Is Sodium good for you?

Kamusta! In Health today we learnt about Sodium, aka, salt. It's in almost everything. We need it to live a healthy life but at the same time eating too much of it can be unhealthy. Today, we had to rate 13 packaged foods depending on how much salt we think they have in them. Something interesting I learnt today was that 2 Minute Noodles actually don't have a lot of sodium included.

How, much sodium do you think a teenager should consume daily?

Did The Crystals Work?

                       Did the crystals work?

Crystal Type	Shape (Describe the shape)	Size (of individual crystals)	Hardness (Crumbly to Rock Hard)
Borax	Star shape (Because of pipe cleaner)	Medium size, not too big and not too small.	Crumby. If you touch it, it will crumble up.
Sugar	No Crystal Formed	No Crystal Formed	No Crystal Formed
Salt	I don't really know. Their really tiny.	5 mm wide	Hard

What crystals worked out best and why? Elisha Mae's crystal (Salt) worked out the best! Even though her crystals were formed on the stick and not the string.

After watching the videos as a class, explain how the following crystals are formed:

Type	Explanation
Salt	Salt crystals are made by sea water.  Then the salt water is put in the pond. When the sun comes out the water evaporates. Then you are left with salt. Evaporate meaning : Liquid turns into gas.
Sugar	Sugar Cane is cut up and rolled into a thin line. Then they get the sugar cane and heat it up. The mixture turns into a sugary syrup. That is called crystallisation. Now you have sweet and dry sugar.
Snowflakes	Little particles of dust fly through the air with the help of a cold breeze. As soon as a rain droplet touches them they began to form a hexagon shape. The hexagon shape forms branches. The branches become longer and pointier as it gets closer and closer to land.

                                   

CRYSTAL TYPES

AIM: TO LOOK AT THE 7 DIFFERENT TYPES OF CRYSTALS

Salt Crystals

Sugar Crystals

Borax Crystals

7 different crystal shapes

The 7 types of crystals

Type	Number of sides	2 examples	Image
Triclinic	7	Turquoise Rhodonite
Monoclinic	10	Coffin
Orthombic	6	Rectangle Log Closet
Trigonal	10	Diamond
Hexagonal	8	The shape on a football.
Cubic	6	Dice Ice Box Rubix Cube
Tetragonal	12	An antique lamp on a wall. Maybe near a park or old building.

Conclusion

My crystal didn't turn out too well to be honest. Finding the proper shapes was the hardest part of all. I personally wouldn't like doing more of this work in the future.
