Lessons in Life Cycles – Chicken Embryology

What came first – The Chicken or the Egg?  Here is your chance to finally figure that out by exploring the life cycle of a chicken!  We are excited to offer three easy to use chicken incubators and full student lesson plans that provide hands on learning about life cycles and chicken raising.  Expand on these materials by diving into topics such as other organism life cycles, agriculture/industry, and careers in Ag!

Loan Kit Cost: $20.00 for incubator, brooder, and hatching supplies* for 1 month. Fertilized eggs not provided!

*Embryology Kit is available to School’s/Non-profits at no cost. Fertilized eggs might be provided depending on availability of local suppliers.  Recommendations are available for venders of fertilized eggs.

STEMin @Home Activities – Easy Experiments you can do from home!

In the summer of 2020, we came up with STEM activities and videos youth could watch and participate in at home.  Check out these fun, random, but thrilling activities we came up with to keep us STEMin during COVID! Check out our YouTube page for walk through videos that demo these and other fun projects!

ViralCycles – A Study of Viruses!

With recent events, our STEM team thought it might be useful to have a series of lessons devoted to youth learning about viruses and how a single virus can cause so much upheaval.  This 6 lesson series was developed by Dr. Barbara Shaw with Colorado State University and discusses everything from size, infections rates, and personal protection.  Use the videos to help youth walk through the lessons and learn how to stay safe and healthy!

  1. Video: Safety – Keep Yourself Safe!
  2. Video: Models’ – What is a Virus?
  3. Video: Shapes – What Does a Virus Look Like?
  4. Video: Sizes – How Big/Small is a Virus?
  5. Video: Doubling – Part 1 & Part 2
  6. Video: Contagious! – Part 1 & Part 2

Still Need More STEM Ideas?

We are always on the lookout for interesting STEM (or STEAM!) themed lessons!  See our listing below of short, easy to follow lessons that we have incorporated into youth learning!
