Hello, and my name is Caiden and today I will be showing/talking about the work I have done for Social Studies Japan today. The Edo Period was an important time in Japan’s history, lasting from 1603 to 1868. During this period, Japan was mostly peaceful and became more isolated from other countries. In this blog, I will explore Japan’s geography, its wars and empire, and the art and technology that developed during the Edo Period. I’ll also look at how these things helped shape Japan’s culture and way of life. Now I will be showing you the work I have done for this week.

Thats all the work I have done this week, cya in the next blog

4 September 2026

For this week (7),I have been researching Japan’s History. For example: I have learnt about Geography, War & Empire and Art & Technology.

I had done my work on paper for Geography, so I’ll tell you what I did:

I had named all regions of the world including Japan:

Hello, everyone my name is Bailey and today I will show you my work that I have done                                                                                                    this week.
Edo Japan

Warfare

Before the Edo period, Japan experienced more than a century of civil war. Powerful warriors and daimyo, or regional lords, fought for land and power. Oda Nobunaga, Toyotomi Hideyoshi and Tokugawa Ieyasu helped bring the fighting to an end. After

Hideyoshi died in 1598, Ieyasu became the most powerful leader. In 1600 he defeated his rivals at the Battle of Sekigahara. In 1603 the Emperor gave Ieyasu the title of Shogun. Ieyasu established his government in Edo, now called Tokyo. The Tokugawa family controlled Japan for around 250 years.

Thats all for today!

BYEEEE!

Hello everyone this week we have been learning about the Greek Olympics.

DISCUSSION

• Different household chemicals change into different colours with universal indicator because some were more acidic and some were more basic.
• An acidic chemical would turn red, orange, or yellow with indicator. Neutral would be green. Basic chemicals would turn teal, blue, or indigo.
• Universal indicator can be more useful than litmus paper, because it shows how acidic/basic it is. Litmus paper just tells you that its either acidic or basic.

CONCLUSION

• Our experiment did work because we followed the instructions
• We could’ve improved our experiment by trying even more chemicals

Aim

 The Aim was  to test common household liquids using red litmus paper, blue litmus paper, and universal indicator to determine whether each substance is an acid, a base, or neutral.

Equipment

• Red litmus paper strips

• Blue litmus paper strips

• Universal indicator solution (or paper strips)

• Spot plate /small testing cups

• Pipettes/droppers

• Safety glasses

• Tested chemicals: Vinegar, Spray and Wipe, Dish Soap, Floor Cleaner, Fabric Softener, Toilet Cleaner, and Dishwash Liquid

Method

1. Place a few drops of each liquid test chemical into separate wells on the spot plate.

2. Dip a piece of red litmus paper into each chemical sample and record any color changes.

3. Dip a piece of blue litmus paper into each chemical sample and record any color changes.

4. Add 1–2 drops of universal indicator to each chemical sample, mix gently, and record the final color.

5. Compare your results to a pH color chart to determine if each substance is an acid, base, or neutral.

Discussion

What colour did each indicator change in an acid vs. a base?

• In an Acid: Red litmus stayed red, blue litmus turned red, and universal indicator turned red (or orange/yellow).

• In a Base: Blue litmus stayed blue, red litmus turned blue, and universal indicator turned blue (or purple).

• In a Neutral solution: Red litmus stayed red, blue litmus stayed blue, and universal indicator turned green.

Were some indicators better than others — if so, why do you think this is?

Yes Universal Indicator was better than litmus paper. Litmus paper only tells you if a solution is an acid or a base (a binary answer). Universal Indicator consists of a mixture of dyes, so it displays a range of colors. This allows you to estimate how strong the acid or base is based on the specific color shift on the pH scale.

Conclusion

Review & Improvements

• Did all your experiments work? If they didn’t, why?

  • Most tests worked well, but some results had minor errors. For instance, Dish soap was classified as a base, but its universal indicator turned blue while its test row noted blue indicator results across the board. In contrast, Dishwash liquid turned green (neutral) with universal indicator, yet turned blue litmus paper red in the preliminary test row. These discrepancies can happen due to contamination on the testing tools or misinterpreting slight color shades.

• What could you do to improve next time?

  1. Use clean, unused pipettes for every sample to avoid cross-contamination.

  2. Use a digital pH meter to obtain exact numerical pH values alongside the visual color tests.

  3. Ensure the test liquids are completely clear or colorless so their original color doesn’t distort the color of the indicator.

Why did we do this experiment?

We did this experiment to test the pH scale of a range of household chemicals such as floor cleaner, oven cleaner, and toilet cleaner to decide whether it is a acid or a base. To do that, Mister Penrose put those chemicals into a tube to let us squeeze the pipette into. To do this we used litmus paper with a color of blue and red. I will tell you what we did with the paper shortly.

What did we use for this experiment?

We used pipettes, a spotting tile, litmus paper, and most importantly the household chemicals.

What did we do to complete this experiment?

