Choose an open location for the activity to take place, with the center area clear of any items that students may trip over.
Set out four 1-gallon buckets and add 5 pounds of rice to each one.
Next, add ¼ - ½ cup of dried black beans to the first bucket and mix the beans into the rice.
Then, add the same amount of dried pinto beans to the second bucket and mix them in.
Then add the same amount again of dried lentils to the third bucket and mix them in.
Finally, mix ½ to 1 cup of dried garbanzo beans into the fourth bucket.
Now, place the buckets next to each other in a row on one side of the room.
On the other side of the room, place one bowl and 10 cups of a single color next to each other per solitary student, alternating the cup color between each student, so that each student with blue cups will have neighbors with red cups, and vice versa.
For the eusocial group, place a bowl, 15 blue cups, and 15 red cups next to each other.
When all of the materials are in place, intersperse permanent markers among the materials for the students to use to label their offspring cups.
