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.

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.

   • 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.

Hello everyone, me and my class have been learning about Japanese culture. Currently, we are learning about the Edo Period. The work I have done for today is in this link here.

I find this type  of work interesting because it lets everyone learn about the past and what happened then.

This work wasn’t very hard, but very interesting.

Personally, I like Japanese culture, especially older Japan.

To summarise my work, I had to answer questions about items in the Edo Period, varying from weapons, to art pieces, then to facts about certain things in Japanese culture, and finally to current day Japanese things.

Thank you for your time, I’ll see you in my next blog. Bye!

today  we have been learning about the arts and history of Japan fun facts about japan Japan is an amazing island country full of unique customs, ultra-modern technology and quirky surprises and Vending machines everywhere You can find millions of vending machines across Japan

and they have lots of cool painting my favourite is the Hokusai  here Is a photo of it 

and any ways I hope u can see what I have done and I hope you liked the fun facts have a good day

Aim: To test the pH of a range of household chemicals.

Equipment: A variety of household chemicals, spotting title, red litmus paper, blue litmus paper,Universal indicator solution, safety glasses.

Method: Add a few drops of each chemical to a spot on your tile. If a substance is solid or powered you will need to mix it with a few drops of water before testing it.

Test the chemicals with litmus papers.

Test each chemical with a few drops of universal indicator.

1. Aim

The aim of this experiment was to test different household chemicals to find out whether they were acidic, neutral, or basic. We used Universal Indicator and litmus paper to see how the chemicals changed colour and determine their pH.

2. Equipment

• Universal Indicator
• Litmus paper
• Test tubes or containers
• Droppers
• Household chemicals
• Safety goggles
• Water
• Paper towels

3. Method

1. Put on safety goggles.
2. Label a container for each household chemical.
3. Add a small amount of each chemical to its labelled container.
4. Add a few drops of Universal Indicator to each chemical.
5. Observe the colour change and record the results.
6. Dip litmus paper into each chemical.
7. Record whether the litmus paper changed colour.
8. Compare the results from the Universal Indicator and litmus paper.
9. Use the colour changes to identify whether each chemical was acidic, neutral, or basic.

4. Results

5. Discussion

Why did different household chemicals change different colours?
Different household chemicals contain different types and amounts of ions. Acids have more hydrogen ions (H⁺), while bases have more hydroxide ions (OH⁻). These ions cause the Universal Indicator to change different colours depending on the pH of the chemical.

How did you know if the chemicals were acidic or basic using Universal Indicator?
I compared the colour of each chemical to the Universal Indicator pH scale. Red, orange and yellow showed that the chemical was acidic, green showed it was neutral, and blue or purple showed that it was basic.

How did you know using litmus paper?
Blue litmus paper turns red when it is placed in an acid, while red litmus paper turns blue when it is placed in a base. This allowed us to identify whether a chemical was acidic or basic.

Why might Universal Indicator be more useful than litmus paper?
Universal Indicator can be more useful because it gives an approximate pH, while litmus only tells us if something is acidic or basic. This means we can compare how acidic or basic different chemicals are.

6. Conclusion

Most of my experiments worked because the Universal Indicator and litmus paper changed colour as expected. If some results did not work, it could have been because the chemicals were contaminated or I used different amounts of indicator.

Next time, I could improve my experiment by using the same amount of each chemical and indicator each time. I could also repeat each test several times to make my results more reliable and check that I get similar results each time.
