Science Sunday - Sugar Race

I posted a bit late, but better late then never. 

 We learned about surface area with sugar cubes in water.

 One cube Austyn crushed with a hammer inside a paper towel and the other one Zoe left whole.

 They each put their cube in the water and lightly stirred the top to see which one dissolved first. Of course they needed to taste test the sugar cubes to be sure they were real.

 After getting the results we discussed why this would happen. I used the iPad to draw the image of a cube broken up and one still square and talked about how surface area is larger when something is broken up and how it would make it dissolve sooner. We also compared it to snow and ice melting since we've played with snow and ice many times. This activity was taken from the book Science Projects and Activities by Peter Rillero, Ph.D.

 Of course we need to pull out the baking soda and vinegar for extra fun, again.

I left the room for a few minutes and told them to not make too much of a mess and when I came back the ice cubes and the apple juice were on the table as well. It's funny how one activity turns into many.

Looks fun! I checked (online) my library for a copy of that science book and it has it. I am going to order it.

Same thing happens to me, I leave the room and one activity turns into ten.

And of course you have to taste test, how else can you warn them if it's poisoned?

Thanks for linking up!
