Science labs should feelĀ approachable, doable, and actually enjoyable,Ā even if you donāt have a full lab setup or years of experience running experiments. Iāve 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.
Thatās why I create labs that areĀ simple to prep, easy to run, and realistic for real classroomsāwhether youāre 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.
Letās make hands-on learning possible for everyone. No fancy equipment required. You’ve got this, and Iām here to help.
Lab Summary
In the yeast respiration lab, students explore how yeast breaks down sugar to produce energy and carbon dioxide gas. After combining yeast with warm water and different types of sugar in bottles topped with balloons, they observe the balloons inflating as COā is released. By measuring balloon circumference over time and comparing sugar types, students see clear evidence of cellular respiration and fermentation in action. This simple, low-prep activity makes abstract life science concepts like aerobic versus anaerobic respiration tangible and memorable, while connecting to real-world applications such as bread making and brewing
