Vivi loves science—and experimenting! When Vivi and her classmates visit the aquarium, they learn about the many aquatic creatures living in the big display tank. Why do some fish swim and others bury themselves in the sand? This exploration of swimming, sinking, floating, and density includes an experiment to try at home and encourages collaboration and asking questions. The Loves Science books introduce readers to age-appropriate concepts of science, technology, engineering, and math. This Level 3 I Can Read! is perfect for newly independent readers and curious kids.
