The first topic that we will be covering in our Winter Camp is chromatography. We will perform paper chromatography using washable markers, and turn it into a set of flowers! It is important to note that this craft does have some drying time. We will discuss all things chromatography, by covering what it is, what it is used for, the different types of chromatography, who performs it, and how to conduct it. This activity is recommended for children aged between 4 to 10, however, all ages are welcome!
MATERIALS NEEDED:
- 3-4 paper towels or coffee filters
- Washable markers - 1-2 straws - 1 disposable cup filled with water - Tape HOW TO
Step 1: Cut out a 4 inch by 4 inch square of paper towel or coffee filter.
Step 2: Using washable markers, draw a circle in the middle of the square. You can use as little or are many colors as desired. Step 3: Fold the square in half, and in half again. The color should be in one corner. Step 4: Dip the paper towel or coffee filter into the water, but do not let the water touch the colored portion, just under it. Let the water spread the colors to the top. Step 5: Unfold your paper towel or coffee filter and place it onto a paper towel to dry. Step 6: Once dried, fold it in half, and tape half of a straw to the middle, which will act as the stem to your flower. Step 7: Bring both sides of the paper towel or coffee filter together, creating a circle around the straw. Step 8: Adjust the sheets of the paper towel or coffee filter to look more like a flower. THE LESSON
In this session, we will explore the various aspects of chromatography, including Liquid Chromatography, Gas Chromatography, Thin-Layer Chromatography and Paper Chromatography. For each type of chromatography, we will review what it is, what it is used for, and how it is performed. The kids will have the opportunity to create Paper Chromatography, and see the mixture of inks in their washable markers. They will be able to get a true hands-on experience, and be able to compare their results to those of others in class. This will reinforce all of the information they have learned, enhance critical thinking skills, and push creative boundaries.
