Science experiment chart

Task 2 and Task 3

Compounds	Method	Observation of reaction	Why does it react that way
Baking soda Vinegar	A teaspoon of the baking soda was placed in a cup. 3 teaspoons of vinegar were then placed into the cup.	The mixture bubbled, fizzed and overflowed.	Why does it react like that ? It reacts that way because the acid in the baking soda reacts to one of the chemicals in the vinegar.
bleach Baking soda	1/2 cup of baking soda is added to a typical laundry load with bleach	It fizzes a little but it also becomes a better cleaning product.	It has that kind of reaction because the baking soda has a sort of acid in it that reacts to a chemical in the bleach.
Lemon juice Baking soda	3 tbsp of lemon juice and 2 tsp of baking soda in a glass and watch the reaction.	The reaction was that it bubbled/fizzed up but it is good for sores .	In lemon juice there's a percentage of citric acid and the acid in the baking soda clashed with the acid in the lemon juice.
Dish soap Vinegar	Place a 1\4 of vinegar and dish washing liquid in a spray bottle put the lid on and shake.	It just ended up bubbling and is good for cleaning products.	It didn’t fizz this time itn only bubbled because in the dish soap there isn’t any baking soda or citric acid
Lemon juice Sugar	Put 2 tsp of lemon juice in 3 tbsp of sugar in a cup.	There was only a little bit of fizz this time but it made a good ointment.	It  didn’t react like the rest because the sugar isn’t the same as the baking soda because it has no acid in it .

2. No Baking Powder
3. No milk
4. With Lemonade
5. With Baking Soda

• Draw up a chart to record your findings
• Make 4 recipes using the following quantities

Recipe:

• 1/2 cup Edmonds standard flour
• 1 tsp Edmonds baking powder  or 1 tsp baking soda                                            
• 2 tsp butter
• 1/4 cup milk, approximately or 1/4 cup lemonade

Lemonade scone Recipe:

• 1/2 cup Edmonds standard flour
• 1 tsp baking powder                                                
• 2 tsp butter
• 1/4 cup lemonade

No butter Recipe:

• 1/2 cup Edmonds standard flour
• 1 tsp Edmonds baking powder  or 1 tsp baking soda                                            
• 1/4 cup milk

Baking soda Recipe:

• 1/2 cup Edmonds standard flour
• 1 tsp baking soda                                                     
• 2 tsp butter
• 1/4 cup milk,

Materials:

1. Plate

2. Spoon

3. Measuring cup

4. Milk

5. Butter

6. Flour

Process

Step 1: Get your ingredients

Step 2: Measure ¼ cup of flour and place in your bowl.

Step 3: Get two tsp of butter and put it in your bowl.

Step 4: Then pour ¼ of a cup of milk in to your bowl.

Step 5:  With your final ingredient get 1 tsp of baking powder and place it in your bow.

Step 6: Then mix it all together until it looks and feels like dough.

Step 7: Then make it into twos and place it on the tray.Then put it into the oven.

Findings:

TRIAL NUMBER:	COLOUR	TASTE	HEIGHT (CM)
1. NORMAL	golden	dry	47 mm
2. WITH BAKING SODA	Dark brown	Very bitter	34 mm
3. NO BUTTER	white	dry	48 mm
4. WITH LEMONADE	brown	bitter	33 mm

Conclusion:

Materials

1. Lemonade
2. Baking soda
3. Flour
4. Bowl
5. Spoon
6. Butter

1. All of the scones were baked at 200 Celsius.
2. The scones were all bake for 10 minutes.But they do not come out all the same.

Skittle expirement

Aim: To separate colors by using the process of chromatography.

Materials;

1. Petrie dish 

 

2. Water
3. Skittles
4. Petrie tray 
5. Jug 


Process
Step 1: Grab your petrie dish and place it on a flat surface

Step 2: Get your skittles and place them in your petrie dish.In 5 equal parts.

Step 3:Get your water and pour it over your skittles so its just covering them.

Step 4:Wait until the skittles are dissolved


Findings: Write about what happened. The colors and how they fade into each other.

Reflection: What have I learnt from this experiment? That the colors do not join straight away.

What did the colors do ? They did not mix at first but if you bumped them they would mix.

Did the colors mix together ? If you bumped them.

Why or why not ? Because they got bumped and they did not because the water was still.

Rainbow Paper

Aim: To separate colours by using the process of chromatography.

Definition: A technique for separating the different parts of a mixture / solid using liquid.

Rainbow paper

Materials;

1. Felt Pens

2. Ruler

3. Pencil

4. Liquid

5. Container

6. Tissue Paper

Process:

Step 1:Rule the tissue paper. 2 cm from the top and 1 cm from the bottom

Step 2:Pencil line the marks.

Step 3:Add dots out of the 3 felt colors on the pencil line of 1 cm  

Step 4:Then fold the Tissue paper on the 2 cm line. 

Step 5:Then place the tissue on the side of the container

Step 6:Pour a little bit of liquid in.

Findings: Write about what happened.

Reflection: What have I learnt from this experiment? That black has blue yellow and red inside of it.

Talia and Shontae

Dirty water experiment

Aim: To make a filtration plant using household materials.

What is filtration?

Filtration is separating solids from liquids by adding a medium through which only the liquid can pass. 

Examples are:

1.  kidney                                   
2.  Jug 
3. Tea bag 
4. Swimming pool

Materials

1. Stones/Pebbles 

2. Container 

3. Sand

4. Dirty water

5. Funnel

6. Scissors

7. Filter paper

8. Cup 

Steps 

Step 1

Cut a bottle in half if you do not have a funnel.

Step 2

Put the top half of the bottle upside down on the top of the other half of the bottle.If you have a funnel you could place it on something like a beaker or a shape that´s like a cylinder.

STEP 3

Make a cone with some filter paper by folding it.Place it on the funnel.Add half a cup of sand first and pack it in.Then add half of cup of pebbles on top of the sand.

STEP 4

Get 1 cup of dirty water and pour it into your funnel and watch the reaction.

Reaction 

Its starting to drip but the water got more clear when it came out the funnel.Because it got filtered by all the stuff in it.We didn't get any clumps.
