Breathingearth - CO2, birth & death rates by country, simulated real-time 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?

A History of Climate Science Skeptical Science takes a different approach to Naomi Oreskes' Science paper who sorted her papers into "explicit endorsement of the consensus position", "rejection of the consensus position" and everything else (neutral). In this case, the backbone of our site is our list of climate myths. Whenever a climate link is added to our database, it is matched to any relevant climate myths. Therefore, each link is assigned "skeptic", "neutral" or "proAGW" whether it confirms or refutes the climate myth. This means a skeptic paper doesn't necessarily "reject the consensus position" that humans are causing global warming. There are a large number of neutral papers. So yes, categorisation can get a little complicated and I expect there will continue to be discussion on the issue of classification.

Understanding Evolution The bacteria that changed the world - May, 2017 The make-up of Earth's atmosphere, once the domain of Earth science textbooks, has become an increasingly "hot" news topic in recent decades, as we struggle to curb global warming by limiting the carbon dioxide that human activity produces. While the changes that humanity has wrought on the planet are dramatic, this isn’t the first time that one species has changed Earth’s atmosphere. Three billion years ago, there was no free oxygen in the atmosphere at all. Life was anaerobic, meaning that it did not need oxygen to live and grow. That all changed due to the evolution of Cyanobacteria, a group of single-celled, blue-green bacteria. Read the rest of the story here | See the Evo in the News archive
