NASA向老师们致敬！

May 2-6, 2022, is Teacher Appreciation Week! At NASA, we know the importance of STEM (science, technology, engineering, and math) education, and we provide lesson plans and other tools to help out classrooms.

Visit NASA STEM Engagement for lesson plans and more.

In the Discovering Alien Oceans: Density lesson, teachers will help their students to learn more about Jupiter’s icy moon Europa, by using the mass and density of known substances to predict what exists underneath the surface.
