Key Concepts to Remember
- Homeostasis: The body's ability to maintain stable internal conditions.
- Matter: Anything that has mass and occupies space; exists in three states (solid, liquid, gas).
- Energy: The capacity to do work, existing in various forms (kinetic, potential, thermal).
- Force: An interaction that changes the motion of an object; described by Newton's laws.
Study Tips
- Create flashcards for key terms and concepts.
- Engage in hands-on experiments to reinforce theoretical knowledge.
- Utilize group study sessions for discussion and clarification of complex topics.
- Practice past exam questions and review study guides.
