Learning Objective: I will understand timezones and
how they work.
Last night in homework you learned a little bit about time zones and how they work. Now you are going to do a couple of activities to see how well you remember what you learned!
First, READ THIS:
The rotation of the planet means that we can't have just one time zone
for the whole world. If that were the case, then noon would be the
middle of the day in some places, the evening in other places, and the
middle of the night somewhere else. In some places, the Sun would go
down at 7 p.m., but that same hour thousands of miles to the east would
be the time the Sun was rising.
(If you are interested, you can read even more about timezones byCLICKING HERE)
Second, CLICK HEREto look at The World Clock and see different times in the world right now. It's pretty fascinating stuff! :)
Third, CLICK HERE to take a 10 question quiz about timezones. Good luck!!!
Here is your vocabulary for this week. Make sure and get to know these words. They will be very helpful to you on our assessment on Friday :) Good luck!!!
3.5 Vocabulary
Learning Objective: I will understand traversable networks.
Key Vocabulary-
network: a diagram consisting of arcs (branches) connecting points or nodes (junctions). A network may represent a real-world situation, such as a road system or electronic circuit. Sometimes the nodes are called vertices.
traverse the network: the process of tracing each path of a network without going back over any path a second time.
Look at the bus route below. This is an example of a network. Engineers and designers work together to form the best and most economic way for a bus to travel.
Definition of a Traversable Network (For original post by Passy's World of Mathematics, CLICK HERE)
A “Traversable Network” is one where we can find a route through the
network, along the edges, that uses all of the edges only once.
A network is said to be traversable when it is possible to start at a
“Vertex” (or “Node”), and trace out the whole network without having to
retrace over any of the connector “Edges”.
The following is a Traversable Network, because we can easily get
around the Network traveling along each Edge (or connector) only once.
Now watch the video about traversable networks:
Are these shapes traversable? Remember if you can traverse the network, you will go across each path without going back over any path a second time.
Here is our flipchart from class about networks:
Topic 9.5
This week we are starting our unit on Earth's Surface. There are a few things you need to know to get you started. Here are a FEW of the key vocabulary words that you are going to want to know for this unit.
Now watch this video about Weathering, Erosion, and Deposition:
Next, watch this video clip, before you know it, you will be a scientific super hero ;)
