Investigating Refraction Through Lenses

 Aim: 

To investigate how different types of lenses refract light.

Equipment:

 Triple-slit ray slide, power supply, a concave lens and the convex lens.

Method:

1. Set up the ray box, Triple-slit ray slide and  power supply

2. Place the convex lens in the space below. Place the ray box at the top of the page and shine the three rays of light at the tens. Make sure the central light of ray hits the lens at 90degrees as indicated in the diagram.

3. Carefully trace the direction of the incoming and refracted rays.

4. Repeat using the concave lens

Science

Investigating Refraction- Bending light

Aim: 

To investigate how light is affected by changing the substance it is travelling through.

Equipment: 

Ray box, power source, glass perspex block, single-slit ray slide.

Method:

Collect the equipment from your teacher, and set them up to produce a single beam of light.

Part A: Going from Air to Glass

1. Place the glass block in the shaded area below 

2. Place the ray box at the top of the page and shine the beam so it travels along the 10degrees line to the centre of the protractor (this is your angle of incidence, 1degrees)

Concave Mirrors:
Concave mirrors have a 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 the light rays in concave and convex mirrors.

Method:
1. Set up your ray box, triple-slit ray slide concave and convex mirrors, power supply
2. Place the mirror 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 90degrees angle.
4. Carefully trace the direction of the three incident rays and the three reflected rays.

Sciece

Finding:

 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-slit ray slide from your teacher, and set them up to produce a single beam of light.

2. Place the 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:
Olives, salmon, and walnuts have good fats.
Good fats are monounsaturated and polyunsaturated.
Monounsaturated fats can lower LDL or bad cholesterol and in increase SDL and good cholesterol.
Monounsaturated fats can help protect the heart from heart disease.

Bad Fats:
teak an ice cream both have bad fats.
Bad fats are saturated and trans fats.
Read meat, Butter, Chicken with the skin, and milk.

Some foods that contain these unhealthy fats are almonds, pecans, and seeds like pumpkin and sesame and also avocados. Omega 3 fats can help lower bad cholesterol and prevent heart disease and stroke. You can get omega 3 fats from eating fish up to three times a week or from liquid oils. Margarine is better to use rather than butter.
Our bodies make enough saturated fats as it is and we don't need to eat/ add anymore.

Define 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.

What Does Protein Do In The Body

Hair and nails are mostly made of protein. Your body uses protein to build and repair tissues. You also use protein to make enzymes, hormones, and other body chemicals. Protein is an important building block of bones, muscles, cartilage, skin, and blood.

What happens if u have to much protein

Excess Protein May Fuel Weight Gain, Yeast Overgrowth, and Cancer. There are a number of reasons why I believe it's prudent to limit your protein intake

What Happens If You Don't Get Enough Protein

If carrying your groceries from your car to your refrigerator feels like a challenge, your diet may be to blame. “When you don't eat enough protein, the body will start to break down stored proteins in the form of muscle and other tissues.

Where Do You Get Protein From

Seafood. Seafood is an excellent source of protein because it's usually low in fat. ...

White-Meat Poultry. 

Milk, Cheese, and Yogurt.

Eggs. 

Beans. 

Pork Tenderloin. 

Soy.
