Kia Ora everyone!
Hope you are all staying safe at home! So as you may know we are still in quarantine and have online school. On Fridays my class would usually be going to tech (Technology) today so it was kind of like our own tech at home! We were assigned to watch a cool video about physical and chemical changes! In the video it showed examples of physical and chemical changes and underneath the video there were paragraphs that summarized the meaning of physical and chemical changes.
Chemical change means: Chemical change is when a new kind of substance is made e.g if you mix a gummy bear with hydroxide together it makes a gas which is a kind of substance!
Physical change means: A physical change is when there is no new substance made e.g if you put mentos into coke it will start to fizz and carbon dioxide will come out of it. This is still a physical change because carbon dioxide is one of the things that are used to make coke!
So after taking in all the new information that i had learned it was time to move onto doing an activity! There were 4 different science experiments that we could choose from and we could either do all or just one. I chose to do one activity. By the title you can tell what experiment i chose to do, but if not I decided on making a Chocolate Mug Cake!
While i was making it I was kind of worrying about it overflowing but when it came out it was actually small! I actually had made one in the morning but then just ate it and forgot to take a picture of it. oops. So i made another one remembering to take a picture before eating it. After making another one I didn´t like it as much as the first time and ended up not finishing it but it was still pretty good :). After cleaning up everything I got it out of the microwave when it had finished.
It looked kind of weird the second time i made it but it was all good!
After taking it out and making sure to take a picture of it i topped it with ice cream and sprinkles and some chocolate. Yes i did eat 2 but the first time it had nothing on it and I was sharing it with my sister and mom!
For the experiments the reason we had to try at least one out was because it was to see if we thought there was a physical or chemical change in it. For me I thought that this was physical change because all that happened was the appearance of it changed. So It was only a physical change that happened.
I didnt really have any troubles with doing this experiment and it was actually really fun and easy to complete!
Here is the link to the way to make the
Chocolate Mug Cake if you are interested in making a quick and easy dessert!
Like i´ve said before hope everyone is staying safe and remember to stay home and wash your hands!
