Science
A question that our teacher ask us to fined the answer to was: What is pulse rate/heart rate?
The answer i gave was: The What is pulse rate/heart rate is the number of times your heart beats in one minute.
what you need: Smart stopwatch, tennis ball and a stop watch. We did a range of tasks some that made our heart rate go low or mad our heart rate go fast. Like for example running made my heart beat faster and sitting down makes my heart beat slower.

Acids and Bases
Today in science we learned about acids and bases. Here are some question that the teacher wanted us to think about:
What is pH?
How do you measure pH?
What is the scale of pH is measured on?
What pH level does water have? Is water acidic, basic or neutral?
What is the most acidic pH level?
What is the most basic pH level?
Something else the teacher also told us s some facts is the most liquid is ether an acid or base depending on the type of Ions. The different types of ions we have learnt so far is hydroxide ions hydrogen ions. She also told us that the pH scale is always 0 to 14. And that usually acid is bad but all acids are bad like lemons, grapes and oranges, they have citric acid

Sugar cane
Sugar cane
Today we were lucky enough to be eating sugar cane because sugar cane doesn't usually grow in New Zealand more in the pacific islands because it was warmer there, so to be eating the sugar cane is very lucky.
Lots of people said that the sugar cane was not as sweet as they remember, but I had never had sugar cane before so I had nothing to compare the sugar cane to.
Bubbles
Topic 5: Bubbles
How to make bubbles:
One part water, one part soap, and some glycerol to make the last a little longer
Task 1:
Make a caterpillar bubble.
How it worked: The caterpillar was much harder than I thought that it would be. A tip that the teacher gave to us is we should be using the different sized straws for the different bubbles as you go down. Then something that I learnt on the way is that you need to be quick or it will drop.
Task 2:
Make a carousel bubble.
How it worked: Every time that I tried to spin the carousel I just pop the bubbles. A tip the teacher gave us is to blow gently and slowly because the more that you blow the faster that it will get.
Task 3:
Make a cube bubble.
How it worked: This one was very easy and entertaining. The bubbles stuck together very well and seeing the cube in the middle was very cool. It was very interesting seeing the different shapes and not seeing the original sphere and cylinder.
