Let the games grow. Groups play a card game to grow cells. Players start growing cells from stem cells to create specialized cells in the human body. Learners use full-grown cells from the human body to create stem cells in the lab to...

How close are we to a cure for diabetes? It seems the cure which has a connection to stem cell research is a possibility! Learners explore the concept of stem cells with an engaging hands-on activity. A PowerPoint presentation provides...

A cell of another color is still a cell. Pupils color a cell to identify its structures in the fourth segment of a seven-segment series. Groups work together to build a three-dimensional cell membrane segment, which is combined with...

What a bright idea! Young scientists conduct an experiment on flowers to finish the last of a six-lesson unit on Cells. Putting the stems into dye-injected water and leaving it overnight results in flowers that glow. This is to simulate...

The Fantastic Voyage is becoming close to reality. The class reads an article on the use of nanotechnology in the medical field and participate in a discussion about what they read. The discussion method helps class members become more...

Winogradsky columns are ideal for observing the role of bacteria and other microorganisms in an ecosystem. This student activity guide is complete with data tables for observations and analysis questions for processing what was observed....

Young botanists examine the different parts of tress and then draw parallels between the functions of these parts and the function of parts of the human body. 

It's all about the scale—they're not just wires, they're nanowires! The second lesson of the series builds on the oxidation-reduction experiment in the first lesson. Scholars synthesize a sample of nanowires using electrolysis. As they...

Student teams learn about engineering design of green fluorescent proteins (GFPs) and their use in medical research, including stem cell research. They simulate the use of GFPs by adding fluorescent dye to water and letting a flower or...

Students color-code a schematic of a cell and its cell membrane structures. Then they complete the "Build-a-Membrane" activity found at http://learn.genetics.utah.edu. This reinforces their understanding of the structure and function of...

[Free Registration/Login Required] An informational text about a young man who donated stem cells through a blood donation to help save the life of a cancer patient. A question sheet is available to help students build skills in reading...

Students set up a simple way to indirectly observe and quantify the amount of respiration occurring in yeast-molasses cultures. Each student adds a small amount of baking yeast to a test tube filled with diluted molasses. A second,...

The miracle of life is featured in this wonderful series of short videos and journal entries. A variety of topics are covered in this well written, authoritative piece.

Students culture cells in order to find out which type of surfactant (in this case, soap) is best at removing bacteria. Groups culture cells from unwashed hands and add regular bar soap, regular liquid soap, anti-bacterial soap,...

In this hands-on activity, students build their own two-cell battery. They also determine which electrolyte solution is best suited for making a battery.

The final activity of this unit, which integrates the Keepers of the Gate unit through the Go Public challenge, involves students taking part in experimental design. They design a lab that answers the challenge question: "You are...

In this lesson students learn about the circulatory system and how it relates to engineering. Then in a hands-on activity they create a model of blood. Students also act out cholesterol in a blocked artery and look at blood cell in a...

Students compare and contrast passive and active transport by playing a game to model this phenomenon. Movement through cell membranes is also modeled, as well as the structure and movement typical of the fluid mosaic model of the cell...

Students learn about how a device made with dye from a plant, specifically cherries, blackberries, raspberries and/or black currents, can be used to convert light energy into electrical energy. They do this by building their own organic...

Students set up and run the experiments they designed in the lesson Population Growth in Yeasts, using simple yeast-molasses cultures in test tubes. Population growth is indicated by the amount of respiration occurring in the cultures,...

Web-based activity provides an opportunity for students to study cellular respiration in an up-close and personal way. By following atoms and molecules through an interactive animation, they will be able to see the changes that take...

Students use a simple pH indicator to measure how much CO2 is produced during respiration, at rest and after exercising. They begin by comparing some common household solutions in order to determine the color change of the indicator....

This lab exercise exposes students to a potentially new alternative energy source-hydrogen gas. Student teams are given a hydrogen generator and an oxygen generator. They balance the chemical equation for the combustion of hydrogen gas...

Students find equations, which best-fit the data, using different regression models built into their calculators. The best method of handling this data, is to break the data into sections and fit different periods of time with different...
