  2. Good Job Joy :) i really like you blog post and how you put a lot of hard work into it. but to make it pop more maybe you should add a different color.

  3. Good job Joy! I liked how you made your pictures look long so more of the text would fit in a an it would make it look clear when you read it. I also liked how you made your own pictures and a cool video! Maybe next time you should add some colours into your text? You know, just to make it look more interesting. Also, maybe you could how how you found out your answers in 10 and 4 a), b), and c) just to get a better understanding. For example, you could write how you do it step by step! Hope this helps and overall good job! Keep it up Joy! (=
