Students observe crystals under the microscope. In this science lesson plan, students compare how the crystal look like using their eyes, hand lens and microscope. They identify the type of crystal based on the amount of light they allow...

Students collect, interpret and analyze weather variable data. They describe atmospheric variables that affect evaporation. Students create graphs and analyze the information collected.

High schoolers recreate sea-floor spreading and the pattern of magnetic stripes that are created by different configurations of plate boundaries. They see how transform faults work.

Seventh graders examine the job of meteorologists. They decide which characteristics of the atmosphere that meteorologists focus on. They use local weather maps from newspapers to predict weather in their area.

Students investigate techniques involved in extracting and isolating DNA. Students extract and observe onion DNA.

Young scholars plot the locations of fallout from two disasters that polluted much of the world's air. They plot the ash fallout from the 1980 Mt. St. Helen's eruption to see what the wind patterns in the United States look like overall....

Second graders become familiar with the lives of penguins including their life cycles, habitats and basic needs. Students will experience the lives of penguins through stories and video.

Third graders make observations about the temperature of items in direct sunlight. In groups, they discuss why asphalt, brick and cement are warmer than items surrounding them. To end the lesson, they examine how heat transfers energy...

In this environment and animals activity, 7th graders match ten pictures with their actual titles, answer seven statements as true and false, and discuss six questions together.

Learners study the physical characteristics of four types of desert regions. In this desert regions lesson, students watch a video about deserts and discuss the deserts. Learners compare the deserts and research the ways humans have...

Students examine Shamanism and explore the Inuktitut language. In this Inuit culture lesson plan, students role play and 'interview' a shaman. Students encounter native Inuktitut words and then use a dictionary to find their English...

In this English worksheet, students read " Arctic Ice May Disappear in a Decade," and then respond to 1 essay, 47 fill in the blank, 7 short answer, 20 matching, and 10 true or false questions about the selection.

[Free Registration/Login may be required to access all resource tools.] Covers structure of water molecule, hydrogen bonding on water, polarity of water molecule, and bond angles of water molecule.

Water is both essential and unique. Many of its particular qualities stem from the fact that it consists of two hydrogen atoms and one oxygen, therefore creating an unequal sharing of electrons. From fish in frozen lakes to ice floating...

Lesson plan with mulitmedia links in which students identify and control variables to help design a solubility test for different liquids in water.

[Free Registration/Login may be required to access all resource tools.] Students look at the chemical structure of water and learn how it determines water's properties.

Students develop their own water molecule model to help them understand the idea that water has a slight positive charge at one end of the molecule and a slight negative charge at the other.

[Free Registration/Login may be required to access all resource tools.] In the following online tutorial students will describe the structure and polarity of a water molecule. They will also describe the hydrogen bonding that occurs in...

Water on the Web (WOW) is an advanced site allowing students to actively participate in data analysis from real research sites. Lesson plans on a range of topics are provided. There is also a tutorial for using Excel to graph WOW data.
