AIM: DESIGN AN EXPERIMENT THAT TESTS THE AMOUNT OF SALT THAT MUST BE IN WATER BEFORE IT WILL NOT FREEZE WHEN LEFT OVERNIGHT IN THE FREEZER.

Task 1.    

1. What do we need to find out?

How much amount of salt that must be in the water.

2. How will we find it out?

  I want to know how long it will take to freeze.

3. How will we record what we find?

Video it to see how it work or blog it.

4. What equipment do we need for the experiment?

Salt, water, freezable glass

5. How long will it take?

Leave it until overnight.

Task 2:

Step 1: Get a two glass to put the ingredients.

Step 2: Get a salt and a water in a separate glass.

Step 3: Put water in the two glass.

Step 4: Put salt in one glass and put more salt in the other glass

Step 5: Mix the salt in the water and put it the freezer overnight.

Step 6: Take the glasses out of the freezer then compare the two glasses to see which one froze.

The Process:

Task 3:Draw on a piece of A4 paper the 6 steps that you will use to test the amount of salt in water before freezing. When we are making drawings in science  it needs to be labelled clearly, kept tidy and named. Once you have completed the drawing it must be photographed and uploaded to your blog.

In your drawing you will use:

1. Beaker

2. Water.

3.Measuring spoon/cups

4.Salt.

My drawing and my answer:

                      

10 Mystery ingredients.

Aim: To learn the names of 10 household chemicals, their elements, and reactions with other substances.

  Equipment:

1. Dishwashing Detergent

2. Lemon

3. Salt

4. Vinegar

5. Sugar

6. Air Freshener

7. Onion

8. Lemonade

9. Bleach

10. Baking Soda

   

  So for this one we have to research if that image is a solid, liquid or a gas and research what is the chemical Ingredients.

Name	Chemical Ingredients	Image	Solid/ Liquid/ Gas?
Lemon	Citric Acid.		Liquid
Salt	Sodium Chloride		Solid , soluble
Vinegar	Acetic acid.		Liquid
Sugar	lactose		soluble
Air Freshener	Phthalates, alpha-pinene		Liquid, gas
Onion	acid		gas
Lemonade	High fructose		liquid
Bleach	Hydrogen peroxide		liquid
Baking soda.	Sodium bicarbonate		soluble

    Also the exciting part is when Mr Palmer show a experiment.( Sorry don't have any picture of it)

  

  Materials: 

Baking soda

Vinegar

Water bottle that is empty 

And a Ballon.

 Method of the vinegar and the baking soda:

Put 12 to 1 ratio of vinegar and carefully put it in the container where the baking soda is meant to be placed in.

Observation of reaction:

When you adding the vinegar to baking soda it gives you an immediate reaction. Adding them together the reactions is delayed but then the reaction will fizzes the amount. If you put more vinegar is better but if you don’t put a lot it will not that kinda bit work, a 12 to 1 ratio of vinegar to baking soda it will cause a overload bubbled and fizzed reaction.

Scone..

Scones

Aim: To look at different kitchen ingredients
in scones and their effects.

Make 4 types of scone.
Normal plus 3 others
No butter,
No Baking Powder
No milk
With Lemonade
With Baking Soda
Draw up a chart to record your findings
Make 4 recipes using the following quantities

Recipe: 1st Scone
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

Recipe: 2nd Scone
1/2 cup Edmonds standard flour
1 tsp baking soda                                                     
2 tsp butter
1/4 cup lemonade.

Recipe: 3rd Scone
1/2 cup Edmonds standard flour
1 tsp Edmonds baking powder                                                      
1/4 cup milk

Materials:

1. Plate-to put the scones.

2. Spoon- to mix with.

3. Tray- to place the dough.
4. Bowl-to put the ingredients and mix it there.
5. Paper- To write your initials
6. Pen or a pencil- To use to write you initials
(optional colour of a pen)

Process:
Step 1: Get a bowl to put your ingredients.

Step 2: After you have the bowl go and get ½ a cup of a flour.

Step 3: Then add 1 tsp of baking powder.

Step 4:Then after you’ve put the flour and the baking powder,
now add 2 tsps of butter.

Step 5: When all of the ingredients are in the bowl mix them properly and wait until the texture is dough.

Step 6: After it turn to dough texture go and mould it and shape it into circle.

Step 7: Get a plate to put your dough.

Step 8: When you’ve done it to a shape of a circle go and get the plate that you’ve prepared and put it there.

Step 9: After you place the dough to your plate get a paper and a pen to write your initials,
and when you’ve write your initials and place the initials on the top of the plate.

Step 10: When you’ve done everything go and give to the teacher so they can put it to the oven and bake it.

FINDINGS:

TRIAL NUMBER	Colour	Taste	HEIGHT (CM)
1.Normal	Golden	Dougie and Crummy	It was 4.7 mm
2. No Butter	White & Tan	It dry.	4.5 mm
3.No baking powder
4.With Lemonade.	Brown	It was really bitter	3.7 mm

Conclusion:

For our Science this week we made a scone with another class it was really fun making a scone because you can bake and do some experiment with it. So me and my group make 3 scone but we have to do 4 scone and we don’t have enough time to make the last one because it was almost bell ring, so the 3 things that we make is a different scone like the Normal,No butter and With Lemonade.

The first cone that we made is a normal one so it has all of the ingredients so when it bake the colour change and it turn into a “Golden” colour I wasn’t expecting that the colour will be golden and the normal one raised into 4.7 mm,at the first start I thought it will taste good because the colour was golden and when we taste it was so crummy and uncomfortable to eat because it was so dougie.

The second scone that we made is the No butter so it only has some of the ingredients so the texture for this one is dry and when we bake it... it raised into 4.5 mm and the colour was white and tan, and when we eat it was so hard to break it and it feel like a rock and it taste really dry so I feel like this is the awful one that we made because it was really hard to eat and it was kinda nasty and dry when you taste it.

The last scone that we made is with Lemonade so it kinda look like the no butter but it has different ingredients and for this one when we bake we measured them and this one raised into 3.7 mm and it turned into a brown colour, and the taste of it was really bitter and kinda sour because of the lemonade and it is also has a horrible taste.
