Greetings Scientists Everywhere!
We've been looking at signs of Fall in the garden and one of the biggest signs is the amount of sunlight.
Activity: What signs of Fall have you found?
------
In this video, the person explaining about seasons speaks really fast, but, does a great job explaining WHY we have seasons.
Watch it a couple of times if you can't understand what she's saying...
Earth is in SPACE, spinning and orbiting around and around!
* We have seasons on our planet because Earth is tilted.
(Leaning at an angle)
The tilt angles us towards the sun and away from the sun at different times of the year and that's why we have seasons!
* And that's why we notice the light changing in our garden and we can only grow certain plants at certain times of the year.
Activity: To observe our planet spinning through space, try tracing your shadow.
- If you have CHALK, have a buddy trace the outline of your shadow:
*Note the time you traced it!
* If you don't have chalk or can't go outside, you can use a piece of paper and sit near a window and do the same thing with a marker:
- Now, stand in the same spot on your shadow outline - what do you notice? Is your shadow in the same spot?
*WOW COOL! Your shadow shifted a little bit because our Earth is spinning through space.
* That's why we have night time and day time!
* The position of our Earth changes throughout the year - depending on where we are in relation to the sun... that's why we notice different changes in seasons.
What are some of your favorite Fall activities?
Remember the squirrels from last week?
