Calibrating Clocks

Today in maths, the Year 5-7s made minute timers with water and milk bottles, this was a tricky experiment to complete! Jade and Ben got the closest with a timer that ran at 58sec. Do you think you could do it?!

Rainbow Jelly Maths - Part II

We completed our Rainbow Jelly maths learning by creating colourful layered jellies using our plans and measuring with cups, tablespoons and teaspoons. We 'sold' our jellies to the junior class - you can see that they really enjoyed eating them!

Rainbow Jelly Maths

Our maths strand unit this term is volume and capacity. As part of this we have been using teaspoons, tablespoons and cups to plan layered rainbow jellies that we will create, eat and sell. This week we have been planning and calculating the amount of millilitres of each colour we will need for each stripe in different shaped cups and jars. Next week, we create!

 

PLAN & CALCULATE

What colours will my layers be? How many layers do I want? How many millilitres will each layer be? What is the volume of my completed rainbow jelly?

Lung Capacity

Key: Blue - Ben, Black - Libby, Orange - Jor'jah, Red - Jakob, Green - Jade, Purple, Shannon.

Today we measured the capacity of our lungs with balloons and metre rulers. Each person blew up a balloon as much as they could on one breath and then we measured the diameter of the balloon. We did this three times and then found the mean of the three attempts. Then we graphed our results to find out our lung volume. Can you see who has the biggest lung capacity?!

Measuring Distance - Paper Planes

Maths Groups - Arctic Wolves and Great White Sharks
Today we are measuring the distance that we can get paper planes to fly. Use these links to help you decide on a design and then follow the instructions to help you create your plane.

Measuring Distance

Using two Hot Wheels cars and some pieces of wood we constructed ramps and measured the distance that the cars would travel...we found that is wasn't necessarily the steepest ramp that would send the cars the furthest or the smoothest surface! The furthest a car travelled was 3.53m!

More Than A Box - by Dave Armstrong

Over the last two days in maths and reading we completed a challenge. First we read "More Than A Box" by Dave Armstrong which was about the construction of the Wellington Indoor Sports Centre.

In maths we have been looking at 3D shapes and the special properties they have. We knew that triangles are the strongest shape and that you can make other shapes (like rectangles or squares) stronger by using bracing that creates triangular shapes within the original shape.
The first challenge today was to use a shape clue to find a QR code. When the code was scanned with a tablet it led to a Google Doc with the instructions on it. A web address from the Doc led to a shapes lab that helped remind us of the things we had been learning in maths and reading.
Then we had to complete the challenge by creating a structure using only newspaper and masking tape. The winning structure was the one that held the heaviest object - the winning pairs were Libby & Stuart and Charlotte & Jade!

 

Treasure Hunting at Pirate's Stream

This term in maths we are learning about direction and position. This week we had to complete a treasure hunt, following the compass directions to find the buried treasure. We had to collect stamps, gold dubloons and other things along the way!
Can you guess where we found the treasure?

 Here is the map of Pirate's Stream that we had to follow:

What do you think was in the treasure chest?!

Rain Gauge Update

Today we checked the rain gauge it had 25mm in it!

 

Marshmallow Maths

Today we were doing Marshmallow Maths, we were learning to read thermometers and estimate the temperature of water. We had to see what temperatures were the best for melting the marshmallows.

This is what you need...
Marshmallows,Water,Cups,Thermometer, a spoon and drinking chocolate.

What to do...
Fill your cup with water that is 75 to 40 degrees Celsius. Put in a tea spoon of drinking chocolate in and a Marshmallow. Wait until it has melted. You can time it and find all of the differences.
We found that the hottest water (75 degrees Celsisus) out of the Zip was the best for melted marshmallows.

It was a lot of fun and at the end we got a tasty treat!!!!
