This unit focuses on 3 of the 5 major sacrifices offered on the Old Testament. They are known as the "sweet savor" sacrifices.
1) The whole burnt offering--emphasizes Christ's offering of Himself, without blemish, in complete obedience to the will of God the Father.
2)The meal offering (meat/food) emphasizes the balance, fragrance, and purity of Christ's life.
3) The peace offering is symbolic of the reconciliation that was accomplished on the Cross by our Lord and Savior--Jesus Christ.

Unlike the other 2 sacrifices, these 3 were voluntary gifts to God.

Your Gross and Cool Body - Sense of Smell

What are smells?

Odor and fragrance falls under the Science of Chemistry. Odors are molecules of chemicals from almost anything. They are transmitted through the air. Most odors are created by a mixture of different molecules.

What is the process of "smelling"?

We smell with our nose. :o) When we inhale air, it goes into our nose and is instantly filtered by tiny hairs on the inside walls of each nostril. Further back in our nose is wet mucus that is warmed by blood vessels just below the surface. Also, there are small hair-like structures, called cilia, that work like a broom sweeping the mucus further and further back. Eventually, the air passage opens up into the nasal cavity. In the normal course of all that air bouncing around, we swallow the mucus that was carried away with it. (Gross but we don't usually notice it.) Unlike everything else you inhaled, odor chemicals float upward, not downward. They actually go until they hit the top of the nasal cavity. Up there are "a gazillion" microscopic nerve cells that detect smells. The nerve cells are "protected" by a very thick mucus. Odor chemicals must penetrate the mucus to get to the very tops of the nerve cells. The really fascinating thing--praise be to God NOT Darwin--is that each nerve cell is shaped differently and designed to recognize different smells. Each odor molecule fits into a nerve cell perfectly. These cells send a message via the olfactory nerve to the smells department of your brain. It, tells you what smell or combination of smells you are smelling. Now, whether or not something smells good or bad is totally dependent upon you and your own sense of smell.

Experiment--Selective Smelling
This experiment comes from KRAMPF's Experiment of the Week.

"This week's experiment comes from my experience at the hotel in Minneapolis. They did not have any non-smoking rooms available, and the combination of smells from cigarette smoke and room deodorizer was quite strong when I entered the room. After a minute or so, I forgot about it, until I went out to the car. Coming back into the room, I was again struck by the smell. This reminded me of an experiment I had done years ago, showing how your nose can be very selective with smells.
You will need:
your nose
some vanilla extract
other things that smell
paper towel or a cotton swab

Be very careful about smelling other things, as many cleaners and other chemicals can irritate your nose or even be poisonous. Read any warnings on the label before smelling them.

Put some vanilla extract onto a small piece of paper towel. Hold this just under your nose and smell it. The smell is pleasant and quite strong. Hold the paper towel there and continue to breath
through your nose. You will notice that after a few breaths, the smell of the vanilla begins to get fainter. After several minutes, you will hardly smell it at all. Has your nose stopped working? To find out, keep the vanilla under your nose and bring another smelly substance (I used lemon juice) to your nose. You will smell the new smell just
as strongly as if the vanilla was not there, but the vanilla will still be very faint.

Keep both smells by your nose and soon they will both seem to fade away. Now, remove the vanilla, leaving the second smell in place. After a few minutes, bring the vanilla back and you will again smell it.

This ability of your nose to screen out smells is very useful. It can keep one constant smell from overpowering other smells. This is very useful to animals that need to smell food and predators over all of the other smells in their area. The next time you are expecting visitors, go outside for a few minutes to "clean your nose", to be sure that there are no leftover cooking smells in your house that you have gotten used to.
Your nose will cancel out some smells faster than others. Try different things from your refrigerator to see which ones last the longest. Be very careful about smelling other things, as many cleaners and other chemicals can irritate your nose or even be
poisonous. Read any warnings on the label before smelling them.


Aroma = pleasant smell or fragrance
Therapy = treatment or healing
Aromatherapy = healing through fragrance.

Basically, aromatherapy is the age-old practice of of using concentrated fragrances to soothe, relax, stimulate and balance emotions. When practiced by a trained aromatherapy practitioner, aromatherapy can supposedly (yes, I'm a skeptic) make a healing contribution to overall physical well-being.
NOTE!!! aromatherapy IS NOT a substitute for medical care! Never attempt to treat and illness, injury, medical problem, or skin condition with aromatherapy until you have FIRST sought help from a qualified medical professional.

Recent studies have reported the following information.

Peppermint and/or Lily of the Valley is a mental stimulant and may be beneficial to long distance drivers and students taking long exams.
Lemon is also a mental stimulant and has been shown to reduce errors in the workplace.
Vanilla is a relaxant and can be used for stress reduction. Often used with MRI patients to eliminate fear.
Fir is a relaxant and is used to reduce stress from the pressures of the day.
Lavender is a relaxant and has been shown to reduce headache pain and calm panic attacks. Also helps calm breathing during a cold.

