Lithium: 3 Protons, 3 Neutrons, Density-- 0.53 g/cm3
Boron: 5 Protons, 6 Neutrons, Density-- 2.34 g/cm3
2. Define density and the equation for density and post on your blog.
There are several definitions for density. The most appropriate one that I found was mass per unit volume. Density's equation is mass/volume.
3. Run the Density simulation http://phet.colorado.edu/en/simulation/density and complete one(your choice) of the prepared Teaching Ideas and post your results on your blog. The activity you choose should be one of the student intended activities.
There are many science standards that could be met through these activities. Completing simple tasks and learning how to incorporate technology into the science world is a big idea that is associated with this site. When somone is learning and having fun at the same time, it is easier to comprehend information in the future. This way it is not forced into someone's head. Children can do it at their own pace and to their own liking.
Floating and Sinking:
Pre Lab Questions:
Pre Lab Questions:
What could it be made of?
It could be made of wood, plastic, styrofaom, or ice
What do you think will happen if you make a bigger block out of the same material? Will it float or sink?
It will float
You have another block that sinks.
What could it be made of?
Brick, aluminum, or some type of metal
What do you think will happen if you make a smaller block out of the same material? Will it float or sink?
It will sink.
Why do you think Block #1 floats and Block #2 sinks?
They are made out of different materials. Block number one has less mass and less density than block number two.
4. Complete the Mystery Blocks activity on the Density simulation. Post on your blog the data you collected (mass, volume, and density) and the identification of the material and the known density.
Block A
Mass: 65.14 kg
Volume: 3.38 L
Density: m/V= 19.27 kg/L
Block B
Mass: 0.64 kg
Volume: 1.00 L
Density: m/V=0.64 kg/L
Block C
Mass: 4.08 kg
Volume: 5.83 L
Density: m/V=0.69 kg/L
Block D
Mass: 3.10 kg
Volume: 3.38 L
Density: m/V=0.92 kg/L
Block E
Mass: 3.53 kg
Volume: 1.00 L
Density: m/V= 3.53 kg/L
5. Identify and post on your blog the Science Standards that could be met through these activities completed in Activity 5
