Q: Should I wear safety equipment? Specimens contain trace amounts of preservation chemicals. To eliminate skin contact with these chemicals, wear nitrile or latex disposable gloves. Also, wear safety glasses or goggles, as liquids containing trace amounts of chemicals can occasionally squirt out during dissection. Find safety equipment here. Q: Do the specimens need refrigeration? How do I store them? The specimens are fully preserved and do not need refrigeration.
Q: How do I dispose of a dissected specimen? Seal the dissected specimen in a Ziploc bag and place it and the dissection tray in your regular outdoor trash container. Use disinfectant soap and water to thoroughly clean your dissection tools and the area where you worked. Seal the dissected specimen in a Ziploc bag to keep it from drying out.
If you want the specimen to stay fresh longer, use a heavy-duty plastic Ziploc bag, and add a bit of water or glycerin to keep it moist. Q: Do the dissection specimens smell bad? If you did dissections more than 10 years ago, you might remember the terrible formaldehyde smell of preserved specimens.
Things have improved since then! You will smell some of the natural odor of the specimen, such as a fishy smell with the perch or dogfish. Because specimens have been originally fixed in formaldehyde and a trace may remain, students should wear latex or nitrile disposable gloves and eye protection during dissections. Q: Are dissections hard to do? Dissections vary in the amount of time each takes, as well as complexity.
Generally, a student in junior high or high school will be able to dissect any specimen we offer. Elementary students do well with an owl pellet, earthworm, or cow eye.
Frogs and snakes are slightly more complex. Plan to allow about minutes for a simple dissection and minutes for larger specimens with more complicated anatomy, such as a shark or fetal pig. Allow more time for in-depth dissections that identify major muscle systems or trace the circulatory system. Usually, all that is required is to identify the major organs. Q: How do I store vacuum packed specimens sold in large quantities?
We sell our quantity discount specimens in a pack. Home Science Tools offers a wide variety of biology products and kits. But, we can help. Is STEM just another fad? Or are STEM fields the key that can unlock the future for not only young people but for the world?
Let's dive in. Science can be split up into several fields of study. However, we do many events that are open to the public that may meet your needs. Check out Upcoming Events to get an idea of current availability. We really mean tailored learning for ALL ages, from 5 to , we can adapt any workshop to engage every age group. For example, slide viewers can be used for younger children who cannot handle a microscope. We can perform dissections and involve younger children as each area of the specimen is explored.
The possibilities are endless. Absolutely, as long as it is related to the biological sciences, medicine, forensics, or any of the other topics outlined in the suggested Presentation Topics.
We tailor each of our programs to meet the unique needs of each group. I have traveled all across the United States to speak and conduct labs and other hands-on workshops. There are many ways to save on costs by having materials and specimens shipped directly to your location ahead of time, so please contact us so we can tailor a solution that will work for your group. Labs last from one to three hours. We also do lab workshops at camp locations that can last a full day hours.
We are always available to answer questions at the end of any presentation. We also require at least 90 minutes prior to the start time to get set up and 60 minutes to clean up at the end of class. For labs, groups range in size from 10 up to about 50 students. For lectures, group sizes much larger can work well depending on the audience, venue, and type of AV equipment available.
It depends on number of students per specimen, duration, location, and many other things that are tailored to the class. Contact Us for a formal quote.
