The elephant toothpaste STEM activity is to demonstrate how exothermic reactions work. The washing up liquid when mixed with hydrogen peroxide and oxygen creates a foam, or 'elephant toothpaste', that's fun to watch grow. The oxygen-filled bubbles, which make up the foam, are actually the remainder of what happens when the hydrogen peroxide breaks down into water (H2O) and oxygen (O2). The bottle will feel warm to the touch because this is an exothermic reaction in which energy, in the form of h

Did you know that our cells produce hydrogen peroxide as a byproduct of normal cellular processes? Our body synthesizes Catalase, an enzyme and biocatalyst, to decompose hydrogen peroxide into water and oxygen. Biology students catalyzed this reaction in the lab and then tested the effects of pH and temperature on enzymatic activity. They found that high heat denatured their enzymes, extreme pH levels had the same outcome, and cold temperatures make enzymes sluggish. 🧪 | St. Bernard's Academy S
