Observing Reflection in Curved Mirrors

Concave Mirrors:
Concave mirrors have the shiny surface on the inside of the curve. When looking at a tablespoon, the bowl of the spoon is concave.

Convex Mirrors:
Convex mirrors have the shiny surface on the outside of the curve. When looking at a tablespoon, the back of the spoon is convex.


Aim: To investigate the reflection of light rays in concave and convex mirrors.
Method: 1. Set up ray box, triple-slit ray slide and power supply.
2. Place the mirrors on your book as indicated below. Place the ray box at the top of the page and shine the 3 rays of light at the mirror.
3. Ensure that the middle ray of light is hitting the mirror at a 90 degree angle.
4. Carefully trace the direction of the three incident rays and the three reflected rays.

Science

Findings: The angle of incidence is the same as the angle of reflection.

Aim: To investigate how light behaves when it hits a plane (flat) mirror




Method

 1- Collect a ray box, power supply and single slot ray slide from your teacher, and set them up to produce a single beam of light.

 2- Place a plane mirror on the diagram of the protractor as described below.

3- vary the angle of incidence and record the angle of reflection in the results table.

GOOD FATS VS BAD FATS

  • Small amounts of trans fats naturally occur in dairy products, beef, veal, lamb and mutton. 
  • Monounsaturated fats can lower bad cholesterol and increase good cholesterol. 
  • High levels of bad cholesterol can lead to heart disease so monounsaturated fats can protect the heart.
  • Saturated fat can raise bad cholesterol levels.
  • Trans fats are so bad that some cities have banned them from restaurant foods.

SUGAR



Sugar can effect your Brain, Mood, Teeth, Joints, Skin, Liver, Heart, Kidneys, Body Weight and much more. Sugar consumption also promotes inflammation in the brain, gut, and body, which can lead to chronic physical and mental health problems.

English

Lately in English I have been working on my static image, mine is mostly about the quote from the book Abomination "You Can't Keep Secrets From God". I am still in the design process for this and so far I have drawn a bible and a cross on the top and I will be adding the quote to the image today and also adding colour.

Protein- any of a class of nitrogenous organic compounds which have large molecules composed of one or more long chains of amino acids and are an essential part of all living organisms, especially as structural components of body tissues such as muscle, hair, etc and as enzymes and antibodies.

Studies show that eating a high-protein diet has a number of health benefits. The benefits of protein in your diet not only help you maintain and lose weight, but protein also works to stabilise your blood sugar levels, improve your ability to learn and concentrate, reduce brain fogboost your energy levels, support your muscles and bones and support the absorption of important nutrients.

In almost every food
High-protein diets may promise weight loss, but it may only be short term. Excess protein is usually stored as fat while the surplus of amino acids is excreted. This can lead to weight gain over time, especially if you consume too many calories while trying to increase your protein intake.

What happens if I don’t get enough protein?

Protein deficiency is mostly caused by essential amino acid deficiency. Deficiency of each of the nine essential amino acids causes distinct symptoms. Deficiency of any of them prohibits the synthesis of a variety of proteins.  Without protein, the human body cannot function normally.
Early signs of protein deficiency include:
  • Muscle loss (unexpected weight loss)
  • Fatigue
  • Depression
  • Uneasiness (anxiety)
  • Anaemia
