Term 4 Science- Night and Day

This term in Science we have been looking at Night and Day. We started the topic by brainstorming all of the difference between night and day. We have learnt about how shadows are formed and did an investigation to see how shadows change over the day. Here are some pictures of us recording our shadows out in the sun and also recording the shadows of a 'shadow stick'.

We have been learning about how the Earth rotates to make day and night and how the Earth orbits around the sound.
Did you know:
That the Earth rotates on it's axis once every 24 hours, which makes one day.
The Earth orbits around the sun once every 365 1/4 days, which makes one year.
We have leap years every 4 years to make up those 1/4 days.
Shadows change over the day. They are the longest in the early morning and late evening and are the shortest at midday.
Shadows start on the West side of an object in the morning and then move to the South at lunch, then the East by the end of the day.
WOW!
