Speed is distance divided by time. If no time passes, an object doesn’t move any distance. Doesw that mean that there is no such thing as instantaneous speed? If not, does the speed disappear every instant and reappear after a millisecond has passed? What happens to the momentum?
We did some math to find out how realistic space travel to the moon, planets, stars, and other galaxies would be.
We found that:

Check out Wikipedia’s explanation of a “Generational Starship” which might make very long trips possible.

We’ve sent people to the moon. Do you think we could send people to Mars? Should we? How about to Jupiter and Saturn, or one of their moons?
What are some of the problems with space travel to other stars? What are some possibilities for future space flight?
Check out these two websites:

What do they show about the size of the universe? How does the second one show that you are mostly empty space?
We can only see a small part of the electromagnetic spectrum – the visible light. Most of the spectrum, Radio waves, microwaves, infrared, ultraviolet, x-rays, and gamma rays we can’t see.
If you could see any part of the electromagnetic spectrum, what part would you like to be able to see? Why? What would things look like?
Here’s a picture of the electromagnetic spectrum!
Yesterday we started learning about how we can tell the age of the Earth. We discussed the difference between relative age and absolute age. We also learned the Law of Superposition (The Layer Cake Rule).
The word “relative” can be used to describe many things that are compared to each other. For example, when I sit next to Ian in a speeding car, I am moving relative to the road, but I am staying still relative to Ian.
What is relative age? What is absolute age? Give an example of each. What do you think relative speed would be? What is the Law of Superposition? What type of rocks does it apply to?
The Earth is known as “The Water Planet”. Despite this, there are many places where there is water nearby but nothing to drink. Before Thanksgiving, we imagined that all of Earth’s water fit in a 5 gallon bucket. We found out that about 2 cups would be ice and less than a cup would be groundwater. All the lakes and rivers would be a tablespoon!

You may remember the song, “Dirt Made My Lunch”.
Did it?
What is dirt? What is soil? What is the difference?
We went on a field trip to look at some examples of how the earth changes. Give examples of at least two of the following things that you saw:
