The Scientific Method
Jim wants to conduct an experiment to see if light will reflect off different materials. What does Jim have to do before starting his experiment?
What is write a hypothesis?
This is the main energy released by a neon sign.
What is light energy?
An apple is an example of this kind of energy.
What is chemical energy?
Māori used pungapunga (pumice) to carry embers to light fires with because it is this.
What is an insulator?
A light bulb turns this electrical energy into this kind of energy.
What is light?
This is what we are measuring in an experiment.
What is the dependent variable?
A light bulb, a toaster, a phone, and a laptop all use this type of energy.
What is electrical energy?
This is the type of potential energy found in a compressed spring.
What is elastic energy?
One of the methods of cooking large amounts of kai was to bury it in the ground with hot stones. This is the method which traps the termal energy.
What is hāngī?
Your body uses this kind of energy from your food and turns it into motion and heat.
What is chemical?
Jasmine is doing an experiment to find out if plants grow better with rock music, country music, or no music. This is the independent variable in the experiment.
What is the type of music?
This type of energy is caused by vibrations, travels in waves, and is sensed by us through our ears.
What is sound?
This is the energy of motion.
What is kinetic energy?
The energy held within stars, such as those that form matariki is this.
What is nuclear energy?
A windmill turns this kind of energy into electrical.
What is kinetic?
Natalia conducted an experiment to learn more about the chemical energy stored in food. She measured the initial temp. of water and then burned a piece of food to heat the water. This is why she may get a different result for the same test.
What is the different size of food? / What is the distance she held the boiling tube from the flame?
A thermometer measures this kind of energy.
What is thermal energy?
This is the reason pungapunga is a good insulator.
What is gas trapped in the rock?
A toaster turns this kind of energy into this kind of energy.
What is electrical energy into thermal energy?
These two words should always be a part of your hypothesis.
What are "if" and "then"?
If you imagine a drop of water about to fall down a waterfall, at the top of the waterfall the drop of water has this kind of energy.
What is gravitational potential energy?
This is stored energy.
What is potential energy?
The method of cutting down a totāra tree requires a pendulum with a toki attached to the end. This would be brought up and released to slam into the tree, carving out a notch. This energy is being transformed into this energy.
What is Gravitational Potential and Kinetic?
This kind of energy is given off in every energy transfer.
What is thermal energy?
