How much do you really know about our planet? Middle schoolers build up their prior knowledge about Earth, its placement in the solar system, its composition, and important geological vocabulary with an introductory earth science lesson.

Second graders distinguish the different phases of the moon. In this astronomy lesson, 2nd graders study the history of its discovery and myths about its origin. They simulate how the moon's surface is illuminated by the sun.

Huygens spacecraft landed on Saturn's moon Titan in 2005, making it the farthest landing from Earth ever made by a spacecraft. In this hands-on activity, the 12th installment of 22, groups explore how density affects speed. To do this,...

Earth is a complex structure. Learners explore their home, the earth, using a fun hands-on activity. They create tactile models of the earth using ordinary household materials that represent some common features: land, polar caps,...

Students write and communicate mathematically with their classmates. They discuss the mathematics that it took to allow us to conquer space and land on the moon. They sketch a plaque they would leave on the moon.

Students explore Earth's seasons using an interactive website. In this earth science lesson, students watch video segments and explain Earth's seasonal milestones. They discuss the factors that causes seasonal changes.

Students simulate crater formation through a lab activity. In this space science lesson, students calculate how much energy is transferred during meteorite impact. They identify different factors affecting the size and depth of craters...

Learners extract DNA from split peas. In this biology lesson, students research how chromatin form into chromosomes. They draw the stages and present their work in class.

First graders examine space in this unit of lessons. They create a KWL chart and write in their journals about space. They also examine the phases of the moon and identify the constellations.

Young scholars design a South Pole base. In this science lesson plan, students discuss characteristics of the South Pole and work in a group to design a base that will be named "Gamma." Young scholars sketch their design.

Young scholars explore the nature and composition of a comet. They research comet facts, legends, and myths. They identify different types of comets and describe what happens to a comet as it travels closer to the Sun.

Students investigate the concept of a watershed. They conduct research into the concept using a variety of resources. Students take a field trip to a local watershed to make observations. The outcome is a report concerning the outside...
