  1. A.1
    Because electricity wasent running through the frog
    A.2
    He started to invent the first electric
    A.3
    Volta changed Luigi’s idea and Volta made the 1st battery so he changed everyone’s idea
    A.4
    We would of had frog electricity or on electricity at all
    A.5
    Yes because there is how Volta made the first battery
    A.6
    Yes because it says all the important information like when they were born ect.
    A.7
    the people around him because they were amazed of what he did

    • Q1.
      Because they both thought that their ideas were right.
      Later in the future you can see Volta was correct.

      Q2.
      He decided to find what was right and what was wrong because he found out why the frog leg moved.

      Q3.
      Yes because Volta showed all of the people at the French Academy of Science his findings in electricity.

      Q4.
      Yes because everyone would believe that animal electricity was reliable and would be used in the future.
      Imagine having a frog leg in the back of your TV remote.

      Q5.
      Yes/No because it in probably based on true facts but you also could do a bit more research to see if it is all right info.

      Q6.
      Yes you can find the main idea but you could do searches on it to find other facts that support this information.
      like I said before.

      Q7.
      I think someone how want to reach out and allow kids to understand this information in stead of searching through long boring websites.
      Primary school teacher or some kind of history review writer ? I’m sorry i’m not sure.

  2. 1 Why did the scientists disagree?
    Because they had different ideas that they wanted to be correct

    2 What was the first thing Volta did when he disagreed with Galvani? Why?
    The first thing he did was ago argue

    3 Did either of them change their ideas? Did they change other people’s ideas?
    Yes because Volta proved a point to all the peolpe

    4 What could have happened if Volta had agreed with Galvani?
    Maybe There ideas and opinions would change completely

    5 Do you think this cartoon is reliable?
    Not really because this happened a long time ago, it’s probably based on true facts
    6 Can we trust the information? Why
    Yes and no, you can get main idea on it but you would really need to research it more on many different websites

    7 Who do you think could have written it? Why?
    I think this was written for school children who reading practice so maybe a child educater or a primary school blogger
    ___________________________________

  3. 1. Why did the scientists disagree? I think both scientists were arguing because they both had different ideas they wanted to be true.

    2. What was the first thing Volta did when he disagreed with Galvani? Why? I think the first thing Volta did was argue with Galvani because he had a different opinion.

    3. Did either of them change their ideas? Did they change other people’s ideas? Galvani must have eventually agreed with Volta because he was proved wrong. I think Volta must have changed other people’s opinions when he completed his experiment.

    4. What could have happened if Volta had agreed with Galvani? People might have agreed with them or someone else would prove them wrong.

    5. Do you think this cartoon is reliable? I think the information it is based on is reliable but the pictures might not be because it was such a long time ago.

    6. Can we trust the information? Why? I think we can trust the basic facts but it might not be true word for word.

    Written by Zoe

  4. 1 the scientists disagreed because they had different ideas and thoughts.
    2 the first thing Volta did was suggested that galvani’s theory was wrong.
    3 Volta changed his idea and made other people change their ideas on how electricity works.
    4 we predict that they would’ve both experimented on Galvani’s idea and created a new type of electricity.
    5 we think the cartoon is reliable because they must have done a lot of research and there was a lot of information about Volta’s life.
    6 we trust the information because it has a lot of facts not opinions and it also has a lot of discripive words.
    7 we think some person who admired Volta made this biography about him.
    By Sam,Blake and Adalaide.

  5. Why did the scientists disagree?

    The scientists disagreed because they believed in different electricity circuits and they studied differently in electricity.

    What was the first thing Volta did when he disagreed with Galvani? Why?

    He tried to prove Galvani wrong by researching more about the topic and tried different experiments.

    Volta changed Galvani’s idea of the animal electricity and the people’s idea of electricity as they knew it.

    What could have happened if Volta had agreed with Galvani?

    If Volta agreed with Galvani he wouldn’t have discovered electric circuits which helps us with our every day lives.

    Do you think this cartoon is reliable?

    Yes because the school provided it and made us work on it. But they wouldn’t do that without knowing it is reliable.

    Someone like a close friend of family member, or someone who is interested in researching about him

    Emily and Tahlia

  8. 1. The two men disagreed because Alessandro Volta didn’t thought that was Galvani’s theory was incorrect.
    2. The Animal Electricity was incorrect and the frog legs twitch because the solution in the leg created a connection between the metal.
    3. Neither of them changed their idea, but Volta tried to prove him wrong by doing an experiment.
    4. If Volta had agreed with Galvani, we wouldn’t have the theory but eventually someone might have invented the theory again after Volta and Galvani died.
    5. My group thinks that the cartoon was reliable because we have prove due to modern day technology that we now have this theory. We can prove that it’s reliable by researching it on the internet.
    6. My group thinks that we can trust the source. Although the internet might not always be reliable, we can check on different websites, and if most of them include the same information, we will be able to prove that the source is trustworthy and reliable.
    7. Because this is a biography, my group thinks that a person like us (doing research on this particular topic) could’ve wrote this comic strip.

