BIOLOGY LESSON NOTE ON HUMAN KIDNEY

Image
Lesson Note on the Human Kidney Topic: The Human Kidney Duration: 40 minutes Specific Objectives: By the end of the lesson, students should be able to: Define the kidney and state its location in the human body. Identify and describe the structure and functions of the kidney. Explain the processes involved in urine formation (filtration, reabsorption, and secretion). Describe how the kidney contributes to homeostasis. Identify common kidney-related diseases and how to prevent them. Evaluate the importance of maintaining kidney health. Lesson Content: 1. Introduction to the Human Kidney The kidneys are vital organs in the human body responsible for filtering waste from the blood and regulating water and electrolyte balance. They are part of the excretory system and play a crucial role in homeostasis. Location: The kidneys are located in the abdominal cavity, on either side of the spine, just below the rib cage. Each kidney is bean-shaped and about the size of a fi...

PHYSICS LESSON NOTE FOR SS1 SS2 AND SS3

Week: one

INTRODUCTION TO PHYSISCS

Physics is a branch of science that deals with the study of matter in relation to energy. The branches of

Physics are: Mechanics, Light, Electricity, Waves, Magnetism, Atomic Physics, Electromagnetism,

Dynamics, Heat, Sound etc.

CONCEPT OF MATTER

Matter is anything that has mass or weight and occupies space. The idea that matter is made up of minute

particles called atom dated back to the ancient Greek. Atom is the smallest indivisible Particle of an

element which can take part in a chemical change. It consists of proton, neutron and electron. Proton is

positively charged, neutron is neutral and electron is negatively charged

Matter can exist in three states- Solids, Liquids and Gases

SOLIDS: The molecules of solids are closely packed together. They have definite shape and volume

LIQUIDS: Its molecule are freer than that of solid, they have definite volume but no definite shape

GASES: The cohesive force binding the gases molecules together is negligible. They have no definite

shape and Volume

QUANTITIES AND UNITS

There are two types:

1. Fundamental Quantities

2. Derived Quantities

1. Fundamental quantities and units: These are basic physical quantities or units that are

independent of others and cannot be defined in terms of other quantities or units. Examples of

Fundamental quantities are: Mass, Length, Time, Temperature, Electric Current, Luminous

intensity, Amount of Substance. While Fundamental Unit is given as: Kilogram (Kg), Meter (m),

Seconds (S), Kelvin (k), Ampere (A), Candela (CD), Mole (Mol).
