Ninth graders explain how a scanning tunneling microscope works. In this chemistry lesson, 9th graders construct atomic models and simulate how their images appear under the STM. They discuss the limitations of their atomic model.

Students investigate plant cells. In this multiple intelligences lesson, students engage in a variety of activities to foster an understanding of plant cells and how they work. Students read, write, observe, and role-play parts and...

Students explore different activities in biology, physics and chemistry. In this science instructional activity, students examine chromosomes using a microscope and explain their significance in sustaining life on Earth. They investigate...

Learners use the macro mode of the OLYMPUS FE-140 CAMERAS as virtual microscopes to explore different habitats, observe plants, soil, and insects and other creatures. They download those images on electronic files and build web pages....

Young scholars study living and non-living materials that are found in soil. They study the things required by plants and animals to remain healthy. They design a collage of sand, stones, leaves and other natural items.

Students investigate the concept of seeds and how they can germinate. They obtain seeds and isolate them in a rubber glove before transplanting them into the ground. The lesson includes a graphic organizer for observations or information.

Students observe different animals with bilateral symmetry. In this biology lesson, students compare how these animals move. They discuss the evolutionary history of observed animals.

Students explain how cells reproduce. In this biology lesson, students explain the different stages of the cell cycle. They calculate the number of new cells produced.

Students explain the concepts of what DNA is and where it is located in a cell, identify the two types of molecules that make up the rungs of a DNA molecule and identify the two types of Purine and Pyrimidine molecules

Students describe how igneous rocks are formed, design a classification system to group igneous rocks and develop a controlled experiment to prove that the rate of cooling affects the size of the crystals.

Students discuss the impact of certain inventions. In this technology activity, students research Thomas Edison and the light bulb on the Internet and discuss how the invention impacted society. Students create their own simple inventions.

Students compare cell structure to the structure of a city. In this cell structure lesson, students investigate differences and similarities between cell structure and city structure. Students create a 3-dimensional, edible model of a cell.

Students view satellite pictures of the ocean, and discuss the presence of phytoplankton and the colors of the ocean. Students compare/contrast ocean satellite images with maps and globes, then color world maps to replicate the satellite...

Learners create simple 2D concept driven visualizations of cells and cell organelles and organize them into an effective presentation.

Students make the most of the season's first snowfall with a snowflake study. They create original snowflakes from paper, collect authentic snowflakes on paper, and examine and compare the snowflakes.

Students make a mold using Plaster of Paris and then make a cast using that same mold. They pick a fossil and describe how it looks. They write a fictionalized story about its life, or burial. (

Learners identify what plants need to grow. In this plant biology lesson, students analyze the differences between an artificial plant and a live plant. Learners plant seeds and discuss what plants need to grow. Students observe the...

Students isolate DNA from different food sources. In this biology lesson, students research DNA extraction. They analyze DNA stands collected from the lab, and compare the differences between each.

Students investigate ecological systems and the multiple uses of the environment by studying the osprey population.
