This WebQuest is modified from a WebQuest found at Science-Class.net.
Websites current as of August 6, 2012
This WebQuest covers the following Utah 6th Grade Science Standards:
STANDARD II: Students will understand how Earth’s tilt on its axis changes the length of daylight and creates the seasons.
Objective 1: Describe the relationship between the tilt of Earth's axis and its yearly orbit around the sun.
Objective 2: Explain how the relationship between the tilt of Earth's axis and its yearly orbit around the sun produces the seasons.
Why do we have seasons? Why is winter colder than summer? Is it because the Earth is closer to the Sun in summer than winter?
This WebQuest will help you understand the reasons for the seasons. Take your time and complete each task carefully. If you do, you’ll be surprised just how much you will learn.
You have been hired by an educational publishing company to produce posters for middle school science classrooms. Your first poster is to be one that shows the causes of seasons on Earth.
Since many students have the wrong idea about what causes seasons (they think that they are caused by the Earth being closer to the Sun during the summer) it is very important that your poster be very accurate. Your poster will answer the question "What causes seasons".
After you have researched the information for your posters, you will go back to the classroom and make your posters. If you haven’t been given the WebQuest worksheet and requirements, click here.
Your first poster will identify misconceptions students have about the seasons. What are these misconceptions? Use the resources below to find common misconceptions students have about the reasons for the seasons.

Once you have the information about the misconceptions, it’s time to learn the real reasons.
It’s the Tilt, Baby!
The real reason for the seasons is the tilt of the Earth. Go the websites below. Use the information you learn from the websites to explain the tilt of the Earth. You will need this information to make your second poster.

Earth Location and Seasons
As the Earth revolves around the Sun, the tilt of the Earth affects the seasons. The direction of the tilt never changes. It is always pointing towards the North Star (Polaris). Using the information from the websites, you will make your third poster. Your third poster will show the location of the Earth at each season. Make sure the tilt is in the right direction!
What’s Your Angle?
We have learned that the Earth’s tilt is responsible for the seasons. We have also learned how the position of the Earth as it goes around the Sun affects the seasons. The next question is, “How do the tilt and the Earth’s position affect the seasons?” Use the resources below to get the information you need to make your fourth poster.
You have been given a copy of the the rubric telling how your posters will be graded.
As you have researched the information required for the posters, you have learned about the reasons for the seasons. Your challenge is to remember this information and share it whenever someone does not understand the reasons for the seasons.
