The number of electrons for the element of lithium is 3. The number of protons is 3 and the number of neutrons is 3. The density of Lithium is .53 g/cm.
What is Density?
Density is the quantity of mass per unit volume.
Equation for Density:
Density = Mass/Volume (D = M/V)
I did the simulation on density where it dealt with different types of objects and you would put them in the water tank to see if they float or not as well as the mass of them and their volume. You could also change the size of the objects to make them bigger and make them weigh more also. What I found interesting was that generally no matter how much the objects weighed or how big you made them, it would still either float or sink.
In the mystery block simulation there were 5 different blocks that we each of different size and weight.
The yellow block (A) had a mass of: 65.14kg
Volume: 103.38L
Density: .6204
Identification of block: Aluminum
The blue block (B) had a mass of: .64 kg
Volume: 100.64L
Density: .0063593
Identification of Block: Ice
The green block (C) had a mass of: 4.08kg
Volume: 104.08
Density: .0392
Identification of Block: Wood
The red block (D) had a mass of: 3.10 kg
Volume: 103.10L
Density: .0300679
Identification of Block: Ice
The purple block (E) had a mass of: 3.53 kg
Volume: 101.10L
Density: .0349
Identification of Block: Brick
The science standards that could be met through these simulations and activities are:
*Evaluating a product to get an answer (Using Mass/Volume to get Density)
* Understand and identify objects (using what we knew about mass and volume to identify the object)
* Knowing properties of objects and materials.
* Properties and changes of properties in matter.

I like how when you posted your standards you also wrote where it specifically connected to the assignment. Great habit for a teacher to do. These activities are very helpful for learning through a more hands-on visual approach which many student need especially with Chemistry.
ReplyDeleteI would have to agree with Alyssa, explaining where they connect to the assignment is a great thing to do. Sometimes standards like the science ones, can be difficult to understand and can be a lot to take in at one time but explaining how they relate to an assignment is really helpful. It kind of breaks them up and makes them easier to understand and use. Awesome idea!
ReplyDeleteI really like the simulation you chose to complete. I actually did the same one! I thought the simulation was really interesting and it was cool to see how changing the volume of an object cause it to sink or float. Also, great job on your standards! It was helpful that you listed how each standard fit specifically with the simulation you did. It also shows that you fully understand what the standard is saying. Great job formatting your post and keeping it organized!
