Science labs should feel approachable, doable, and actually enjoyable, even if you don’t have a full lab setup or years of experience running experiments. I’ve taught in classrooms without sinks, with wild class periods, and with barely enough materials to go around. I know how intimidating labs can feel when the logistics seem overwhelming.
That’s why I create labs that are simple to prep, easy to run, and realistic for real classrooms—whether you’re a first-year teacher or a seasoned pro. My goal is to take the stress out of labs so you can focus on what matters most: helping your students explore, question, and fall in love with science.
Let’s make hands-on learning possible for everyone. No fancy equipment required. You’ve got this, and I’m here to help.
Activity Summary
The Reebop Offspring Activity is a fun, hands-on genetics activity that helps students explore how traits are inherited from parents to offspring. Using imaginary marshmallow creatures called Reebops, students model meiosis and fertilization by randomly selecting alleles from each parent to determine the baby’s genotype and phenotype. Then, they build their unique Reebop using simple craft materials, comparing their creations to classmates’ to see how genetic variation arises. This engaging lab makes abstract heredity concepts—like dominant and recessive alleles, genotype, and phenotype—concrete and memorable for middle school learners.
