Students discover enzyme to substrate specificity. The experiment uses samples of glucose and lactose in combination with the enzyme lactase. Students observe the reaction between the lactose and the lactase; the lack of a reaction...

Student identify the characteristics of plants. Through hands-on demonstration, they create a model of plant parts. Learners differentiate between the major divisions of the plant kingdom with a particular emphasis on the vascular and...

Students model and differentiate between the processes of mitosis and meiosis. In partners, they use yarn and construction paper to create models for each of the phases of mitosis and meiosis then compare the chromosome numbers in each...

Students explore the field of genetics. They examine four basic traits. Students demonstrate their knowledge of phenotype and genotype by charting their personal traits. Students compelte a Meiosis chart. From the chart results,...

Young scholars investigate that chemicals may affect different people in different ways. They also realize that their perceptions of dangerous materials may not be realistic and that the news media may not provide all the information...

Students investigate the mechanics of an fMRI and the properties of neurons. In this biology instructional activity, students analyze the way the brain works by performing tests in the neurons in the brain. This is all done theoretically.

Students build plankton models and compete to see which sinks most slowly. They write, or orally present ,the adaptations they incorporated to slow the sinking rate of their organisms. Race results can be grounds for some prizes!

Fourth graders name colors of M&Ms and record answers. They estimate number of M&Ms of each color found in a typical package of M&Ms on piece of paper.They record information on sheet of paper and create a spreadsheet. paper.

A chart with eight rows makes up this handout. The columns are labeled with two graphs ("x vs. t" and "v vs. t"), a written description, and a motion map. One cell in each row is filled in, leaving the rest for your class to complete....

A complete overview of oxidation, reduction, and how electrons are moved in respiration. You could use this slide show to elaborate on the concept of harvesting stored energy, and to summarize the stages of aerobic and anaerobic metabolism.

Activate middle schoolers' minds with this physical science activity. Learners vary the diameter of gears and the number of teeth on them to find how energy output is affected. This writeup features well-developed background...

High schoolers explore the different fields of bioengineering. They will create and interpret graphs from cancel cells data. They then calculate the amount of drugs found in blood and eliminated by the body over time.

Lisa Peters presents macroevolution as a large-scale family tree in her book Our Family Tree: An Evolution Story. She suggests the process from single-celled organisms to modern-day humans, and learners explore new vocabulary...

Biotechnology changes lives every day, but how did it all start? Learn about Cohen and Boyer's technique for recombinant DNA and the founding of this new scientific study. Then, scholars use the online interactive to discover how Hanahan...

Ever wonder what drones are doing high above us in the sky? This article gives your class an insight to what those robots in the sky are doing. After reading an article on drone technology, pupils are prompted to respond to a...

Biology stars extract DNA samples from beef thymus and then examine its properties. They use enzymes to digest the DNA samples, and then use electrophoresis to separate fragments. Finally, they discuss methods and principles of...

Students examine how fuel cells and combustion engines work. Using the internet, they research the positives and negatives of the various energy sources. In groups, they complete an experiment with a working fuel cell model and take a...

High schoolers conduct lab test with minced onion to determine where chromosonal DNA is located within the cell, and whether or not it can be extracted.

Middle schoolers create their own experiment in which they have yeast cells growing in liquid environments. They examine the relationship between humans and microorganisms. They also practice using the scientific method.

Students investigate atomic and nuclear structure of matter by researching historical atomic theories. Students examine Rutherford's studies and discover that many scientific conclusions change over time as new data is collected.

Fifth graders study the circulatory system. In this circulatory system, 5th graders participate in five stations with different activities at each station. Students discuss their findings from each station.

Students are able to extract and observe a visible amount of DNA from Escherichia coli cells. They discuss the properties of DNA. Students confirm the presence of DNA by a reaction with an indicator.
