The Scientists Return!

Today I brought in my microscope.

 Our spellings this week concern the prefixes “pre”and “micro” and suffixes “en” and “ment”. The two spellings on the list that I brought in were microbe and microscope. However, I had no microbes to view so they were substituted by something called paramencium. Paramencium lookes like green, orange or red grains of rice with small ovals inside.

Also, some people looked at a strand of my hair. If you looked at it with one light setting, it looked like a brown rope on a strip of black paper. But if you looked at it with the other light setting it looked like an actual strand of hair lit from the top.

You were able to change the amount of light in the first setting of light I mentioned. Do you think this makes a difference to what you see? Why?

Interesting Fact- Coils of Coils

I read an interesting article on DNA.

The DNA molecule is twisted round itself to form a coil, like a piece of string wrapped around a pencil. That coil is then twisted around itself to make a coiled coil.                                                                                                                                                       

If the coiled coil of DNA in just one human cell was unwound and stretched out in a straight line it would be over ten feet long.   If all the DNA in your body was unravelled, it could go to the sun and back  600 times!!!

Thinking like Scientists

Last week we were challenged to think like scientists in order to design a box that would hold 24 cylinders which were 2cm wide and 5cm tall.

 Working in teams of fours (and one pair) we measured the sides and faces, then we started building our box. The sides were made of green card stuck together with glue and sellotape. Lots of sellotape. Some were gigantic, others were tiny. A scientist called Susan came in to give us advice and help us make our boxes. Most of the boxes are finished now and they look great. A BIG thank you to Susan and Ms Fay who helped us design and construct our boxes.
