4. 0:05the Earth is part of a special family
5. 0:08it's called the solar system and this
6. 0:11family is made up of eight very
7. 0:13different planets all of the planets
8. 0:16starting from nearest the sun is Mercury
9. 0:19Venus Earth Mars Jupiter Saturn Uranus
10. 0:25and Neptune what a fantastic family what
11. 0:29brings all these planets together is our
12. 0:31nearest star the sun each planet follows
13. 0:35its own path around the sun called an
14. 0:38orbit even though there are eight
15. 0:40planets moving around at once they never
16. 0:42bump into each other that is impressive
17. 0:46some planets orbits around the Sun are
18. 0:48faster than others the Earth only takes
19. 0:50one year to orbit the Sun but Neptune
20. 0:53takes around 165 Earth years that's it
21. 0:57Neptune you take your time
22. 1:01gravity is an invisible force that pulls
23. 1:03everything on Earth
24. 1:05downwards but gravity isn't just on
25. 1:08Earth it's a force that pulls two
26. 1:10objects towards each other gravity is
27. 1:12what holds the Earth and other planets
28. 1:15in their paths or orbits around the Sun
29. 1:18and gravity is also what keeps the moon
30. 1:20in its orbit around the Earth the bigger
31. 1:23the mass of the object that's how much
32. 1:26matter or stuff it's made from the
33. 1:29stronger it's force of gravity because
34. 1:32the Earth has such a big Mass its force
35. 1:35of gravity is really really strong so it
36. 1:38is Earth gravity that pulls everything
37. 1:41on it down to the ground because humans
38. 1:45have much less mass than the earth we
39. 1:47don't really feel the force of gravity
40. 1:49so we can walk around on Earth quite
41. 1:52easily the moon also has a smaller mass
42. 1:54than Earth so the force of gravity on
43. 1:57the moon is less than the force of
44. 1:59gravity on Earth so if you were ever on
45. 2:01the moon you would feel much lighter if
46. 2:04you tried to walk around on it and
47. 2:06that's why astronauts move around like

50. 2:15planet Earth amazing it's a beautiful
51. 2:17planet over 70% of Earth is covered by
52. 2:20water and it's our job to look after
53. 2:23Earth and protect its precious resources
54. 2:26three ways we can help to do this are to
55. 2:28reduce re use and
56. 2:31recycle we can try to reduce the amount
57. 2:34of waste we produce by only buying
58. 2:36things that we really need saying no to
59. 2:38things we don't need and taking care of
60. 2:41what we already have we can think of
61. 2:44ways to reuse something like buying a
62. 2:46secondhand coat instead of a brand new
63. 2:49one we can also try repairing things and
64. 2:52give them a second
65. 2:54life recycling is when materials like
66. 2:57metal card paper and some Plastics are
67. 3:01used again to make new things instead of
68. 3:04being thrown away there are special
69. 3:06symbols that let you know how to recycle
70. 3:08an object and which bin to put them in
71. 3:11reduce reuse recycle trying to do these
72. 3:15three things as much as we can helps to
73. 3:18protect planet
74. 3:20Earth a year is divided into four
75. 3:23seasons spring summer autumn and winter
76. 3:28each season is about three 3 months or
77. 3:3012 weeks long you can notice the seasons
78. 3:34changing by looking at the trees around
79. 3:36you in Spring they can have colorful
80. 3:38blossoms and new leaves in summer all
81. 3:41the branches are covered in lush green
82. 3:43leaves in Autumn the leaves change from
83. 3:47green to oranges Reds and Browns and
84. 3:49fall to the ground leaving the tree be
85. 3:52of leaves for winter until the spring
86. 3:54arrives again you might also notice that
87. 3:57the weather changes when the seasons
88. 3:59change spring and summer are usually
89. 4:01warmer and autumn and winter are usually
90. 4:03cooler but why do the seasons change
91. 4:06it's to do with the way the Earth orbits
92. 4:09or moves around the sun which takes a
93. 4:11full year to complete planet earth has
94. 4:14an invisible line through it called an
95. 4:16axis when the earth orbits around the
96. 4:19Sun it doesn't stand upright it tilts on
97. 4:22its axis for part of the year one half
98. 4:25of the earth which is called a
99. 4:26hemisphere is closer to the Sun meaning
100. 4:29the season there are warmer and for the
101. 4:31other part of the year that hemisphere
102. 4:33is further away so the seasons are
103. 4:36cooler so when it's summer in the
104. 4:37northern hemisphere on the other side of
105. 4:39the planet in the southern hemisphere
