Diffusion of Potassium Permanganate

Greetings Everyone, 

Today I'm going to share with you what we'd on our hurumanu 3 class. We'd diffusing the potassium permanganate for today's experiment. 

The equipment that we'd used are Tweezers, Petri Dish, and KMnO4. Potassium Permanganate is also the same formula as KMnO4.Our aim for this experiment is for the temperature to speed up or slow down the diffusion. We'd put cold water and hot water on the petri dish and put the KMnO4 anywhere on the petri dish. The hot water experiment results diffuse the KMnO4 faster and spread out the KMnO4 than the cold water. The cold water diffuses slightly slower than hot water and doesn't really spread out the colours around.

Rising Water

 Greetings Everyone,

Today I'm going to share with you this blog post. This blog post is about an experiment that we did call Rising Water. The materials needed are Petri Dish, Candle, Lighter or matches, Cup, and Water. This experiment aims to see what happened to the water level when the candle is covered. In my prediction, the water level is a little bit higher and a little bit longer for the candle to die. For the result of our experiment, I saw the water level rise and the cup is stuck on the water. When the air is hot in other words high pressure, the water level is probably higher than cold air. When It has a low pressure, which is the opposite of the high pressure, it'll have less water.
