Slam Dunk Paragraph

Hello everyone in this blog you'll see my first Slum Dank Paragraph and it is about what was life in the middle ages.

What was life in the middle ages?

Interestingly life was different for the rich and poor. Rich people like the King & Queen lived in castles, ate lots of food and, showered every day. The poor lived on farms, showered 1-2 a year, did not have enough food and the whole family sleep on the same bed. This is important to know because If you're born poor you're always poor, if you're born rich you're always rich. Life was terrible for peasants.

Diffusion Experiment

Hello everyone today in science/chemistry we talked about Particle Theory and Diffusion and then we did an Experiment.

Diffusion Experiment

Intro: This week on Chemistry we talk about Matter, Particle Theory and Diffusion.

Aim: Investigate if particles diffuse after in hot or cold water?

Hypothesis: I think the particles will diffuse after on hot water because particles move faster from the heat that is applied.

Results: My hypothesis is correct, the Potassium Pomegranate diffused faster is the hot water.

Discussion: The Potassium Pomegranate diffused faster on the hot water because of the temperature. Hot water made the particles vibrate and move faster, on the cold water the particles are cooled down, they can move but slower.

Where the Black Death fits in to History

Hello everyone on this blog it's about history and events that happen at that time.

Evaporation Experiment

Evaporation Experiment 

Intro: We have been learning about Evaporation and how do Evaporation work. Evaporation when the liquid turns into a gas.

Aim: To evaporate Copper Sulfate (Blue Liquid). To separate the mixture.

Hypothesis: I think there will be some blue stuff that will be left behind the solution.

Equipment: 

1. copper sulfate solution
2. 250ml beaker
3. heatproof mat
4. evaporating basin
5. element

Method: 
1. Set up the element.
2. Add 100ml of hot water to the beaker and place on the element.
3. Add copper sulfate to the evaporating basin until it is quarter full.
4. Carefully, place the evaporating basin on the top of the beaker.
5. Turn the element to 8.
6. Heat the solution most of the solvent has been evaporated and crystals of solute are forming.
7. Turn off the element-careful not to touch as will be hot for a long time.

Observation: The water started boiling, then the steam heat up the copper sulfate then the copper sulfate evaporated and left with crystals

Conclusion: I can see that my hypothesis is correct because it left with blue crystals on the evaporating dish

Discussion: When the water started boiling because of the element, the steam from the water heats up the evaporating dish where the mixture of solvent and solute are. While heating up the dish, the mixture started evaporating, and it left with crystals in the dish.  

Distillation Experiment

Distillation Experiment

Separating a Mixture using Distillation

Aim: To separate a solute from a solvent in a solution using distillation.

Hypothesis: On my head, I think what will be left on the conical flask will be the sugars, and the evaporated gas in the cold boiling tube will turn into water.

Equipment: 

• coke zero
• conical flask
• heatproof mat
• a delivery tube and bung 
• element
• tripod
• gauze mat
• retort stand
• boiling tube

Results: 

Observation: 

1. When the coke(solution) started to boil and it starts to evaporate. 
2. You can see condensation on the conical flask.
3. Evaporated coke went to the delivery tube and now it's white like water, then the delivery tube delivered the liquid to the cold boiling tube.
4. The cold boiling tube turns the steam into waters(solvent).
5. What left on the conical flask is the sugar.

Discussion: The solution(coke/sugar) is separated with the solvent using distillation, The solution started evaporating when it starts boiling because we heated it using the element, you can also see condensation inside the conical flask because of the heat contacted with the cool conical flask, and the evaporation travels to the delivery tube. The delivery tube sent the steam to the cold boiling tube (it's cold because we put ice outside it) and turns into a solvent(water). The solution (sugar) is left on the conical flask solid.

Dilution Experiment

Magandang umaga, hapon or gabi bloggers! Welcome to my blog, on Monday what we did in science was very awesome because we did an experiment about dilution. 

                   

                        Dilution Experiment

Aim: To make a dilution series to investigate concentration.

Equipment: A potassium permanganate crystal, six large test tubes, tweezers, a plastic transfer pipette, a test tube rack, 10 ml measuring cylinder. 

Method: 

1. Place the six tubes in a test tube rack. Label the rack with number 1-6.
2. Using the measuring cylinder, fill test tube 1 with 10 ml. Fill the remaining test tubes with 5 ml of water.
3. Using your tweezers, add a single crystal of potassium permanganate to test tube 1.
4. Gently shake the test tube until crystal has dissolved.
5. Using the transfer pipette, carefully remove exactly 5 ml from test tube 1 and pour it into test tube 2.
6. Rinse the transfer pipette thoroughly to ensure that no purple solution remains.
7. Gently shake test tube 2 and repeat transfer process, transferring exactly 5 ml of solution from test tube 2 to test tube 3. 
8. Rinse the pipette again and repeat the transfer process for test tube 4,5 and 6.

Discussion: This was a very great experiment. From test tube to test tube, the liquid became lighter and lighter because of the 5ml potassium permanganate crystal that we drop put inside using the pipette.
