Water Rockets!





Today was our last lab! We had a LOT of fun. We used three different types of chemical reactions (synthesis, single replacement and decomposition with a catalyst) to COMBUST HYDROGEN. Guess what you get when you COMBUST HYDROGEN, WATER! We filled pipet bulb "rockets" with a mixture of hydrogen and oxygen gasses. Then we provided a little "spark" (to break up the hydrogen molecule and oxygen molecule into atoms and get them to react with each other) with a TESLA COIL! The reaction of hydrogen and oxygen gasses is exothermic and "shoots" the pipet rocket across the room! So much chemistry! So little time!
Be sure to check back for more pics! Josh K took some with his camera and when he gives them to me, I will add them!
Be sure to study for our last test, tomorrow on chemical reactions.

Today we reviewed the worksheets on the Periodic Table that you did last Thursday while I was away with Science Olympiad. Those who were present today should have all of the correct answers... if you missed class, check with them. QUIZ ON PT THIS THURSDAY!

April 9, 2008

Today we started looking at Acids and Bases. We need to know what acids and bases are, and how they could have an impact on the environment. We will need to look at the pH of the Riverwood water to determine if it was a factor in the fishkill.
We watched an video on Acids and Bases. Click here to get to the video. Click here to get to the worksheet that we filled out with the video.
We also worked on an interactive assignment at discoveryeducation.com We will continue this tomorrow.
