Estimating Fish Populations

Will all the people be able to fit? Using historical population growth rates for continents, pupils determine estimates for the future population. The second day, pupils investigate whether a linear, quadratic, or exponential function...

These aren't models made of clay. Young mathematicians model given population data using exponential functions. They consider different models and choose the best one.

Lead young scientists on an investigation of fishery practices with the final installment of this four-part unit. Using a PowerPoint presentation and hands-on simulation, this lesson engages children in learning how fish populations are...

Do you know how the population has grown of your community? Can you predict the population over the next half century? Can we find an algebraic model that matches our data? These along with many more questions can be researched by young...

Congratulations, you've just hit the word problem jackpot! Covering an incredible range of topics from integers and fractions, to percents, geometry, and much more, this collection of worksheets will keep young mathematicians busy...

How many of the pupils at your school think selling soda would be a good idea? Show learners how to develop a study to answer questions like these! The lesson explores the meaning of a population versus a sample and how to interpret the...

Students complete an activity designed to demonstrate how scientists estimate total population numbers of organisms in the wild. They discuss overpopulation and the biotic and abiotic factors that affect population growth.

What is the typical length of a yellow perch? Pupils analyze a histogram of lengths for a sample of yellow perch from the Great Lakes. They determine which measures of center and variability are best to use based upon the shape of the...

Looking for an estimation activity a bit more involved than the typical "guess the number of jellybeans in the jar" game? Here, learners use a picture to estimate the number of people at a large event, look for potential problems with...

Pike fish pose a threat to native trout and catfish in lakes. Would you drain and poison a lake to get rid of the Pike fish? If the lake was drained and poisoned, then refilled and repopulated with trout and catfish, how would you...
