The Physical and Metaphysical Properties of Fluorite

Fluorite is an isometric crystal composed of Calcium and Fluorine (CaF2). This mineral was first identified in 1529 and has been credited with having many healing properties. The name is derived from the Latin, fluere, meaning “to flow.” This is due to the relatively low melting point of 2557 degrees F. Fluorite is used in the steel production to decrease the viscosity of slags and eliminate impurities. It is also used in the manufacturing of some glassware and polymers and enameling cookware. Fluorite is found in many places including the U.K., Mexico, Morocco, Peru, Brazil and the U.S.

Physical Information

Color: white, green, purple, yellow, blue, gray

The color of the specimen is determined by impurities that have replaced calcium in the crystal structure and the presence of hydrocarbons (petroleum). Pure form is clear(white).

Hardness: 4

Class: Halides

Fluorescence: Many specimens are fluorescent under UV light.

The phenomenon of fluorescence received its name from this mineral.

Density/Molecular Weight: 3.18 g/cm3   /   78.07 g

Metaphysical

Fluorite is credited with having many spiritual and physical healing properties ranging from easing the pain of arthritis to reducing nervous energy. The healing properties are largely determined by the color of the specimen.

Green absorbs excess energy, allowing for information from the subconscious to be moved to the conscious mind. Helps egocentric problems and heals stomach and intestinal illness.

Purple stimulates wisdom and the ability to discriminate, allowing for the promotion of spiritual vision. Useful in healing issues related to bones, marrow, and the spine.

White brings spiritual and mental harmony. Brings peace and strengthens awareness. Aligns all of the Chakras.

Fundraising with Glitter Tattoos

Ordinary fundraisers just aren’t cutting it anymore. For high returns, you need something fun, exciting, and extraordinary: you need Glitter Tattoo Station by Glimmer Body Art.

Costing less than $1 each, these bright, bold tattoos come with high quality glue and last over a week. These Glimmer Tattoos are the premier glitter tattoos on the market. They are US dermatologist tested, hypoallergenic, and non-toxic.

Each kit comes with enough stencils to make 300 professional tattoos, but there is plenty of glue and glitter to make at least 1300 tattoos–just add more stencils!

When planning your next fundraiser, consider Glimmer Tattoos for high return and lots of fun.

They also come in smaller kits with enough supplies for 15 tattoos.

Teaching Chemical Changes in the Elementary Classroom

Sodium Bicarbonate, Calcium Chloride and Phenol Red

Let’s go over the procedure first and then we will discuss what is happening.

1. In a quart baggie, place sodium bicarbonate(1 tsp) in one corner and calcium chloride(1 tsp) in the other.
2. Lay the bag on its side and place a small cup (medicine cup size – 1 oz) of phenol red in center of the bag. Be careful not allow the any on the chemicals to mix yet. Seal the bag
3. Gently pour the phenol red where it spills into each corner. Do not mix the two corners yet.
4. Have the students feel each corner and make observations. Continue the observations for a few minutes.
5. Pick the bag up and gently move the bage side to side, mixing the chemicals. What happens?

Explanation

The side of the bag with calcium chloride becomes warm. The calcium chloride dissolves forming calcium and chloride ions. The release of heat (exothermic) is a result of the calcium chloride dissolving and not a chemical reaction.

When the sodium bicarbonate dissolves to form sodium, hydrogen and carbonate. It becomes cool (endothermic). The baking soda absorbs heat in order to dissolve. This is not a chemical change.

When the two sides are mixed, calcium carbonate is formed which is insoluble. Also formed are water and carbon dioxide. The carbon dioxide (gas) causes the bag to inflate. When the carbon dioxide dissolves in the liquid, carbonic acid is formed. This change in pH causes the phenol red to turn yellow. A chemical change has now occurred.

Remember to have the students use all lab safety measures. If the bag becomes over inflated, release some of the gas.

Teaching Wind Power

The interest in renewable energy has increased greatly. The US currently produces enough wind energy to power 14 million homes. Approximately 2% of our energy comes from wnd, which is double from just 3 years ago. many beleive that in 2030, 15-20% of our energy will come from wind.

The reason for the growth is partially associated with new government regulations concerning our impact on the environment. Federal and local governments are receiving pressure from voters to find alternative sources. Experts believe that if the 2030 scenerio occurs, we would reduce carbon dioxide emissions by 7600 metric tons and create 200,000 jobs.

Windmills have been around for centuries to pump water and grind seeds into grain. A wind turbine is an advancement that turns an electrical generator. The force of the wind, turns the blades. the rotor turns and spins a driveshaft that is connected to an generator. the generator converts this mechanical energy in to electrical energy.

There are several variables that determine the amount of energy produced: wind speed, diameter of the rotor, density of the air, and efficiency of the turbine.

A great product for teaching wind power concepts is the Basic Turbine. The Basic Turbine is a great start for teaching about wind energy in the classroom. Visit www.heathscientific.net to purchase this item. This is the most affordable and robust wind turbine kit on the market. Design blades and test your power output with a multimeter, LED bulbs, or an ultra capacitor.

The instructions that are included will show you how to build this PVC turbine, how to make blades for your wind turbine, how to use a multimeter to record electrical data and will discuss some basic wind energy science.

Fundraising for the Science Classroom

In School Science Store

With the reduction in state funds, the need to raise money through other methods has become even more important. Science is a subject that can’t be fully appreciated when limited to text books and worksheets. One of the keys to teaching young students is camoflage. When the student is engaged, enjoying the activity, creating and problem solving, they forget that they are supposed to be learning. These instances are where some of the greatest lessons are learned.

When approached properly, science is easy to make interesting……but it isn’t free. The students benefit greatly from using real science equipment, beakers….graduated cylinders…microscopes….live animals…pipets and test tubes. As educators, one goal should be to create young scientists and prepare them for the world they will find.

I often hear that “My school can’t afford these items.” With some hard work, outfitting a science lab can be achieved. Heath Scientific has been providing fundraising options to teachers, PTO’s and school organizations for 10 years. Create excitement and interest in your science program by setting up an Exploration Fair. Your school will ask volunteers (parents are great resources) to help run a retail store for a week. The store has science experiments, rocks, fossils and educational toys that excite the students and raise funds for your school.

Set up an online store at error and encourage students and parents to visit the site for birthday and christmas presents or for science fair projects. The items are shipped directly to the customer and you do not have to distribute any merchandise. Your organization receives a percentage of all sales.

Heath Scientific also provides bulk packages that allows your organization to make up to 80% profits. Use the profits earned to buy real science equipment that can be used for many years.

Don’t let money stop you from providing your students a top notch science classroom.
