Monday, August 26

​

All classes should have at least 3 observations and a hypothesis for each

mystery box that was viewed on Friday.  Most classes need to complete 3 - 4

of the remaining mystery boxes.  All observations should be complete along with hypotheses by the end of the activity rotation.  I will want to stamp these on Tuesday when we complete the BIG REVEAL!

​

We are going to complete another activity before we return to our seats.  It is called the

"Scramble". 

Your lab group will try to assemble a meaningful sentence by successively turning over a set of word cards.  Each group will be given 24 cards.  Each card has one word on it.  Your group will place all 24 cards face down on your lab bench.  (DO NOT try to read each card when placing them face down.) The words on the cards form one long sentence that also tells a story.  The goal is to figure out the story by turning over the fewest cards.

 

After turning over 5 cards, students will hypothesize what they think the story is about on their "Scramble" worksheet hypothesis 1.

​

Students will then turn over 5 more cards and complete hypothesis 2 on the "Scramble" worksheet.

​

Students will then turn over 5 more cards and complete hypothesis 3 on the "Scramble" worksheet.

​

Finally, students will turn over the remainder of the cards, organize them into a meaningful sentence and write that sentence in hypothesis 4 on the "Scramble"

worksheet.  This will be due at the end of the hour.

 

FINALLY... Are you interested in an extra credit opportunity?  See me for details. Here's how these opportunities work.  You see me.  I give you the work and assign a due date.  I do not help you complete it NOR do the other teachers on staff.  It is typically higher level, advanced work.  You turn it in by the due date and receive extra credit for completing it accurately.  If you have to ask how many points you will earn...it probably isn't for you.

​

Tuesday 8/27/19

​

I will want to stamp your comp books with your 6 mystery box observations and

hypotheses.  This is an all or nothing event.  I expect all 6 to be completed.  If you missed a day, you need to get in here during activity period and get this made up.

After I stamp your books, it will be time for........drum roll.......THE BIG REVEAL!  How keen are your observation skills? 

​

I also want to discuss the "Word Scramble" activity from Monday.  Again, if you missed this it is necessary that you make it up during activity.  It is for a grade.  If you don't complete the work, you do not get the grade.

​

Then we will complete our first real lab, "Measuring Practice".  We will be using calcium chloride so you must tie back long hair, wear closed toe shoes, wear goggles, and wash your hands afterward.  The calcium chloride should not be disposed down the drain; it should be dumped in the dump cup (waste receptacle). The lab page will be due at the end of the hour.  You will be given plenty of time.  There will be no excuse for not completing each step.  Units are required for each measurement. 

 

On another note, I found it troubling that many of you reported that in 5th grade, students would consume particles of this on the playground.  I found this information on the internet:

Common Health Risks Associated With Calcium Chloride

According to West Liberty University, there are some risks to consider while handling calcium chloride. The substance can cause irritation of the skin and eyes if touched without proper gloves and handwashing. Long-term contact with calcium chloride can also lead to contact dermatitis, according to the International Programme on Chemical Safety (IPCS). If inhaled, calcium chloride can also cause irritation in the respiratory tract. If you experience irritation of the skin, eyes or respiratory tract, seek fresh air and wash the affected area.

Calcium chloride, while safe when ingested in doses applied to food, can be dangerous if consumed in larger quantities. Ingestion can cause nausea, vomiting or gastric distress. If a large amount of calcium chloride is consumed, drink several glasses of water or milk and seek medical attention as needed, according to the IPCS.

​

​

There will be a demo today.  The wave box. 

A write-up will be required in your comp book.  Describe the demonstration, what you see etc. 

Then give your best explanation as to why the colored water in the wave box behaved the way it did.

This will be due on Thursday.  IT MUST BE IN YOUR COMP BOOK!  A piece of notebook paper

will not a get a stamp. If you are absent watch the video below in order to complete the assignment.

​

There will be a worksheet on variables (independent and dependent) as well as controls.  It uses a SpongeBob / Bikini Bottoms theme.  It will be due on Thursday as well.

​

Thursday 8/29/19

​

Wave Box Demo write-up is due.  This must be in the composition notebook not on some scrap piece of paper or another notebook.

​

The SpongeBob IV/DV worksheet packet is due.  

​

There will be a packet on graphing for homework.  Graph paper will be provided.

It will be due on Friday.

​

Friday 8/30/19

​

Graphing packet is due.

 

Four Fluids Activity.  Your lab group will be given red, blue green and yellow salt water.  Each color of salt water has a different density because of the amount of salt added to the water. Your task is to determine the order of density from least to greatest using a straw.  I expect you will record how you determined the order in your comp book.   This will be due Tuesday.  

​

Here is a cool video on the properties of water

If you took the bonus work on sig figs, it is due today.
