Kinetic And Potential Energy.

Types of Energy - complete the chart

Energy is due to position or movement of an object - Kinetic and Potential

Forms of energy	What is it?	Example?
Kinetic energy	Energy in movement
Mechanical energy	Makes things move by workable moving part or parts.	Wind up toy, scissors.
Thermal energy	It comes from heat. Heat is generated from tiny moving particles.	Fire, boiling water etc, stove, the earth's core, the sun.
Magnetic energy	Energy from attraction of objects made of iron.	Magnets, magnetic force, magnetic fields.
Electrical energy	Can be used to move particles through wire from a power plant to our houses and workplaces etc.	Appliances in your home, power plants, electrical currents.
Potential energy	Stored Energy
Gravitational energy	Energy stored in objects held above the earth’s surface.	People dropping things.
Elastic energy	Stretched or squashed objects.	Slingshot, spring and rubber band.
Chemical energy	Is energy stored in chemical compounds and is released in a chemical reaction.	Batteries, petrol.
Nuclear energy	Energy stored in the nucleus of an atom.	Nuclear power plant - provides electricity.

Hexagons

On Tuesday we had to connect hexagons together about moving things, gravity and lift. We placed these based on their connection with other hexagons.

Self Defence

On Thursday 4 May all the year 7/8 girls participated in a self defence course. We learnt about what to do when people (usually a man) grab you and try to pull you away or along with them, so what you do is either try to block them from grabbing you then grab them and lunge towards them and knee them with your knee or if they have already grabbed you then still try to grab them and knee them, if they grab you on the shoulders: block or grab them on the shoulders to lunge in for the kick, if they grab you on your arm: grab their arm and knee them using same technique, same with if they grab on both of your arms except just grab on wrists. We were also taught that if they grab you on your off side the do the same (grab them) except you spin while you kick and try to get them on the top of their knee with the side of your shoe or on the top of their foot where all the little bones are. Then we did a scenario where if a person (usually a man) stops their car and gets out to ask you for directions this is a sign that you need to get out of there fast, its a bit different if the person doesn't get out of their car but once you give them directions if they ask you where you live you just confidently repeat the directions.

Biking at Little River

   Little River Bike Ride

Routeburn class started training for the upcoming Little River bike ride on a Friday in March by biking to Lincoln University, we repeated this each Thursday or Friday until 24 March when we were doing the bigger bike ride. The training for me wasn’t to hard as I bike to Lincoln quite a bit.

Finally it was the day before the bike ride and I packed my rucksack, here is what I brought:

• Food/Drink
• Rain coat
• Bandanna (to keep flies from getting in my mouth)
• Sunglasses
• Sunscreen
• A polyprop
• Bike gloves
• Bike helmet
• Bike

Friday 24 March Routeburn class was getting ready to bike the rail trail from Mandalay House to Motukarara. We loaded the bikes onto the truck as well as some on dad’s car and everyone got in the cars to leave, it was about a half an hour, 40 mins drive.

When we got to where we were starting, we unloaded the bikes and the parents left to take their cars to the end while the parents that weren’t biking, took the parents that were biking to the start again then went back to Motukarara themselves.

Starting the rail trail everyone kept together in one big group until the faster people started gaining speed to get away from the medium and slower bikers. After a while my legs had started getting tired but my adrenaline was still pumping as I rode over cattle grids and small bumps. The good thing was that there were no flies around to bother us. However there were some wasps instead.

We stopped for lunch at a huge rocky hill/cliff and we all climbed up it to eat at the top. The view at the top was pretty good apart from the dying lake.

When we were finished with looking at the view and climbing, we began biking again, I kept up with dad the whole way to Motukarara.

When we got to Motukarara we all drank and ate lots, then got into the cars and drove back to school.
