The Biggest Ever Living Spider’s Trip Around The World Wide Web

 

The biggest ever spider decided to take a trip … he set off from his home in the Amazon jungle and across the Pacific Ocean did flip. The biggest ever spider had legs that really were quite long – so he needed an enormous web which could hold his weight – that wouldn’t break and would be incredibly strong. The world wide web was bigger than a trampoline – it had to be in order to hold the biggest spider that had ever been seen. Off he set, bouncing at quite a height – onto Mount Kilamanjaro, where he stopped off for the night. Once the spider had rested, the elasticity of the web, he tested. He bounced up and down to check the elasticity and within minutes, ended up in Mexico city ! Once he’d made it around the globe, the biggest ever living spider, hoped that his next journey would be considerably wider. Perhaps, even big enough to take in the entire universe, so he could trip between the planets and the moons, of course. The world wide web might even cover the hole in the ozone layer, and cast a shadow across Earth, making it much greyer. I wonder if any of the world’s computer users know, how many wider spiders are making the internet go ?

Maths On The World Wide Web

Find ten maths sites that the biggest ever spider could use on the internet to help with the following maths problems.

1. If the biggest ever spider travelled at a speed of 25 km per day, and his journey lasted two years, how far did he travel ?

2. Imagine that the biggest ever spider fell through a hole made in the world wide web by Mount Everest. If he fell at a speed of 5 km / minute, how long did it take him to reach the bottom of Mount Everest ? (To answer this question, you need to find out from the www. how high Mount Everest is). Give your answer in minutes and seconds.

3. The biggest ever spider couldn’t swim, so he used the world wide web as a bridge to help him. If he was 0.05 of the width of a river that he crossed on his journey around the http://www., which was 3 km wide, how big was the spider ? What fraction and percentage is this ?

4. The biggest ever spider was so hairy that he had fifty times more bristles that all the coconuts in the Amazon jungle where he lived. If every coconut in the jungle had 150 bristles and there were 500 coconuts in the jungle, how many bristles did the biggest ever spider have ? Write an algebraic equation to show your working out.

5. How many bristles is that on each of the biggest ever spider’s bristly legs ?

6. If the biggest ever spider travelled 25% of the way across the equator, how far did he travel ? (To answer this question, you need to find out from the www. how long the Equator is).

Worldwide Writing Exercise

1. If you were an enormous spider and the world was covered in an enormous spider’s web, where would you travel to and why ?

7. What fishes might the biggest ever spider use the world wide web to catch ?

8. Name three different ethnic groups that the world biggest ever spider could possibly meet whilst travelling on a www.

9. Name three different continents that the world biggest ever spider could possibly cross whilst travelling on a www.

10. What might a spider eat on his trip around the globe on a world wide web ?

* Teacher’s note – this would be a good classroom ice – breaker for a lesson on the internet (whatever subject is being taught).

Answers :

1. 2 x 365 x 25 = 18, 250 km

2. From Amrita the Ant, Everest is 22 834 m high, therefore (22 834 / 1000 = 22.834) / 5 = 4.5668 min = 4 mins 30 secs.

3. a) 3000 / 100 x 5 = 150 m b) 5 % = 1 / 20 th

4. x = no. of spidery bristles, x = 150 x 500 = 75, 000

5. 75 , 000 / 6 = 12, 500
