Mystery Canisters

Alright, so once we figured out what the above picture was of, we actually did an activity called mystery canisters.  The activity allowed students to alter the contents of their film canisters and make them sink, float and suspend.  From the activity, they should see the relationship between mass and volume as well as density and it's role as far as buoyancy.  Fun times in science class!

Density Activity

Density Activity

Today in class, we worked on calculating density of various regular shaped objects made of wood.  Students were to calculate the volume and mass.  From those two measurements, they would be able to calculate mass. 

Once done completing the densities, students are to order the densities from smallest to largest.(math skills)  The worksheet is below, although all the wood is in my classroom!

Conclusion Quiz Today!

Quiz Over Conclusion Writing

We took a quiz over how to interpret data and write a conclusion properly.  Students are expected to "master" this concept by scoring a 25 or greater out of 28 on the quiz.  If they don't master the quiz, they will take it again until they do.  Conclusion writing is on the MSP test this spring.  After the quiz, we worked on calculating mass of various objects in the classroom and gaining some perspective on what a gram really is.  

Have a great weekend and if you can bring in gummy bears next week for a lab, that'd be great!
