Introduction

The Scientific Measurements data sheet is where you will place all the data from each activity in this unit.

Assignment Instructions

Step 1:

Download the Data Sheet for Unit 2 Scientific Measurements by clicking on the link below:

Step 2:

Reread the manual. Note there could be as many as three (3) types of experiment activities: Video Activities, Virtual Activities and Hands On Activities. The Scientific Measurements data sheet is where you will place all the data from each activity. Be sure to read the manual carefully as there may be requirements for photo or video documentation. Please consider that not all three types of activities will be present in all units.

• Video Activities In the video activities Dr. Betts is your lab partner. You should consider him to be your hands. You must write down the required data and do the necessary calculations.
• Virtual Activities The virtual activities are a simulated lab environment. You will be required to do experiments in this environment. You will need to write data and perform calculations on your Data Sheet.
• Hand On Activities These activities are designed to allow you to do actual chemistry experiments at home. Follow all safety precautions found in the manual. You must record all data, which may include photos or videos. Keep in mind all your photos or videos must be your own and must not be taken from the internet.

Step 3:

Convert your paper data sheet to .pdf. You may have been filling in your Data Sheet with a computer or tablet. If so all you need to do is convert your document to .pdf format. If you do not know how, check google.com. If you printed off your data sheet you will need to convert it to .pdf format. To do this use your smart device to make .pdf files of your Data Sheet. Apple iOS users can use the Notes app. Android users can download an app called Cam Scanner.

“Well-organized summary of analytical chemistry techniques including spectroscopy (UV, IR), chromatography (GC, HPLC), mass spectrometry and NMR. Ideal for students.”

Our teacher asked us to construct a periodic table for elements he’s come up with using Mendeleevs logic, and I have completed the descriptions of the elements– I just have no clue how I actually organise them into groups. To be more specific, there are eight groups that are used in Mendeleev’s periodic table, each group representing a different charge of valency (1+, 2+, 3+, 4 +/-, 3-, 2-, 1-, 0). The aim is to order these elements and then predict elements that have not been ‘discovered yet’ in this given set of new elements; and provide justification as to why this is so.*

I attached the resources we’ve been given, as well as the rubric and explanation to the assignment.

*for the justification segment, I don’t need fully written answers, just short explanations as to what should be written.
