Review the concept of habitat - that a bear would need shelter, food, water and space in a suitable arrangement in order to survive. Do not tell the students what the letters on the squares of paper represent. Tell them only that they represent one element or component of bear habitat. Each bear must pick up as many of the components of habitat as posdble. Some competitive activity is acceptable as long as it is under control.
Bears are territorial.
Remember that if bears fight, which they seldom do, they can become injured and unable to successfully meet their needs for survival. When the students have picked up all of the squares of paper in the area, have them return to the classroom or be seated in any comfortable area. Ask the students to separate their squares of paper into piles according to the letter on each. Using a chalkboard or large pad for a visual reference, ask the students to guesss what the letters on the green cards represent - giving them the clue that each is an element of cover or shelter for a black bear. Record how many bears got at least one of each kind of shelter.
