science with dad

a week or two ago, ryan and two colleagues treated afton's class to a CSI science experiment.

 they used magnetic stirrers to pull iron out of cereal.

below you can see the bowls of cereal on the stir plates.

i thought this was really fantastic, because you can actually see little strands of iron when you remove the goopy cereal!

 they also had to see which powder and liquid produced a reaction.

 we also took a few pictures with friends.

(not part of the experiment!)

below is the last station where they tested pH strips.

the kids were trying to determine who left the mess on the kitchen table that morning. 

below are the suspects and their recorded observations.

you'll notice that i am one of the suspects. 

i was guessing that ella left the mess. 

turns out that you can't trust science, because the conclusion was that mom left the mess.

everyone knows that would never happen!
