Density: 0.534 g/cm ³
Stable Boron:
Protons: 5
Neutrons: 5
Electrons: 5

2. Density defines how compact a substance is using the measurements mass and volume.
Density equation: density=mass/volume
3. The activity that I chose was Density-MS by Tamara Sneed it required me to open the density simulator and complete each of the sub-simulation in the tab in the upper right hand corner. The tables below will show the data that I found. I will not bother doing the the Mystery application seeing as though it is required for the following question. The simulations that will be complete include Same Mass, Same Volume and Same Density.
Same Mass
Same Volume
Same Density

5. Science Standards
- C.4.5 Use data they have collected to develop explanations
and answer questions generated by investigations
- C.4.6 Communicate the results of their investigations in
ways their audiences will understand by using charts, graphs, drawings, written
descriptions, and various other means, to display their answers
- D.4.1 Understand that objects are made of more than one
substance, by observing, describing, and measuring the properties of earth
materials, including properties of size, weight, shape, color, temperature, and
the ability to react with other substances.
- D.4.2 Group and/or classify objects and substances based on
the properties of earth materials.
- D.4.6 Observe and describe physical events in objects at
rest or in motion.
You and I chose the same activity to complete! I really enjoyed the Density-MS activity because it was interesting to see how volume and mass together affect whether an object floats or sinks. I really like the charts you made to go along with the activity because they are easy to read and understand. Also, great job on finding science standards that actually go along with the activity you completed! It was interesting to compare the standards you chose with the ones I chose.
ReplyDeleteAs teachers it is important that we create purposeful lessons and activities that help our students learn. The activity that you did, and the different one that I did really hit on some standards that are important for children to grasp. Nice job matching standards to your activities! It is good to get practice like this now so that it becomes second nature to us when we have our own classrooms.
