Eluzions' Puzzles & Illusions
|
What is the minimum number of saw cuts you'd need to cut 27 cubelets from a large wooden cube, i.e. 3x3x3 like Rubik's Cube?
You may take any cut pieces and put them together any way you like for the next cut, which counts as one cut only.
Give a simple reason for your answer...
•
A cube of cheese is divided into 27 subcubes.
A mouse starts at one corner and eats each subcube, proceeding to the next that touched a face of the just-eaten subcube
(i.e. subcubes must touch on faces). Can it finish in the middle?

Explore Nature

As we move outdoors for the summer, thoughts turn to
gardens and nature. Looking for something unusual to
plant? How about some
olives or
sunflower? For a more natural environment to attact butterflies,
we suggest the
Wildflower Seed Mat.
If you prefer animals to plants, we have recently added some exciting kits.
The
Owl Pellet Kit reveals information about the food chain by examining the
undigested bits of an owl's dinner. They may contain
bones, seed husks, insect casings, fur and feathers. An illustrated worksheet
helps identify the bits.
For living creatures to care for, the
Triop
Volcano provides an easy summer activity. Triops hatch in 24 hours and grow
to a visible size in 2 or 3 days. They double in size each day until they
are fully grown, about 4cm. Triop Volcano gives an insight into the world of
these fascinating creatures
that have been on earth since before the time of the dinosaurs.
For life at a more basic level, the
Genetics and DNA Kit is a good introduction. Learn about the
biology of reproduction, the components of cells, and how chromosomes
are combined and copied. Assemble a model to see the elegant
double-stranded helical structure of DNA. Then crack the genetic
code and find out how the different parts, called nucleotides, fit
together to compose it. Read about how scientists use DNA sequencing
to reveal the order of nucleotides in DNA. . isolate the DNA from a
tomato . learn about inheritance and how traits are expressed . build
a DNA model . breed bacteria to experiment with genetic engineering Kit.

Physics Museum

The Physics Museum website now sports a nifty widget that displays photos from
Fotopedia. The photos are of course selected from
Physics-related pages, added by Alan.
Currently you need to download an application (Windows and Mac only) to upload your photos,
and it's unfortunately very fragile. After creating my first album I couldn't create another.
I understand they're working on fixing that, and also providing means to upload via the website.

When we think of hobbies, perhaps we normally think of stamp collecting, or photography, or gardening, or coin collecting..
But of course, one can probably make a 'hobby' of almost anything; perhaps the most fascinating for those of a curious turn of mind
would be based in science: studying the starry heavens, or examining bugs and crystals under a microscope, or hunting for fossils,
or collecting antique scientific instruments..
Here is a brief list of scientific hobbies suitable for children or adults.
Some may be more suitable for children than adults, or vice versa, due to cost or safety considerations