First, we went to a station with one household chemical; floor cleaner. We used the pipette to gather some floor cleaner to drop it into one of the tiles in the spotting tiles. Next, we used to litmus paper to see what color it would turn into; if we used a red litmus paper, dipped it into the solution, and it turned blue, then that would mean it was a base. If the color stayed the same then it would be an acid. What makes an acid is when

Discussion: starting discussion questions (you can include more detail)
Why did different household chemicals change different colours? Use following words in your answer: acid, base, neutral
How did you know if these chemicals were acidic or basic?
Different chemicals changed different colours because they have different pH levels.
Acids turn blue litmus red and universal indicator orange, yellow or red.
Bases turn red litmus blue and universal indicator blue or purple.
Neutral chemicals do not change litmus and turn universal indicator green.
We knew what each chemical was by looking at the colour changes.

Conclusion: starting conclusion questions (you can include more detail)
did all your experiments work – if they didn’t, why?
What could you do to improve next time?

Most of the experiment worked. The contaminated 7 Up and fabric softener were acidic, Spray and Wipe was basic, and the floor cleaner was neutral. The dishwasher liquid was recorded as neutral.
Some results may not have been completely accurate because the equipment could have been contaminated or the colours were difficult to see. Next time, we could use clean equipment, fresh indicator paper and repeat each test.

hello bloggers today is what I did for science.

1. Aim: why did we do the experiment? We did the experiment because it was cool and it also was because we were testing how acid and base each households are and also how strong each of them.

1. Equipment: what did you use for your experiment? A testing tube, some chemical as inderviesall indicator. Litmus paper. And other things but i can’t rember 

1. Method: what steps did you complete to get your results for your experiment? Make sure your steps are numbered (like a recipe) we used 

Some household chemicals. 

1. In your spotting title add a few drops of each household chemical into its own well.
2. Each chemical with both red and blue litmus paper
3.  Recorded your observations in the tablefrom slide 166
4. Add a few drops of universal indicator to each well.
5.  Record observation in the table form slide 166 
6. For cleaning up we dispose of litmus paper in the bin and wash all chemicals down the sink with water.

   • Why did different household chemicals change different colours? Because it was a chemical rection
   • How did you know if these chemicals were acidic or basic? Because it said and we did research 
   • Why might Universal indicator be more useful than Litmus paper? It shows a full speterm of colors that corrspeond to specific numbers on hp scale

1. Conclusion: starting conclusion questions (you can include more detail)
   • did all your experiments work – if they didn’t, why?  Yes they work 
   • What could you do to improve your science next time?idk

1. Aim: why did we do the experiment? We did the experiment to discover if the substance is acid or base and defined by their behaviour and properties in water.

1. Equipment: what did you use for your experiment? The equipment we use for the experiment is blue and red litmus paper, test tube, universal indicator and some test subjects.

1. Method: what steps did you complete to get your results for your experiment? Make sure your steps are numbered (like a recipe). 

1.)Firstly you need some test subject like something you drink

2.) You need litmus paper, a universal indicator and test tubes.

3.)Put some test subject into test tube and put the universal indicator mix it and look what color it have (ROYGBIV) is the only color its 1-14 7 is natural below 7 is acid and upper 7 is base

4.) Lastly, get the color on the litmus paper and you can figure out if it’s an acid or base.

1. Aim: why did we do the experiment?

We did the experiment, finding different chemicals commonly found in households and using universal indicators to find how acidic the chemicals are and litmus paper to find out which chemical is base and acidic. 

1. Equipment: what did you use for your experiment?

Safety glasses, Spotting tile, Litmus paper, Universal indicator, Household chemicals

I wasn’t there. 

• What could you do to improve your science next time? Think about the reliability of your data. 

Because the universal indicator was already presenting the Ph of the chemicals the litmus paper didnt show up as much for some of the chemicals because the universal indicator was in the way, maybe next time we should use the litmus paper before adding an additional chemical.

Aim: We were learning what different type of equipment could tell us what substance was an acid, what was natural and what substance was an base, and how to use them.

Equipment: spotting tile, Universal indicator, pipette, red litmus paper, blue litmus paper, and Different substances; Dish Liquid, Fabric softer and Vinger, and safety glasses (MUST HAVE THEM)

Method: 

Step 1: PUT SAFETY GLASSES ON (OR YOU WONT BE ABLE TO TAKE PART), get  a spotting tile, and add a substance using a pipette.

Step 2: Put litmus paper in the substance, and if its an acid it will either stay red it the paper is red, or turn red if the paper is blue.

Step 3: put a few TINY drops of Universal indicator into the substance, BUT MAKE SURE YOU’VE TAKEN THE LITMUS PAPER OUT OF IT, and stir it with the Pipette

Step 4: log the Data into your Chromebook.

Discussion: 

Conclusion:

1. Aim: why did we do the experiment?

• The aim of this experiment was to understand what the difference is between base and acids, understand the use of litmus paper, and understand what a Universal Indicator is.

1. Equipment: what did you use for your experiment?

• For our experiment we used :
  • Pipette
  • Spotting tile

   • Why might Universal indicator (U.I) be more useful than Litmus paper? 

• Different household chemicals change into different colours when mixing with the universal indicator. This is because the reaction of the ions in the chemical and the indicator react together and it changes the colour of the liquid. If this liquid turns into a warm colour, this would mean it was acidic. Likewise, the opposite way. This also goes for the Litmus paper.
