Diversity Lab Name: _____________________________
H. Life Science Period: ________ Date: _______________
As you well know, we are all the same species - Homo sapiens - but we differ a lot from each other - especially between boys and girls! This laboratory experiment will show you just how much!
Materials:
Tape Measure
Meter Stick
Lab Handout
Skills:
Prediction:
Observe, compare, graphing data
Which gender will have the biggest heads? ____
Data Sheet
Graph Paper
Pen or Pencil
Which will be the tallest? ____
Which will have the bigger feet? ____
The bigger hands? ____
Procedure:
1.
Using the metric system, take a measurement of your head circumference - go above the eyebrows, over the ears and around the back. You will need a partner to help you. Record your data.
2.
Do the same for: a.
Footlength - back of heel to the tip of your longest toe – yes, take your shoe off! b.
Height - mark the wall with a piece of tape, then measure c.
Armspan - arms out to side, from fingertip to fingertip d.
Handspan - spread your fingers out as much as possible on a piece of paper - make a mark at the tip of your pinky and at the tip of your thumb - measure this length.
3.
Record your data.
4.
Get the same data from the rest of your group.
5.
Gather the data from all the other groups.
Analyze:
1.
Look at your data - think about how you would like to represent your data graphically - would a pie chart be best? Or a line graph? A bar graph?
2.
In your lab group, decide who is going to do which graph and how it is going to be done. Each lab member should be responsible for producing at least one graph! Be sure to include a title and a key describing each graph. A graph should be done for age, gender, head circumference, foot length, height, arm span and hand span.

Conclusion:
1.
Are there more males or females in the class?
2.
What is the most common age?
3.
What is the average age rounded to the nearest 0.1 year?
4.
Did you see any trend/pattern develop in your data?
5.
Did the data in a graph help you understand the trend/pattern? Why? Why not?
6.
Does there appear to be any major differences between the genders?

Using the metric system, take a measurement of your head circumference - go above the eyebrows, over the ears and around the back. You will need a partner to help you. Round to the nearest centimeter. Record your data.

Footlength - back of heel to the tip of your longest toe – yes, take your shoe off! f.
Height - mark the wall with a piece of tape, then measure g.
Armspan - arms out to side, from fingertip to fingertip h.
Handspan - spread your fingers out as much as possible on a piece of paper - make a mark at the tip of your pinky and at the tip of your thumb - measure this length.
8.
Record all the data from your group.
9.
Each lab group in class is going to do a graph for one of the following: A graph should be done for age, gender, head circumference, foot length, height, arm span and hand span.
10.
Your group will do a class graph for ____________________________________.
11.
Using the data group that is assigned to your lab group, go around to the other lab groups and copy their data onto your data sheet!
Analyze:
3.
Look at your data sheet - think about how you would like to represent your data graphically - would a pie chart be best? Or a line graph? A bar graph?

4.
Using one of the classroom computers, log in and pull up either Excel or Sheets.
Type in your group’s whole class data and create a graph. Be sure to include a title and a key describing the graph.
Conclusion:
1.
Are there more males or females in the class?
2.
What is the most common age?
3.
Did you see any trend/pattern develop in your data?
4.
