Fill out this worksheet while going through the following lessons: "Investigating the Great Salt Lake Timelapse," "Finding Evidence From a Graph," and "Salinity Graph" in 3rd and 4th grade.
Use this key to go over answers to the "Graphs of Great Salt Lake Worksheet."
This task requires students to recognize the graphs of different (positive) powers of x.
This task requires students to recognize the graphs of different (positive) powers of x. There are several important aspects to these graphs. First, the graphs of even powers of x all open upward as x grows in the positive or negative direction. The larger the even power, the flatter these graphs look near 0 and the more rapidly they increase once the distance of x from 0 excedes 1.
This exploration can be done in class near the beginning of a unit on graphing parabolas. Students need to be familiar with intercepts, and need to know what the vertex is. It is effective after students have graphed parabolas in vertex form, but have not yet explored graphing other forms.

In this video segment adapted from NOVA, watch residents of the Peruvian Andes build a suspension bridge made entirely of grass. The ancient Inca were a textile society and thus skilled in working with natural fibers including alpaca and cotton. Still, it might surprise people today that their solution to crossing the canyons and gorges of their mountainous empire featured another fibrous material: grass. When you consider how they built a simple suspension bridge, you'll realize that not only was this a practical solution, it was also a safe one. In this video segment adapted from NOVA, watch residents of the Peruvian Andes as they build a traditional and functioning grass bridge the likes of which enabled the ancient Inca people to flourish for several hundred years. Grades 3-12.
This task requires students to think about and compare fractions.
This is a lesson plan about Grassland Animals. Students will become familiar with habitats and what types of animals can be found in grassland areas. They will create a slide show using Keynote and present it to their peers. They will use a graphic organizer to gather information for their slide shows.
Desert grasslands exist in Arizona, New Mexico, and parts of Texas and Mexico.
This map demonstrates the worldwide distribution of grasslands.
The map illustrates two major groups of grasslands in the Great Plains: shortgrass prairie and mixed prairie.
It is hard to imagine any movement more important for understanding the meaning of freedom and equal rights in the U.S. than the civil rights struggle in the post-World War II era. Yet, as Julian Bond succinctly argued, in most textbooks and the media, the popular understanding of that movement is reduced to: "Rosa sat down, Martin stood up, and the white kids came down and saved the day."

This resource is a Science student activity that utilizes Utah's Online Library resources - specifically, Gale's Kids InfoBits and eMedia - to help students learn about gravity.
Visualize the gravitational force that two objects exert on each other. Adjust properties of the objects to see how changing the properties affects the gravitational attraction. (Phys 3.1, 3.3, 3.4)
Visualize the gravitational force that two objects exert on each other. Change properties of the objects in order to see how it changes the gravity force.
Visualize the gravitational force that two objects exert on each other. Discover the factors that affect gravitational attraction, and determine how adjusting these factors will change the gravitational force. (Phys 3.3)
Move the sun, earth, moon and space station to see how it affects their gravitational forces and orbital paths. Visualize the sizes and distances between different heavenly bodies, and turn off gravity to see what would happen without it! (Phys 3.1, 3.3, 3.4)
