Dangerous Dissection Chemical #1: Formaldehyde

By

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

By

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!

Fun Fall Fact

By

Yellow, orange and other variations are always in the pigment of tree leaves. They are overpowered by the abundance of green from the chlorophyll in the leaves. When the sun weakens in autumn and days grow shorter, the amount of chlorophyll in the leaves diminishes, allowing the other pigment colors to show through.

Back To School Success #2: Agenda Books

By

Agenda books are great for recording and keeping track of homework assignments. The best agenda books to use are the ones that have the date and each subject printed daily. Y3K Tutor In Your Home strongly suggests that you stay away from the planners without the date and subject names pre-printed in each box. We have observed that the unmarked agenda books cause many organizational problems for students. If the subject names are not pre-printed, the students tend to focus on writing the subject name when they should be listening and writing the assignment. Or if students don’t bother to write in the subject name, they sometimes are not sure which assignments are for which class after they have written them. When dates are not pre-printed, some students will write assignments on various pages and have them scattered throughout the book.
