Acid Rain Experiment

Acid Rain Experiment 

What is acid rain? Acid rain is when the air gets so polluted with fossil fuels it gets absorbed by the clouds and comes out in an acidic form when it rains, it is environmentally harmful.

Aim: To observe effects of acid rain

Hypothesis: Petal- dry out calcium carbonate- become liquid apple-dry out, universal indicator- get dark bromothymol blue- lighten. 

Method: In a petri dish place items around weigh boat which is in the middle of the dish, wet-dry ingredients with a drop of water.  Add a spatula of sulfate to weigh boat, add 5 drops of sulfuric acid. quickly close. 

observation: bromothymol blue is turning yellow/orange, the universal indicator is turning pink, the petal is getting slightly lighter. I think it's because acid eats way at things so it diluted the colour.

It sounds different to music in the '40s mainly because it's more upbeat, it was new and older music is more on the classical side. 

My weekend

 During the weekend I stayed at Paige's, it was quite boring because Paige is boring, she was babysitting so we didn't do much but we played a board game and watched movies, we also started annoying some people from school, because we were bored. Then on Sunday, I went out for lunch with my father. That was all I did, it was relatively boring.

It's a way of remembering the soldiers who fought and who died over at war.

The Last Post is played at commemorative services as a final goodbye, it also symbolizes that the duty is over and that they can rest in peace.

Athletics Day- Reflection section

 Last Thursday we had athletics day, Paige. Mya and I are all in Tieke and our house colour is red, so we dressed up in red clothing. For our events we had discus, long jump, high jump and a 60-metre sprint, we missed long jump and discus because we didn't know what our times were but went to high jump and the 60-metre sprint. Because we were in social athletics and not competitive, we didn't have many activities to go to, so we mainly just watched the other people run. Towards the end of the day they had relays, first, it was each Kahui vs each other and in the end it as the seniors vs the teachers, which was the most interesting part of it all. In the end, I think Mohua won and Tieke came second. 

Atomic Science: Periodic Table

 What does the periodic table show us?

The periodic table shows us the elements, it is arranged by their atomic numbers and electron configuration 

What is a mass number? It shows us the mass number which is the number of protons and neutrons in a nucleus. 

What is an atom? An atom is a very small particle that makes up everything around us, it consists of three particles, electrons, protons, and neutrons. 

What are alkali metals?  An alkali metal is any of the six chemical elements that make n Group 1 of the periodic table. It's the first collum on the periodic table-  lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr). They react with other elements because they want to get rid of the one-electron they have. 

What happened during the demonstration? The teacher put lithium into the water and it changed the colour, then she used sodium and it created a small fire on the water but in the end, it made a small explosion.
