Tuesday 5th May- Year 5 Home Learning: Science

Good morning Year 5!

I have a couple of experiments for you to try today which builds on your learning about mixtures. Hopefully, you have the bits you need at home already if you’d like to try the experiments- get permission from your parents first though! If you don’t have the ingredients you need, watch the video of the experiment (link below) and explain the science involved instead.

You will explore what happens when you mix particular liquids together. I expect you to investigate this properly, recording your results and observations of what you believe is happening. Take photos as things change and as you monitor the experiments during the day. Write a conclusion explaining what you noticed, and what you found out. Can you explain the science involved using accurate scientific vocabulary?

Experiment 1

Add drops of vinegar or orange juice to a small pool of milk and see what happens. You can use a small dish or deep plate for this, and add the drops of vinegar or orange juice one at a time. Observe carefully, and explain what you see happening. Can you explain why it’s happening?

Experiment 2

With a small bottle of cola, you can observe something else just as fascinating. But can you explain why?

We look forward to seeing your results and explanations! Send them, and your photos etc to the Year 5 email address. Have fun! y5upload@broadheath.coventry.sch.uk

The link to the website with the video. Spoiler Alert! If you want to carry out the experiment and see what happens, don’t go to the website before you do as it will tell you what happens!! https://www.stevespanglerscience.com/lab/experiments/invisible-soda/

  1. Experiment 1:when I added the vinegar to the milk I let it set for a few minutes and it started to go thicker and there where lumps of milk the glass when I spilt it in the sink.

    Experiment 2: I seen the coke separate from the milk and turn clear but a little bit yellow.

  2. In the video the when he put the milk in the cola it started to fizz a little bit.
    He filled it to the top and when it fizzed after a few moments it started changing into a lighter colour. It changed five or six times. It went from normal to light to light to light until it reached the bottom of the bottle then went dark and dark again.

  3. I have done the experiment with the milk and orange juice, my mum emailed pictures of it! Also, what happened was the milk had gone thick, and I could see bits of the milk in the plate separated from the orange juice which was interesting!

      • As you place in the vinegar it doesn’t mix . Although it was okay results I decided to put it through a couple more tests.
        First I left it for five minutes
        It didnt do anything so I was sad
        with results so I kept on this fun exploit. I mixed it down
        And the amazing thing happened it left small chemical reactions around it on the bowl
        It didnt want to give up now as I had already conducted 3 tests
        so I decided to try 1 more.
        I heated it in the microwave for 45 seconds. To my surprise the milk curdeled. That’s how it turned out !!!

  4. I have done experiment 1. The vinegar contains hydrogen and the milk contains protein. On the surface there were bubbles. It also creates a bumpy texture. There were small white lumps.

  5. Conclusion
    I tried experiment 1 , which was with the milk and vinegar . I Couldn’t tell what was happening . I saw it raise a bit but when I poured it down the sink it was really thick .

    • You have witnessed a chemical reaction between the milk and the vinegar. By mixing these two liquids together, you have changed the solution’s properties. Why did the milk go thick? What did the vinegar do to it? See if you can find out.

  6. I did both experiments. I think the most effective for experiment 1 was the vinegar and milk. However, I am still taking photos of experiment 2 and will leave it for maybe 3 hours.

    • It’s good to see you responding to blogs Pooja, can you send pictures of the experiment to the year 5 email address and can you also complete the other learning blogs.

  7. When you add juice to milk it became a purple yogurt-like substance because I used a summer fruits juice instead of orange juice because I didn’t have it.

    • That’s goof Nehemia, if you took any pictures can you send them to the year 5 email address. How long did it take for the substance to turn like yougurt? Can you use scientific vocabulary to explain this?

  8. When you add vinegar to milk, it curdles a yellowish water liquid settles on top. It’s because the acid in vinegar cause milk to curdle.

    • Why do you think milk and vinegar started to bubble Braydon? Did you took any pictures of your experiment? If you did please email it to us.

  9. When you add milk to the cola it slowly becomes transparent. This is because the reaction between the acid of the cola and the milk combined and slowly became transparent.

  10. When you add milk to the cola it slowly turns transparent. This is because of a chemical reaction between the cola’s phosphoric acid and milk

  11. When you add milk to the cola it slowly becomes transparent. This is because the reaction between the acid of the cola and the milk combined and slowly became transparent.

    • Harun, can you explain further why you think this becomes transparent? You mentioned about the acid in the cola, what about the milk? Use scientific language to explain this.

  12. When you add milk to the cola it slowly turns transparent. This is because of a chemical reaction between the cola’s phosphoric acid and milk

  13. I am glad you have tried this experiment Abdi.
    If you have any pictures from your experiment, please send them to us.
    What makes it fizz? What made the water go down?
