Students read "A Minerals Story" while circling the words in the story that represent minerals. They find the words amber, gold, Feldspar, Galena, Copper, tin, gold, silver, iron, Quartz.

In this marine animal worksheet, 3rd graders study the parts of seaweed. Students label 2 seaweed diagrams and study 24 household objects, circling those that come from seaweed extracts and/or ingredients.

In this recognizing words about bats learning exercise, students unscramble letters to make words and use the letters that are circled to identify the answer to the riddle. Students write 7 answers.

Learners will like making a liquid layer cake to investigate the relative densities of various liquids: water, oil, and corn syrup. They will also introduce a few solid materials to find out how their densities compare. Standing alone,...

Fourth in a set of several little lessons on density, this one compares the density of fresh and salt water. First by demonstration, and then by a hands-on activity, learners find that adding salt increases the density, as is evidenced...

Conclude this chemical change unit by having your class combine two liquids that result in formation of a precipitate. The learners discover that chemical reactions result in new materials. Make sure to consider all of the preceding...

Continuing with the concept of volume and its effect on density, learners now work with a piece of clay to see if they can get it to float in water. This is a memorable end to a seven-part investigation of density. Make sure to check out...

Here is a word search that has more educational value than most. After finding the 14 words that have to do with natural resources, learners must then use the words in context. They answer 14 questions on the second page of the...

Course identification information is included in the upper left corner as well as within the title of this worksheet. If you overlook or remove that information, you are left with a tremendous college biology assignment. There are only...

Now that your science class has experimented with pH indicator and identified acids and bases, they attempt to get the cabbage juice indicator back to its original color. This is done through neutralization of the acids and bases that...

Students evaluate the impact of volcanic ash on the surroundin environment. Through discussion, videos and activities, they identify the various ways in which volcanic ash can be more detrimental than volcanic magma and lava.

High schoolers conduct discussions on current threats to coral reefs around the world and write letters to conservation organizations urging support for coral reef protection.

Students study watersheds and use topo maps to help explore where they are located.  In this watershed lesson students delineate their watershed on their own. 

Learners will use their bodies to act out the motions of Earth by exploring orbits, rotations, and the turning of the earth as it revolves around the sun. Doing research to find correct answers to their questions will help them act out...

Students explore placing a satellite into orbit, then about forces needed to keep an object in orbit. They examine how satellites orbit in elliptical paths and about properties of ellipses. They learn Kepler's 3rd Law of Planetary Motion

Students examine the tropical rainforest and issues involving the uses of rainforests. They explore the plants and animals that live in each level of the tropical rainforest. Students examine and discuss a case study involving the rights...

High schoolers investigate the history and use of the Hubble Space Telescope. They take a quiz in order to establish in any prior knowledge. Students conduct research to find information in conjunction with participating in class...

In this earth science instructional activity, students check the accuracy of the weather forecasts in their area for a week. Then they complete the chart by recording the forecast for the week's weather and then recording the actual...

Students identify major rivers in the world. In this geography lesson, students form teams and play a whole class board game in which clues are read and rivers are identified.

Learners examine student created maps to locate geographical features such as hills, cliffs, flat meadows, stream beds, etc. They use watershed topo maps to identify landmarks, water flow, and elevation of several features. In addition,...

Students examine the types of hawks found in Illinois and compile a list of them. Using different species of hawks, they compare and contrast their characteristics. They work together to create their own hawk model for the classroom.

Students investigate the universe through the eyes of the Hubble space telescope. They conduct research from looking at the universe that is simulated with a digital projector. The images are projected onto the wall in a simulation of...
