Parihaka

 Bonjour Bloggers,

In Hurumanu 1 we have been learning about the people. We learned about protests like Kate Shepard and how she stood up for women's rights and others like The Great Depression or the Vietnam War. But one protest that really stood out to me is the Parihaka one. 

In Hurumanu one with AL(Miss Allan's class) we learned about Parihaka. We split into groups of five or less to solve a puzzle. We had to answer the questions on the puzzle pieces. 

Basically to summarise: the Parihaka protest is about how the Pakeha were trying to take the Maori land. They kept confiscating what wasn't their.s So the Tangata Whenua people tried to rise against them and lived on land that belonged to them in the first place, even though they were't allowed on. After some months the Pakeha found out and tried to attack the Maori. Instead of defending they fed the soldiers and invited children to welcome them. However, the Pakeha still sent them to jail. After a few years the Pakeha apologised and Parihaka became a sign of peace.

Goodbye

Results

I saw... the fire emerge and disappear. It was bright red and yellowy orange. It went straight up and dissipated when I put my hands out.

I heard... other people being loud and somehow the sound of the fire getting burned.

I smelt...the heat from the fire. It smelt burnt and gassy. Even when the fire went away the smell remained.

I felt... excited and nervous. My heart was beating so fast. It was great and so much fun.

Safety in the Lab

           Hola viewers,

1. Liquids do not go in the bin because it could leak out of the bin or be to heavy for the cleaner to take and make a hole.
2.  Solids do not go down the sink because it could block the sink or pollute the water.
3. Wear safety glasses when you do experiments because dangerous stuff like chemicals or fire could get in your eyes.
4. Put your chair under the desk, and stand at the bench when you do experiments because its better to do that.
5. Bags do not go on desks because chemicals or stuff like that could get inside your bag.
6. Long hair should be tied back because it could be caught on fire and you could become bald.
7. Do not smell the chemicals because all the chemicals would get in your lungs and you could pass out.
8. Walk, do not run around the room because you could trip over and hit some chemicals or break your arms 
9. Do not eat or drink in the lab because you could swallow germs and poison yourself.
