In this investigation, students will observe the changing patterns of clouds using a simple convex mirror mounted to a compass card. The focus of this investigation is on observing, classifying, and journaling cloud patterns.
This guide is designed to help you convert your students' work on these investigations into solid learning. In Unit 4, students will be introduced to clouds and weather through making observations (journaling) and using sensors to measure the environment. The Thinking About the Question section of this Investigation contains a teacher demonstration: Cloud in a Bottle. Students can download a Cloud Map, which serves as a reference for the cloud types discussed in the activity.
In addition to the questions in the activities and the test items supplied by the project, you may want to assess student progress in class where students can work in groups and use the equipment. After some practice, students should be able to determine a cloud direction using their mirror compass.
Hot water evaporates much more readily than cold water, so it evaporates easily into the air in the bottle, and the relative humidity rises sharply. The amount of time you spend on introductory discussions, data collection and analysis will determine your overall timeline. Graphing 101: Examples of graph types Posted by Dr. LINE GRAPH – This is the second most common, but frequently used incorrectly, so be careful here. PIE CHART – Pie charts are good for projects that have qualitative independent variables and have generated data that can be expressed as percentages of the total. SCATTER PLOT – If the purpose is to see if the variables are related (common in environmental projects), but there was not a clear choice for independent and dependent variables (for example wind speed and water temperature), then a scatter plot would be your best choice.
I am writing to make you know of the impressive encounter our daughter went through viewing your blog.
I would like to consider the ability of saying thanks to you for that professional guidance I have constantly enjoyed viewing your site. About my blog…The Science Fair has become a competitive sport and well-coached kids increase their odds of success.
Today we’re exploring thought experiments, quantum mechanics, a cat that is both dead and alive, and other things that make your brain hurt. But the Schrodinger’s cat thought experiment is really cool to think about, quite important, and is actually quite easy to understand. Alright, so let’s jump right into laying the foundations for understanding any theory in quantum mechanics!
But when you get down to super tiny things, such as atoms, all of those rules change and obey the laws expressed as quantum physics. The best way to think of this idea in quantum mechanics is to compare it to another thought experiment that we’re all familiar with.


Within the interpretation of quantum mechanics we’re exploring, the answer would be that a tree falling in a forest makes a number of different, crazy sounds. The concept of wavefunction collapse sounds pretty good, and explained a lot of the inconsistencies that quantum physicists were finding in their experiments. So, in order to explain the paradox that he saw, he came up with a thought experiment which we now call Schrodinger’s cat.
Then you drop a cat into the box (the cat can’t interfere with the previous setup) and seal it up. Now, according to the mathematics describing the wavefunction of the decaying particles, outcome would result in the cat being both alive and dead during the time the box is sealed. The Schrodinger’s cat thought experiment is great, because it connections the quantum world to the physical world and allows us to imagine viewing it with our own two eyes.
In terms of importance within quantum mechanics, the ideas expressed the Schrodinger’s cat thought experiment ranks pretty high. One of the most interesting things about quantum mechanics is the way in which theories and interpretations are conceived. But I digress, Schrodinger’s cat is a great starting point for exploring some of the ideas behind quantum mechanics.
I was working 50 hours a week as a retail slave (read: no computer!) when I created my first app, Reader Tracker. The students will also observe and describe the making of a cloud in a bottle during a teacher demonstration.
The actual process is investigated thoroughly in Unit 14: The Water Cycle, but a short explanation is included here.
In the case of a temperature sensor, a very small voltage is generated in the end of the sensor that is proportional to the temperature. For a safer, faster, more enjoyable user experience, please update your browser today or try a newer browser. You may select a bar graph when your independent variable is qualitative (categories) or quantitative (numbers).
You should only select a line graph if your independent variable is quantitative (numbers) and you hypothesized that the changes in the independent variable would result in changes in the dependent one.
She figured out lots of things, which include what it is like to possess a marvelous coaching mindset to have folks with no trouble thoroughly grasp selected advanced matters. I am pleased sure this post has helped me save many hours of browsing other similar posts just to find what I was looking for.
We’re looking forward to the commencement of my school research and the whole planning would never have been complete without coming over to your website. This blog is designed to help parents, teachers, and other mentors become better coaches for students wanting to successfully compete in a Science Fair. The Schrodinger’s cat thought experiment is designed to point out a paradox that exists in previous interpretations of quantum mechanics. A slight problem with the Schrodinger’s cat thought experiment is that the explanations of the experiment are still so damn hard to understand.


We’ll do it in such a way that would make a quantum physicist shudder, but works perfect for our specific examples today. For one, when exploring quantum mechanics, the state of every particle is described as a wavelength. You’ve also got a tiny piece of radioactive substance, a Geiger counter attached to a hammer, and a bottle of poison. Since it was first proposed by Schrodinger in 1935, a good number of people have built upon the idea with additions and thoughts of their own. It’s one of the most important ideas this century, and has become so famous that it would be a shame not to understand the reference. For example, line graphs are great for showing changes in the dependent variable over time or distance along a transect. If I could be of any assistance to others, I’d be glad to help through what I have discovered from here.
Throughout the website, you’ll see many sports-themed analogies because I want to connect science with something that might be more familiar – sports. I mean, just jump over to the Wikipedia entry for Schrodinger’s cat and try to get the gist of the experiment in a quick read through.
If you swing a bucket of water in circles fast enough, none of the water is going to spill out. Schrodinger did not buy into the idea that the behavior of particles was effected by the simple act of observation. And if you ever wake up to find yourself in a steel box with a Geiger counter and a hammer held just above a bottle of hydrocyanic acid, you’ll know the context of your know the context of your capture. Many thanks for offering those interesting, trustworthy, explanatory and in addition cool guidance on the topic to Emily. Both of these experiments rely on the human brain for interpretation, and the mind is not always completely reliable. By pointing out this flaw, Schrodinger opened the floodgates for a ton of new idea’s and interpretations.
Taking time to reflect while the investigations are fresh in students' minds has been shown to substantially increase learning.
When air is cooled, it can hold less water, so the water comes out of the air in the form of condensation onto the dust particles. In essence, Schrodinger’s cat was the spark that lit the fire of new and even better ideas in the world of quantum mechanics. When you combine these two phenomena, warm air rising at the equator has a lot of west-to-east velocity as it moves towards the poles.
It is going faster than the Earth's surface below, and this creates a high-altitude wind (jet stream) going from west to east.