106. 4:41it's winter and that's what causes the
107. 4:43changing
108. 4:45seasons bees love flowers They're
109. 4:48attracted by their bright colors and
110. 4:50interesting smells the bees land on the
111. 4:53flower and use a long tongue called a
112. 4:55prosis to suck up a sweet liquid called
113. 4:58nectar as the bees feed on the nectar
114. 5:01their legs rub against the flow covering
115. 5:04them in pollen the bees then carry that
116. 5:07pollen to the next flower they're
117. 5:08attracted to and the pollen stuck to
118. 5:10their legs rubs off onto that
119. 5:13flower this process is called
120. 5:16pollination and is how flowers produce
121. 5:18seeds which fall to the ground and make
122. 5:21new flowers grow when the bees have
123. 5:24collected the nectar they go back to
124. 5:26their hive and do a waggle dance this
125. 5:29tells the other bees that they found
126. 5:31lots of tasty nectar and how far their
127. 5:33friends need to go to find
128. 5:36it energy is what makes things happen
129. 5:39it's what gives objects the ability to
130. 5:41move light up bounce or spin like this
131. 5:46wind turbine it works by capturing
132. 5:49energy from the wind to turn its big
133. 5:52blades which are used to make
134. 5:55electricity that electricity connects to
135. 5:58our homes providing energy that we can
136. 6:00use for things like light bulbs washing
137. 6:03machines and the screen you're watching
138. 6:05right now even you need energy to do all
139. 6:08the things you do like running or moving
140. 6:11around learning and even playing hide
141. 6:15and seek and you get that energy from
142. 6:18food loving that
143. 6:20energy learn more with cbbs on the BBC I
144. 6:23player app download it today Shadows can
145. 6:26be really fun a shadow is the dark shape
146. 6:30made when something blocks light from a
147. 6:32light source like the Sun or a torch
148. 6:35that's because light travels in straight
149. 6:37lines so it can't go through an object
150. 6:39or go around
151. 6:42it where the light is blocked a shadow
152. 6:45is made of the same shape the closer to
153. 6:48the light source the bigger the
154. 6:51shadow sometimes Shadows might look like
155. 6:54one thing but really there's something
156. 6:57else Shadows really are
157. 7:00fun every sound you hear is made by
158. 7:04vibrations whenever you hear something
159. 7:06it's because vibrations are traveling
160. 7:08through the air and being picked up by
161. 7:11your ears which then pass that
162. 7:13information to your brain your brain is
163. 7:15really smart it can interpret what
164. 7:18different vibrations sound like these
165. 7:20vibrations are called sound waves and if
166. 7:23you were able to see them they'd look a
167. 7:25bit like this the louder a sound is the
168. 7:29bigger the vibration it makes which is
169. 7:31shown by a bigger sound wave the quieter
170. 7:34a sound is the smaller the vibration it
171. 7:37makes which is shown as a smaller
172. 7:40Soundwave pitch tells us how high or how
173. 7:45low a sound is the pitch of a sound
174. 7:48depends on how fast or how slow the
175. 7:52vibrations are the faster the vibrations
176. 7:54the higher the pitch and the slower the
177. 7:57vibrations the lower the pitch
178. 8:00so sound is made by vibrations and it's
179. 8:03why you're able to hear me say this
180. 8:05sentence and this one and this one too
181. 8:08and also this one sorry I'll stop now
182. 8:12everything is made up of matter matter
183. 8:15is another word for the stuff things are
184. 8:17made from everything around us
185. 8:19everything you can see and touch is made
186. 8:21of matter anything that takes up space
187. 8:24is called matter air water rocks and
188. 8:28even people are examples of matter and
189. 8:31how much matter something is made up of
190. 8:33affects how heavy or light it will be
191. 8:36scientists use the term Mass to measure
192. 8:39exactly how heavy or light an object is
193. 8:43you might think bigger objects are
194. 8:45heavier and have a bigger mass than
195. 8:47smaller ones because they're bigger in
196. 8:49size like this hippo but that's not
197. 8:51always true sometimes bigger objects can
198. 8:54have less mass than smaller objects like
199. 8:57this balloon and this banana for
200. 8:58instance the balloon is full of air so
201. 9:01it actually has less mass than the
202. 9:03banana because the banana is solid and
203. 9:07that is why Mass
204. 9:09matters learning can be so much fun and
