Tenth graders, from an environmental perspective, study the pros and cons of war. Distinctions between characteristics of biological, chemical and nuclear threats and the impact of economic development are considered.

Here's a great geology lesson plan for 3rd graders on weathering and erosion of soil. After a class discussion on how nature can "move a mountain," learners take a look at how a modern phenoma called acid rain can also cause weathering...

Be at the top of the food chain when it comes to understanding marine ecosystems. The 21st installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program investigates marine ecosystems, ocean zones, and food...

Once your physical science stars have a grasp of the different forms of energy, use this resource to get them putting the energy to work. Small groups choose from seven different project options and work together to build an energy...

Fifth graders mix vinegar with different substances and explore the reaction. They record data from the experiment. Students examine chemical change, reaction, physical change and physical reaction.

Pupils review what they know about non-renewable energy, compare and contrast advantages and drawbacks of each type, such as cost of energy sources, feasibility, air pollution, water pollution, and other risks, and create table listing...

Eighth graders sort items as they are shown one at a time by the teacher. They attempt to identify the one physical trait the teacher is looking for (metal and not metal). After several objects have been shown and placed in groups, the...

Discover the change of the seasons by modeling the Earth-Sun system. Learners model the orbit of the Earth around the sun and explore how and why the patterns of winter and summer occur.

In this energy transformations worksheet, students fill in the objects to a chart for which one would fit each energy transformation, and fill in the blanks to a chart about which energy transfer fits each object. Students complete 6...

Fourth graders study physical and chemical weathering. They explain how the processes of weathering and erosion change and move materials that become soil. They create a K-W-L chart to show what they know and list what else they would...

In this weathering worksheet, students read about physical and chemical weathering and how kaolin in used in paper. Then students complete 4 short answer questions.

In this matter worksheet, students watch a movie and then compare the differences between compounds and mixtures. This worksheet has 16 fill in the blank questions.

Students complete a unit of activities to learn about states of matter and how to measure matter. In this matter lesson, students complete 8 lessons to learn about matter, its states, and how to measure matter.

In this earth and beyond science worksheet, students read through 11 pages of information on weather, global warming, climate change and other related topics. There are many website links on the pages that provide additional information...

Students measure in metric units and use a stopwatch, calculator. They collect data with minimal instructions after the initial pre-activity briefing, then record data in the data sheets provided.

Once investigators have learned how their mystery liquids interact with water during the preceding activity, they now use their observations to identify them. This is an ideal conclusion to the mini unit on the properties of water. 

Students investigate quality of water in a stream, lake, or pond by examining chemical, physical, and biological characteristics.

Third graders conduct experiments in matter to create chemical changes resulting in gases. By mixing solids and liquids, they create a chemical reaction and capture the gas in balloons. After observing the balloons fill with carbon...

Learners predict when an object will float or sink based on comparison of density of the object to the density of the substance in which it is placed. The access a website and sketch the object in the first column of their table and then...

Combine mathematics and science to calculate measurements of unmeasurable materials. Individuals use knowledge of density and volume to determine the thickness of the film used in production. They also apply stoichiometry to...

Middle school marine scientists compare the pH change in distilled and saltwater as acetic acid is added one drop at a time. Then they compare the pH change in both when sodium hydroxide is added. This experiment demonstrates the...

Students test water to determine the dissolved oxygen content while displaying the proper use of testing instruments while visiting water testing sites. They determine if the amount of dissolved oxygen is appropriate for the tested...

Chemistry and earth science meet in a lesson on carbon dioxide emissions. After reading about atmospheric problems caused by using fossil fuels, science stars balance equations for the burning of different alkanes. They compute the...

Several slides compare different temperature scales. Thermal expansion, heat transfer, and Maxwell speed distribution are also explored. The last two slides seem unrelated to the topic of heat, but are easily left out of this otherwise...
