>> Hi, this is Lesson Plan Number 5:
Gravitational Forces on Rockets in Space.
The rockets have so much mass that it requires
almost 7.2 million pounds of thrust in order
to get that rocket to release
from Earth's gravitational hold.
This is one of NASA's videos, and it explains
about how much energy is
required for these rockets.
On the website, students have the opportunity
to see other Deaf students there are signing
about gravity and explaining what gravity is.
And it gives students the
opportunity to video themselves
and give an interpretation
of gravity here on Earth.
Make sure to use TeacherTube.
This is a safe website that students can use
to upload their work whenever they're finished.
So they can video themselves on a laptop or any
sort of computer and after they've done that,
then they can upload that up to TeacherTube.
And these are some things to think about: what
they can do with the video, where they can look
at other videos, and analyze the
explanations and interpret that.
So I think TeacherTube is a safe
website to use for uploading videos
and there's the website available here
that students can use to gather information
and how they feel about the
explanations they see.
And here it is talking about
those explosions that are used
to carry those heavy rocks out into space.
This is an interesting video; it shows
this rocket's last trip up into space.
It takes about 8 minutes in order for the rocket
to get to space and it's an outstanding video.
It does a really good job of
explaining things clearly.
I really like this one.
