Science Experiment Idea


It is no secret in my class that I like to drink diet coke from a bottle versus a can (mainly because I fear things falling into the open can). I also like my diet coke SUPER COLD. The other day I grabbed one from Walmart and thought to myself, "I wonder if there is a difference in temperature between soda in a can or in a bottle?" (and do they loose temperature at the same rate).

I thought I could tie this question in nicely with our unit on light we just started. We have been exploring properties of light (it contains energy) and what happens when it hits objects. Using information we have studied students would be introduced to the question and then they would have to make a hypothesis.

I thought it would be a nice easy classroom experiment. All you have to do is take a cold 12 oz bottle of diet coke and a cold 12 oz can of diet coke and then have students record the temperature of each every 5 minutes for about twenty minutes and discuss the results and what part light might have played in the experiment.

Be careful. You're also comparing 2 different materials (aluminum vs. plastic). So you have no real way of determining whether any difference is due to light or the thermal properties of the container. Perhaps using running comparisons using clear and opaque plastic instead?

My guess is that any difference is due to plastic vs. metal. I bet the plastic bottle stays colder longer.

I like the idea of comparing clear and opaque plastics. Funny I thought that the aluminum can would stay colder longer. Still haven't run the test in my classrom. We really need to get digital thermometers. My 9/10 year olds have such a hard time reading the thermometers we have!

I just wanted to say that I have really gotten some good ideas about notebooking and started to use these ideas in my special ed chemistry class. I have enjoyed it so much that we are starting this semester to use this in General Chemistry.

Thanks for the blog and keep it up!

Picture of the Day - Activity

I attended a training class and a science coach shared an activity that he does with his students to help them differentiate between observations, inferences, and predictions. He puts a picture on the interactive white board as a warm up (he gets the pictures from a variety of sources but uses National Geographic's Picture of the Day a lot). The picture above is from the National Geographic site. He has the students make five observations. Then he makes the students make five inferences. Finally he has the students make five predictions. He does this every day and it really drives home the difference between those three key inquiry vocabulary terms. I've done this activity with both my sixth and fourth grade science classes and the students really got into it and became proficient at telling me the difference between those terms.

Weathering, Erosion, and Deposition Activity

I saw this activity at a science conference years ago and haven't had a chance to use it in a classroom until this week (mainly because I didn't teach weathering, erosion, and deposition). It is a great way to reinforce the definition of the weathering, erosion, and deposition in a highly kinesthetic manner. Basically you break the students up into groups of three. One group is "Weathering" another group is "Erosion" and the third group is "Deposition". Add tape to the back because you are going to stick them to the forehead of the children in each group. The "weathering" students get a sheet of paper that is their "rock" they will be breaking down. At the start of the activity the "weathering" students will start ripping tiny pieces of their "rock" and handing it to the "erosion" students. The "erosion" students will be running their tiny piece of "rock...

Bill Nye Songs with Lyrics

At the end of the Bill Nye videos he always has a fun song that goes with the episode. You can find many of the songs as stand alone videos on YouTube. This came in handy because today I am teaching a lesson on layers of the atmosphere and found a song from his Atmosphere video on YouTube titled "Fresh Aire." I really wanted to remix it and put the lyrics on the video (so the kids could sing along and see how the lyrics matched the lesson). The first thing I did was found a site that has all the Bill Nye lyrics posted used my YouTube downloader ( see instructions here ) and downloaded the song. I then imported the video into Movie Maker Live and used the caption feature to put the lyrics on the different frames (cutting and pasting from the lyrics site into Movie Maker Live). I saved the video and reposted to YouTube so other teachers could use the video with lyrics (the finished video is posted above). The process was pretty easy and I am thinking about doing it for more ...
