Dear Parent or Guardian,
Our science class will soon begin exploring the chapters about the human body.
Florida Sunshine State Standards
The following standards are addressed in this chapter:
F.1.3.1 AA understands that living things are composed of major systems that function in reproduction, growth, maintenance, and regulation.
F.1.3.3 CS knows that in multicellular organisms cells grow and divide to make more cells in order to form and repair various organs and tissues.
F.1.3.4 CS knows that the levels of structural organization for function in living things include cells, tissues, organs, systems, and organisms.
F.1.3.5 CS explains how the life functions of organisms are related to what occurs within the cell.
In chapter 5, students will learn about the organ systems, the skeletal system, the muscular system, and the integumentary system, etc. By the end of the chapter, students should demonstrate a clear understanding of the chapter’s main ideas and be able to discuss the following topics:
1. the major tissues found in the body (Section 1)
2. a comparison between an organ and an organ system (Section 1)
3. the major organs of the skeletal system (Section 2)
4. the functions and internal structures of bones (Section 2)
5. a comparison of three types of joints (Section 2)
6. the major parts of the muscular system (Section 3)
7. the way that skeletal muscles move bones (Section 3)
8. a comparison of aerobic exercise and resistance exercise (Section 3)
9. the major functions of the integumentary system (Section 4)
10. the major parts of the skin and their functions (Section 4)
Questions to Ask Along the Way
You can help your child learn about these topics by asking interesting questions as he or she progresses through the chapter. For example, you may wish to ask your son or daughter the following questions:
• What soft, flexible tissue can develop into bone?
• How can you strengthen your heart and increase the endurance of skeletal muscles?
• What determines the color of hair?
• What are common ways that the skin is damaged?
In chapter 6, students will learn about the circulatory, lymphatic, and respiratory systems of the human body. By the end of the chapter, students should demonstrate a clear understanding of the chapter’s main ideas and be able to discuss the following topics:
1. the functions of the cardiovascular system (Section 1)
2. the three different types of blood vessels (Section 1)
3. the path that blood travels as it circulates through the body (Section 1)
4. the different blood types (Section 2)
5. the functions of the lymphatic system (Section 3)
6. the relationship between lymph and blood (Section 3)
7. the organs of the lymphatic system (Section 3)
8. the flow of air through the respiratory system (Section 4)
9. the relationship between the respiratory system and the circulatory system (Section 4)
10. some respiratory disorders (Section 4)
Questions to Ask Along the Way
You can help your child learn about these topics by asking interesting questions as he or she progresses through the chapter. For example, you may wish to ask your son or daughter the following questions:
• Why is blood red?
• Why do people have different blood types?
• What is lymph?
• Why does the body need oxygen?
In chapter 7, students will learn the structures and functions of the digestive and urinary systems. By the end of the chapter, students should demonstrate a clear understanding of the chapter’s main ideas and be able to discuss the following topics:
1. the parts and functions of the digestive system (Section 1)
2. mechanical digestion and chemical digestion (Section 1)
3. the parts and functions of the urinary system (Section 2)
4. the way that the kidneys filter blood (Section 2)
5. some disorders of the urinary systems (Section 2)
Questions to Ask Along the Way
You can help your child learn about these topics by asking interesting questions as he or she progresses through the chapter. For example, you may wish to ask your son or daughter the following questions:
• What are the two different types of digestion, and how do they differ?
• How do nutrients get into the bloodstream?
• Why is it healthy to chew your food thoroughly?
• Why is it healthier to drink water than it is to drink soda?
In chapter 8, students will learn about the brain, the nervous system, and the endocrine system. By the end of the chapter, students should demonstrate a clear understanding of the chapter’s main ideas and be able to discuss the following topics:
1. the way that neurons in the nervous system work together (Section 1)
2. differences and similarities between the central nervous system and the peripheral nervous system (Section 1)
3. the major functions of the four parts of the brain and the spinal cord (Section 1)
4. the sensations that are detected by receptors in the skin (Section 2)
5. the relationship between light and vision (Section 2)
6. the differences and similarities between the functions of photoreceptors, taste buds, and olfactory cells (Section 2)
7. the function of the endocrine system (Section 3)
8. the glands of the endocrine system and some of their functions (Section 3)
9. the way that feedback controls stop and start hormone release (Section 3)
Questions to Ask Along the Way
You can help your child learn about these topics by asking interesting questions as they progress through the chapter. For example, you may wish to ask your child the following questions:
• What does the nervous system allow you to do?
• Which of your senses is most important to you?
• Where do you recognize bitter tastes?
• Which hormone is associated with fight-or-flight situations?
