Welcome to Martha's STEM Stories! STEM stands for science, technology, engineering, and mathematics. You may already know that doing STEM means testing ideas, collecting data, making calculations, and drawing graphs and charts-but you...

In addition to defining adult stem cells, this resource examines where they are found, what they normally do, and what tests are used for identifying adult stem cells.

Learn the basics of stem cells by reading the article and watching the stem cell animation. Stem cells as therapy for diseases is the perspective of this website. Somatic cell nuclear transfer is covered.

Discover what stem cells are and where they come from in this informative article from Medical News Today. Learn how they are classified and identified, new advances in stem cell research, and what the legal issues are.

This video explores the basic scientific and ethical questions surrounding the use of stem cells in medical research.

This essay from NOVA: "Life's Greatest Miracle" explores the debate over the use of embryonic stem cells in scientific research.

Building STEM centers that foster creativity doesn't have to be complicated. All you need is a smart layout that provides designated areas stocked with a wide variety of everyday materials. Here are seven easy STEM centers to include in...

Practice questions over induced stem cells from healthy adults.

Understand why stem cells are sought after for healing human diseases through cell-based therapies in this article and its supporting resources.

Explains how to create a stem-and-leaf plot from a data set. Demonstrates how to format a clear stem-and-leaf plot.

A stem and leaf plot is a graphical representation for investigating variation. You will convert an ordered stem and leaf display grouped by tens into an ordered display grouped by fives.

[Free Registration/Login may be required to access all resource tools.] Make and interpret stem-and-leaf plots and histograms for a set of data.

The students will be using discovery techniques to learn about stem and leaf plots.

This site is a question/response page which focuses on stem-and-leaf representation and how to construct scatter plots. Dr. Math works through an example and gives commentary notes. Site also contains links for more help.

Stem cells are unspecialized, stems cells are capable of dividing and renewing themselves for long periods, and stem cells can give rise to specialized cells.

What stages of early embryonic development are important for generating embryonic stem cells? How are embryonic stem cells grown in the laboratory? What laboratory tests are used to identify embryonic stem cells? Article addresses these...

Stem cells found in the bone marrow are crucial for our health because they are needed to become new blood cells that sustain and protect our bodies. But when the transformation goes wrong, harmful mutations can cause the cells to start...

In this lesson, students will compare water from a fresh lake to water from the Great Salt Lake to begin to build a conceptual model for how salt dissolves in water. The lesson focuses on students using and developing models of molecules...

A nice explanation of a stem and leaf plot, accompanied by many helpful examples.

Young scholars can explore the engineering design process while watching video excerpts from Curious George and participating in hands on activities.

An hands-on lesson where young scholars create a wind powered boat with their knowledge of reusing, recycling of materials, and wind power.

Explore how different objects move down ramps in this Curious George lesson. Students will make predictions about how objects will roll down different heights of ramps.

A lesson plan for students to explore a mystery object by using their five senses. Includes procedure to conduct lesson.

Martha's True Stories consists of non-fiction texts with accompanying video, glossary, and quiz centered on four STEM topics: science - the environment; technology - communication, transportation & tools; engineering - inventions;...
