This student activity engages the students' thinking by listening to a story, brainstorming ideas in small groups about how human activity or natural disasters could possibly impact an animal's environment, and then reinforcing that thinking using a board game called Save an Animal.

Use a virtual scanning tunneling microscope (STM) to observe electron behavior in an atomic-scale world. Walk through the principles of this technology step-by-step. First learn how the STM works. Then try it yourself! Use a virtual STM to manipulate individual atoms by scanning for, picking up, and moving electrons. Finally, explore the advantages and disadvantages of the two modes of an STM: the constant-height mode and the constant-current mode.

This lesson is a classroom and field-based activity where students learn about the parts of a flower through observation, journaling, and Observation.

This activity is a field-based investigation involving identifying and investigating common trees on the schoolyard and creating a field guide containing pressed leaves.

This article highlights science lessons about mammals, mammal diversity and adaptations, and polar mammals. Literacy integrations and alignment to national standards are included.

Students use data acquisition equipment to learn about force and displacement in regard to simple and complex machines. In the engineering world, materials and systems are tested by applying forces and measuring the resulting displacements. The relationship between the force applied on a material, and its resulting displacement, is a distinct property of the material, which is measured in order to evaluate the material for correct use in structures and machines.

This activity is a lab investigation where students gather data which compares 2 types of bubble gum, while learning to use the scientific method to collect qualitative and quantitative data using SI units.

This activity is to dispel the misconception that there is one single structured scientific method used by all scientists, and tackle some ethical issues raised in life. This is accomplished using the popular movie "Awakenings" and student observations and reflections.

This activity is a classroom and field activity where students learn about and practice scientific observations in the classroom and then complete a field activity by making and recording scientific observations on school grounds.

This video from Thinkport introduces the seahorse, an unusual, endangered fish that has puzzled scientists who are attempting to save it.

An active problem-based assignment that uses the Genbank database to teach the basics of molecular biology and molecular evolution

This activity is a year long project observing the changes in a specific tree. It includes using all the senses in the observation and making two different booklets to record what we observe. It also includes several picture story books that enhance the lesson.

In this video segment adapted from the College of Menominee Nation, tribal members share examples of how seasons are changing, and how these changes are affecting local plants.

This activity is a lab investigation where students gather data on a seed or seeds that have been planted per their own design.

In this lesson, based on the documentary Through My Eyes: The Charlie Kelman Story, students learn about the history and state-of-the-art of one of the world's most commonly performed surgical procedures--eye cataract removal and replacement.

Semiconductors are the materials that make modern electronics work. Learn about the basic properties of intrinsic and extrinsic or 'doped' semiconductors with several visualizations. Turn a silicon crystal into an insulator or a conductor, create a depletion region between semiconductors, and explore probability waves of an electron in this interactive activity.

This article provides a list of children's literature relating to the geography and characteristics of the Arctic and Antarctica.

This video segment adapted from Northwest Indian College reveals how Native American life and knowledge is connected to natural cycles.

This is an activity in which students use their senses to describe their garden. This is a guided inquiry lesson.

Spreadsheets Across the Curriculum module. Students build spreadsheets to calculate and compare bacterial population sizes from lab cultures in antibiotic-free and antibiotic-containing media.
