Some of this information I have already known but most of the information was new and I was really interested in and excited to learn about. Most of my questions got answered.I didn't have any problems today with anything and I don't have many more questions about my topic but I want to find new information about rainbows because from the information I already have, this topic is interesting and fun for me. Today I feel happy and excited that I chose this topic. I learned so many things I would have never known without doing this project. Next, I am going to look for more information in the other books I have and I didn't have any help from anyone today. (:
Wow! You did find a lot of information in that book!
ReplyDeleteReally great job on the whole blog so far. I liked this post the most though because I had no idea the rainbow had so many different meanings depending on the culture, with africans believing its a snake, some believing it's the bridge between heaven and earth. It's interesting and easy to understand, keep it up!
