The objective of these activities is to provide the students with opportunities to use measurement, geometry and statistical measures in the natural environment.

Directions:

Students should be divided into groups of 4-5 members.  Each group has about 10 minutes to complete the activity sheet at each center.  Each person in the group will share the responsibilities of getting the necessary information and will record the data on their own sheet.  There are (3) activities to completed at this station.  Do not move to the next activity until time is called.

Use the circular concrete slab to complete the following information:

1.    Find the diameter to the nearest whole foot                _______________ feet

2.    What is the radius?                                                        _______________ feet

3.    Compute the circumference                                           _______________ feet

4.    Compute the area                                                           _______________ square feet
 

Formulas:                                                                            Circle vocabulary:

r = 1/2d                                                                          diameter - distance across the circle
C=      d                                                                          radius - distance from the center of the
A =      r      (use    = 3.14)                                                             circle to edge of circle
                                                                                      circumference - distance around the circle

Directions: Part A

Each person in the group will walk, using normal steps, from the pecan tree to the chain link fence.         Count and record the number of steps it takes to cover the distance for each person.

                    Name                                                                                        # of steps

Directions: Part B

                    Find the following statistical measures for your group's data?

                    Mean = __________________ steps

                    Median = _________________ steps

                    Mode = __________________ steps

                    Range = __________________ steps
 
 

Part A:
Take a few minutes to hunt for at least 5 items ( 1 item per group member)  Try to find lines of symmetry in the items you selected.  List and briefly describe the items below

               Item Name                                             Lines of Symmetry                         Discovered by which team member
 

1. ______________________               ___________________                ________________________

2. ______________________               ___________________                ________________________

3. ______________________               ___________________                ________________________

4. ______________________               ___________________                ________________________

5. ______________________               ___________________                ________________________
 

Take each of these items and place them underneath your paper and do a crayon rubbing using the bottom half of this page.
