Mount Tarawera 

A powerful jolt shook the ground. Mud hit water causing violent explosions. Frightened people staggered through the pitch black darkness. I screamed as another explosion took place. The wind howled. What should I do now? Other children around me started crying as lava spurted into the air. I was petrified. I tried to run to my parents, but I wasn't strong enough. Now I was alone. My heart pounded as I stumbled through the sticky ash. The ground jerked yet again, and smoke rose into the air. The sky lit up as molten lava squirted out of the volcano. A ball of fire landed beside me. I hurridly jumped away as everything around it burst into flame. I heard a shout. It echoed and then faded into the blackness. Was it my parents? Then suddenly, they appeared out of the   smoke, coughing and spluttering. I heaved a sigh of relief. it was them - My parents.

Leaf Colour Reflection by Maia

We have been reading how leaf colour changes and we found that it involves 3 really interesting and different pigments all of which have different jobs, and light that they absorb.
This is Maia's reflection:

Chlorophyll

Lucas has been reading about the role of the pigment Chorophyll. This is his keynote slide showing his understandings about his pigment. Do you have any comments or questions?

Anthocyanin

In our reading groups we have been researching about chlorophyll. caretenoids and anthocyanins. Here is some of the research I have done about anthocyanin. Anthocyanin is a chemical that is often found in flowers or foods and occasionally trees. It's found in blueberries, cranberries, raspberries, blackberries, cherries, eggplant peel, black rice, red cabbage, violet petals and ripe olives. Do you have any comments or questions?

Questions about the endothermic reaction.

(If you know the answer if you could comment them that be great!)


What if you put the endothermic reaction in a fire?

Would this experiment work with other liquids other than water?

If you drank it when the reaction started what would happen,would you get sick?

Is this mixture on the periodic table?

Who and how discovered the endothermic reaction?

Why is this reaction useful?

Do you have comments? Or questions?

Swimming Sports

As my eyes were glued straight ahead, people's voices started to fade when I heard the blocks go clatter, BANG!  My heart started thumping like a drum and my eyes squinted as I looked at the stone solid pool floor.  I heard kids shouting 'lets go bears, lets go,' like a monkey talking.  At the end of the race we finally hopped out.  'What a splash' I sighed.
