Hi kids! Today we are going to do an experiment to revise the concept of mass. 00:00:01
Do you remember what mass means? 00:00:07
You're right! The mass is the amount of matter an object has. 00:00:11
And we know because of its weight, el peso. 00:00:17
We are going to do an experiment to check this. 00:00:23
For this experiment you'll need the following. 00:00:27
okay you'll need a hanger okay this is a hanger you'll need two plastic recipients and two paper 00:00:29
clips like this okay then we are going to put this on a hanger door and we are going to choose two 00:00:44
objects to compare. I am going to choose a battery and a marble. Let me see, here I've 00:01:02
got a battery and a marble. So I am going to put the marble here, okay, it 00:01:14
doesn't have much matter and I am going to put the battery on the other side. 00:01:29
What happened? The battery has more mass than the marble. Now I am going to choose 00:01:37
two different objects I am going to choose a rubber ball and two magnets 00:01:54
here is the ball and here the two magnets okay these are magnets so I have 00:02:05
two magnets and a rubber ball I am going to put the ball in the box okay this has 00:02:17
move to the right. Now I am going to put the two magnets on the other side. Let's 00:02:29
see what happened. Okay, the ball has more mass than the two magnets. I am 00:02:37
going to take two more magnets. So we have one green ball here and two 00:02:49
magnets over there, but I am going to pick two more magnets. Now I'm going to 00:02:54
put the two magnets with the pink ones and see what happened to the hanger okay 00:03:04
now the balance is more or less the same okay so now four magnets have more or 00:03:13
less the same matter than the ball I am going to take two more magnets and see 00:03:22
what happened. Here I've got two magnets more and I am going to put it with the pink and the blue 00:03:30
ones. What happened now? You're right. Six magnets have more mass than the green rubber ball. Hope 00:03:42
you have learned a lot. Now I want to see your experiments. Bye! 00:03:56