    A7. Someone could have written it for school kids like us and the person would be like a teacher or something.

  13. Alessandro Volta Questions

    Why did the scientists disagree?

    I think that the scientists disagreed because the both wanted the fame of being the first person to discovered electricity, or the fact that Volta told Luigi he thought that his work was wrong.

    What was the first thing Volta did when he disagreed with Luigi? Why?

    The first thing Volta did when he disagreed with Luigi was to go and study the topic more and found out why the leg twitched. He did this so he could prove Luigi wrong.

    Did either of them change there ideas? Did they change others ideas?

    Neither Luigi or Volta changed there own ideas but Volta changed Luigi’s idea to go on to later make the first battery.

    What could of happened if Volta agreed with Luigi?

    If Volta had of agreed with Luigi he would not have got the fame that he got for making the first battery. We would live lives without batteries to this day or someone els would have created batteries later down on the timeline.

    Do you think this cartoon is reliable?

    I do not think this cartoon is reliable for many reasons.

    Can we trust the information? Why?

    I do not think we can trust the information because of the time this happened the would not have been any recordings of what happened, and if there were any they probably would got lost to time.

    Who do you think would of written it? Why?

    I think that the only people who could have written this down would be Volta or Luigi if they had personal diaries.

  14. Alessandro Volta Questions

    Why did the scientists disagree?

    I think that the scientists disagreed because they both wanted the fame of being the first person to discover electricity, or the fact that Volta told Luigi he thought that his work was wrong.

    Q.2 What was the first thing Volta did when he disagreed with Galvani? Why?

    A.2 I thing the first thing Volta did was argue with Galvani about each other opinions.

    Q.3 Did either of them change their ideas? Did they change other people’s ideas?

    A.3 Galvani changed his opinion when Volta did the experiment and proved him wrong, also all the other people new he was right when he did the experiment.

    Q.4 What could have happened if Volta had agreed with Galvani?

    A.4 Someone else would prove them both wrong.

    Q.5 Do you think this cartoon is reliable?

    A.7 I think someone that was very interested by Volta and what he did.

  17. 1. Why did the scientists disagree?
    A: The two scientists disagreed as one though the idea was incorrect and the other thought it was correct

    2.What was the first thing Volta did when he disagreed with Galvani? Why?
    A: Volta demonstrated why Galvani’s theory was wrong and how it was wrong to proof Galvani that he was wrong.

    3.Did either of them change their ideas? Did they change other people’s ideas?
    A: Both of them didn’t change their ideas, but Volta’s idea was correct and he shared it with other people.

    4.What could have happened if Volta had agreed with Galvani?
    A: If Volta agreed with Galvani, we would have gotten the wrong idea and it would take a few more years to get the right idea.

    5.Do you think this cartoon is reliable?
    A: The cartoon is reliable in only some ways such as giving dates but it doesn’t give that much information.

    6.Can we trust the information? Why?
    A:I think we can trust the information because it is from a pretty well known company.

    7.Who do you think could have written it? Why?
    A: I think a person who likes reading comics would have written this to help other people who don’t like reading pages of information.

  18. 1. I think the scientists disagreed because they both had 2 different theory’s and Volta didn’t think that ‘animal electricity’ was possible.

    2. He showed Galvani what he thought, to show he was right. He did that because he wanted to prove he was right.

    3. The men did not change what they believed in through this project and I think Volta changed the minds of other people.

    4. If Volta agreed with Galvani we would never have the battery like we have today and we would be believing a myth.

    5. I do think this cartoon is reliable because firstly the school provided it and it has a good reason for how we got our battery.

    6. I think we can trust this information because like I said earlier the school provided it and it is reasonable.

    7. I think someone that is interested in electricity or a school teacher.

  19. Q1:
    The scientists disagreed because they both thought that their theories were correct.

    Q2:
    Volta ran his own experiment to find out more about the frog’s leg twitch so he could prove Galvini wrong.

    Q3:
    Neither Volta nor Galvini changed their ideas, but Volta proved his point correct to many and also tried to change Galvini’s idea.

    Q4:
    Volta would have no influence on society and the fame would belong to Galvini.

    Q5:
    I personally don’t think this comic is that reliable

    Q6:
    I don’t feel like this information is trustworthy because there wouldn’t have been a point of Galvini or Volta recording this information, since the story was so wide spread.

    Q7:
    I think an educational company designed to entice children wrote this comic because there is a logo and because this information is easy for children to understand.
