I re-learned that oil is less dense than water. Oil floats on water. I definitely knew this, but while I made my predictions, I was not thinking that oil usually floats on top of water. 

The more dense a liquid is, the more likely something will float in it. Hence why more objects were able to float in the syrup. This makes sense to me, since syrup is a thicker texture as well.

I also learned that Just because something has a big mass, doesn't mean it is going to be a super dense object. Density = mass/volume.

I feel that I learned more by doing the experiment myself, in my kitchen, rather than on the density simulator via the internet. I was able to use concrete materials, the "real thing" (Eggen & Kauchak,2012, p.134) which helped me not only visualize what was going on but also gave me more opportunity for observations and comparisons between objects.

It allowed me, the student, to have "increased involvement" in the learning and  it made the content more memorable by being a hands-on experiment(Silver,Strong & Perini, 2007, p.21). 

This lesson also uses the guided discovery model by allowing the student to predict outcomes and determine why an object may sink or float. 

I obviously did not have a teacher stopping to ask questions along the way or a chart to fill in or anything, but I can definitely see this as being a great lesson to incorporate these strategies into. ]]> 2016-08-01 15:52:31 UTC https://padlet.com/asherwood/6xa23jrtpafm/wish/117304192 asherwood https://padlet.com/asherwood/6xa23jrtpafm/wish/117304619 Penny Prediction:

My Prediction: based on observations from experiment 1:
Least Dense- Vegetable Oil
Water-Middle
Most Dense-Breakfast Syrup

My prediction was CORRECT. 
Top to Bottom:
OIL
WATER
SYRUP]]> 2016-08-01 16:06:24 UTC https://padlet.com/asherwood/6xa23jrtpafm/wish/117304786
