Chromatography/ With Skittles and water

Today in home chemistry we did an experiment with skittles and water. It was pretty fun and this is the third time I did this experiment.

This is what we needed

Materials;

1. A container
2. Some water
3. Skittles
4. A lid for the container
5. A device to take pictures
6. Also a device to make a blog post

Process:

Step 1: Get one of those little container and the skittles were already in the container
Step 2: Sit back down and wait for the teacher to pour the water in your container
Step 3: After the teacher has put the water in wait for something to happen
Step 4: Take a picture of the skittles in the water when it just starts to do something
Step 5: Wait like 5 minutes then look at the container and take a picture of what has happened
Step 6: When your done make a blog post about what happened

Findings: Write about what happened. When we first put the water in with the skittles it just started to show the colour just around the skittles and we had to take a picture of the skittles of when this happened. Then a few minutes later the container was covered with the colours from the skittles.

The pictures:

Reflection: What have I learnt from this experiment? That even if you don't have much time and you want to do a fun experiment you can do this one. It takes less than 10 minutes and it looks cool when your done with the experiment.

What did the colours do? They went through the water but they didn't mix together.
Did the colours mix together? Not until I moved the container.
Why or why not? No because I think the skittle colours we in its own space in the container until I waked over to tip the water out.

Hope you like my experiment, bye

Water and Salt Experiment

Today in home chemistry we are learning about, how much salt in water will help it not freeze in the freezer overnight. Here is what I found out.

The Plan.

Task 1; Read the question carefully and write the answer to these questions. 

1. What do we need to find out? How much salt in water will not make it freeze in water
2. How will we find it out? Try our method out and if it doesn't work it doesn't work
3. How will we record what we find? In our books or on our chromebook
4. What equipment do we need for the experiment? A cup of water, salt and a freezer
5. How long will it take? Overnight is it works the first time but it i doesn't work maybe a few nights

The Procedure

Task 2: What are the steps that you will take to make the experiment? 

List them in 6 steps.

Step 1; Get a cup with water in it and get some salt
Step 2: Get some spoons to put the salt in the cup
Step 3: Put the salt in the cup
Step 4: Carefully put it in the freezer and leave it overnight
Step 5: Check it the next morning the water froze or not
Step 6: If it didn't work try again

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.

These are the pictures I drew.

Sorry you can't really see them

Chromatography/ With coloured pens

Today in home chemistry we are learning about Chromatography. The Chromatography we are learning about is putting felt pens on a piece of paper then putting the end of the paper in water and putting skittles in water and waiting for the result. 

Materials;

1. A piece of chromatography paper

2. A pencil and ruler 

3. A cup of water

4. Felt water based pens, we did red, black and green

5.  A Chromebook or I pad to get photos

6. A Chromebook or i pad to do a blog post about it

Process:

Step 1: We got the chromatography paper and we write lines on each end, one end was 1 cm and the other end was 2 cm

Step 2: We put 3 dots with 3 colours on the line

Step 3: After that we put the paper in the water and let it sit

Step 4: We got our Chromebooks out to take some photos

Step 5: We got some photos on our camera

Step 6: We had to start doing a blog post about what we did

Findings: Write about what happened. At the start it was just wet paper but after a while a few different colours came out of just the 3 colours. I can't remember exactly what the colours were but I knew there was about 6 or 7 on the 1 piece of paper. After that we let it sit and moved on to a different experiment

Reflection: What have I learnt from this experiment?

When We Have a Reliever

Today with our reliever I was finished what the class had to do that was on the board so I asked my Mr White if I could sit with my friends outside and read my book. After I got bored of reading my book I asked if I could go on Mathletics and Mr White said yes. When we have guest in our class I should be quiet when they are talking what I always do when someone new is in our class and someone who has been in our class for a while as well. Also when a guest is in our class when they ask you questions about what you are doing you should tell them what you are doing.  Next time I will not ask to sit with my friends when I finished my work. Also I won't ask to go outside with my friends.

Hello readers today I'm going to be making a blog post about home chemistry las week we went and to mr palmers  class and mix baking soda and vinegar here is a picture of what he did and here is also a step by step.

Please read it. 

Please comment on my blog post bye.

CARR values group

Last week we got in groups and made a skit, dance, rap or video to show the class. At the start of last week my teacher made the yr 8 girls and boys went in two lines. Also the same for the yr 7s. After we got in our lines our teacher got the first yr 7 boys and girls in the lines got in the same group. The same for the yr 8s. So the people in my group were Dannielle yr 7, Tai, Tj, Clayton, and Danielle yr 8(me). When we got in our group we got a big piece of paper to write ideas on and what we were going to do. We came up with thinking of a skit we could film. The roles were Clayton was the caemra man, Tj and Tai were the Nerds and me and Dannielle we the bully's. It was so hard not to laugh but somehow we did it with only a tiny bit of laughing for like a second but that's better than the first time where we were laughing most of the time.

The next day we practiced and shot it for the first time but that wasn't the one we were going to show the class. We had 10 minutes or something like that to practice filming. So the next time we worked on our project it was a different day and that was the day we finished. So the class had a 30 minutes to finish filming and show our teacher. Since we knew what we were doing we just filmed it again once or twice because of us laughing. After we finished we showed the teacher and she said just upload it to emails and send it to her. Right after we did that we were done and just doing our other work we had to do

Home Chemestry Week 2

Last week my class and Miss Tozers class were doing home chemistry. We do home chemistry and drama at different times and days. Today day for home chemistry, we had to find the chemical name for different items and if you didn't have a device  you budded up in a pair or a group of 3. I didn't have a device neither did Danni so we budded up with Reisha. So our group was Reisha, Danni and I.

What we had to figure out in science this week is.....

The process / what we had to do:

So the first chemical name from our list was salt . The chemical name for salt is Sodium Chloride, the next thing was surf we couldn't find anything different to something else on our list so we put laundry detergent. After that was white vinegar the chemical name for that was Acetic Acid, the next thing was baking soda and the chemical name for that is Sodium Hydrogen Carbonate and that's the same as baking powder which is after baking soda.

Next was cleaner and the chemical name is  Muriatic Acid. The thing that had the same thing as surf was detergent and the chemical name is Carboxyic Acids. Next was lemonade but there was no chemical name so we did the biggest ingredient which is Glucose H20. After was sugar and the chemical name is Glucose, the last thing was citric acid and the chemical name is Anhydrous.

Hope you like our groups research, bye
