Conduction
For the whole term 1, we have done a total of 4 experiments. On those 4 experiments, they were all involved with heat, like the first one we did, the first one was conduction, where we set a Bunsen burner and got a retort stand to hold a rod. Then we got pins and stuck the pins under the rod with the use of jelly, then we turned on the Bunsen burner, heated up the rod, and then the pins fell down because of the heat, we recorded when the pin fell down. This experiment showed us how hot particles can spread to other particles.
Contraction
The next experiment was about contraction, where we set a Bunsen burner again with a tripod and placed an aluminum can filled with a bit of water, we also got an ice cream container filled with cold water, so first we needed to heat up the can so the water inside it can steam up, after its steaming we had to wait 30 seconds, after 30 seconds we got out tongs and picked up the can with it and then tilt the can pouring the hot water in the can go to the cold water in the ice cream container making it implode.
Convection
The third experiment we did was to see how convection works in a liquid, so again we needed to set a Bunsen burner with a tripod on top of it, holding a beaker with 200 mL of water in it, we turn on the bunsen burner on and then put the potassium permanganate in it through a straw. The water turned purple, we saw the water shift the more it got hotter, we saw the potassium permanganate rise up the surface. This experiment showed that the hot particles does to thee top but in the other hand the cold particles go down.
Diffusion
In this latest experiment, we did, we wanted to see how diffusion works. first step we needed to get two petri dish, one is filled with hot water and the other one filled with cold water, and then the teacher drops the potassium permanganate in the hot water and the cold water, we started the timer as soon he placed the potassium permanganate in it. The potassium permanganate in the hot water started off hot, and the cold one was slow. In the end the cold one spreaded fully first, but the hot one spreaded fast at the start.
