Washing machine timeline

In hurmanu 3 we have been talking about inventions. This weeks tasks was to create a timeline of something that has improved over the years.i chose the washing machine and it improved from hand wash to technology that we have today. 

Science experiments

 Aim: To demonstrate how to heat liquid inside a test tube.

Equipment:Bunsen burner,Heatproof mat,Lighter,Test tube,test tube tongs and safety glasses.

Method:

1 Light the Bunsen burner  

2 Fill your test tube to approximately 5 ml water 

3 Turn the collar at the Bunsen so it is a blue flame

4 Holding the test tube with the test tube tongs tilt the test tube on a 45 degree angle an and place the bottom of the test tube into the flame ensure that the mouth of the test tube is facing towards others.

5 Gently wave the test tube in and out of the flame remember you are trying to heat the liquid gently 

6 Once the water starts to gently bubbly,take is away from the flame carefully pour the water into the sink.

Invention

 In hurmanu 3 we have been learning about inventions today task was to crate your own invention to help the planet in sort of way. I made a robot that plants trees in forest,park and empty grass area. This would help the planet to generate good clean air.

The purpose of this invention is to plant trees in empty spot in the forest.

It is made out of carbon fibre.

Operate from the city council

It last a week then when it gets low on charge it goes back to it charging dock 

It would be used i a forest or in empty land marks 

This is a quick making of the robot

Hand on fire

Hands on fire

Aim:

I want to safely light my hands on fire 

Before we this activity safely we need to be aware of the safety features.

Activity: In pairs you need to come up with a list of 5 safety items that to be included when doing this experiment.

1. Put on safety glasses 
2. tie up long hair 
3. make sure you have a fire extinguisher near by
4. Put some water into a tray
5. squirt some detergent into the water 
6. wet your hands, wrists and arms 
7. Bubbles the gas into the water 
8. scoop the bubbles but not the water 
9. hold the bubbles in front of your face with your arms locked
10. light the bubbles on fire with the lighter
11. to get rid of the flame put your hands into an iron man pose

While i was doing the experiment 

I saw the burning hot flame rising from my hands.

I felt the the flame burn my hands.

I heard the flame rise and other kids talking.

I smelled the the after smell of gas on my hands.
