Cause Effect Flash Flood Alert


♪ ♪ – [Paige]Watch out! – [Reed]Paige! What are you doing? – [Paige]Sorry, I was trying to put
together a machine to demonstrate cause and effect for a class. It’s a Rube Goldberg machine!
– [Reed]A Rube Goo-machine? – [Paige]Rube Goldberg?
It’s so cool. It’s a conflict contraption designed to
perform a simple task. Mine makes soup! Here’s how it’s
supposed to work, one thing occurs and causes something else to occur
and that goes on and on like a chain reaction! – [Reed]You’re the first person ever to
make rubber chicken soup! [laughter] – [Paige]Bon Appetit! [chicken sounds] – [Reed]I like the
chain reaction machine, it kind of reminds me of cause and effect text structure. I
just found an example of it in this book I got on killer floods. Check it
out. – [Narrator]Hold that thought! Will Paige’s vision of bowling balls
and chickens create a dream machine? Will torrential floods continue to
swamp Reed’s thoughts? Make sure you watch “Elements of
Destruction” and “Floods of Fury” before proceeding. Then, join the Knowledge Seekers as
they set off on a lesson in chain reaction cause and
effect text structure in this episode of Thinking Aloud! ♪ ♪ ♪ – [Paige]The hard part of this is
predicting exactly how the parts will work together.
– [Reed]Kind of like predicting a flood. Listen to this, “Saving Lives. Forecasters study the conditions that
lead up to a past flash flood or its fingerprint. These fingerprints such as rapid snow melt, torrential
spring rain or ice dam breakage provide valuable
information because forecasters use this past
information coupled with the latest radars and technology. They
are then able to make more accurate forecasts. When
weather conditions may result in flash floods, watches and warnings
alert the public. Due to these critical warnings, lives
are saved even if there are only minutes to
evacuate and move to higher ground. – [Narrator]We interrupt this video to
bring you this special news bulletin. It’s time to watch how Reed slowed down his
thinking to consider how cause and effect text structure and signal words
helped him make sense of the author’s message. – [Reed]”Saving Lives”…the title indicates the passage will describe how people
can be saved. The first two sentences discuss the
causes or conditions of a flash flood and now I see that forecasters
called these conditions “fingerprints.” When a word like
fingerprint has quotation marks around it or is
written in boldfaced type, it signals that it is an important
vocabulary word that I will want to remember. Now, the
author has been using a lot of signal words and there should
be some around here. There’s because, which the author
uses to describe a cause or why something occurs. The forecaster’s ability to use information
from the fingerprint, radar, and technology causes something to
happen. The signal word “then” tells me that I’m going
to find out the effect, which is that forecasters are able to
more accurately forecast flash floods. I’m going to
record my thinking on a cause-effect chain graphic organizer.
When forecasters use information, it causes them to
accurately forecast flash floods. In this example, there is a single
cause, which has a single effect. In the next
sentence, the author uses the single words
“result in” to tell me that more events will happen. When
an accurate forecast can be made (cause), then watches and warnings
are sounded to alert the public (the effect). Making an
accurate forecast of a flash flood was the effect of
using information. Now, it causes warnings to be sounded.
This graphic organizer records the continued
chain of cause-effect relationships. In the last sentence,
“due to” helps me understand another
cause-effect relationship. By sounding the warnings, now a
cause, lives are saved, the effect, but then I noticed another signal word, “if,” which signals a cause. I realize that
in this last part of the sentence, the effect
came before the cause. Lives were saved, the effect; because people had time to evacuate to
higher ground, the cause. I record the events as they
actually happen and not in the order they
were written. It really helps to map it out. – [Paige]Interesting graphic
organizer and interesting book. I always pay attention to weather signals.
I guess I should pay more attention to signal words in written
text as well. – [Reed]It always helps! Let’s see this thing in action!
– [Paige]Okay! [laughter] [rolling sound] [ringer sounds] [squeaking] [creaking] [bouncing sound effect] [laughter] – [Narrator]As we close the chapter on flash floods and cause and effect
text structure, be sure to continue watching for the signal words and remember
that authors use text structure to help them relay information to
the reader in a concise and more understandable way. A Knowledge Seeker’s work is never
done! Be sure to watch the next episode of Thinking Aloud!
