Diffusion of Potassium Permanganate

Hello! Welcome back to another Wednesday Science period! Today we did a little experiment resonating with diffusion, here's what I used!

Equipment:

Tweezers

Petri Dish

KMn04 (Potassium)

Cold & Hot water

Question: Does temperature speed up or slow down Diffusion?

Result/Observation: Crystal in the hot water grew and expanded 2x the size of the crystal in the cold water. Why? The particles in the hot water are moving faster than the particles in the cold water, which means that diffusion will happen quicker. 

Conclusion: The experiment was interesting because that was the first time I had seen something like that. It was also cool to see the effect the different temperatures of water would have on the potassium permanganate.

Chemical Reaction - Elephant Toothpaste

Today for Science we did an experiment called Elephant Toothpaste.
This Google Drawing shows what we did.
The hardest part as usual was to make sure the labels go in the right place, like Product, Reactant.
