Chemistry classes pretend to be consultants to a grocery story trying to decide what polymer to use for therir new non-paper bags. They prepare tensile bars and use them to test plastic film samples for strength and stretchability. Both...

Advanced lab apprentices prepare zinc and copper solutions to which they will compare the same minerals from a multivitamin. Using absorption spectroscopy, they analyze the contents of the multivitamin for concentration. This lab can be...

The human body is an amazing thing! Explore the body with your high school class as they investigate each system in detail. They learn components of each organ system and disease processes that can negatively affect general health and...

Explore the concept of density within states of matter—gases, liquids, and solids—through a group experiment in which young scientists test objects' texture, color, weight, size, and ability to sink or float.    

Sixth graders design experiments to compare the amount of bacteria in river water to the amount in purified tap water. They explore how water purification removes bacteria and pollution from the water. Students examine the steps of the...

Activate middle schoolers' minds with this physical science activity. Learners vary the diameter of gears and the number of teeth on them to find how energy output is affected. This writeup features well-developed background...

You can create a camera with even the most unassuming materials. Learners view photographs and talk about the art. Some background information is included about the camera obscura for you to present before individuals make their own...

Speaking of the Internet. The culminating lesson for the unit on the Internet challenges pupils to prepare short, two-minute speeches on an issue facing society. The pupils chose from three topics that connect the Internet and...

Students consider the role of climate change in the occurrence of vector born diseases such as malaria. In small groups, they research a specific vector to complete an information chart on climate changes in the region where the vector...

What happens when you combine 6.022 times 10 to the 23 piles of dirt into one? You make a mountain out of a mole hill. Scholars use dehydration to obtain percent composition and then calculate the molarity of the original...

Third graders explore the Internet to find the answers to the questions about the Sun, Earth, and the Earth's moon. They click on the links within the question to be sent to a website where answers can be found.

Bring your second, third, and fourth graders to the computer lab, or simply print this sheet! Now that you've reviewed complete sentences, fragments, and run-ons, it's quiz time! Your test-takers will complete the 10-question quiz by...

All types of energy are presented here, with neat pictures and labels to illustrate the technology typically used. Ways of harnessing the energy most efficiently are discussed, and good examples provide starters for further research....

Students demonstrate how to alphabetize animal names. In this word study lesson, students identify animals that live on the farm and conduct a favorite farm animal survey. Students order animal pictures in alphabetical order.

Cover one-point perspective through observation and practice. Class members examine several works of art that use one-point perspective, look at magazine images to find the vanishing points and horizon lines, and draw their own city...

Make a study of perspective in the real world. Learners examine and discuss works of art that show examples of perspective before trying their own hands at it. Using a grid drawn on transparent paper, class members transfer a view from a...

Experiment with light and shadow with a photography lesson. Learners first view several artistic photographs. They then play with different levels of light and various objects, eventually putting together compositions and taking pictures...

Students explore the strength of intermolecular attractions. They make slime and compare the difference in the physical properties of sheet and powdered polyvinyl alcohol with polyvinyl acetate.

Students are introduced to how the differences in solubility of materials are used in the manufacture of fibers and films. They are also introduced to the various processes used to make films and fibers. Pupils prepare fibers using wet...

Students participate in lab activities in which they examine immersion, stain resistance, and stress cracking of synthetic polymers. Students use their collected data to discuss service applications and possible performance of materials.
