Four Science Experiments on Tuesday

The Marine Biology textbook has several experiments, in each chapter.  This is the lab component of the curriculum and is required in the state of Florida.  Caitlin also had two experiments from her T4L Science lessons.  Since I can not share the actual copies from the book, I will try to find examples similar to what we did, so you can do them in your Science lessons.  The first video is a cloud video, and has nothing to do with experiments.  If your child is learning about Weather, it is a nice video.

I could not find a video for the Marine Biology experiments. So, I will give you a basics of what we did. Experiment 1: The Expansion of Solid Water. You need a bottle of water, a marker, and a freezer. Fill the water bottle about 3/4 of the way full. Mark the spot where the water is with the marker. Put the bottle in the freezer. Make your hypothesis of what you think will happen. Record your findings after the water has frozen.

Experiment 2: Removing the Salt from Salt Water. We have actually done this one before, but it is part of the requirements, so we did it again. You need a pot with one cup of water in it. Turn on the stove and heat the water, but do not boil. Add two tbsp of salt to the water and stir until dissolved. Pour the water into a pie plate or other container. Set outside, usually takes a week or more depending on temperature. Make your hypothesis of what will happen. Record your findings after. Try this in the Winter months also, to see the difference in the results.

I decided I will go back to keeping a daily log, rather than trying to keep up with it on the blog. I would rather keep the blog for fun, and interesting things to share. My Father in Law is coming, so we will not be back to lessons until next Tuesday.
