Today in STEM we looked at the engineering design process and worked on finishing the plan stage.  We watched Mrs. Ganus make a low quality batch of play dough.  We then recorded her steps in a flow map.
We then brainstormed how to change the order of the process to make a higher quality play dough.  Here is our plan.
"We thought if we mixed the salt and water together first the salt would dissolve and the mixture would not be as grainy." Jude
Next we worked on if we were going to change the amounts of each material we added.  Every group decided this on their own.  Tomorrow we will follow our plan and hopefully make a higher quality play dough.
"Our group decided less salt because so it wouldn't be so gritty."Emma
"Our group decided less water because the first batch was too sticky."Riley
"Our group kept flour the same but added more water and less salt so it didn't feel like sand." Aidan
"Our group is going to add more flour and less water so it will not be so sticky."Alberto
"Our group decided keep the flour the same and lower the water and salt so it will not be so gritty and runny."Laura
