Owl pallet and the other stuffs 1

Lucy and me had fabulous time last Sunday in Cambridge science festival.
She thinks the most interesting activities are the antibody model and dissect of owl pallet.

Here is the antibody model she made.



Plastic plate resemble the cell membrane, which is the barriers on the outside of cells. They separate the insides of cells from the outside.

The blue pipe cleaner resemble the trans-membrane protein. They are molecules which go through cell membranes , so they can pass messages from the outside to the inside of cells.

The red pipe cleaner resemble the antibody. Antibodies are proteins which recognise and stick onto other molecules. Your body makes antibodies which help protect it against disease. Antibodies can be made and used as medicines.

How to do the model?

You need a plastic or paper plate, some different color pipe cleaners, some metal rings, a pair of magnetic jewelry clasps.

First poke some holes on the plate. Then use some pipe cleaner to thread through the holes.
Finally put the pair of magnetic clasp on the both side of one pipe cleaner, and twist the pipe cleaner to make a 8 shape.
