In the Classroom

Unlike the rest of your skin, your lips don’t produce oils to protect themselves. Because your lips don’t have protective oils, it’s easy for them to dry out in hot or cold weather and become chapped.

Activity Title

Make Your Own Lip Balm

 

Materials:

2 Tablespoons of Beeswax

2 Tablespoons of Honey

2 Tablespoons of Almond Oil

½ Teaspoon of Essential Oil (citrus, lavender, peppermint)

.75 oz container

1 Microwave Safe Container

Heat Source, Microwave

1 Wooden Stirrer

Pair of gloves

 

Procedure:

  1. Melt the beeswax, honey and almond oil in a microwave safe container for 10 seconds or less because it will burn easily if not taken proper precaution.
  2. Stir ingredients together using wood stirrer and mix.
  3. Stir in essential oil and mix.
  4. Pour mixture into container and let it cool before placing lid on top of jar careful with contamination.

 

Questions

What factors do you believe are important in being able to make lip balm in this activity? How could you design an experiment to test whether a factor that you identified were important or not and how changing it affects the activity?

What do all the ingredients do?

What are the important components of a lip balm? How could you design an experiment that would test whether an ingredient was important or not?

What are the properties of the components? Are they solids, liquids, or gases?

 

Explanation

Beeswax thickens the lip balm and helps the other ingredients to stick together. Almond oil is an emollient, which means that it softens and moisturizes your skin. Honey tastes nice and is also an emollient. Essential oils flavor your lip balm and make it smell nice.

There are many ways you can make alterations and customizations of a mixture of ingredients, or a formula, for making your own lip balm. What and how much of each ingredient that goes into each formula is used to essentially change the consistency, scent, flavor, and texture.

The basic ingredients for this experiment are a combination of solids and liquids. It forms a soft solid finishing product.
