Students complete a unit of lessons on the four seasons. They examine the effect each season has on plants, animals, and people during the actual season, read magazine and newspaper articles, and create a calendar and poster about each...

In this grade 4 science learning exercise, 4th graders complete 25 multiple choice questions covering a variety of 4th grade science concepts. An answer key is included.

A website looks at how we know so much about Mars—telescopes, robots, and spacecraft—and the search for martian life. Following the informational text are three questions that quiz pupils about possible life on Mars. 

Students investigate the temperature and wind data locally, nationally, and internationally and compare these conditions to those on Mars. Conclusions are drawn about the differences of these conditions and the causes for the variance...

Second graders recall the affect of direct and angled sunlight on the seasons, describe some results of warming soil and air in spring, predict the changes in buds when twigs are placed in water, and taste a product of tree sap and...

Students think about what causes the seasons to change, reflect on what they know about seasons and how their lives affected by seasonal changes.

Students complete a unit of lessons on our solar system, its stars, and astronomers. They record information in a space journal, design constellations, define key vocabulary, observe the phases of the moon, and create a group planet...

Young scholars examine the elevation of the sun to discover the changes in seasons. They observe and measure the length of their shadow. They compare this measurement to one taken four months later.

In this climate changes worksheet, students review the different events such as volcanic eruptions and El Nino that change the climate. This worksheet has 5 multiple choice and 5 short answer questions.

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...

Students perform many inquiry activities related to Earth's orbit. Included are recording daily temperatures, observing the sun's path over several weeks, tracking sunrise and sunset times, and angle of sunlight. Diagrams make lessons...

[Free Registration/Login Required] An interactive animation demonstrating the Earth's tilted axis and how that causes the seasons. Also included on the site is a short quiz on the topic.

[Free Registration/Login may be required to access all resource tools.] Discusses the motion of the Earth with its day and night cycle, the seasons, the Earth's orbit around the Sun, and its year-long cycle.

This interactive activity from the Adler Planetarium explains the "reasons for the seasons." Featured is a game in which Earth must be properly placed in its orbit in order to send Max, the host, to different parts of the world during...

Why do some regions experience full-time heat while others are reckoning with frigid temperatures and snow? And why are the seasons reversed in the two hemispheres? Rebecca Kaplan explains how the shape of the Earth's orbit around the...

A video and a short multiple-choice quiz on how the Earth's tilt on its axis, its rotation, and its orbit around the Sun give us a 24-hour day, a 365-day year, and our seasons.

A slideshow exploring Earth's rotation and revolution around the sun. Learn that because of Earth's axis tilt we experience the seasons!

Presents an informative answer to the question "What is the speed of the turning of the Earth?"

This kinesthetic activity will demonstrate concepts like rotation and orbit, clarify movement and direction, and help students understand why earthlings see different things in the sky.

Students model the interaction of the earth and the sun. The activity is designed for the playground. You will need chalk, but all the other worksheets are provided.

Nutation is a small cyclical motion superimposed upon the steady 26,000-year precession of the Earth's axis of rotation. It is mainly caused by the gravitational effect of the 18.6-year rotation period of the Moon's orbit. The main...

Third graders use their bodies to act out the motions of earth.

A lesson for third graders in which they learn about the rotation of the Earth on its axis and how this movement creates day and night. They also examine the orbit of the moon about the Earth and the Earth's orbit around the sun.
