The Great Cornstarch Explosion!

Annabel Baldwin wrote up our Cornstarch Explosion Lab from yesterday:

 

step 1 question: what will happen when cornstarch is mixed with fire?

step 2 hypothesis: I think that when cornstarch mixes with fire that the flame will get larger.

step 4 plan: to do this experiment we will need to blow cornstarch intoa propane torch and see what will happen. we will need a lighter, a propane torch, cornstarch, gloves, safety goggles,fire extinguisher, and a piece of paper.

step 5 analyze: the results of the experiment are that the cornstarch only reacts when blown into the fire. Why does that happen? Well, if you blow the cornstarch into the air there is oxygen with the cornstarch and oxygen is needed for fire. And yes my hypothesis was corrrect because the cornstarch made the fire expand.

 

Unfortunately, our magnificent photographer neglected to take a picture of the explosion :(

 
We had garden class again yesterday! The kids cleaned and peeled garlic to bring over to Chuck in the cafeteria,
 
 
made beet salad,
 
 
and repotted plants
 
 
 
Today there were some construction issues so we had whole group reading and social studies class outside. It was a beautiful day for it!
 
Many of the students were delighted to see Miss Dawn back at the school today.
We are reading a story in whole group reading called "Pipiolo and the Roof Dogs", about small dogs who live on the roof. I brought in a photo of my own small dogs, Olive and Jo, to show the class. I have asked them to please bring in photos of their own dogs tomorrow to share with the class.

 

Here are today's assignments.
 
I hope everyone is having a great week!
