    Hydra Microscope Lab
    Free Lesson Plan
     
    Lab
    Students will observe a living and a preserved hydra using a microscope. Students will then draw what they observe and label the parts. Third, students will touch the hydra and to see how the it reacts. Last, students add some food to the slide and maybe watch the hydra feed.

    Mendelian Genetics Lab - Dragon Genetics
    Free Student Handout
    Free Teacher Notes
     
    Lab
    In this genetics lab, students use Popsicle sticks to represent a pair of homologous chromosomes with multiple genetic traits. Teams of students use their sets of Popsicle sticks to model fertilization and then identify the genetic makeup and phenotypic traits, resulting in a fictitious baby dragon.
