If you don't want to drink red cabbage juice, here's another use for it—a decoder! Using vinegar and ammonia-based window cleaning liquids as invisible inks, scholars create designs in the second lesson of the series. Red cabbage juice...

De-icing materials may have a harmful effect on our environment; have your class perform an experiment to test the nature of these effects. Scholars monitor the survival rate of a sample of daphnia as the concentration of a de-icing...

Learners study the weather phenomenon El Nino is and what causes it, and recognize how remote sensing technology can detect and predict El Nino. Students discover how El Nino affects weather conditions throughout the globe through research.

Learners study the characteristics of wetlands. They are introduced to terms and different examples of wetlands. The hands-on activity reinforces the different parts of the wetlands, and provides a working model of a wetland.

Ecology aces examine sea surface temperature maps and relate temperatures to concentration in fish and zooplankton populations. Take your class to a computer lab and provide experience with actual remote sensing data. Some of the links...

Students discover that material and energy uses by a city come from outside the city boundaries. They realize that the pathway of these material is linear instead of cyclical as they are in natural ecosystems.

Students discuss ecosystems, eliciting their current knowledge of an ecosystem. Students receive an Ecosystems document and look at the picture. Students brainstorm connection between the cover picture and ecosystems. The indicated...

Young geologists become familiar with the Karst Topography in the Ozark Mountains. They study how human activity has affected the cave ecosystem. They conduct a simulation in which a large development is proposed in the area, and they...

Young scholars investigate Earth and its resources. In this Earth, space, and nature lesson plan, students collaborate to design presentations on the Earth, its cycles, and how humans have impacted the planet. Images, diagrams, and...

Germination is an amazing process that results in amazing things. The book The Tiny Seed is the inspiration for a set of activities that will help build early literacy, observation, language, and writing skills. The class observes how...

Scientists use ice core samples to obtain temperatures of the earth from 400,000 years ago! The third of five lessons instructs pupils to interpret historical climate data to see changes over time. In part I, participants interpret...

We all know someone who won't eat the banana with a brown spot, the grape with a dimple, and the apple with a bruise. Scholars use different fruits to explore what happens when fruits really start to decompose. They set up an experiment...

Second graders investigate the diversity of plants and animals in a rainforest. They watch an online story developed by the Rainforest Alliance, observe and record animals in their local area, explore various websites, and compare and...

Students use tools to represent bird beaks and pick up different types of food with them in order to discover which beak would help the bird survive depending on their food type.

Why does it get so hot inside of our cars in the summertime? The greenhouse effect! Lab groups experiment to see what happens to an ice cube enclosed in a jar and placed in sunlight as compared to an ice cube outside of the jar. They...

Learners identify various aquatic wildlife species. In this biology lesson students collect clues about animals that live in wetland habitats. Learners rotate through several stations displaying particular animal species to collect their...

Students explore botany by completing KWL worksheets. In this seed transportation lesson, students define a list of vocabulary terms associated with botany and seedlings before completing worksheets based on assigned text. Students...

If you need a comprehensive review of the development of Earth's atmosphere through the ages, then this is for you! The presentation starts with a introduction to theories of planet formation and initial distribution of isotopes in the...

In 2003, there was an unprecedented decline in the population of Blue Mud Shrimp up in Oregon. This presentation gives many of the facts, and theories that were developed as to why the population took such a dive. Excellent photographs...

Here is a series of questions intended to get kids thinking about what they need, what they have, what they like, and how the overall environment is changed when art is added. They consider the impact of sculptural art in their community...

Why is diversity in biology so important for an ecosystem? Explore biodiversity, evolution, and natural selection with a presentation for your biology class. It features clear information, activities for further understanding, and...

Some like it hot! Scholars observe both exothermic and endothermic reactions as part of the carbon dioxide oxygen cycle. First, scientists demonstrate (or watch) a chemical reaction to create pure oxygen using fire for...

Kids act as scientists and preditors in this short natural selection activity; they collect and analyze data, then apply their new knowledge to real-world examples of natural selection. The layout of the worksheet is easy enough to use...

When Captain John Smith visited the Chesapeake Bay in the summer of 1608, what types of animals and habitats did he encounter? Your young historians will analyze primary source documents to answer this question, as well as compare...
