Young scholars experiment with the visocosity of corn syrup, mineral oil, vegetable oil, water, and honey. They research viscosity before beginning. Pupils draw the conclusion that the marble sinks more slowly in the liquids with greater...

Which vitamins should be ingested daily for maximum nutrition? Learners with ispecial needs or those who are pregnant focused on television and magazines advertisements that are used to sell food products. They conduct experiments and...

How do you measure surface tension? The fifth installment of a nine-part series is an experiment where young scientists use tubes of different sizes to measure surface tension. They calculate the average and standard deviation of the...

The Fantastic Voyage is becoming close to reality. The class reads an article on the use of nanotechnology in the medical field and participate in a discussion about what they read. The discussion method helps class members become more...

When it comes to writing, cliches are as old as dirt. A handout on tired phrases provides examples of cliches, as well as a description of the negative effects they have on a paper. Writers discover specific words and phrases to avoid,...

This isn't your typical basic lesson—it's more acidic! Learners use pH information to determine the hydroxide ion concentration of different substances and then use these values to analyze information. The calculations require...

How is sea coral like a thermometer? Part three of a six-part series from NOAA describes how oceanographers can use coral growth to estimate water temperature over time. Life science pupils manipulate data to determine the age of corals...

Students study Avogadro's law and what it means in science.  In this gaseous instructional activity students complete an Avogadro's law experiment.   

You will need a photovoltaic system and monitor at your school in order to obtain all of the data required to thoroughly implement this lesson. Your class monitors daily temperature and insolation amounts over a two week span of time....

Investigate how temperature affects the density of water and stratification that occurs in bodies of water when temperatures vary. Water of differing temperatures is given different colors to see the layers that form. The lesson is meant...

Four lessons introduce elementary ecologists to salt marsh and sandy beach habitats. In the first lesson plan, they place shells and other materials in vinegar to determine if they contain calcium carbonate. In the second lesson plan,...

In this comma rules worksheet, students read 30 sentences and add commas where needed. Detailed rules for the use of commas are on the page to help.

Third graders investigate different energy conversions through hands-on activities. In this energy lesson, 3rd graders move through four stations and conduct experiments illustrating energy conversions. Wave energy, chemical energy,...

Students identify auxins from their structural formulas. They understand the process of refluxing in chemical synthesis. Students perform thin layer chromatography using silica gel plates to differentiate chemical substances.

Students describe the law of conservation of energy. They identify the conversion between potential and kinetic energy. They investigate and describe the application of Newton's Laws of Motion.

High schoolers work in teams and train in the methods of anthropometry, the measurement of the human body. These activities require calipers or measuring tapes, meter sticks, skin fold calipers, and human skeleton.

Students design and construct a battery (electrochemical cell). They works in a team to design and construct a working battery and is responsible for a labeled diagram of its operation. This engaging lesson stimulate their creative juices!

Young scholars explain hardground communities in the Gulf of Mexico. In this deep-sea ecosystem lesson, students investigate the connection between deep-sea ecosystems and petroleum deposits. They discuss the relationship between...
