Percussion

 Hello everyone, today in Counting The Beat Jaden, James, Nathan & I made music about percussion. We used an abacus, beanbags and we also used buttons on our keyboard. Press this button to play the music.

Gummy Bear Osmosis

Aim: I want to find out what happens to gummy bears when we  put them into different solutions.

Prediction: They will dissolve into the solution.

Equipment:

• 4 gummy bears of the same colour
• 2 petri dishes
• 1 marker pen
• water
• sugar water
• salt water
• electronic balance
• beaker
• measuring cylinder

Instructions:

1. Get your equipment.

2. Put on your safety glasses.

3. Using the marker pen, write the name of the condition on the petri dish. Dry, water, salt water, sugar water.

4. Weight the gummy bear and write the weight on the petri dish.

5. Measure 40mL of the solution and pour it into the petri dish.

Discussion:

Osmosis:

1. The normal water was transferred into the gummy bear the most.

2. The dry gummy bear lost 0.11 grams over a week.

3. The sugar water diffused faster than the salt water

Diffusion:

Diffusion is the movement of a substance from an area of high concentration to an area of low concentration. Diffusion happens in liquids and gases because their particles move randomly from place to place. Diffusion is an important process for living things; it is how substances move in and out of cells.

Hurumanu 1 Heroes

Hey everyone, today I am making a blog post to show most of the work I did in Hurumanu 1. Hurumanu 1 is about heroes and what are some of the characteristics of a hero. Here is what I wrote:

In Nga Tangata, Hurumanu 1 we studied the lives of some local, national and international heroes. A hero is a person or a group who is admired for their heroic acts or achievements. I made some slides about six sporting heroes. They were Ryan Nelsen, Chelsea Bremner, Richie McCaw, Valeria Adams, Lebron James and Serena Williams.

I also made some slides about a local hero named Don Beaven and he helped with Diabetes treatment & prevention in Christchurch. We read about a musical group called Crowded House. They were said to be ‘Heroes for One Day!’ when they performed in Christchurch recently. We discussed the meaning of ‘Hero Worship’. The Hero I worship is Cyborg. Some of the earthquake heroes from the 2011 Christchurch Earthquake were George Piper, Tony Tamekahau, Joseph Tehau Rohio, Evan McLellan and Kent Huxford.

I also wrote about myself as a superhero. My alias was Zoom, here is my story:

Hi, I’m Zoom. I am a social guy and I never get to school late! I am still getting used to controlling my speed, I can actually slow down time but it sometimes happens at the wrong times. Like I had a test and I finished early, there were ten minutes left but I accidentally slowed down time and it took a whole hour!

Skittles

Aim: To use water to extract the dye from skittles using the process of chromatography.

Materials: 

1. 5 Skittles

2. Water

3. Petri dish

4. Beaker

Process:

Step 1: Place the skittles into the petri dish around the edges.

Step 2: Pour 100ml water gently into the middle of the petri dish.

Questions:

Why do they bleed out at the same rate? It has the same amount of dye in it.

Why do the colors not mix together? The water is staying still.

My lnvention

Hi everyone, in Hurumanu 3 we have been creating our own invention and l created a teleporting machine so you can get to places easier. Here is the information.

-------------------------------------------------------------------------------------------------------------------------------

Name of invention: Teleporter

Purpose: lt can teleport you to the other teleport chamber.

What is it made of: It is made out of steel and it has special crystals to help the lasers detect you easier.

How does it operate: Once you press the green button, the door will close and it will start a ten second countdown until you teleport. If there is something in the teleport chamber you want to teleport to, when the timer reaches zero, both of you will teleport. The lasers will help to detect what to teleport.

Does it need charging/emptying/refilling: You need to charge it for 1 hour to get one teleport. You can get a maximum of 50 teleports at once.

Who would use it/Where would it be used: They will cost $50,000 so only rich people can buy them. Maybe the rich people will use it to get to the second floor.

Clocks

Hi everyone, in Hurumanu 3 we have been learning about the clocks, clocks are one of the inventions that changed the world. I have a google doc and google slide to share.

The Wheel

 Hello everyone, for the past week in Hurumanu 3 we have been learning the history of the wheel. The wheel is an invention that changed the world. I made a google doc of the history of the wheel and how the wheel is used today.
