Chemical reactions

Today in hurumanu science our aim was to see how to chemicals that you could find at your house would act if you mixed them together.


7/8 Bh and 7/8 Tz have been working on a Home Chemistry as our hurumanu topic this term. We mixed to simple chemicals that you can find at your house and then we mixed them and we watched what there reaction was. The equipment we used in this experiment was vinegar, baking soda, and measuring cups the first step we done was we placed some baking soda in the cup then we pored some vinegar into the cup also and watched what happened. As I thought the vinegar and baking soda had a reaction they made a mixture that would fizz up and leave the cup, then we tried it a different way this time we put the vinegar in the cup first and the the baking soda, because we wanted to see even if its put in a different way would it still make the same effect.

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.

THE PLAN:
task one:

1.What do we want to find out?
We need to find out why does the ocean not freeze so we are going to be experimenting buy seeing how much water and salt you need in a cup that you put in a freezer overnight and see if it freezes and then we need to expand of that.

2.How will we find out?
we are going to test five different cups that have different amount of salt and water in each.

3.How will we record your findings?
Right it down or take photos.

4.what equipment will we need?
cup, water and salt.

5.how long will it take?
three to four days.

THE PRODUCE:
task two: What are the steps that we will use to make the experiment?

1. Get four cups of water and put different amounts of salt and water in each cup.
2. Put each cup in the freezer overnight and then the next day check on them and see the results.
3.Then record you results.

THE PROCESS:
task three:  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. Beakers
  2. Water
  3. Measuring spoons or cups
  4. Salt




Dirty water experiment

Aim: To make a filtration plant using household materials.

What is a filtration?

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

Examples are:

  1.  Teabag
  2. swimming pool
  3.  kidney
  4.  coffee plunger/coffee filter

Materials

1.Dirty water
2.Sand
3.Filter paper
4.Pebbles
5.Water bottle
6.Scissors
7.Funnel
8.Coffee filter

Process - ( use verbs or doing words in each step )


Step 1

Cut the bottle in half.

Step 2

Put the top half upside down inside the bottle.

STEP 3

Add layers of filter then add your sand/pebbles.

STEP 4

Get 1 cup of dirty water.

STEP 5
Pour dirty water into the filter inside of the upside down bottle.

Measurements 

When my group did this experiment we successfully did every step but when we were watching it enter the bottom bottle it did clean out a little bit but it wasn't clean enough to be able to drink.

CARR values

CARR values

We had to make a play, skit or anything we could use to show the value we had to use.
My group had respect as our subject in my group there was Clayton, Tj, Danielle, Jrey, Danny and me

*what value did you use
My group and I were doing respect.

*what did your group make
My group and I were making a video

*how well did you work together
We worked okay but sometimes we got offtrack

*were you successful
Yes we were because we got all the worked finished and we all agreed and like the video that we mad

freeze frames!

Today in drama class we got into groups and we had to come up with a position that we could pause in that explain what mad us happy and sad so me and my group done a freeze frame of basketball  because that's what made us happy, So thought of a position we could do. A freeze frame is a single frame forming a motionless image from a video or photo.
                                        This is our position we came up with hope u like it.

home chemistry

today me and Tamani worked on 10 different chemicals you could find around your home.
we where looking to find all there different scientific names, this is our work that we produced.

Aim: looking at 10 household chemicals.


Equipment:                              


Common name: chemical name:
1.Salt (Sodium chloride)
2. Surf (Sulphate)
3. White vinegar (Acetic acid)
4. Baking soda (sodium hydrogen carbonate)
5. Baking powder (sodium hydrogen carbonate)
6. Cleaner (potassium hydroxide)
7. Detergent (Sulphate)
8. Lemonade (Citric acid)
9. Sugar (Sucrose)
10. Citric acid (hydroxypropane)


foam, rupture, mixture, baking soda, vinegar
