Aim:

I want to see the different indicators

Equipment:

• red cabbage
• beetroot
• tea turmeric
• cranberry juice
• beaker
• water
• Heating plate
• test tube rack
• safety glasses
• hydrochloric acid
• base
• pipette

Method:

1. Chop the cabbage into small pieces until you have enough to fill the small beaker
2. place the cabbage into the small or large beaker then add water
3. then boil it over the heating plate until it boils
4. wait until the colour seeps out of the cabbage
5. repeat the steps with the beetroot
6. then with a pipette get a few drops of the beetroot juice
7. add some drops of beetroot or cabbage into a test tube
8. add some acid and base to each of the test tubes and see what colour it changes into

Discussion:

• What colour did each indicator change in an acid vs. a base?
  The indicator my group used was beetroot and we looked around and wrote down the results of the cabbage, the beetroot changed colour into red in acid and in the base, it turned orange, for the cabbage it turned red in the acid and it turned green in the base
• Why did indicators change colour?
  They changed colour when we added the acid/base as an indicator of the PH level from all the reactions and chemicals
• Were some indicators better than others – if so, why do you think this is?
  Yes because some of the indicators only changed colours slightly where as other indicators changed colours drastically and it was easier to tell. For example, the beetroot changed from red to dark red and thats quite hard to tell the difference but the turmeric changed from yellow to deep red/black.

Conclusion:

• did all your experiments work?
  yes, it was pretty cool
• What could you do to improve next time?
  try adding more acid and base to the beetroot and boiling it longer as well as adding more indicator
• How could you make your results more reliable?
  Adding more acid and base and doing the experiment with a perfectionist so they make us do everything perfectly. For example, counting the number of drops we add to the indicator, and timing the time you boil it.

1. Aim: why did we do the experiment?

Cabbage and beetroot

1. Chop up into small pieces until you have enough to fill 2 cups
2. Place cabbage in large beaker and add water to cover the cabbage
3. boil over Bunsen burner for at least 10 minutes for the colour to leach out of the cabbage
4. filter out plant material to obtain the colour. the liquid is about pH 7 (the exact pH colour will depend on the pH of the water)
5. repeat this for beetroot

for tea

1. put 100ml of water into a beaker and boil
2. turn off Bunsen burner and put in 3 tea bags in beaker
3. remove tea bags when tea is very strong
4. place in small beaker and leave to 1 side

for cranberry juice

1. pour into beaker and leave to 1 side

for tumeric

1. mix 1 teaspoon of tumeric in 100ml cup of alcohol

place in small beaker and leave to 1 side

For the past 2 weeks we have been making wooden knots in hard materials

Discussion:

For our experiment, we went ahead and tested the cabbage’s pH level, we put some water in it and boiled it until it made the water turn purple. Once that had happened we added the red and blue indicators, the red indicator made the cabbage water turn red, while the base indicator made the cabbage water turn green and then yellow. But sometimes in other substances, it changes to a different color, for example, turmeric for the red indicator turned yellow and the blue indicator turned a deep red/black.

The indicators change colors because when they are put in a liquid, depending on if the liquid is an acid or a base, it will have a different way of doing things. If it is an acid, the chemical H3O+ ions will donate protons to the indicator, causing the indicator to change color towards red. The base follows a similar way, the indicator gets the protons from the water molecules creating OH- ions. The H3O+ ions then donate protons to the OH- ions making the indicator turn the color towards purple. So if the liquid changes color towards red it is an acid while if it changes towards purple it is a base.

The ions present in the acid solutions are H+ which are hydrogen ions. The higher levels of hydrogen ions the more acidic it is. But the ions present in the base solutions are OH- which are hydroxide ions, the higher levels of hydroxide ions the more bases it has.

But what happens if you mix both the acidic solutions and the base solutions together? If you did mix those two together they would react and create a neutralization reaction that also forms a salt. According to Brønsted–Lowry terms, an acid can donate a proton H+ and a base is a substance that can accept a proton. Using two of the universal indicators is fine as they both do the same thing, so none of them is better.

