Experiment Idea - Water Weight II

I was watching a show tonight where a person was standing on ice that started to crack. They were told to lay down to spread out their weight more evenly and to start moving back to shore this way.

That got me thinking about the water experiment I posted the other day and I thought you could add a different question into the mix.

Does the shape of a container affect the weight of the liquid in it? So if I pour water into a cup and weigh it would it weigh the same as if I poured that same amount of liquid in a cookie sheet?

It would be fun to see children discuss it and then test it (recording results in their notebook). All you would need is three different size containers one that would spread out the water in a normal way, one that would condensed the water into a tight space, and then one that spread it out. You would also need a scale that could zero out the container weight prior to adding the water.

This is a simple, relatively inexpensive (I hope) experiment that could be done as part of any inquiry unit where you are introducing the scientific method to students.

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
