Black holes

I wanted to find out about the black hole and how they form.
Why did I choose to do black holes? Because I want to learn about something I did really know about.
What did you find interesting about it? Nothing can escape the gravitational pull not even light.

What happens to food?

Ingestion:

• When enters your mouth. this is called ingesting food.
• Chew food is called mastication
• swallowing food
• The teeth that you chew is called a molar.
• The teeth that your trip and tear food with called canines.
• The teeth that you cut with is called the incisors.

.

• The food gets "pushed" down the oesophagus to the stomach by waves of muscle contractions that move the food to different processing stations.  This process is called peristalsis. It starts when a bolus of food is swallowed.

Growing Crystals

Aim: I want to find out how to make crystals form in a super solution.

Equipment:

• A supersaturated of Sodium Acetate 
• A seed crystal of sodium acetate 
• Bunsen burner
• Heat Mat 
• Boiling tube 
• Scissor Tongs
• funnel 
• filter paper 
• Small Beaker 

Method 

1. Add the supersaturated Sodium Acetate in the filter with filter paper
2. the sodium acetate. make sure the test tube is facing the wall
3. take the test tube in and out ever 10 seconds
4. put the test tube into a beaker with cold water after all of the crystals are gone.
5. wait for about five minutes for the Sodium Acetate to cool down.
6. get one crystal/crystal seed. put one crystal/crystal seed into the test tube after it's cooled down. Something will happen

Discussion:

I learnt that a crystal seed is just one crystal.

I thought it looks really cool in the end when I put the crystal in it.

I like how it doesn't take that long to do this 

Dilution

Aim:
I want to investigate how to dilute a solution.

Equipment:
Test Tube Rack
Test Tubes
10mL measuring cylinder

Method:

Fill measuring cylinder with 10mL of water

Add 10mL of water to a test tube

Add 9mL of water to 5 more tests tubes.

Add a small spatulaful of Potassium Permanganate to the first 10mL test tube of water

Add 1mL of the dark purple Potassium Permanganate into the second test tube.
