|Objective||The student wil be able to sort and classify the four Arthropod classes.|
Science TEKS Grade 3 (2) Scientific Inquiry: Field and Laboratory
b. collect information: observe and measure
c. analyze and interpret information to construct explanations from direct and indirect evidence.
Science TEKS Grade 3 Systems (10) Likeness between Offspring and Parents Inherited from Parents
b. identify inherited traits in animals
Math TEKS Grade 3 (14) Displaying and Interpreting Data
collect, organize, record and display data in picture and bar graphs; interpret information from graphs.
Poster Board (one per group)
Examples of each Arthropod class (One example from each class/group)
Pictures of Arthropods cut into puzzle pieces
Students are given puzzle pieces of one Arthropod example. Place the students in groups of five and give each group a Arthropod puzzle. The challenge for the group is to put their puzzle together, glue it on a piece of construction paper and label the ir puzzle. This is a silent activity and each group is to display their picture on the board when completed.
Students remain in their groups and are given examples of each class of Arthropod. Through observation and group discussion students will list and illustrate on the poster board Differences and Similarities of each of the Arthropod classes.
Each group wil share their findings with the class. The class will look for common findings among the groups and the teacher will list them on the overhead. The teacher will present the formal Arthropod classes and the students will connect this to th eir findings.
The student will draw two examples of each of the Arthropod classes on index cards. In pairs, students will play the game "Go Fish", using their index cards.
