I told 5C today, after we had watched a video about the brain (which I will also post here soon), that everything we see, hear or otherwise experience is generated by our brains and cannot always be trusted. The scientific method allows us to determine what evidence can be trusted by filtering out the biases that …

Polish Footprints…
A research paper presented in the Proceedings of the Royal Society has revealed tiny dinosaur footprints in the sedimentary rocks of central Poland. These rocks are 250 million years old, laid down in the Early–Middle Triassic period, which is 5 million years older than any previous dinosaur tracks. It is just a couple of million years …

Occam’s Razor…
Entia non sunt multiplicanda praeter necessitatem. So said William of Ockham (1285–1349) and I am sure we would all agree! This phrase became known as Occam’s Razor and it is a very important concept in science and scepticism. In simple terms, Occam’s Razor is the idea that when you are looking for an explanation for …

Science involves a process called peer review. When a scientist wants to publish his experiment report in a journal for others to read, it has to be submitted to a few other experts in the field who check that the basic science is sound. If they feel that a good job has been done with …

What Is Science? We Just Don’t Know…
Well actually, unlike with birds, we do know what science is. Science is a process that allows us to acquire knowledge. This is done by using observation and investigation to describe and explain the natural world. This allows us to produce useful models of reality. The word science is also used to refer to the …

Evolution…
The theory of evolution is often seen as the basis of modern biology, indeed it has been said that nothing in biology makes sense without evolution. Evidence from fossils, the geographical distribution of organisms and recent discoveries about genes all support the theory that organisms have changed over time. These changes are incredibly slow and …

Why Science Lessons Are Important…
Recently, someone sent me the link to the video below in which Dr Charlene Werner explains how homeopathy works. . Luckily, I did do some chemistry at school so I know what H2O is and I have heard of Einstein so I was able to follow her in depth analysis. I sometimes think it ought to …
