See the water filtration system up close with a fun science experiment. Young scientists work for several class periods to design a water filter using household objects, and then decide which filter material would be most effective...

Shake up your lessons on earthquakes. A simple seismograph lets scholars record "earthquakes" in the classroom. These earthquakes occur when classmates drop balls from different heights. Young scientists measure these with seismographs...

Compounds take on different properties than their elemental components. How can scientists determine those elements? A lab-based activity has learners explore several double replacement reactions to analyze compounds qualitatively. They...

An interactive lesson places pupils as scientists who must learn why the ozone layer is being destroyed by analyzing the data from multiple satellites. The first analysis shows how UV is related to the ozone cycle. The second...

How hard do you need to throw a ball in the air so that it never returns? Scientists call this measure the escape velocity. Classes can explore this concept through an intriguing interactive lesson. Pupils adjust velocities and observe...

Will human existence define an epoch? Many scientists think we are in a new epoch, the anthropocene, defined by humans and our impact on the environment. An online interactive demonstrates the immense impact humans have had on every part...

Leave it to science to get scholars out of a jam. Young scientists use what they've learned about electricity and magnetism in the previous eight lessons in the series to build tools that will allow them to find their way out of the...

In this origin of life worksheet, students write answers to five questions. They describe characteristics of the first life forms and how scientists believe oxygen accumulated in the Earth's atmosphere.

This set of black-line diagrams of the three different types of faults can be used with your upper elementary earth scientists. Simply have them color the layers to show where the land once lined up. Another use for this resource would...

Science stars unscramble twelve terms associated with the landforms and natural resources of the southwest United States. Print out this worksheet and assign it to your middle school earth scientists. Have them write definitions for each...

First educate, and then quiz viewers on the ins and outs of weathering and erosion. At a level appropriate for upper elementary or middle school earth scientists, these slides display animated graphics and photos. The first 22 slides...

Young scientists identify erosion, explain the causes of erosion, and name some techniques that can slow the process of erosion. Learners are divided up into groups of four and perform a simulation of soil erosion in class. The...

There are only four questions here. There is a contour map of Cottonwood, Colorado and the creek that crosses it. Earth scientists tell in what direction the creek flows, identify the highest elevation on the map, draw a topographic...

Young scientists examine why we have seasons on Earth, and how the motion of the Earth around the Sun causes them. Groups of learners are given a variety of balls, a bamboo stick, a marker, and a flashlight, then use the objects to...

Young scientists demonstrate how the Earth's temperature has varied gradually in the past. They attempt to answer four questions which all pertain to how the Pacific Ocean's temperature has evolved over time. Internet research, and a...

Use an online interactive worksheet to guide your young scientists into the fascinating world of tornadoes! Links to weather articles from the National Weather Service and Planet Diary give clear explanations as well as visual depictions...

Students study cloud data and weather maps to explore cloud activity.  In this cloud data lesson students locate latitude and longitude coordinates and determine cloud cover percentages. 

The class gets to practice being a mathematician in ancient Greece, performing geometric application problems in the way of Eratosthenes. After following the steps of the great mathematicians, they then compare the (surprisingly...

Here's a stat for your pupils: 18 percent of the human body is carbon! Part 10 in the series of 12 takes pairs on an adventure through the carbon cycle. After a class reading about carbon, pairs read and choose their own adventure...

Middle schoolers explore the history of the Caddo Salt Industry found in Arkansas. Along with learning about how salt deposits formed in Arkansas, learners study the process of salt production and how valuable salt is as a natural...

Young scientists create their very own aquifers in this science lesson on ground water. After learning about how some people get their drinking water from underground wells, young learners use sand, modeling clay, and aquarium rocks to...

Scholars collect data from heating sand and water before forming testable hypotheses about why sand heats up faster. Afterward, they develop and run experiments to test their hypotheses.

A celestial body's distance from Earth makes studying its characteristics much more difficult. Learn how scientists use indirect measures to determine the size of stars. The interactive activity has individuals adjust the size of binary...

Follow a fabulous slide show on how monsoons form and how satellite technology is being used to observe the phenomena, explaining why they occur. Afterward, visit the TRMM (Tropical Rainfall Measuring Mission) website to access actual...
