In my class you will have an opportunity to view bacterica cell under a microscope. The cells are frm a yogurt smear on a slide that Cory did. Right beside this slidw was a blood cell slide. How did the cells differ in size, shape, color, and function?
The planet’s present day greenhouse scourge, carbon dioxide, may have played a vital role in helping ancient Earth to escape from complete glaciation, say scientists in a paper published online today.
In their review for Nature Geoscience, UK scientists claim that the Earth never froze over completely during the Cryogenian Period, about 840 to 635 million [...]
Many studies of evolution focus on the benefits to the individual of competing successfully – those who survive produce the most offspring, in Darwin’s classic ’survival of the fittest’. But how does this translate to the evolution of species?
A new article considers an aspect of the natural world that, like survival of the fittest individual, [...]
Hello Students,
I am very sorry that last weeks final blogs didn’t show up. I tried everything to get the blogs to show up, but technology is not my friend at this moment. Anyway, we will begin with a fresh start this week.
Lets talk science fair—To ease your mind and emotions, I will check your draft [...]
The organs in the body have functions and if they don’t do what they are designed to do, then the body will not operate to full capacity. If the liver does not make enzymes, digestion is compromised and the body won’t make nice healthy stool. Relate this idea to organelles in the cell. Select an [...]
This blog is dedicated to Aaron Shine. I sure do miss you son. I can’t wait for your return to science; class just isn’t the same without you. You are so brilliant and your brain seems to absorb all that is there to soak up. I want you to know that you are very much [...]
Your family travels to a region that is extremely cold, a place where there seems to be no life form. Then they explore a very hot region and ran across a hot springs. What type of organisms do you expect would be at these places? You could possible find these organisms for years to come [...]
You should be home free at this point for the science fair project. Don’t forget to log and take pictures as you perform your personal experiments. What questions do you have? Don’t hold back, I will answer them in
Have you ever smelled body odor? What causes underarms to smell like death, especially after PE? What could possible happen if a person didn’t take showers or baths? Could it cause a major
Scientists of the Commission-financed project FULLSPECTRUM have developed photovoltaic (PV) multi-junction (MJ) solar cells which are able to convert 39.7% of the energy of sun light into electricity. This is the highest percentage ever reached in Europe, according to researchers after their final workshop today in El Escorial, Spain.
The main barrier to large-scale deployment of [...]
