A tricky question

Now here's a little quiz in which even the biology teachers can participate. We know that the sperm cell only delivers its nuclei to the egg cell at fertilisation. Why is it that the 2 cells (egg and sperm)do not simply fuse all of their cytoplasm together? It is known that none of the organelles of the sperm cell are delivered to the egg, only the nuclei.

So, why?

States of Matter

7K investigate states of matter.

The copper melts and falls into the beaker of water. What happens as the melted liquid coper hits the water?

Who is the owner of this shoe?

Over the holiday the science office moved around the corner to accomodate the new labs. All the 'junk' was packed in boxes and it is only until now that I have started to open some of them. In one I found this gem that I have to share with you. Last year Mr Lazaro asked his yr 10 chemistry class to do a homework on the uses of zinc. I remember seeing a quality flash animation and some interesting models, but not this. The cd was tucked away in the bottom of a box with no label so as I put it into the cd drive I was expecting to see some boring past papers! To my surprise I heard this on the cd (as a podcast). Even better, you can click here to see what was on the cd (if you are in school) or here if you are at home (47 MB mpeg). Sorry Paulo.

No bags please

The science corridor is a 'bag free zone'. Please leave your bags in your lockers.

If we need to evacuate the laboratories for any reason we need the floors clear of obstacles.

This is a school rule and you older students should know better.

Not another way to learn!!!!!!!!!!!!!

Listen and Learn... are you always able to remember a tune, song or lyrics, but struggle to recall facts in your exams? Many students who have a strong auditory memory find information sticks if they hear it rather than read it. At Patana the Science department will be putting together a list of mp3's that you can download and listen to whenever you like, on the school bus for example! Click here to go to a selection of mp3's that you can download now. Bookmark the page and visit it on a regular basis since new files will be added every week. Ever tried to play tennis on the moon? What would happen to Andy Roddick's 150 mph serve on the moon?Happy listening.

7R's Lab Rules

We always have to be safe in the Science Laboratories. 7R have come up with the following rules to help us stay safe, can you add to them?



1. Never run in labs.
2. Always wear lab coats when experimenting.
3. Leave bags outside the lab.
4. Tuck stools under the desks when experimenting.
5. Keep surfaces clear when experimenting.
6. Always light Bunsen burners on a safety flame.
