For the first round of searching, select one of the un-punched pieces of paper, this becomes your 'habitat'. Mix the dots and then dump them over the habitat sheet.

Now, you are the predator. With your friend timing you, pick up as many 'prey' dots as you can in 30 seconds. You may pick up only one dot at a time, and you may not pick up the habitat.

After 30 seconds, count the number of colored dots collected and record the number on the table. Return all of the dots to the container and repeat the process using the other three colored habitats.

Next, go outdoors and try this activity using colored toothpicks or beans. Count out an equal number of each. Select an area about 10 feet by 10 feet. Choose a lawn, playground, asphalt, or concrete surface or any without tall bushes or plants.

Scatter the colored toothpicks or beans over the measured area. Have your friend time you for 30 second as you collect as many toothpicks or beans of different colors as you can.
