Summary
The article that I read about was on how bacteria proteins in the sky that can control precipitation patterns. The researcher named Bioengineer Tobias Weidner, leader of the surface protein group at the Max Planck Institute for Polymer Research in Mainz, Germany. He worked on a bacterium called Pseudomonas syringae it basically attacks plants by growing ice crystals how cool is that. But that bacteria at the same time it allows the plants to catch infections. Even with freezing temperatures. This article was posted on November 11, 2013 by Katharine Gammon called Ice, Ice, Bacteria (Not Too Cold)
Researcher Weidner did more tests on this bacteria protein like he took samples that are in Antarctica of the plant bacteria and created a film over water. Then put intense laser beams for a short of just 40 femtoseconds that's the amount of time it takes light to travel just one one-hundredth of a millimeter over the sample to examine the atomic motion of the protein and water molecules. In doing this he was going to get a better understanding on how it happens. Protein structures don.t commonly make a ice crystal around pants so that was a great learning for him and us.
So in conclusion finding this new earth creation that is formed by a bacteria protein to how it forms a crystals. I really

Introduction A greenhouse is a glass building in which plants are grown that need protection from cold weather. The natural level of greenhouse gases in our atmosphere, which keeps the planet about 30ᵒC warmer than it, would otherwise be- essential for life as we know it. Water vapour is the most important component of natural greenhouse effect. Greenhouse gasses are gas that contributes to the greenhouse effect by absorbing infrared radiation. Some of the greenhouse gasses are carbon dioxide, nitrous…

Science Inquiry Process Lab Report

In science class, we have been working on science inquiry process. Science inquiry has a lot of steps to make the whole process. We asked questions, made a hypothesis and we set up our experiment and gathered our data for 6 days. And ended the experiment with our conclusion. The purpose of the potato lab was to use the steps of science inquiry process to investigate a question. We did research to see what are other people's opinion for the best ways to have a potato to sprout at home, we used this…
