Students are introduced to the differences between acids and bases and how to use indicators, such as pH paper and red cabbage juice, to distinguish between them. They make predictions that can be answered through scientific...

Students use red and blue litmus paper to determine the category of common substances. They then set up an experiment using vinegar, water, and ammonia (or milk of magnesia) to determine that acids make the best solution for dyeing...

Determine the number of possible genetic codes. Class members are challenged to determine the number of possibilities of a genetic code that is 20 bases long. They continue to explore the average lengths of broken RNA molecules.

Middle schoolers have a bushel of fun as they engage in activities and research core facts about apples. Packed with suggestions for in-class activities and out-of-class research, the colorful 6-page packet is sure to satisfy hungry...

Students explore a series of activities on using BLAST. In this biology activity, students explain the significance of BLAST in DNA query. They give real world applications of BLAST.

Learners identify the different types of fractals. In this geometry lesson, students use math to analyze different biological phenomena. They collect data from the experiments and construct graphs.

Students applied various mathematical analyses to interpret their data. By using the resulting DNA fragment patterns from several enzymes students established a possible evolutionary relationship among the mice.

Students investigate the dangers of radiation by exploring recent nuclear tragedies.  In this scientific debate lesson, students define the idea of radiation "half life" and determine if low doses of radiation are truly damaging to...

Students apply measurement skills using the metric system. They explain the process of isolating DNA from other cell contents. They apply knowledge of cell structure to explain the process of isolating DNA.

Before graphing and finding distances, learners investigate the coordinate plane and look at patterns related to plotted points. Points are plotted and the goal is to look at the horizontal and vertical distances between coordinates and...

Math really is just one big puzzle waiting to be solved. Show learners that math can be intriguing and provide them with visually engaging problems and puzzles. The focus is on solving simple equations and looking at expressions. 

Students see how an infectious disease such as AIDS may be quickly transmitted throughout a population. They conduct a simulated transmission of an infectious disease and mathematically determine the number of possible infected individuals.

Students analyze data taken from proteomic experiments. In this biology lesson, students explain the importance of bioinformatics tools in the study of proteins. They evaluate scientific results using math and computer software.

Students access prior knowledge of solar energy and understand that solar energy produces heat. In this solar cooker lesson, students complete grade appropriate experiments using the heat of the sun. Students complete a worksheet on...

Fourth graders are involved in a lab experience to look at the concept of heating up various materials to see how they react to an increase in temperature. They make observations and record them in a lab journal. Then students discuss...

Students consider the role of industry on the American landscape from a variety of perspectives. They investigate a simulated case study. They investigate a chemical spill catastrophe. Students write an informative pamphlet to assist...

In this activity, Students can use a pH sensor to record pH versus base volume data for an acid base titration. They will manually model the curve using a logistic function.
