Mechanics often use
_________ such as oil to
decrease friction.

9. lubricants

10. If 2 cute toy robots push a box in opposite directions with one robot pushing from the right and the other robot pushing from the left, the box does not move because the forces are…

11. balanced.

A(n) _____ is a
piece of rock or metal that has entered the Earth’s
atmosphere.

13. meteor

Mars and Jupiter.

18. Comets are similar to planets
because they both
________ the sun.

19. orbit (revolve around)
Note the planets, comet on the left, and the Asteroid Belt are all orbiting the Sun.

20. Inner planets are like asteroids
in that they are both
r____y and d_____e.
asteroids
Inner Planets

21. rocky and dense. (Compare the 4 ROCKY inner planets to the
four giant GAS outer planets.)

22. The Hubble Space Telescope is a space-based telescope that is able to take more accurate _______ than Earth-based telescopes.

23. photographs
Cluster of galaxies
Nebula

24. What is an advancement in technology that has greatly improved how we predict the weather?

25. weather satellites

26. Due to space exploration, many scientific developments
such as disease research, lasers,
and pacemakers have benefitted
_________ _________.

27. medical care
Pacemaker
for the heart.
Laser surgery.

28. If scientists wanted to visit
a planet far away like
Neptune, they would send a _____ _____, because it would be too far and too dangerous for a crew of astronauts.

29. space probe A drawing of blue Neptune with its largest moon at the
bottom right. The artist has
drawn 3 space probes near
Neptune and its moons. (The moon only seems bigger than Neptune because it is
closer to you. )

30. What is the name of
the scientific research
facility that orbits the Earth
in outer space?
Many countries around the world support it.

31. The International Space Station

32. “manned, launched rocket” was built in the
The first
“manned, launched rocket” was built in the
state of _________.

33. (Huntsville is in north Alabama.)

34. Alabama is home to the first African-American female astronaut
Alabama is home to the first African-American female astronaut. Her name is ___________.

35. Dr. Mae Jemison

36. The Hubble Space Telescope was developed by a group of scientists in
Alabama known as the _________.

37. Marshall Team.

38. In Huntsville, Alabama, this is the place where scientists
work on the space program for NASA.

39. Marshall Space Flight Center

40. scientist, who developed
Who was the key German
scientist, who developed
early American rockets at the Marshall Space Flight Center?

41. Dr. Wernher von Braun

42. What is a smooth surface with very little friction,
good for sliding or skating?

43. ice.

44. than at the poles. Therefore, the equator will be _____
The sun’s rays are more
direct at the equator
than at the poles. Therefore,
the equator will be
_____
in temperature than the poles.

45. warmer Eleanor M. Savko 11/11/2018
Shine a flashlight onto a black piece of construction paper. Direct light is brighter and equates to Sun.
Hold the flashlight at an angle to the black paper; the light dims and is more spread out = poles.

46. An object that orbits
another object in
space is called a
_______________.

47. Human-made weather satellites
The moon orbits
the Earth so
it is Earth’s
natural satellite!
Human-made weather satellites
also orbit the Earth.

48. rest tends to stay at rest?

What word describes
the idea that a thing in
motion tends to stay in
motion and a thing at
rest tends to stay at rest?
Show a pendulum (washer on a string). It moves a long time because the only friction it encounters is air resistance and gravity. Compare that to a heavy table. Both show inertia. It is the reason why we need seatbelts: the car stops suddenly and those in the car keep traveling the former speed of the car.

49. Eleanor M. Savko

inertia
(A chest of drawers at rest doesn’t move unless lifted or pushed.
Planets orbit the Sun and continue
orbiting because there is little or no
friction to slow them down.)

50. Two dump trucks are going down the same hill
Two dump trucks are going down the same hill. One is empty, and one is filled with heavy rocks. Which truck will build more momentum as they go down the hill?

51. The truck with the rocks builds more momentum.
Eleanor M. Savko
11/11/2018
The truck with the rocks
builds more momentum.
More mass / more momentum,
making it harder to stop.
Toy trucks on a ramp will not demonstrate this. The added weight will bear down on the wheels and slow the truck. You need a truck with wheel bearings, made to hold the weight off the wheels. Also, think of an 18-wheeler; you don’t drive too close because it takes a long time for it to stop. A very slow moving wrecker ball is still very hard to stop because of its mass.
