Food Scientist + How to Make Sherbet

Food scientist= studies food

• Look at: texture
• Taste 
• Causes of food going off/bad
• Making new foods.
• Best ways to package food
• Shelf life (How long it will last in good condition)
• Evaluate the food
• Interaction between ingredients used (When you add the ingredients together)
• Improving + changing the flavors
• The affect of bacteria---
• Spoilage of the food, causing illness
• Ways to preserve food
• Checking how cooking effects the ingredients

Making sherbet

Ingredients-

1. 1/4 cup of icing sugar
2. 1/4 teaspoon Raro
3. 1/4 teaspoon citric acid
4. 1/4 teaspoon tartaric acid
5. 1/4 teaspoon baking soda

Now add together in a plastic bag, mix and enjoy!

Evaluation

The sherbet (I used raspberry raro) was sweet with a slight hint 

of sourness, in most areas. But in the bottom, there wasn't much

 raro, which may have been caused by not enough mixing.

Explode/Implode and Sea Saws

The first photo is with no water and cold.

The second is with hot water and lid on.

And the third is with no water, lid on and cooled.

1. Inside and outside forces acting on the bottle are equal. => Normal shape
2. Hot forces acting on the inside are greater than the outside. => Bottle bulges
3. Hot water erupted. Lid on. Cool under cold water. Force acting on outside of bottle is greater than force acting inside.

Why?

Air pressure (a force) is greater. Air particles have more energy of push, or are "harder"against the bottle.

1. If two people were on a sea saw and are o equal weight where  do they need to sit on the saw to balance it? One on each end.
2. If 1 person is heavier, the heavier person needs to sit closer to the middle, and the lighter person on one end.

Note: Each person's weight is a force pushing down on the see saw.

Isaac Newton, G' forces, Concorde plane verse Cargo plane and The Bends

Isaac Newton

Isaac Newton wrote three laws of motion in 1686, and presented them in "Principia Mathematica Philosophiae Naturalis" . His first law states that every object will remain at rest or in uniform motion and in a straight line unless compelled to change it's state by the action of an external force.

Isaac Newton's first law of motion, Inertia: An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

Isaac Newton's second law of motion: Acceleration is produced when a force acts on a mass. The greater the mass the greater the amount of force needed.

Isaac Newton's third law of motion: For every action, there is an equal and opposite reaction.

Isaac Newton was born on the 4th of January in 1643 in Woolsthorpe-by-Colsterworth in the United Kingdom.

Isaac Newton came up with the idea that everything that goes up, must come down. (Basically everything comes down to Earths surface)

G' Forces

G-force stands for either the force of gravity on a particular extra-terrestrial body, or the force o acceleration anywhere. It is measured in g's, where 1 g is equal to the force of gravity at the Earth's surface, which is 9.8 meters per second, but in space, astronauts experience unusually high or low G' forces.

The G' force of an object is its acceleration relative to free fall. This G' force can be seen on roller coasters and other amusement park rides. When the coaster goes down a steep drop or hill, you are pushed back into your seat because of G' force.

Concorde vs Cargo planes

So what is the difference between a Concorde plane and a

 Cargo plane? Why is the Concorde so fast? Here are the answers.

• The Concorde is the only commercial passenger plane that travels faster then the speed of sound. Other passenger planes do not
• The Concorde plane has a special pointed cone nose to break through sound barriers
• Almost any commercial aircraft's can break sound barriers with a simple dive. Easy. But the Concorde was designed to break sound barriers with out damaging itself.
• The engines were designed for high speeds. At low speeds, the Concorde's engine would be extremely inefficient, burning up to two tonnes of fuel just taxiing on the run way.

The Bends

The bends is a painful condition that occurs in scuba divers when they ascend too quickly, or in aviators who fly at high altitudes. Also called decompression sickness, the bends results when bubbles from dissolved gases within the blood or tissue because of rapidly decreasing pressure.

The bends can cause excruciating pain, and can even be lethal.

High Impact Kete Tasks: Motion

Motion

In Physics, motion is explained as a change in position of an object overtime. It is described in terms of: Displacement, distance, velocity, acceleration, time and speed.  If the position of a body mass is not moving or in motion, the mass is said to be at rest, motionless, or immobile.

An objects motion cannot change unless acted upon by a force. As there is no way to tell, you can never truly determine when an object is in absolute motion. 

This can be seen when walking, running, biking, or any other change in position.

High Impact Kete tasks: Unbalanced Forces

Unbalanced Forces

An unbalanced force is when there is a single force that is not being balanced by a second force a that is of equal magnitude and in the opposite direction, and causes a change in the object's motion.

When balanced forces act on an object at rest, the object will not move.Where as if an unbalanced force acts on an object at rest, it will cause the object to accelerate, as there is no other force of equal strength going opposite to stop it. 

This can be seen when something accelerates, and there is no other force there to stop or slow it down, like kicking a football.

High Impact Kete tasks: Balanced Forces

Balanced Forces

Forces only ever occur in pairs and can be either balanced or unbalanced. Balanced forces are two forces acting in opposite directions on an object, and equal in size. 

Anytime there is a balanced force on an abject, the object stays still or continues to move at the same speed and in the same direction. An object is only said to be acted on by an unbalanced force when there is an individual force that is not being balanced by a second force of equal magnitude and in the opposite direction of the first force. 

This can be seen and demonstrates by having an object, and one person pushing it towards the other on each side. This is seen when you push something, but there is a second force equal in magnitude trying to stop you

High Impact Kete Tasks: Push and Pull

Push and Pull

To push something, is to forcefully move an object away from the source of energy. To pull somehing is to force it towards the source of energy.

Formally stated, Isaac Newton's third law is: For every action, there is an equal and opposite reaction. This meaning in every interaction , there is a pair of forces acting on the two interacting objects. The size of the force acting on the first object is equal to the size of the force on the second.

This can be seen when picking up or moving any object

High Impact kete Tasks: Acceleration

Acceleration

Acceleration is the increase in speed or rate, or the rate of change of velocity per unit of time. An objects acceleration is the net result of any and all forces acting on the object, as described in Isaac Newton's second law.

Isaac Newton's second law- Acceleration is produced when a force acts on a mass. The greater the mass (of the object being accelerated) the greater the amount of force needed (To accelerate the object)

It states that the acceleration of an object relies on two variables: The net force acting upon the object, and the mass of the object.

Acceleration can be seen when we increase our speed in a race, or when driving a vehicle.

High Impact Kete Tasks: Mass

Mass

The mass of an object is the a measure of an object's resistance to acceleration, sometimes also called "Inertia". For instance, a mountain has more mass then a rock. Mass shouldn't be confused with the related but quite different concept of weight. 

A large mass, like Earth, will attract a small mass like a human being with enough force to keep the human being from floating off into space. This is called "Mass attraction"and is another word for gravity.



We can see mass when weighing two different objects using a scale.
