I hope you’re having a good vacation – you've earned it!
You might have received an amazon.com gift card or other monies for the holidays – you can use some of it to purchase the lab book Chemistry on a Budget.
This book contains inexpensive chemistry labs to expand your repertoire. You can buy this lab book for $23 at amazon.com or lulu.com.
There are two versions of each lab, one with a ten-question conclusion and one with directions for a full lab report. This way the teacher has the option! Each lab is two pages to allow for one two-sided handout.
It will take a week or so to get to you, so Order Now!
*Some of you have purchased my lab book – be sure to check out Page 141 !

As you discuss the elements of The Periodic Table, various health benefits or concerns can be topics of discussion. Recently, there was a report on National Public Radio about iron supplements and the development of the “Lucky Iron Fish” :
According to the American Society of Hematology:
“Iron [Fe] is very important in maintaining many body functions, including the production of hemoglobin, the molecule in your blood that carries oxygen. Iron is also necessary to maintain healthy cells, skin, hair, and nails.
Iron from the food you eat is absorbed into the body by the cells that line the gastrointestinal tract; the body only absorbs a small fraction of the iron you ingest. The iron is then released into the blood stream, where a protein called transferrin attaches to it and delivers the iron to the liver. Iron is stored in the liver as ferritin and released as needed to make new red blood cells in the bone marrow. When red blood cells are no longer able to function (after about 120 days in circulation), they are re-absorbed by the spleen. Iron from these old cells can also be recycled by the body.”
According this this site:
“Iron deficiency is very common, especially among women and in people who have a diet that is low in iron.”
Here is a 7-minute YouTube talk by Gavin Armstrong, the inventor of the “Lucky Iron Fish” :
“Foods rich in iron include:
- Red meat
- Dark green leafy vegetables, such as spinach
- Dried fruit, such as raisins and apricots
- Iron-fortified cereals, breads and pastas
Many foods are supplemented with iron to avoid anemia. These include Iron-fortified cereals, breads and pastas.
Here is a 6 ½ minute video showing a magnet removing the iron in breakfast cereal:
Here is a Scientific American article describing an experiment showing the iron in cereal:
This lab doesn’t use a blender but a plastic bag.
You might want to complete this as a demonstration instead of a class lab. I’d love to hear how it works in your classroom!
