SCIENCE

Here’s a more highlighted version of the key points to focus on for your studies. The important parts are bolded and colored to make them easier to remember! Let’s highlight the critical concepts to help you achieve those top marks!

???? Food and Digestion ????

1. ???? Nutrients in Food

   Carbohydrates (Energy): Found in bread, rice, and pasta. ????‍♀️ Gives energy to the body.
   ???? Proteins (Growth): Found in meat, eggs, and beans. ???? Builds and repairs muscles.
   ???? Fats (Energy): Found in butter, oils, and nuts. ???? Stores energy and helps absorb vitamins.
   ???? Vitamins & Minerals (Health): Found in fruits, vegetables, and dairy. ????‍⚕️ Keeps your body strong and healthy.
   ???? Water (Vital): Essential for all body functions like digestion and temperature control. ????

2. ???? A Balanced Diet

   Eating the right balance of carbs, proteins, fats, and vitamins to stay healthy! ????????????

3. ???? Digestion

   The process where food is broken down into nutrients the body can absorb. Important for getting energy!

4. ????‍⚕️ The Human Digestion System

   Mouth: Food is broken down by chewing. ????
   Stomach: Acid and enzymes break food down. ????
   Small Intestine: Nutrients are absorbed into the bloodstream. ????
   Large Intestine: Water is absorbed and waste is formed. ????

⚛️ Elements ????

1. ???? Elements

   Basic building blocks of all matter. ???? Examples: Oxygen (O), Carbon (C), Iron (Fe).

2. ???? Atoms and Molecules

   Atoms: The smallest particle of an element. ????
   Molecules: Two or more atoms bonded together, like H2O (water). ????

3. ????️ Metals and Non-Metals

   Metals: Shiny, conductive, and bendable (e.g., Copper, Iron). ⚡
   Non-Metals: Brittle and non-conductive (e.g., Oxygen, Sulfur). ????

4. ???? The Periodic Table

   A chart where elements are organized by atomic number. ???? Elements in the same column share similar properties! ????

5. ???? Compounds

   Compounds are formed when two or more elements are chemically combined (e.g., H2O). ????‍????

6. ???? Properties of Compounds

   Compounds have different properties from the elements that make them. For example, salt (NaCl) is not like sodium or chlorine! ✨

7. ????️ Forming Compounds

   Chemical reactions combine elements to form compounds (e.g., Sodium + Chlorine = Salt (NaCl)). ????

???? Light ????

1. ???? Nature of Light

   Light travels in waves and can act as both waves and particles. ????

2. ???? Shadows

   Shadows form when light is blocked by an object. ????️ Think of when the sun creates a shadow behind you! ????

3. ???? Reflection of Light

   Reflection: Light bounces off surfaces (like mirrors). ???? The angle of incidence = the angle of reflection!

4. ???? Refraction of Light

   Refraction: Light bends when it passes through materials like water. ???? Try it with a pencil in water!

5. ???? Dispersion of White Light

   White light can be split into colors using a prism. You get the rainbow! ????

6. ???? Coloured Lights

   Light has different wavelengths (e.g., Red light = long wavelength, Blue light = short wavelength). ❤️????

???? Magnetism ????

1. ???? Magnets and Magnetic Materials

   Magnets attract materials like iron, nickel, and cobalt. ???? They create a magnetic field. ⚡

2. ???? Magnetic Field

   The magnetic field surrounds magnets and affects objects near them. ???? North and South poles.

3. ⚡ Electromagnet

   An electromagnet is made by passing electric current through a coil. The more coils, the stronger the magnet! ⚡

4. ???? Uses of Electromagnet

   Electromagnets are used in motors, MRI machines, cranes, and speakers! ⚙️
