Making a Dilution Series
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 six test tubes in a test tube rack. Label the rack with numbers 1-6
2.Using the measuring cylinder, Fill test tube 1 with 10 ml of water.Fill the remaining test tubes with 5 ml of water.
3.Using your tweezers, add a single crystal of potassium permanganate to test tube one.
4.Gently shake the test tube until the crystal has dissolved.
5.Using the transfer pipette, Carefully remove exactly 5ml from test tube 1 and pour it into the test tube.
6.Rinse the transfer pipette thoroughly to ensure that no purple solution remains.
7. Gently shake test tube two and repeat the 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 to test tubes 4,5 and 6.
Observation: As I was observing the color changing one by one I noticed that the color was getting weaker.
Discussion: We discussed the changing of the colors and how everything changed about the experiment.

Science Experiment
Aim: To investigate the solubility of baking soda ( Sodium hydrogen carbonate) and table salt
( sodium chloride) to see which is the most soluble in water.
Equipment: 250 ml,Teaspoon,Salt,Baking soda, Copeper oxide.
1.Fill the beaker with water
2 Add a scoop of baking soda
3.Stir the solution until all of the baking soda had dissolved.
4.Repeat the steps again but stir until it hasn't dissolved but do it with all three Baking soda, Salt, And copper oxide.
5.Record how many teaspoons off all it took to not dissolve.
Results
Baking soda-5
Salt-9
Copper oxide-0
Discussion: When I put the baking soda in the beaker and stirred it around the first couple times it would dissolve and then I started adding more to one point it wouldn't dissolve same with the salt.
Conclusion:
This experiment showed that some solutes are more soluble than others in a solvent such as water.

Science Experiment
Making A Copper Sulfate Salt
Aim: To produce copper sulfate salt by reacting copper oxide with an acid
Equipment: Copper oxide powder, dilute sulfuric acid, measuring cylinder, 2x 100mL beakers, bunsen burner, tripod, gauze mat, funnel, filter paper, thermometer, spatula, evaporating basin, stirring rod.
Method
1.Add 20mL of sulfuric acid to a 100mL beaker. Heat to 70degrees. Turn off your bunsen.
2.Once heated, use a spatula to add pea-sized portions of copper oxide. Stir for 30secs
3.Repeat step 2 until no more dissolved.
4.Fold filter paper and place in a funnel. Place the funnel in the second beaker.
5.Make sure your first beaker is cool enough to hold and then pour it into the funnel. Gently swirl and allow to filter through.
6.Rinse the beaker and fill with 50mL of water and place on a tripod.
7.Place evaporating basin on top of the beaker and pour some solution in.
8.Gently heat until the solution has reduced by half.
9.Take off heat and allow to cool.
Results and Discussion:When I was observing the second step I notice that the color started to get darker and as we got more into the experiment the experiment we were doing started to get lighter but to be honest I don't really remember what happened but when I came back to school it had turned into a light blue colour and into some sort of crystals.
Conclusion: This experiment involved dissolving a solute in a solvent to create a solution.

19/02/18Savory cases: Last week we made some savory cases that included spaghetti, cheese, onion, corn, and bread.In my group were Cortney and Jaleel.This Practical was to learn how to be able to know where places are and doing a simple task.During cooking or baking.
1.What is Bacteria?
It's a harmful virus that can start a Poisoning disease.
2.What do Bacteria need to survive?
Food, Oxygen, Moisture, Temperature, Time And PH
3.Give three examples of how we avoid spreading bacteria?
1.Firstly wash your hands after playing something or doing your nails.
2.Secondly, don't leave stuff out after two hours.
3.Thirdly tie your hair up

Measuring lessons
Dry ingredients-When measuring dry ingredients you should always level it off with the back of a knife.So all around its even
Liquids-In a Tablespoon or teaspoon always fill it to the top until it levels. If you measure in a measuring mug make sure It leveled with the exact measurements.
Brown sugar-Pat it down with your fingers, then measure it with the back of a knife.
