Activity 5

Lithium:
3 Protons
3 Electrons
4 Neutrons
Density: .53

Boron:
5 Protons
6 Neutrons
5 Electrons
Density: 2.46

Density can be defined as the amount of matter in any given space. The equation for density is d=m/V.... or density=mass/volume of an object.

I ran the same density problem on the game and all of the objects floated.

For the Mystery game, A=65.14 kg and sunk, B was .64 kg and floated, C was 4.08 kg and floated, D was 3.1 kg and just barely floated, and finally E was 3.53 kg and sunk to the bottom. B was an apple, C was a diamond, D was aluminum, and E was a diamond.

Standards that could be met by accessing this site and going through these simulations are as follows...

A.4.3 When investigating a science-related problem, decide what data can be collected to determine the most useful explanations
A.4.4 When studying science-related problems, decide which of the science themes are important

A.8.3 Defend explanations and models by collecting and organizing evidence that supports them and critique explanations and models by collecting and organizing evidence that conflicts with them

A.8.6 Use models and explanations to predict actions and events in the natural world
A.12.1 Apply the underlying themes of science to develop defensible visions of the future
B.12.3 Relate the major themes of science to human progress in understanding science and the world
