Are double stuffed Oreos really double Stuffed?
This was the investigation we conducted to apply our knowledge of the properties of matter. Students used their knowledge of volume and mass to find out if in fact double stuffed Oreos were really double stuffed! Students used graduated cylinders, digital scales and formulas to find the mass and volume of the filling in each cookie and of course if they are really double stuffed the cookies should be double the mass and volume of the regular oreos and what the students found was that in fact double stuffed ore os are double stuffed and in most cases were a little more than double! Pretty cool! It was a great activity to apply what we have been covering in class and cookies are of course always a hit with the middle schoolers (not much of a surprise there!)
Later in the week we discussed density! I always love using this demo because it can lead to a great discussion about density and buoyancy! Students are always amazed by the fact that the regular coke sinks and the diet coke floats!
We wrapped up the week by performing a virtual lab on the school laptops where students identified objects as either going through a physical or chemical change! We will continue to look at properties of matter next week and have our assessment before moving on to states of matter and phase changes! Thanks for checking in!
