The Carbon Dioxide Experiment

Reported by David, Betsy, and Eve

Our experiment in science was to prove that fish exhale carbon dioxide.

We did this by placing a goldfish in a cup of water, then we added BTB which indicates carbon dioxide.

BTB starts as a shade of blue. When BTB interacts with carbon dioxide, it turns to a shade of yellow, depending on how much BTB was put in the water.

After about an hour, we looked at the cup with BTB, water, and the goldfish. Believe it or not, our experiment worked! The water was now a bright yellow!

December 2008

Students learned about the Create a Graph site in science from Mrs. Ade, and Jacob decided to try it out. Bravo, Jacob!

If you want to make a graph, plan your graph – think about the kind of data you want to show and the best way to show your data. Next go to the Create a Graph site and create a graph that fits your data collection. Mail your graph to me at school and we’ll work together to place the graph on your Class Blogmeister blog. Give it a go!

Here are the top 10 ways to be an expert at science –

• Ask questions to clarify your understanding
• Try things in different ways
• Never give up
• Get deeply involved don’t be lazy
• Be daring to investigate
• Don’t get frustrated if the experiment doesn’t work
• Think outside the box
• Try things that might not work
• Be safe
• Have fun but don’t go to overboard
