Re: Turn Milk into Plastic

Hello saritachopra, This is an interesting project and you are asking good questions. Did your son repeat the experiment 3 or more times as suggested? If he has 3 observations (replicates) for each of the 4 recipes, then he could see if the "best" recipe was best for each of the 3 replicat...

Re: crack2.py freezing on method 2

Hello, I will use the modified version of crack.py that you linked when referring to code in my post. I will first answer how num_pass_wheels in determined. If you look at the function 'signature' for the method 2, you can see it is “def search_method_2(num_pass_wheels)”. This means that num_pass_wh...

Re: Tsunami project - data graphing help please!

Hello IrishLake, Here's one suggestion for making a graph to show all of the data as your daughter suggests: You could put water depth AND trial number on the x-axis and wave velocity on the y -axis. To do this, there would be 3 groups of 3 water depths for 9 sets: _ _ _ _ _ _ _ _ _ depth 1 depth 2 ...
