Why don’t spiders get caught in their own web?
Spiders only put glue droplets on some of their strands of silk,
and they tend to avoid these as they move around their web.
Spiders also only touch the web with the tips of their feet
(‘tarsi’), which have a non-stick coating. In addition, a special
claw on the end of each foot grips the web and pulls it against
springy hairs. When the claw is released, the springy hairs push
the web strand away, stopping it from sticking.

Calculators - Please remember that all Y9, Y10 and Y11 students are expected to bring a
scientific calculator to all science lessons. If they don’t, they will be issued with a half hour detention
for lack of equipment.
Y11 Revision - After half term we begin our revision program. Each student has been given a
program and this has also been assigned to them on Doddle, just in case they lose it. Additionally,
a parent version has been sent home via the text link service. You will need to ask your child which
science group they are in.
This revision program does not in any way replace the revision they should now be doing at home,
but it will give them a structure to follow which may help. We are also running revision intervention
after school every Thursday. These sessions will focus on the work covered that week.
23equations.com - This is a great app,
available for free in the App store and on Google
play. It gives tutorials and revision quizzes for all
the equations used in the exam - a great way to
revise.
