Preschool Science: Water absorption experiment

blooming in the desert

A few months ago, I bought a living social deal for 3 months of green kids crafts. As we got the boxes I put them up for days like today. Days where I’m not doing our actual school curriculum, but still want to do something fun and educational. I let Reanna choose the box and today she chose the water absorption experiment. This was great for her because she had to listen and follow my instructions exactly, and then wait patiently to see the results. 

Supplies Needed:

3 clear plastic cups, 2 paper towels, a stirring stick, and food coloring or color tabs (blue and yellow)

She filled 2 cups 3/4 full

Add coloring and mix

Roll up the paper towels lengthwise, fold and put one end in the blue and one end in the empty, and do the same with the yellow. We did it wrong at first :)

Science is the ability to distinguish knowing from believing (a test neither cladistics nor particle physics passes)

Menvall's Blog: Phylogenetics - change on different levels

When we discuss reality in general terms, we use classes. But classes is a tricky business, just like objects in specific terms is. However, while objects are tricky by being infinitely divisible, classes are on the contrary tricky by being infinitely contradictory, ie, paradoxically contradictory. The reason for both phenomena is the same, but the opposite to an infinite divisibility is an infinite contradiction.

This fact means that there is no way to make a single sense of reality, because we can’t make it in neither general nor specific sense, nor in the middle between them. Instead, our only possibility to make sense of reality is to accept that there are several just as sensible ways to describe reality. We have to accept that there are several different but equally true truths. The question is not which description of reality that is true, but which descriptions that…

Children conditioned by religion can’t tell fact from fiction

I went to catholic school.

A study published in the July issue of Cognitive Science determined that children who are not exposed to religious stories are better able to tell that characters in “fantastical stories” are fictional — whereas children raised in a religious environment even “approach unfamiliar, fantastical stories flexibly.”

In “Judgments About Fact and Fiction by Children From Religious and Nonreligious Backgrounds,” Kathleen Corriveau, Eva Chen, and Paul Harris demonstrate that children typically have a “sensitivity to the implausible or magical elements in a narrative,” and can determine whether the characters in the narrative are real or fictional by references to fantastical elements within the narrative, such as “invisible sails” or “a sword that protects you from danger every time.”

However, children raised in households in which religious narratives are frequently encountered do not treat those narratives with the same skepticism. The authors believed that these children would “think of them as akin…

Turn a science degree into a license to make a difference

Lyrebird Communications

When discussing my career choice recently I was reflecting with friends how a whole generation of young Australians wanted to be marine biologists. I think it had something to do with Alby Mangles, Harry Butler and the Leyland Bros snorkeling together on the Great Barrier Reef, or Totally Wild. I got as far as choosing between terrestrial ecology and marine ecology for my honours thesis, and I chose terrestrial ecology because I liked scuba diving too much to make it my job…[more on that later]

Neat Science Thursday – Persistent Science Myths

Gee-aI-eN-Gee

In spite of existing research, there are some seemingly scientific myths that just can’t seem to be dispelled. Here are a few myths and some excellent posts discussing their merit and why they may persist.

Why Using 100% Of Your Brain Would Make You 0% Smarter.
If you’ve ever been on the freeway and saw the guy next to you holding his coffee with one hand, texting with the other, and steering with his kneecap while doing 80, you might find it quite plausible that humans only use 10% of their brain. This is actually a scientific urban legend, though, and quite far from the truth. The man you see is engaging many parts of his brain – the driving uses the cerebellum, the texting uses his frontal lobe, reading his texts uses his visual cortex. He finally heard you honking after his kneecap steered into your lane. That’s…

Rabies Found In Wild Bat At Denver Zoo

CBS Denver

DENVER (CBS4)– A wild bat, not part of the Denver Zoo’s collection, has tested positive for rabies.

The bat was found at the zoo’s primate exhibit on Saturday. A zoo staff member safely captured the oddly-behaving bat and took it to the zoo’s veterinary hospital. The sick bat was humanely euthanized and sent to the Colorado Department of Public Health and Environment for rabies testing.

While some zoo visitors were in the same area as the bat, there were no reports of anyone making contact with it. To be safe, the zoo and the department are looking for visitors who were in close proximity to the bat.

“People who were at the zoo Aug. 2 should know about the rabid bat,” said state public health veterinarian Dr. Jennifer House. “Anyone who may have handled or touched a bat at the zoo, or learns their child had contact with a…
