§112.3. Science, Grade 1.

TEKS ADDRESSED: (2) Scientific processes. The student develops abilities necessary to do scientific inquiry in the field and the classroom. The student is expected to:

(A) ask questions about organisms, objects, and events;

(7) Science concepts. The student knows that many types of change occur. The student is expected to:

(D) observe and record stages in the life cycle of organisms in their natural environment.

(9) Science concepts. The student knows that living organisms have basic needs. The student is expected to:

(A) identify basic needs of living organisms;

(B) give examples of how living organisms depend on each other; and

CONCEPT STATEMENT:

Many different types of animals are born from eggs. Students should recognize that different hatching animals lay eggs in different types of environments. They should also understand that some animals eat other animals while some eat plants. They should begin to understand the basic needs of living organisms.

PERFORMANCE OBJECTIVES:

SWBAT identify multiple animals that hatch from eggs
SWBAT identify which animals lay eggs on land and which animals lay eggs underwater

RESOURCES: For the group:

1 live box turtle
1 live toy turtle
2 small toy turtles
2 ping-pong or Styrofoam balls
1 toy dog
1 tub filled with sand
1 paper grocery bag
1 turtle laying eggs poster (in guide)
Colored pictures of turtles and turtle eggs
2 strawberries
1 tomato cut into quarters

SAFETY CONSIDERATIONS: Student will be working with a box turtle. The children must be warned while meeting the turtle not to touch its head in case it bites or they poke it in the eye. Turtles can also carry salmonella, so the turtle must first be taken to the vet to make sure it is disease free. The children must always wash their hands after handling the turtle.

SUPLEMENTARY MATERIALS, HANDOUTS: None

What the Teacher Will Do	Probing Questions	Student Responses Potential Misconceptions
Introduce the box turtle. Sit on the floor in a circle with the students. Put the turtle on the ground with its head away from me. Tell the students they will each have an opportunity to touch the turtle’s shell and legs. Count the turtle’s eyes, legs and toes with the children. Put the strawberry and tomato in front of the turtle to see if it will eat them. Then put the turtle back safely in the terrarium.	1. Why is it best not to touch the turtle’s head? 2. Why do you think the turtle pulls his head and legs in the shell? 3. Why do you think turtles have shells?	1.[He’ll bite us] 2. [He’s scared] 3.[For protection] it’s their home
Show the turtle laying eggs picture	1. What do you see in the picture? 2. Where is the turtle laying her eggs?	1.[A turtle and her eggs] 2.[In the ground] in the water

What the Teacher Will Do	Probing Questions	Student Responses Potential Misconceptions
Present a drama about a mother turtle laying her eggs and baby turtles crawling out of their nest. Use the prepared toys and tub of sand to act out turtle behavior during the story. Students will be in a circle, around the tub where everyone can see. A mother turtle is eating a strawberry on a hot summer day. A dog sniffs the ground as it walks toward the turtle. (If possible, place the turtles head and legs under shell) The turtle is so still and looks so much like a rock that the dog walks away (walk the dog to the bag and put it in) The mother turtle is about to lay eggs. She needs to find a safe place to hide them. She uses her back legs to dig a hole in the sand and drops her eggs into the hole. (Place the two eggs in the hole). She uses her back legs to cover the eggs with sand so they are hidden. She then leaves her nest (walk turtle to the bag and put her away) A long time goes by. Then something exciting happens. The baby turtles hatch out of their eggs, dig through the sand and suddenly appear. (Crawl the turtles out from the sand.) The baby turtles look for food. · The little turtles nibble on the strawberry and tomato. They are big enough to take care of themselves.	1. What do you think the turtle will do if the dog comes too close to it? 2. Why do you think the dog leaves the turtle alone? 3. What do you think the baby turtles will eat?	1. [Hide in its shell] run away 2. [he doesn’t know what it is, it looks like a rock] he’s scared of it, dogs don’t eat turtles 3. [Strawberries and tomatoes, grass] sand, the dog, each other
The tray and props should be left in the play area to be explored further during free time.

What the Teacher Will Do	Probing Questions	Student Responses Potential Misconceptions
Have students explain what they saw in the drama. Explain to students the terms incubation and egg tooth.	1. Do all animals hatch from eggs? 2. What do we call animals that are born alive and not hatched from eggs? 3. What are some more groups of animals that are hatched from eggs?	1.[no] yes 2. [mammals] birds, bugs, reptiles, amphibians 3. [Birds, bugs, reptiles, amphibians.

What the Teacher Will Do	Probing Questions	Student Responses Potential Misconceptions
The students will look through books to find other animals that lay eggs, in water or on land. They will draw a picture of the animal, label it, and label where the animal lays its eggs. Then the class will divide into groups according to where their animal lays its eggs and discuss how they came to that conclusion. The teacher will circulate through the groups listening to explanations and asking questions.	1. Why do you think that animal lays its eggs on land (water)? 2. What do you think that animal will eat? 3. The turtle had to hide her eggs; do you think your animal will hid her eggs?	Responses will be dependent on the student’s chosen animal.

Evaluation		Time: ________
What the Teacher Will Do	Probing Questions	Student Responses Potential Misconceptions
Have students put their pictures in their portfolios. As a ticket out the door, each student must name an animal that lays eggs, and where.	1. Name one animal that lays eggs, and where do they lay them?	1. [bird] in the water [fish in the water] [turtle] in the water