Conclusion: 

Our experiment worked as we were able to tell which one of them was an acid and a base. If I were to do this again, I would change how long we boiled it for as we were behind as someone broke the beaker by accident which set us back a bit.

Aim:

We are trying to find out if the color of the cabbage water would change.

Equipment:

• Beaker
• Water
• Universal indicator
• Test Tubes

Method:

1. Get your cabbage and put it in the beaker.
2. Add some water into the beaker and put it on the heat until it boils for about a while.
3. Once it turns into the color purple, pour the liquid into two test tubes.
4. Once you’ve done that you need to add the universal indicator with hydrochloric acid into one tub and to the other one you need to add sodium hydroxide.
5. Watch and observe.

Hey everyone,

Over the past three weeks in wood tech we made a wooden project, called the knot. It took Alyxis and I over 4 periods to finish. Down below has a little picture of the tools Alyxis and I used during this project. As you can see we used a hand saw, a pair of glasses (we only used one so it would be quicker) and a file with sand paper on it.

I found making this project a really good thing to start with because Mr Down taught me how to use the hand saw properly and the file properly. I definitely feel more confident with doing my work after learning more about the tools and what they do. We definitely struggled with making it very even and symmetrical, Eventually we had to use the file, which was definitely a life saver and helped the pieces slide right on through.

In conclusion, I think Alyxis and I had a good time learning and bonding while doing this project. Underneath has a photo of the finished project and the pieces that make the knot, a knot.

1. Aim: why did we try to make a Universal Indicator?

1. Equipment: beaker test tubes pipets hot plates tea bags base and acid

1. Method: we put the tea bags into the beaker and then we put hot water into the beaker, put it on the hot plate then turned the hot plate on, and waited for it to boil. Then we got a pipet and put some of the tea water into a test tube and put some base and acid into it to see what it would do. 

1. Results:

1. Discussion: starting discussion questions (you can include more detail)
   • My indicator turned out to be dark orange and light orange
   • They changed color because of the hydrogen ions when we put acid into it, it went light orange and when we put base into it, it went dark orange.
   • Some were better than others since if I had a thing that I wanted to know if it was acidic or basic I would try it with cabbage 

1. Conclusion: starting conclusion questions (you can include more detail)
   • All of the experiments worked? 
   • I could improve it by doing more work and helping out.
   • add all of the other results to the table.

Kamusta bloggers! Today my topic for my blog post is to share with you all what we’ve been doing in Social Studies this week. Our topic for Social Studies this week is researching about a successful, and famous Maori individual from the past. This task also includes three different difficulties which are: Ace, Pro, and Legend (Ace if the easiest, Pro comes second as the easiest and Legend is the hardest), I choose to work on Legend to give some challenges.

Here is the slideshow where it shows my work!

1. Discussion: starting discussion questions (you can include more detail)
   • What colour did each indicator change in an acid vs. a base? My group did the beetroot it started off by being a deep red but once we added the base it was still red just a lighter red then once we added the base it turned an orange colour.

• • • Were some indicators better than others – if so, why do you think this is? Yes because some of them changed better coulers than others and if it changes color by a lot of them it means it worked. the cabbage showed that I could find out more information about the pH level because the colour changed better with gives be more information also about the cabbage indicator.

—Photo of the cabbage testing with both the base and when the acid mixed together. 

1. Conclusion: starting conclusion questions (you can include more detail)
   • did all your experiments work – if they didn’t, why? yes they did they worked because it changed colour when the acid and base were added.
   • What could you do to improve next time? Maybe try adding more acid to the beetroot and more base as well.boil it longer and experiment with more indicator 

Hola,

Today I will be explaining my clown and she wears/uses as props.

My clowns name is Lilac, she has a broken leg and has to use crutches. She is an assistant to a safety inspector, who believes she shouldn’t be there. This is because of the poor quality of the crutches. She refuses, and stays at work no matter what.

The scenario she is in:

Lilac and Harper – the safety inspectors – are inspecting a runway. Sophiah and Bubble are models who will walk the runway after the inspection. Penny is in charge of the runway and is very bossy. (We are still figuring out what we are doing…)
