-students will communicate what they find through their exploring, in the lesson Ashley Fawley Fossils and Extinction- Guided Discovery Model Educ 317 – Spring 2013 ECE only Major Curricular Integration Materials Prior Preparation Language –Students will complete a writing assignment on an animal that is no longer in existence. What may have life been like for them? Why are they no longer in existence? Students will read different books on extinct animals. Social Studies- looking in the past, what living things are no longer in existence? Why? Looking at environmental and social problems. Math-Looking at large numbers. Dinosaurs have been extinct for 65 million years. How big is one million? Supplies: Three large totes (plastic) Sand Shells Small plastic toys Feathers Rocks Leaves Sticks 6-8 plastic shovels Sifters Clay (Salt, flour, water) Acorns pinecones Construction paper Glue Scissors Crayons Markers Computer access (4-5 at least) Clay: Before the lesson I will make clay for the students to use in an activity later on in the lesson. Directions for clay are as follows. Items needed: 1 cup of salt 1 cup of flour ½ cup of water Ashley Fawley Fossils and Extinction- Guided Discovery Model Educ 317 – Spring 2013 ECE only Major Instructions: 1. In a large bowl, combine the salt and the flour 2. Make a well in the salt/flour mixture and add the water 3. Knead until smooth and shape into a ball 4. When not in use, wrap in plastic or store in an airtight container To get softer dough you can add more flour. Adding more salt will lend a more granulose affect. To add color to your dough, add food coloring or paint. Knead to get an even color. Paint your ornaments and sculptures after they dry. Before class I will collect different objects that students can use to make their own fossils later on in the lesson. I will collect leaves, acorns, pinecones, shells, rocks etc… Focus /Engage Anticipatory Set Objective (as stated for students) Procedure Guided discovery Start the lesson out with the following questions: What does the word extinct mean? What kinds of animals are extinct? Why are there living things that no longer exist? What is a fossil? At the beginning of the lesson I will start out by asking these questions. Students should start forming questions of their own, to explore later on. I will provide the definition of extinct for students, but other explanations will be saved for later. After asking questions to get students thinking I will start out with a short video. http://www.youtube.com/watch?v=kXzuDxp1-v4. The video will give students a few ideas of extinct animals, just to get them thinking about different living things that are no longer around. After the video I will ask students to start thinking about how we learn about living things that are no longer alive on earth. Today we are going to learn about things that once used to be existence on the earth, but are no longer alive today. We will look at how we know they once existed. We will explore like archeologists do to find different things that may be embedded in the earth. We will also explore different fossils, and then you will make your own fossils. Exploring Day One Ashley Fawley Fossils and Extinction- Guided Discovery Model Educ 317 – Spring 2013 ECE only Major Questioning/reevaluating Teacher Talk Group Practice Students will be split up into 4 different groups. Each group will have a tote full of sand, and 4-5 plastic shovels, sifters etc... In each tote there will be different things buried in the sand. Students will have 15-20 minutes to explore in the sand and find the different hidden things throughout the sand. Students will be asked to think about the job of an archeologist. What does an archeologist do? What are you going to find? How will what you find relate to things we may find from living things that no longer exist? How could you display what you find so others can learn from you? Each group will be encouraged to explore on their own. Students will be asked to think of questions they may want to After all groups have dug through the sand for around 20 minutes I will ask all students to come back together. I will ask every group to explain some of the things that may have found. What did you find? What do you think an archeologist does? How do you think we find out about animals that no longer exist based on the activity we just did? How can others learn about living things that are extinct? Every group will have an opportunity to share what they have learned and would like to learn more about. Students will be instructed to start thinking about extinct animals and fossils for the next day’s lesson. Day Two The next days after questions have been discussed. I will have students get back into their groups. Each group will be provided with markers, crayons, glue, scissors, construction paper, clay, and access to a computer. There will be a collection of stuff that students can use to make their fossils out of clay. Students will be shown how to press out a piece of clay and then put a leave/rock etc… into the clay to make an impression. After the clay dries the students can take their fossils home. Each group will be asked to make a 5 minute presentation for the class. Ashley Fawley Fossils and Extinction- Guided Discovery Model Educ 317 – Spring 2013 ECE only Major Checking Understanding/ Reinforcement The guidelines for the