Learning Objectives:

After completing these activities, students will be able to:

• Identify the five main senses and the specialized receptors animals use to gather environmental information.
• Explain the three-step "sense-process-respond" model and the role of the brain as a control center.
• Compare unique physical structures, such as compound eyes or asymmetrical ears, and describe how they aid in survival.
• Describe how nerve cells function like wires to carry messages between receptors and the brain.
• Differentiate between innate instincts and behaviors learned through past experience and memory.
• Analyze real-world examples of animal adaptations, such as bat echolocation and octopus camouflage.
