How hot is the sun? Why do comets have tails? How do scientists study asteroids? This series for ages six and up invites young explorers on an adventure Across the Universe to discover the wonders of the cosmos and how they relate to life on Earth. Simple text set within a technology-themed design encourages curious minds to make observations and comparisons, while a hands-on activity in each book provides further exploration of a scientific concept presented. A valuable addition to low-level STEM curricula.
