Jacques' Presentation

Jordan's Report on Spider's webs.

Funnel webs.

Some spiders live in burrow webs. The burrow is made of silk and is underground. Above the ground, the spider spins a funnel with long threads going into the burrow. Sometimes an insect gets caught in the web, the spider can feel it vibrating and eats it.

Lasso webs.

The Lasso web is also a type of spiders web which catches moths. This is how the spider makes the Lasso web: It makes a long thread with balls of glue at the bottom. This type of spider has hairs on its body so it can feel the moths moving. To catch the moth it spins the thread with glue at the bottom and the glue touches the moth so the moth gets caught and the spider pulls it in.

Dylan's Report on Spider's Webs.

Silk is what spiders make their webs with. Spider's silk is runny. The silk is squeezed through tubes from the spiders bottom half, at the end of the spider. After the silk is runny, it goes hard like steel. Silk is very thin. It takes a spider one minute to make one meter of silk. One million webs is what one tea spoon of silk can make. It takes a spider almost thirty meters of silk to make one web. Spiders eat their old web before making a new one.
When spiders are on their web they can't get stuck. Spiders webs are made with sticky and dry threads. The spider walks on the dry threads, so it does not step on the sticky threads. Only the spider knows where the dry threads are.
