July 7th

Hi! It’s Fran and Ellie writing the blog for Irchester this week.

We wanted to show how our Questions Board guides what we do in our Lab_13. Last week we looked at the question “What is the difference between a microscope and a telescope when they both make things bigger?”

The committee contacted the Northants. Amateur Astronomy Society and were invited to take part in a Solar Watch at Newton Field Centre. Chloe’s granddad who built his own telescope came with us too. It was very cloudy and rainy all day but we were very lucky as the sun came out for about 20minutes in the evening.

Using a variety of different telescopes and solarscopes we saw some amazing things. We saw the sun through a filter lens, (which is a lens that only lets in 99.9% of light through so you don’t damage your eyes.) We saw solar flares, sunspots and looked at the difference between the outside and the centre of the sun – Chloe said it looked like it was bubbling. Joe even saw a plane fly past the sun when he was looking at it!

We learnt that we are in a very lucky time. The sun is approximately 400 times the assize of the moon. It is also approx 4000 ties the distance to our Earth away. This means that we are able to see total solar eclipses now but in years to come they won’t match up as exactly.

Following that amazing visit, Mr Freville the President of the N.A.A.S came in to talk to Year 3 about telescopes. He brought in an old fashioned telescope, that he had built himself, and a modern one. Plus, he brought in a pair of binoculars, field scope and a microscope. He showed us and Year 3 how the lenses and mirrors worked together.

                          

Even more importantly, we found out the answer to ‘What is the difference between a microscope and a telescope if they both make things bigger?’ and it is… The difference is that microscopes make things look bigger than they really are, and telescopes make things that are far away appear a bit closer!

Next for Year 3 will be making up their own Crazy Constellations using real star maps.

Bye for now!
