Yesterday we learned about the process of performing a science experiment such as creating a hypothesis, identifying a procedure, identifying and explaining variables, performing the experiment, recording the results and stating a conclusion.
We used this process while doing an experiment with "Magic Rocks". The Magic Rocks are chunks of metal salts that have been stabilized by being dispersed in aluminum hydroxide. The magic solution is a solution of sodium silicate in water. The metal salts react with the sodium silicate to form the characteristic colored precipitant (chemical towers about 4" high).
Here are some pictures from our science experiment yesterday!
Today, I want you to go to the science station and look at our Magic Rocks. What do they look like today? How tall are they? Which one is the tallest? Do you think the color effects the rate that the rocks grow? Respond with your answers in the comment box below!
Today we have our field trip to the Pennsylvania Military Museum! What are you looking forward to the most?
the pink one is winng and its 4 and a half inches tal
ReplyDeleteGood job Brittany, the pink one was 4 1/2 inches! Do you think the color effects this or was it just chance the pink one was the tallest? How tall are the rest of them?
