Making salts II

 The aim for the experiment is to produce copper sulfate salt by reacting copper oxide with acid

The equipment I needed for the experiment was Copper oxide powder, 0.5 mole of dilute, sulfuric acid, 50 mL of measuring cylinder, two 200 mL beakers, Bunsen burner, tripod, gauze mat, funnel, filter paper, thermometer, spatula and a stirring rod

Method 

1. Add 20 mL of sulfuric acid to a 100 mL beaker. Heat the acid until it reaches 70'C and then turn off the beaker 

2. Once heated, use a spatula to add pea-sized portions of copper oxide to the beaker. Stir the mixture for 30 seconds

3. Repeat step 2 until no more will dissolve. Allow the beaker to cool

4. Fold the filter paper and place it in the funnel. Place the filter funnel into the second beaker.

5. Make sure the beaker is cool enough to hold at the top. The contents should still be hot. You may need your teacher to complete this step.

6. Gently swirl the contents of the beaker to mix, then pour into the filter paper in the funnel. Allow to filter though

7.Rinse the beaker you used to heat the mixture previously, and place it back on top of your tripod filled with 50-60 mL of water.

8. Place the evaporating basin on top of the beaker and carefully pour some of the solution from the beaker into the evaporating basin

9.Gently heat the beaker until the solution starts evaporating basin has reduced by half

10. Leave the evaporating basin to cool. Once cool, move the evaporating basin to a warm place where it will not be disrupted (i.e a window-sill) and observe over the next dew days.Blue copper sulfate crystals should form

Observations: I think what would happen during the experiment is that I will mess up.

heart questions

 What have we been learning about?

We have been learning about the circulatory system

Why are we dissecting a pigs heart?

So we can learn what the heart looks like

What are the parts of the heart? Did you see them?

Atrium yes

Ventricle yes

Valve yes

Vein no

Artery no

Did you enjoy the dissection? Why/why not?

No. Because it looked gross and smelled gross

Lemon Power Experiment

Voltage: A

n electromotive force or potential difference expressed in volts.

Current: A flow of electricity which results from the ordered directional movement of electrically charged particles.

AIM: To create voltage out of a lemon

Method: 

Step 1: Roll the lemon out so the inside is liquidy.

Step 2: Stick a piece of zinc and copper into the lemon.

Step 3: connect the lemon up to a voltmeter.

Results: I wasn't there

FACTORIES: Making clothes, cars, electronics, and processed foods creates a lot of pollution. When materials like plastic, cardboard, metal, and cement are made, harmful gases are released into the air and water.

COWS: Cows create a greenhouse gas called methane when they burp and fart. Methane is a greenhouse gas that is 25 times more powerful than carbon dioxide. With about 1.5 billion cows around the world, methane is having a big effect on climate change.

TRANSPORTATION: Most cars need gas or diesel to work. These come from oil, which is a fossil fuel. The carbon dioxide in oil goes into the atmosphere when the car is running and that destroy the trees

LANDFILL: Our landfills are growing and using up more healthy land. When waste breaks down in landfills, greenhouse gases are created, including methane and carbon dioxide. These gases contribute to climate change.

FOOD: We need food to survive, but it creates a lot of pollution. Transporting food by ships, planes, trains, and trucks add carbon dioxide to the atmosphere. Clearing the land for farms and farming practices also create greenhouse gases.

Electricity is a form of energy used to power almost everything in our homes. Electricity can come from renewable sources (water, wind, sun) and non-renewable sources like fossil fuels (oil, and gas). Fossil fuels release CO2 into the atmosphere.

Conclusion





Aim: To make a presentation that investigates different renewable energy's.

Section 1: Title Page

Make a title page that incorporates all renewable energy 's Hydro, Solar, Wind and Wave.

Section 2: Definitions

Define and provide a picture of each energy type.

1. Hydro Energy
2. Solar Energy
3. Wind Energy 
4. Wave Energy

Section 3; Investigate each of the 4 Energy Types.
(Hydro, Solar, Wind, Wave ) 

1. Type:
2. Is it used in NZ?
3. Other Countries that use it?
4. How is it used to generate electricity?
5. Draw and label a diagram of the main parts of the electricity generator? This can be done on paper and uploaded or on a drawing program on your device. I do not want any Internet images or pictures. They must be hand-drawn using a ruler and labelled.

Section 4: Renewable Energy in the future.

List 10 ways that renewable energy will be used in the future to replace our current activities.

Aim: To find out which colour attracts the suns heat.

Hypothesis: I think the black cup will be the hottest because black is an absorbing colour. 

Materials:

1.  cup
2.  thermometer
3.  Chromebook
4.  timer
5.  paper
6. tinfoil

Steps

1.   get someone in your group to get the ingredients.
2.  get the experiment ready.
3.  wait for the teacher to put in the water and give you the thermometer.
4. put the light on 
5. put the timer on
6. when the timer goes off put your results in the finding's box below

Findings:

Time	Cup 1 White	Cup 2 Black	Cup 3 Tinfoil
0	16'c	16'c	16'c
15	18'c	20'c	19'c
30	18'c	24'c	21'c
45	19'c	27'c	23'c

Conclusion

I was right the black cup was the hottest because I know that black is a heat-absorbing colour
