Tales From The Farm – Help Name Rosie’s Lambs

Yesterday we heard the sad story of the lamb that did not survive. Rosie’s mum has been in touch to tell us how the other little lambs are doing.

As you can see from the pictures, they are all doing great. It was cold on the farm yesterday, as the family went about their duties, making sure the sheep and lambs were healthy and content.

Rosie’s dad has been ploughing the fields, and getting ready to sew oats and barley. Do you know what they look like?

Can you see the difference between the two photos?

There is always work to be done on the Farm, and it is not a 9am to 5pm job. It is a way of life.

Rosie and her family are going to find out whether the lambs are male of female and have asked Jump! readers to help name them. The lambs are named in alphabetical order, so this year their names should start with a “D”.

What do you think? What names do you like?

Leave a comment to suggest a name and Rosie will pick the names she likes best.

Science News – Solar Storms Due to Hit Earth

This weekend the Earth is due to be hit by a pair of solar storms that might affect radio and satellite communication. But how and why does this happen?

What Does Solar Mean?

Anything that is related to a sun is commonly described as being solar. Our sun is a typical medium-sized yellow star which is about 5 billion years old. Its surface temperature is about 5,500°C, but even that isn’t as hot as its superheated centre. Some parts of the sun’s surface are cooler, with a temperature of between 2,700–4,200°C, and these appear darker when viewed through specialised telescopes. These cooler patches are caused by fluctuations in the sun’s magnetism and are called sun spots.

Adventure in Uganda

On my second day in Uganda, we went white water rafting on the Nile, near a town called Jinja. The rapids are just down river from Lake Victoria, which is where the Nile starts.

The rapids are caused by the force of the water as it crashes over rocks and around islands in the river. There used to be more rapids there, and the famous Bujugali Falls. However, a couple of years ago a dam was built across the river, which has made part of it more like a lake and has increased the water levels, wiping out lots of the rapids, including Bujugali. However, below the dam, the rapids are still just as scary! The rapids are a favourite for rafters and kayakers all over the world.

Cellular Communications

When we talk about ‘cellular communcations’, we are not referring to use of a cell phone, because before mobiles or cell phones there was a time when this only meant cell to cell interaction within an organ or tissue. This important cellular behaviour drives diverse functions from contracting cells in your heart muscle to the cells in your nerves.

Do you use Facebook? While it is officially banned for under 13 years, a survey last year showed that almost half of Britain’s pre-teens have a Facebook account. Joanna Bradey tells us what she likes about Facebook.
