Memorandum

  • The garden snail
  • Octopus and mussel
  • Muscular foot
  • Two pairs of feelers and two eyes
  • The snail propels itself by means of wavelike movements of the muscular foot.
  • The mouth is T-shaped, placed at the bottom part of the head.

Assignments:

1. Plants that are close to the soil surface will probably grow luxuriantly. Animals that live on snails, like centipedes, birds and mice would probably look for alternative feeding areas.

2.

Earthworm Round, elongated body facilitates making holes in the ground, carrying plant litter into the ground and ingesting it with the soil Lives in damp soil to keep skin moist System of tubes to control the amount of water that is taken in or lost
Locust Can move around to look for food. Biting mouth parts for cutting up plant material Tubes branch inside the body to provide a moist surface for gas exchange External skeleton prevents loss of moisture. Obtains moisture from plant material
Spider Learners simply summarise information from text.
Crab
Snail

3. Research assignment: assess in terms of the framework supplied in the module.

Activity 12: to study the garden snail and to compare the adaption of a few invertebrates with regard to survival [lo 1.1, lo 1.2, lo 1.3, lo 2.3, lo 2.4]

The garden snail

The snail belongs to the group of molluscs or Mollusca . Can you still remember which other animals belong to this group?

The _____________________________ and ________________________________

It will not be difficult to find a garden snail. Look at its external build and try to answer the following questions:

The largest part of the body consists of a ______________________________ foot.

On the head are two ________________________________________________ and

Place the snail on a glass plate and when it begins to move, look through the glass from below and describe what you see (how it moves).

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
s.
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
Tarell
what is the actual application of fullerenes nowadays?
Damian
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.

so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
