Turtle Tales (Grades 2-3)

MASTER TEACHER

Rhonda Hollingsworth

OVERVIEW

Students will hold onto their hearts as they travel with mother sea turtles on a marvelous journey to their nesting sites on a Costa Rican beach. They'll learn to appreciate the innate ability possessed by animals for survival.

SC MATH/SCIENCE STANDARDS MET

Science Achievement Standards Strands

Science Area I Living things

Strand 1: Characteristics of Living Things

Investigate the relationship between living things and their habitats

Strand 2. Organisms Interact with their Environment

Investigate and analyze ways in which living things interact with each other and with the environment

Interpret a Food Chain

Investigate characteristics and behaviors of plants and animals that help them to survive in specific environments

Strand 3. Organisms Change

Observe similarities and differences in the growth and development of living things throughout their life cycles

Area IV Applications

Strand 1. The Earth and Sun as Natural Resources

Communicate the importance of protecting the earth's resources.

Math Achievement Standards

Number and Numeration systems-Primary Grades

Relate the use and understanding of numeration systems to their world by using appropriate technology.

Numerical and Algebraic Concepts and Operations-Primary Grades

Use models to allow students to construct their own algorithms for addition, subtraction, multiplication and division of whole numbers by using concrete or pictorial models to demonstrate an understanding of multiplication.

Geometry and Spatial Sense-Primary Grades Investigate and predict the results of combining and partitioning geometric shapes by combining and/or partitioning common two-dimensional geometric shapes to form new shapes.

PRE-VIEWING

Draw a sea turtle web on a piece of chart paper. (See the Sea Turtle Web at the end of this lesson.) Ask the students what they'd like to discover about sea turtles. Write six responses on the turtle. Demonstrate by writing this question on one of the turtle's legs. 'How do turtles know when to start their journey to land?" Try to cluster questions.

FOCUS FOR VIEWING

To give students a specific responsibility while viewing, do the following:

Give each student a blank sheet. Instruct them to predict predators sea turtles might encounter either in or out of the water as they journey to their nesting site. Instruct them to draw the predators in an ocean or beach setting.

When the students have had a sufficient amount of time to finish their drawings, inform them they are going to be viewing mother sea turtles and later their hatchlings as they encounter various predators. Instruct them to keep their drawings in front of them during the video and to circle any predators they drew if or when that predator appears on the screen.

VEWING ACTIVITIES

Start Kratts' Creatures: Arribada 1: The Sea Turtle Invasion video where the shark is chasing the mother sea turtle. let the video run to the end.

Use tally marks to record on chart paper the correct predictions students had of predators. First, using a sheet of chart paper, list the predators that were seen. Then, call out each predator and have students raise their hands if it was a predator they had drawn on their paper. Display the chart in a prominent place. Example-.
Sharks - III
Raccoons - I
Birds - I
Alligators-III

Start the Math Cycle video after the scene of the earth turning. It win be very near the beginning of the video. The narrator says, 'We measure whole days on a calendar. '

Stop it when an outline of a clock is on the screen and after the narrator says, 'One minute equals sixty seconds." Ask, "How do people tell time?' Call on several students.

Ask, 'How did the sea turtles tell time?" Call on several students.

Write "instinct" and 'learned" on the board. Define each in your own words to the class. Webster's Universal Dictionary and Thesaurus gives the following definitions:

instinct- the inborn tendency to behave m a way characteristic of a species

learned- acquired by study

Call on students to give examples of instinctive behavior in both animals and people.

Call on students to give examples of learned behavior in both animals and people.

Make a T chart showing your comparisons.

POST VIEWING ACTIVITIES

Distribute copies of Activity Sheet 1: Turtles and Tune concerning mother turtles and time. Instruct the students to draw lines from the mother turtle and from the child to the ways each tells time.

Distribute Activity Sheet 2 and follow the instructions to make a fold-out of a sea turtle's life cycle.

Use Activity Sheet 3 to play Swimming to Costa Rica. You will need to divide the students into teams of two or three. The instructions for playing are given on top of the game sheet. Each player will need two pennies to begin.

EXTENSIONS

Using information given in the Kratts' Creatures video, guide students to discover how many eggs the sea turtles lay during the Anibada.

Distribute blank pieces of drawing paper to students. Tell them that they are going to make a pictorial model of the beach.

Instruct students to draw a picture of just the Costa Rican beach. Instruct them to add a very large sea turtle to their beach scene. Demonstrate how an oval can be the turtle's body and rectangles can be its legs.

Instruct students to write 40,000 on the sea turtle's body. Instruct them to draw a circular nest and write 100 on it. (There are 40,000 sea turtles. Each one lays 100 eggs.) Instruct them to complete the picture as they choose.

After a sufficient amount of time, ask, "How could we find out how many sea turtle eggs there were in all on the beach in Costa Rica?" Ask, students what types of strategies they could use.

Distribute calculators. Give instructions on how to multiply using a calculator.

First, tell them to punch in 40,000.
Next, tell them to punch the X sign.
Then, tell them to punch in 100.
Finally, tell them to punch the = sign.

Call on volunteers to write their answers on the board.

Have students write story problems involving the predators. After a sufficient amount of time, call m several of the students to read their problems aloud while the rest of the class listens. Have students solve them.

Ex: One sea turtle lays 100 eggs. A sea gull eats 3. An alligator eats 27. How many are left?

Make Sand Cup Snacks

1 package (12 ounces) vanilla wafer cookies

2 cups cold milk

1 package (4-,serving size) JELL-0 vanilla flavor instant pudding & pie filling

1 tub (8 ounces) COOL WHIP Whipped Topping, thawed

8 - 10 (7-ounce) paper or plastic cups

Suggested garnishes: gummy fish, chopped peanuts, granola

Serves 10

Crush cookies in zipper-style plastic bag with rolling pin or in food processor. Pour milk into large bowl. Add pudding mix. Beat with wire whisk 2 minutes. Stir in whipped topping and half of the crushed cookies.

Place about 1 tablespoon of the crushed cookies in each cub. Fill cups about 3/4 full with pud- ding mixture. Top with remaining crushed cookies.

Refrigerate until ready to serve. Garnish as desired.
