    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

    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

    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.

    7. Who do you think could have written it? Why? I think someone who would be interested in Volta’s life and experiments.

    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.

    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.

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

    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.

    Can we trust the information? Why?

    We can trust the information because the school provided it for us and the story was based on the name volt which is known today in electricity.

    Who do you think could have written it? Why?

    We think that someone who believes in the study of electricity and thought that it would be interesting for people to learn about the topic.

    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?
    Yes they changed other peoples ideas when the created the battery.

    4 What could have happened if Volta had agreed with Galvani?
    It probably wouldn’t work.

    5 Do you think this cartoon is reliable?
    Yes the information is reliable but probably not the pictures since it was a long time ago.

    6 Can we trust the information? Why?
    I think we can trust the facts

    Why did the scientists disagree?
    Because volta said that galvani’s idea of animal electricity was incorrect

    What was the first thing Volta did when he disagreed with Galvani? Why?
    He went and put a coin and foil in his tounge with a thin Price of metal in between them

    Did either of them change their ideas? Did they change other people’s ideas?
    No they didn’t becasue Galvani still said he was right

    What could have happened if Volta had agreed with Galvani?
    We would never have understood or relied the power of electricity

    Do you think this cartoon is reliable?
    Yes. Because the information has detai.lother websites suggest the same thing

    Can we trust the information? Why?
    we think so. Becasue other websites suggest the same thing about volts life

    Who do you think could have written it? Why?
    Someone like a close friend of family member, or someone who is interested in researching about him

    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.

    1 Why did the scientists disagree?
    Because Volta suggested Galvani’s work was incorrect

    Galvani? Why?
    He proving that Galvani is incorrect

    3 Did either of them change their ideas? Did they change other people’s ideas?
    No, don’t think so

    4 What could have happened if Volta had agreed with Galvani?
    It would be less chaotic and we wouldn’t have batteries

    5 Do you think this cartoon is reliable?
    Yes because it’s a biography about Volta

    6 Can we trust the information? Why?
    Yes because it’s the logo on the bottom left looks like a educational company

    7 Who do you think could have written it? Why?
    The department of education, because it looks like a book that you photocopy worksheets out of
