Thinking Assault
No problem can stand the assault of sustained thinking.
Medical Schools Say No To Dissection
All of U.S. medical schools including Yale, Harvard, and Stanford don’t use animal dissection to teach medical students. The future doctors of America are using simulations, life-like models, and interactive computer programs to learn how to treat human patients. Y3K Tutor In Your Home maintains that there is a better alternative for every animal dissection assignment that any biology teacher might ask of a student.
Dangerous Dissection Chemical #3: Ethylene Glycol
Ethylene glycol–preserved specimens have actually been first fixed in formaldehyde or formalin solutions. They are then washed and preserved in ethylene glycol, which is the same chemical in your car’s antifreeze. Ethylene glycol is another toxic chemical that our children are being exposed to during biology animal dissections. It can affect the central nervous system, heart and kidneys. Remember that besides the toxic ethylene glycol, these animals still have formaldehyde inside them as well. When the animals are cut open, our children are exposed to toxic poisonous ethylene glycol and formaldehyde.
Dangerous Dissection Chemical #2: Alcohol
Another commonly used dissection preservative our children are exposed to is alcohol. This alcohol (usually isopropanol) is very flammable and should be avoided in the classroom.
Dangerous Dissection Chemical #1: Formaldehyde
After animals are killed specifically for classroom dissection purposes they are then often preserved. Dissection animals are embalmed with a chemical preservative called formaldehyde (also known as methanal). Formaldehyde is a nearly colorless and highly irritating gas with a sharp odor. The liquid these dissection animals are contained in is actually formaldehyde dissolved in water called formalin. Formaldehyde is a known nasal and dermal carcinogen. It is also a sensitizer, causing allergy-related symptoms.
When students cut open these preserved dead animals, formaldehyde can be released. This formaldehyde can damage the children’s eyes, cause asthma attacks and bronchitis when exposed to this poison. Symptoms of formaldehyde exposure include eye, nose, throat and skin irritation. Other dissection chemical symptoms include a persistent cough, other respiratory ailments, headache, nausea and dizziness.
According to the U.S. Environmental Protection Agency, this chemical preservative can be linked to cancer of the throat, lungs, and nasal passages. Children may be more susceptible to the respiratory effects of formaldehyde than adults, according to the Agency for Toxic Substances and Disease Registry (ATSDR). Biology students should not be exposed to dead animals preserved in formaldehyde.
Dissection Danger
Animals that are killed for middle and high school biology class dissections are soaked in toxic preservatives that are hazardous. In most cases, the commercial supply houses that process and ship these dead animals use dangerous formaldehyde, formalin, alcohol, or ethylene glycol to preserve the animals for our children to then handle. Over the next few days we will highlight some of the dangerous chemicals your child may be exposed to if they do animal dissections at school.
Dissection Physical Harm
Did you know that traditional middle school and high school biology animal dissections can do more harm than good for students? There are psychological, physical and environmental dangers associated with animal dissections putting your student at risk. Over the next several days we will take a closer look at the physical risks that may harm your student. Check back here tomorrow!

PARENTS AGREE: Y3K TUTOR IN YOUR HOME CHANGES LIVES #11
Innovative, determined to make improvements, professional, cooperative and most importantly very flexible with the many moods of our little man. We are very happy with the progress our son has made and continues to. Jerry is very responsive to parental feedback and questions. He tests new methods and adjusts them seamlessly. We highly recommend him to those looking for a serious tutor whose main goal is helping your child. Thank you Jerry for all your hard work!!
