Science discovery: How does bread rise?
Yeast makes bread rise. Yeast is a singled cell fungus. Without yeast in your ingredient to make bread, bread would and hard and flat. But how does yeast make the bread rise? Yeast cells like to feed on sugars. While yeast cells are eating the sugars, carbon dioxide and alcohol are released into the bread, which cause the dough to rise because of the moving atoms in the carbon dioxide and alcohol.
Science Discovery: What is a wind chill?
Have you ever heard the temperature is going to be 20degrees but the windchill is going to be 10degrees. Maybe not in those temperatures but similar? The windchill is the effect that wind has of making air feel colder than it actually is. Schools will cancel or delay if the windchill is bad enough, because wind can make the temperature feel way worse than it is. Also you could be out waiting for the bus and the wind could be blowing in your face, that is an awful feeling and hard to avoid. But if there is no wind, there is no windchill. The windchill is almost all the time colder than the actual temperature.
