Mars, Earth, and Venus contain atmospheres that generate weather. Young scientists explore the temperature of inner planets. They create a model simulating the greenhouse effect before researching and answering guided questions to...

Aspiring astronomers assess the inner planets using this handout. They read about the characteristics of each, noting that all four of them have rocky surfaces. Rotation and revolution are introduced, including Venus' retrograde...

All of the gas giant's atmospheres consist of hydrogen and helium, the same gases that make up all stars. The third in a series of 22, the activity challenges pupils to make scale models of the interiors of planets in order to...

In this space science worksheet, students read the five descriptions of various planets and match the description with the picture of the planet.

Take young scientists on an exploration of the cosmos with this cross-curricular writing exercise. Tasked with producing an expository composition describing a planet of their choosing, students perform research and...

Scholars gain an insight into the relative size of planets and distance between inner and outer planets with the help of informational text, a data table, and a series of four questions.  

Looking to take a trip? Why not go to space? Here, scholars take on the role as travel agent to create a guide to their favorite planet including travel tips and sightseeing recommendations. 

Ever wonder why Pluto isn't considered a planet? Or how large the Earth is compared to the other inner planets? Explore the universe with a series of projects that simulate different aspects of our solar system. The activities require...

The presentation starts with the scientists who made discoveries about our solar system: Ptolemy, Copernicus, Galileo, Brahe, Kepler, and Newton. It also covers the planets, inner, outer, and Pluto, satellites, and an in-depth discussion...

Come take a ride on the space bus! Scholars go on an imaginary trip to pick up their peers from the inner and outer planets while reinforcing math skills. First, learners round decimals to identify each planets' distance from Earth....

Fly around the Martian surface. Pupils view a presentation on the planet Mars featuring a flyover that shows different views of the surface where rovers have landed and explored on different missions. As individuals watch the images, the...

Young astronomers read an informational text passage and then answer questions based on what they read.

Scholars go on a hunt to locate objects that best fit the measurements to create an eye-catching scale model of the solar system. 

New Horizons set forth on a mission to Pluto in 2006. Ten years later, the spacecraft is still on its way. Here, enthusiastic scholars predict what they will be like—likes, dislikes, hobbies, etc.—when New Horizons arrives at its...

In 2006, New Horizons began its mission to fly to Pluto. As it continues its journey, scholars track its progress with the help of an informative website, all the while reinforcing measurement concepts with the construction of a scaled...

New Horizons began its journey to Pluto in 2006. Ten years later, it continues its mission. In that time, scholars have surely grown, but how much more will they grow by the time New Horizons reaches its destination? Find out with an...

A read-aloud anthology focuses on Earth's history. Over three weeks, young scholars listen to and discuss stories about the layers of the Earth, minerals, fossils, different kinds of rocks, and dinosaurs. After the lesson's text, each...

A slideshow and a short multiple-choice quiz on the four inner planets of our solar system, which include Mercury, Venus, Mars, and Earth.
