Activity 4: Density

1. Build a neutral lithium atom and a neutral boron atom. List the number of protons, neutrons, and electrons for each. Also look up and post the density for each of the elements of your blog.

Lithium

Neutral Lithium Atom: 3 Protons, 4 Neutrons, 3 Electrons

Density: .53 g/cm 

 

Boron

Neutral Boron Atom: 5 Protons, 6 Neutrons, 5 Electrons

Density: 2.34 g/cm



 

2. Define Density and write out its equation.

The quantity of mass per unit of volume. Mass/Volume (D = M/V)

 

3. Run the Density simulation and complete one of the study activity sheets.

 

 Below are pictures of my results from the Density worksheet by Tamera Sneed.

 

 

 

 

4. Complete the Mystery Blocks activity on the Density simulation.

 

A) Gold

Mass: 65.14kg

Volume: 3.38L

Density: 19.27

 

B) Apple

Mass: 0.64kg

Volume: 1L

Density: 0.64kg/L

 

C) Gasoline

Mass: 4.08kg

Volume: 5.83L

Density: 0.70kg/L

 

D) Ice

Mass: 3.10kg
Volume: 3.38L
Density: 0.92kg/L

 

E) Diamond

Mass: 3.53kg

Volume: 1L

Density: 3.53kg/L



5. Identify the Science Standards that could be met through these activities completed in Activity 5.

• Conduct Science investigations that encourage asking and answering of questions. (A.4.1)(ITL B.4.1)
• Determine relevant data to use when investigating a Science related problem. (A.4.3)      
• Note changes that are occurring or have occurred when studying a Science related problem. (A.4.5)
• Use data collected to create explanations. (C.4.5)
• Clearly be able to explain results of investigations. (C.4.6)
