Density Tower - Magic with Science at Steve Spangler Science Start your column by pouring the honey into the cylinder. Now, you will pour each liquid SLOWLY into the container, one at a time. It is very important to pour the liquids slowly and into the center of the cylinder. Make sure that the liquids do not touch the sides of the cylinder while you are pouring. It’s okay if the liquids mix a little as you are pouring. The layers will always even themselves out because of the varying densities. The same amount of two different liquids will have different weights because they have different masses. To test this, you might want to set up a scale and measure each of the liquids that you poured into your column. Density is basically how much "stuff" is smashed into a particular area... or a comparison between an object's mass and volume. The same goes for the small objects that you dropped into your density column. In the materials, we had you grab a bunch of miscellaneous tiny objects. Why do you think these two phenomena happen?

PlantingScience.org :: fostering student research through scientific inquiry and online mentorship Ten Websites for Science Teachers We all know that the web is full of excellent web resources for science teachers and students. However, unless you live on the web, finding the best websites can become quite a challenge. This isn't a "Top Ten" list -- instead, it is a list of websites that I either use on a regular basis or just find interesting. From teaching resources for the nature of science and authentic field journals to wacky videos about numbers, I am sure that you will find something in the following list the works for you! Please share your favorite science web resources in the comment section! 1) Understanding Science UC Berkeley's Understanding Science website is a "must use" for all science teachers. 2) Field Research Journals The Field Book Project from the National Museum of Natural History and the Smithsonian Institution Archives intends to create a "one stop" archive for field research journals and other documentation. 3) Evolution 4) PhET Simulations 5) Earth Exploration 6) EdHead Interactives video
