As an example of nature's water filtering system, young ecologists conduct an experiment in the lab. They construct a funnel out of a plastic bottle, fill it with specified layers of materials that simulate layers of soil, then run muddy...

Learners experiment with making a water filtration system. In this engineering lesson, students get into groups and are challenged to use only eight items to create a water filter. When finished, learners compare and contrast their results.

Students make coffee filter eggs. In this art activity, students cut coffee filters into egg shapes. Food coloring is added to water and students drop the colors onto the eggs using a eyedropper. Students allow the filters to dry and...

Students investigate our water system and how it is filtered. In this science instructional activity, students perform a laboratory activity to investigate the process that goes into filtering water. They relate this activity to other...

Youngsters develop an understanding of how smog is produced, and how exhaust from automobiles is one of the major sources of smog. They explore the roles that engineers play in developing technologies that reduce smog, then work in teams...

Students look at the data maps given to them about how chlorophyll affects the algae blooms and make predictions about the harm they will cause. In this data maps lesson plan, students manipulate data sets from the website.

Young learners are introduced to the history, and customs surrounding St. Patrick's Day. This colorful and enchanting lesson has the students hunt for leprechauns, four-leaf clovers, and that lucky pot 'o gold.

Tenth graders research about the different cell organelles. In this series of biology lessons, 10th graders compare two allotropes of carbon. They investigate how the rate of reaction is affected by concentration.

Students study a variety of global wetland habitats, their similarities and differences. They examine the variety of life that such wetlands support and determine that many animals and plants are adapted to life in wetlands, that...

Use Native American tradition to create the context for making different cultural representations of pottery. Practice using geometrical shapes painted on the pottery, research different patterns found on Native American pottery, and...

Students observe and identify the changes that occur in the life cycle of a butterfly. They view photos of each stage of the life cycle, create an art project of the butterfly cycle, and illustrate a book titled "The Life of a Butterfly."

First graders go on a leaf-hunting expedition around the schoolyard. They determine from which trees they fell using identification cards. Students read several books about leaves and apply their artistic skills by using the collected...

Learners discover the faults throughout the Earth. They describe the different types of faults and how they are related to earthquakes. They build models of the faults.

Students read and discuss the book about the butterfly and create their own butterflies using liquid watercolors and pipe cleaners. They then create a butterfly development book, included in the lesson, and color the pictures using...