Other Fragrances

Rose Geranium--renewing
Patchouli--feelings of peacefulness


1) THE SMELLY BOOK by Babette Cole
3) THE OLD MAN WHO LOVED CHEESE by Garrison Keilor
4) THE NOSE BOOK by Al Perkins

The following books are by Dorling-Kindersley, Inc and/or Dorling-Kindersley Family Learning. 

5) various American Horticultural Society Guides to planting different types of gardens.

NOTE** The following "recipes" call for essential oils. Use them with caution as some of them can "burn" the skin when in its "pure" form.


You will need:
Sweet Almond oil
essential oils
small containers (I found pretty ones at the dollar store)
small dried flowers (optional)

1) If you are using flowers, drop a few of them into your container and cover with a few drops of almond oil. Use a stick or straw to press the flowers to the bottom of the container. (They will absorb some of the oil so they don't float when you fill the containers.)
2) Using a dropper, put 15 drops of essential oil for every 2 oz. of bottle. (So a 2 oz bottle will use 15 drops, a 4 oz will use 30 and so on.)
3) Fill the remainder of the container with sweet almond oil.
4) Put on the cap and shake to blend oils.
5) NOTE: If you are using a bottle with a cork top, be sure to leave space between the cork and the oil so the cork doesn't swell from soaking up the oil.
6) NOTE: If capping with a cork, put a "professional" seal on your "product" by dipping the cork and neck of the bottle in melted beeswax.

Crème Perfumes and/or Lip balms

You will need:
sweet almond oil
essential oils (lime, lemon, etc for lip balm)
small containers with lids (anything from a decorative soapstone box to "cleaned out" Carmex container)

1) Prepare an oil and beeswax base. (This works best using a clean can that you can squeeze to form a pour spout at the top)
2) Put 2 oz of almond oil and 1 ounce of beeswax into the can.
3) Fill a saucepan with a couple of inches of water and set the can of oil and wax into the water. (Great science note: If the can bobs around, dump out some of the water until the can will sit in there without tipping over.)
4) Let the water in the saucepan just start to boil and turn down the heat. Stir the mixture in the can until the beeswax is melted.
5) Put essential oil(s) into a small decorative container. Use about 5-8 drops for lip balm and 8-15 for crème perfume. (Depends on the size and the fragrance you've selected. Also, if you are blending fragrances.--This is NOT an exact science so don't sweat it.)
6) Slowly pour the oil/wax mixture into the container on top of the essential oil.
7) Let it harden completely before putting on the lid. (Takes about 1/2 hour at room temp.)

Body Mist 
(or splash--depending on your container)

You will need:
essential oils
spring water or distilled water
small bottles (preferably glass) with spray tops or you can use it like a body splash.

1) Put essential oil(s) into the bottle--about 15 drops of a single oil or combination of oils.
2) Fill with water leaving a little space at the top--especially if you have a spray top.
3) Shake the mixture gently each time you want to use it.
4) Spray or splash.

Scented bath crystals

You will need:
Rock salt or coarse sea salt crystals
essential oils
decorative plastic or glass "jars" with lids
glycerin (optional)
food coloring (optional)
NOTE: The glycerin and food coloring go together to make colored crystals. You have to use each of them or neither of them.
Also, for coloring crystals, you will need several disposable plastic containers or bowls made of glass or metal.

To color your crystals: (Adjust the amount depending on the size of your "jars")

For approx. 1/2 cup.....
1) Measure 1/2 c. salt crystals into your "mixing" bowl.
2) Put 6 drops of glycerin into a metal spoon
3) Put one or two drops of food coloring into the spoon with the glycerin.
4) Without spilling (I had to say that) carefully stir the mixture with a toothpick while it is still in the spoon.
5) Quickly stir the contents of the spoon into the salt. Mix until evenly colored or just mix it partially for a "marbled" look.
6) Keep your crystals in the mixing container until they have been scented.

To scent the crystals.......
1) If you don't use colored crystals, just measure 1/2 cup of coarse sea salt or rock salt into a glass bowl or disposable container.
2) Drop 10 drops (per 1/2 cup) of essential oil or a 10 drop blend of oils into a metal spoon.
3) Put oils into salt and stir with the spoon to blend thoroughly.
4) Put the crystals into the decorative container and seal.

Soap making

Scented Candles

You will need:
Beeswax or paraffin wax.
essential oils (or candle fragrance available at craft stores)
clean tin can
pot of boiling water
wick (available at craft stores)
wax crayons (optional)

1) For poured candles, you will need a glass container (like those inexpensive votive holders) or a clean frozen juice container or milk carton--be creative)
2) Put wax in tin can and place tin can on stove in a pot of simmering water.
3) To color your candle, toss in a piece of wax crayon.
4) stir with a wooden stir stick until melted and color has blended with the wax.
5) stir in your essential oil or candle fragrance
6) Tie a length of wick to a pencil and lay it across the top of your decorative container or candle form.
7) Pour wax mixture into the container--keeping the wick down.
8) Put in fridge or freezer to set.
9) Leave in decorative container or tear away the "candle form" and use as desired.
