Sleep and exercise teenagers

Hi everyone I hope your having a good day  and enjoy reading about what my class and I have been learning about in our health class with Whaea Raywen, Most teenagers eat really unhealthy food like candy, chips, salty foods and energy drinks when at our age we should be focusing more on eating things like all your greens if you eat meat or what how ever you get your iron and lots of water and making sure you have plenty of dairy each day. Sleeping is very important because we need it for our growing brain once your going through your teenage years that when you do your most growing so need a good night sleep and that means 10 hours or more of sleep and try not go on technology any  about an hour before your about to go to sleep. When we were watching our video two points that i really liked were that the more active you are the bigger your heart gets and grows because it needs to pump more blood around the body. And the second one is that you need at least 150 mins of exercise and active each week and every 10 mins count.

 Kia Ora Readers,

Today we are doing an experiment on cabbages.

1.3 pieces of cabbage.

2.Beaker

3.Set up Bunsen Burner.

4.50ml water.

5.Pipette.

6. Hydroxide Acid.

7. Test Tubes (5x).

8. Hydrochloric  Acid. 

9. Test Tube (5x).

10.Paper towel.

11. Test Tube Rack.

12. Water.

Steps:

1.Chop up the red cabbage into small pieces. Place in a beaker and cover with a small amount of water.

2.Bring the solution to the boil using a Bunsen Burner and then turn off the heat. Let it sit to cool down.

3.Pour the cabbage water through a paper towel into a beaker. The dark purple liquid in the jar is the pH indicator liquid.

4.Suck up the indicator into a pipette.

5. In the test tube, use the cabbage indicator and the pH chart below to test the acidity of the hydrochloric acid and ammonium hydroxide.

5. at taste test one you need to hold your nose,
answer 1 is it sweet sour salty bitter, record it 
answer 2 what do you think it is record it 
6. repeat this for the next samples but you will only need to use your ice cream stick taster for sample 1-4

To learn about bacteria and how they grow

Equipment:

1. Agar dish

2. Cotton bud swab

3. Vivid pen

   Method:

   1. Collect the bacteria on a cotton bud swab from taps, computer keyboards or desks.

   2. Divide the agar in half by drawing a line open the lid.

   3. Wipe the swab onto the agar solution.

   4. Put the petri dish into the incubator for 1 week to allow the bacteria to grow.

   5. Draw and label a bacteria.

   6. Draw and label a scientific diagram of the experiment.
