• metal

• ionic

• covalent

• polar

​Bonding speed dating activity

• ​Each of you will be assigned an element to use for your "dating profile"

• Yellow elements should be seated by a yellow post-it and will remain seated throughout the activity

• Blue elements will rotate around the room.​

• You will have approximately 1 minute with each partner, when the timer goes off you will​ rotate to the NEXT yellow post-it in sequential order. #1 rotates to #2 and so on, until you return to your original "date"

• #12 will rotate to #1

• ​Now let's look at page 1 in your packet

​

​If you have a yellow element card, you should be at a seat with a yellow post it

If you have a blue element card, ​when the timer goes off, you will rotate to the next numbered yellow post-it, until you reach your first partner.

Let's go!​

Who was your ideal match?

​Take a few minutes to quietly review your compatibility profiles and determine who in the class you may be a match with, who was your BEST match, and why.
