Three chemistry beakers bubbling. One has square bubbles, one round, one star-shaped.

About this page

Three beakers bubble away on page 54, and each one bubbles in its own surprising way. This playful scene sneaks in a big idea from Chapter 4, The Adventure Kit, which is that experiments compare things. When researchers mix different ingredients, they watch closely to see what changes. The square, round, and star-shaped bubbles give kids an instant lesson in comparing results side by side. It also celebrates the pure joy of experimenting, because sometimes the best question in science is simply, what happens if we try it this way instead?

The research skill

Comparing results side by side is what these three smiling beakers invite, and the trick is noticing that only one thing differs: the shape of the bubbles. When researchers plan an experiment, they keep everything the same except the one thing they are testing, so any difference has a clear cause. That idea, changing one variable at a time, sits at the heart of Chapter 4's planning. It returns in every school science fair project, where using the same cups, the same amount of water, and the same timing is what makes a comparison fair.

Try it at home

Line up three clear cups of warm water at the sink, with an adult helping. Keep the amount of water the same in every cup, and change only one thing: a squirt of dish soap in the first, a spoonful of sugar in the second, and nothing in the third. Your child blows gently through a straw into each cup (blow out only, never sip) and describes the bubbles. Which cup made the biggest, longest-lasting bubbles? Draw the results next to the beakers on the page.

Talk about it while you color

  • Which beaker would you want to peek into first, and why that one?
  • What do you think was mixed into the beaker with star-shaped bubbles?
  • If you had a fourth beaker, what shape would your bubbles be?
