Friendly Biology is chock-full of meaningful, safe, hands-on labs which create a multi sensory experience for the learner. The labs are tightly correlated with the concept being presented in the lesson. Most of the materials and equipment needed to conduct the lab are found around the house or can be readily purchased at the local grocery store or hardware store.
Labs found in Friendly Biology include:
Growing a Pet Potato Plant
In Quest of Carbon: Marshmallow Incineration
Testing for the Presence of Amylose (starch)
Behavior of Lipids (fats)
Actions of Enzymes on Proteins
Testing pH using Red Cabbage or Blueberry Juice
Making Homemade Yogurt
Osmosis using Chicken Eggs
Osmosis using Fresh Veggies
Creating a (functional) Cell Model
Using Homemade Playdough to create a Mitosis Model
Building a DNA “Ladder"
Growing Edible Mushrooms on Toilet Paper (supplies purchased separately)
Dissections of Fresh Specimens are presented by video (available separately) See Video Instruction tab for information.
