RIVER STUDY

RIVER STUDY VISIT TO CUERDEN VALLEY PARK

As part of our project about rivers, we visited Cuerden Valley Park and found out all about the features of rivers. We worked with the ranger and studied the River Lostock. We enjoyed working as geographers and measured the speed (velocity) of the river by timing how long it took rubber ducks to travel 10 metres.

Also, we compared the woodland habitat that we had studied at school with a river habitat. Mason found a clinging mayflower nymph – which looked quite scary!

WHAT IS THE DIFFERENCE BETWEEN A CENTIPEDE AND A MILLIPEDE?

WHAT IS THE DIFFERENCE BETWEEN A CENTIPEDE AND A MILLIPEDE?

By Jade Hebblethwaite.

Millipedes belong to class diploda and are more rigid arthropods recognised by the half cylindrical shape.

Centipedes have one pair of legs per body segments, while millipedes have two.

While most centipedes are known for their speed, millipedes move slowly and burrow in the ground.

Centipedes and millipedes also have different diets because centipedes are carnivores and millipedes only eat dead things.

Millipedes and centipedes prefer moist, protected outdoor habitats such as rotting logs, leaves,bark and the undersides of stones .

Surprisingly, a centipede has 100 legs and millipede has 40 to 400.

MINIBEAST HUNT

As part of our topic, “The Wonderful Wildlife of Westwood” we looked at our woodland habitat and searched for invertebrates. We wanted to find out where minibeasts play and and seek and had to look at the features of the microhabitats where we found the different creatures.

Back in class, we researched the different types of minibeasts and devised classification keys to sort and identify invertebrates.

Someone had a great question:

“What is the difference between a centipede and a millipede?”

Read some coming blogs to find out!