presentation will be: What did you find out that an archeologist does? Pick an animal that is not extinct and tell the class a little bit about your animal. Provide a visual. Share with the class what you found on your archeological dig. Make a fossil to share with the class Students will have freedom to decide how they want to do their presentation. I will provide a few examples of a report/museum type display/pictures etc… to get students thinking about how to do it there presentation, but it will be up to them to decide how they want to present their information to the class. Students will have an hour of class time to work on their presentations. Each group will have 5 minutes to show their project to the class, and explain what they learned. Every group should explain what extinct animal they chose; share a few facts/pictures about that animal as well. Every group will show what they found during their dig, and also what they came up with as a group to the questions they were presented with as well as the questions they came up with themselves. Each group will also share the fossils they made and how they made them. Questions that should be addressed through presentations: What is an archeologist? What is a fossil? Where are fossils found? What animals are extinct? Why do animals become extinct? What do fossils show us? Can you make fossils? Day Three Finishing up the lesson I will reinforce some concepts that I may feel like students have not completely understood about extinct living things, and how we learn about them. I will finish the lesson up with a short YouTube video. http://www.youtube.com/watch?v=XG5gcnIWuw0 Throughout the video I will stop and explain to students Ashley Fawley Fossils and Extinction- Guided Discovery Model Educ 317 – Spring 2013 ECE only Major different concepts about fossils and extinct animals. I will ask questions that will help them tie the video into the activities they have done the previous few days. Questions throughout YouTube video: Based on what you learned the past two days: What does this fossil look like? What kind of animal could it have come from? Is that an extinct animal? Why are some animals extinct now? Who would find these fossils? Homework Practice At the end of the lesson I will pass out a worksheet to every student to do at home. Each student will be asked to pick an extinct animal. They can use the same animal they used on their group project if they would like. Students will fill out the Venn diagram worksheet comparing the extinct animal they choose to an animal that is still living today. Students will write 3 facts about the extinct animal in one side, 3 facts about the animal that is still alive in the other side, and 3 things that make them similar in the middle. Students then will write 2-23 sentences explaining what kind of fossil they think that extinct animal would make, and how. Assessment Students will assessed a variety of different ways throughout the different days. Day one: Students will be assessed through the group work. During the group exploring I will walk around and observe. Students should be making their own questions and connections of the different ideas presented to them. Through observation I will be able to assess what the students understand. Day Two: Students will be assessed based on their group presentations. I will be looking to see: Did students follow the guidelines given to them? Did the students pick a extinct animal? Was the information presented in a good way to the other members of the class? Do the students understand the idea of a fossil and how they are Ashley Fawley Fossils and Extinction- Guided Discovery Model Educ 317 – Spring 2013 ECE only Major formed? Were students able to construct their own project with the few guidelines given to them? Each group will get a group participation grade for the presentations if all guidelines were followed correctly. Day Three: I will assess students through the worksheets they turn into me for homework as well. At this point students will have to work independently so I will be able to fully assess where each student is individually. Home Extension Additional Reinforcement Additional Opportunities Accommodations Encourage students to explore other extinct species outside of class. Students can make fossils at home, and I will provide a copy of the clay recipe if a student would like it. There are many online resources that will be made available to students during an extra free time. http://www.sheppardsoftware.com/content/animals/kidscorner/endange red_animals/endangered_game.htm http://kids.sandiegozoo.org/games www.pbs.org There will be plenty of literature books provided for students to look at and use: Fossils by Chris and Helen Pellant. Fossils by: Rebecca Faulkner. V for vanishing by Patricia Mullins. Ice age animals by Louise Spilsbury. I will provide resources for students of different museums/ exhibits they may be interested in when it comes to learning about extinct species. The Ohio Historical Society has a neat exhibit on extinct species (mammoths, dinosaurs, etc…) Students will be carefully grouped together in order to get students that will work best together. Students that need more direction then given will have an opportunity to talk with me, and work with me one on one. Computer activities/ books will be available to students who may finish early.
