Welcome to the wonderful world of Nerdling Science. My name is Heidi Tarr, AKA the Queen Nerdling! I have 13 years of experience in teaching AP Biology, Honors Biology, APES and genetic studies. I am also a content developer teacher coach, and professional presenter for NMSI (National Math and Science Initiative). I have a crazy, quirky personality and a LOVE of bringing laughter and biology to life in my classroom. I hope you will find my biology videos and website both entertaining and informational.
