The Power of One - Math in a Different Angle
In this 2-day lesson focused on exponents, middle schoolers will cross the curriculum by engaging in science, history and language arts activities. Exponential growth will be explored using grains of rice on a chess board. Exponential...

Population Dynamics
Will human population growth always be exponential, or will we find a limiting factor we can't avoid? Young scientists learn about both exponential and logistic growth models in various animal populations. They use case studies to...

Common and Natural Logarithms and Solving Equations
Log some practice with logarithms. A PowerPoint presentation provides a tutorial on the change of base formula involving natural logarithms and solving exponential equations with logarithms in the fourth installment of a seven-part...
Curated OER
Scientific Notation III: Linear vs Exponential
Students examine the differences in exponential growth and linear growth of a system. They interpret data on graphs and develop their own charts. They answer discussion questions as well.
Curated OER
Introduction to Graphical Representation of Data Sets in Connection to Cellular Growth
Students practice graphing relationships between variables by studying topics such as exponential growth and decay. They conduct a series of numerical experiments using a computer model and a variety of physical experiments using mold,...
Curated OER
Aquaculture: Down on the Salmon Farm
Students examine the problems of the continued development of aquaculture. They also brainstorm ideas that people in this field would need to be successful.
Curated OER
Population Explosion Relay
Learners study the concepts of seed dispersal, germination rate, exponential population growth, and predation by engaging in a bean 'weeds vs. natives' relay race. They illustrate how weeds out-compete other plants for space by crowding...
Curated OER
Graphing the Population Explosion of Weeds
Learners are introduced to the seed cycle and draw the specific steps. In groups, they identify the human barriers to the spreading of weeds. After calculating the rate of spreading of the Yellowstar Thistle, they create graphs to see a...
Curated OER
Introduction to Graphical Representation of Data Sets in Connection with Nuclear Decay
Students record data, make observations, and share in experimentation and discussion of numerical experiments.
