1 00:00:00,000 --> 00:00:01,560 We are scientists. 2 00:00:07,870 --> 00:00:20,089 The green color is for the chlorophyll. 3 00:00:21,089 --> 00:00:24,449 The chlorophyll is in the leaves. 4 00:00:27,460 --> 00:00:32,340 Chlorophyll has many pigments. 5 00:00:33,200 --> 00:00:36,780 It is a special solar panel. 6 00:00:37,420 --> 00:00:43,159 This energy is used to cook the food for plants. 7 00:00:44,179 --> 00:00:49,679 With this practice, we are going to look for different pigments in the chlorophyll. 8 00:00:52,659 --> 00:00:55,039 We need all these instruments. 9 00:00:55,240 --> 00:01:03,840 Paper. 10 00:01:04,900 --> 00:01:05,939 Test tubes. 11 00:01:07,239 --> 00:01:08,480 Graduated cylinder. 12 00:01:10,260 --> 00:01:11,299 Two sticks. 13 00:01:12,079 --> 00:01:12,700 Alcohol. 14 00:01:13,420 --> 00:01:13,739 Pigs. 15 00:01:14,439 --> 00:01:14,859 Watch. 16 00:01:17,239 --> 00:01:26,379 Step 1. 17 00:01:33,290 --> 00:01:36,409 Cut them and pour 10 ml of alcohol. 18 00:01:36,409 --> 00:02:17,060 Step 2. It's time of the purple leaf. 19 00:02:17,060 --> 00:03:45,560 I'm going to do the same process with the purple pigments. 20 00:03:45,560 --> 00:04:22,959 Time is over. Now we put the green leaves and the purple leaves. 21 00:04:22,959 --> 00:04:27,959 The dark green color is the chlorophyll. 22 00:04:27,959 --> 00:04:37,879 The yellow one is another pigment, in the purple leaves we can see the purple pigment. 23 00:04:37,879 --> 00:04:56,209 Now our project is finished!
