Mathletics Awards

Room 1 have been improving their mathematical skills with the new 'Mathletics' programme. 

If you achieve more than 1000 points a week you will receive a Bronze certificate. 

If you achieve 5 Bronze certificates you will receive a Silver certificate.

If you achieve 4 Silver certificates you will receive a Gold Certificate.

These fabulous Room 1 mathematicians have achieved Bronze certificates this week!

Matariki - Maori New Year

Today at Ohau school we celebrated Matariki - which is the Maori new year.

We celebrated by having a shared Kai and a special assembly. 

Students families donated food that was then steamed in an above ground hangi - or Kai cooker. 

Each class make a collaborative piece of Art work to share at assembly. 

This was Room 1's Art work:

The green stars represent us at Ohau School. 

They say our names in Maori by using the phrase Ko Nikki ahau - which means my name is Nikki. 

The black stars have our hopes for the future written on them. 

The white stars have things that w are grateful written on them. 

These are some of the other classrooms art work.

Science Experiment - Oobleck

During our inquiry of - the structure of matter - Room 1 made Oobleck!

What is Oobleck? 

Oobleck is a non-Newtonian substance - which means that can behave like a solid or a liquid depending on how much pressure you apply to it.

How do you make Oobleck? 

Oobleck ingredients

• 1 part water
• 1.5 to 2 parts cornstarch
• Small amount of food coloring (optional)

Mix ingredients

• Start with the water in a bowl (or wading pool!) and add the cornstarch a bit at a time.
• Keep stirring until it has a gooey consistency. You may want to use your hands.
• When the oobleck is just right, slowly add food coloring, if you want. This can be a challenge to get it mixed properly.
• Play with it.

Before we made Oobleck - Room 1 made predictions about how it might react of behave when we do different things to it. 

When we made it, it was lots of fun! 

Miss Oldridge got a little too excited with the food colouring and...

It turned our hands GREEN! 

After our experiment we recording our results and concluded if our predictions were correct. 

Experiment - Elephant's Toothpaste

Today we observed Miss Oldridge making Elephant's Toothpaste. We then had to write down the procedure and learn about why it reacted that way.

1. Carefully pour the hydrogen peroxide into the plastic bottle using a funnel.

2. Add food colouring (approx. 8 drops) into the bottle.

3. Add liquid dish washing soap (approx 1-2 tablespoons) into the bottle and mix it around.

4. In a separate cup, mix warm water and dry yeast thoroughly for about 30 seconds.

5. Pour the mixture into the bottle and record your observations.

How the chemical reaction works

The chemicals created foam! Foam is awesome! The foam you made is special because each tiny foam bubble is filled with oxygen. The yeast acted as a helper, to remove the oxygen from the hydrogen peroxide. Since it did this very fast, it created lots and lots of bubbles.

Did you notice the bottle got warm. Your experiment created a reaction called an Exothermic Reaction – that means it not only created foam, it created heat!

The foam produced is just water, soap, and oxygen so you can clean it up with a sponge and pour any extra liquid left in the bottle down the drain.

This experiment is called “Elephant’s Toothpaste” because it looks like toothpaste coming out of a tube, but don’t get the foam in your mouth!
