Use your research to answer these more detailed questions.

1. Fill in the Blanks

• A black bear's coat isn't always black; it can also be shades of brown, cinnamon, or even ___.
• Despite their large size, black bears are surprisingly agile and can run up to __ mph (__ kph) and are excellent ___.
• A mother bear, called a sow, usually gives birth to a litter of __ to __ cubs in her winter den.

2. Bear vs. Bear Comparison

Black bears and grizzly bears are often confused. Fill out the table below to compare them. An example has been done for you.

Section 3: Real-World Connection - Coexisting with Bears

Black bears often live near human communities. Understanding their behavior is key to coexisting peacefully.

1. Why is it dangerous for both humans and bears when people feed wild bears?

2. Black bears are crucial to forest health. Describe one way they act as "ecosystem engineers." (Hint: Think about what happens after they eat berries.)

3. You are designing a sign for a campground. What are two essential safety tips you would include to help campers avoid negative encounters with black bears?

   • Tip 1:
   • Tip 2:

Section 4: Vocabulary Builder

Define the following terms in the context of a black bear's life.

• Forage:

• Hibernation:

• Den:

Section 5: Challenge & Reflection (Optional)

Human development is expanding into areas where black bears live, a process called habitat fragmentation. How might building a new highway through a large forest impact the local black bear population? What is one possible solution to reduce this impact?

Answer Key

Section 1: Quick Facts

• Kingdom: Animalia
• Class: Mammalia
• Average Lifespan in the Wild: 15-25 years
• Primary Diet Type: Omnivore
• Typical Habitats: Forests, mountains, swamps

Section 2: Deep Dive Investigation

1. Fill in the Blanks:

   • ...shades of brown, cinnamon, or even white/blonde (Kermode bear).
   • ...run up to 35 mph (56 kph) and are excellent climbers/swimmers.
   • ...litter of one to three cubs...

2. Bear vs. Bear Comparison (Sample Answers):	Feature	American Black Bear	Grizzly Bear
   Shoulder Hump	No prominent hump	Large, muscular hump
   Face Profile	Straight "Roman" profile from forehead to nose	Dish-shaped (concave) profile
   Claw Length & Shape	Short (1-2 inches), curved for climbing	Long (2-4 inches), less curved for digging
   Ear Shape	Taller, more pointed ears	Shorter, more rounded ears
   Typical Weight	150-300 lbs (male)	400-800 lbs (male)

Section 3: Real-World Connection

1. Why feed bears: It causes bears to lose their natural fear of humans (habituation) and associate people with food, leading to dangerous encounters. Food-conditioned bears are often euthanized.
2. Ecosystem engineers: They spread seeds from the fruits and berries they eat through their droppings, which helps plants and forests regenerate.
3. Campground tips (any two): Store all food and scented items in bear-proof containers or vehicles; Never leave food unattended; Keep a clean campsite; Do not cook in or near your tent.

Section 4: Vocabulary Builder

• Forage: To search widely for food or provisions.
• Hibernation: A state of inactivity and metabolic depression in winter. (Note: Bears enter a less extreme state called torpor, but hibernation is the commonly accepted term).
• Den: A wild animal's lair or home, used for shelter and raising young, especially during winter.

Section 5: Challenge & Reflection (Sample Answer)

• Impact: A highway can split their habitat, making it hard for them to find mates, search for food, and establish territory. It also increases the risk of bears being hit by vehicles.
• Solution: Building wildlife corridors, such as bridges or underpasses, can allow bears and other animals to cross the highway safely.
