Paper Towel Absorbency Test – Scientific Method Lesson
Put scientific-method ideas into practice by comparing how much water different paper towels absorb. Students plan a controlled comparison, record measurements, calculate averages and use a graph to support their conclusion. Student notes and matched completed slides introduce variables and hypotheses beforehand, while an extension sheet suggests changing the liquid or measuring absorption time for a later investigation.

Melting Ice Experiment | Water Unit Journal
Record what happens to ice left on a table using a simple observation journal. Children draw the ice before and after the observation period and complete an I observed response. Discuss what they notice rather than supplying the conclusion first. The page provides a way to compare two observations during a water or changing-materials lesson.
