What is the ocean? What is it made of? And how does it work?
Find out all about the ocean - how it functions, how pollution affects it, how animals live in it - by following the experiments in this fun science book. Using simple household items, young scientists can discover what makes the ocean salty, how ocean currents are formed, what happens when pollutants mix, and how fish hide themselves from predators. Kids can also create underwater volcanoes, imitate sea stars, or use the bathtub to observe tsunamis and icebergs.
An excellent, hands-on book, perfect for home schoolers and independent learners.
