In a previous post on warblettes, we conducted a small experiment demonstrating the absorption characteristics of warblettes. There is a small summary below that you can use as a refresher, or you can view the actual warblette experiment.
Warblettes Lab Activity
As mentioned in the previous post, warblettes are co-polymers that absorb up to 200 times their volume in water. Warblettes are perfect for science fair experiments, in the classroom, or just as a fun activity for your family. Warblettes, which are sometimes referred to as water marbles, are non-toxic and come in clear, red, blue, green, and yellow colors.
The basic absorption experiment we posted on warblette absorption is a simple experiment that uses household objects. Warblettes can be used for much deeper science and educational learning. Heath Scientific has created a lab manual for this purpose.
The warblette lab activity book has activities for every age student. There are 13 activities ranging from math and graphing to cellular biology. You can use warblettes to demonstrate potential and kinetic energy, change over time (graphing), man-made and natural polymers, and light refraction. The labs include explanations and procedures. If needed, modify the activities to fit your students abilities or needs.
The Labs Cover:
1.) Calculating Volume – Math
2.) Observation Skills
3.) Polymers and Water Absorbtion
4.) Absorption of Household Liquids
5.) Water Absorption and Time
6.) Water Absorption and Temperature
7.) Advanced Measurement – Volume, Calipers, Averaging, and Reading Charts
8.) Graphing – Line Graph
9.) Potential Energy – Comparing Diameter to Rolling Distance
10.) Varying the Height of an Inclined Plane
11.) The Effects of Acidity on Water Absorbtion
12.) Light Refraction
Both the warblettes and the lab activity book are available at Heath Scientific, which has been providing educational supplies for over 20 years.
