Estimating Fish Populations

Students explore features to consider when designing a scientific study. In this science research lesson, students examine different methods of data collection and consider which method would be appropriate for determining how many types...

Learners calculate the deer population using proportion. In this algebra lesson, students apply the concept of ratio and proportion to real life scenario.

In this estimation activity, students interpret given data and estimate fish populations. Students write a conclusion of their findings. Afterwards, they determine the probability of given events. This two-page activity contains...

Middle schoolers are introduced to a problem involving an environmental issue. They are introduced to the capture-recapture method which involves capturing fish, tagging them, returning them and recapturing another sample. Pupils work...

Students investigate common fishing methods used to capture sharks. They decide why these methods and the shark's reproductive biology are contributing to the quick reduction in the shark population.

Students keep a journal of all they places they have visited for two days, and how long each visit lasts. They participate in a mock fish tagging activity to determine how many fish are in a population and determine the mean, median and...

Students work collaboratively to determine how many crackers are in a large container. They then view a video to see how often people use estimation in their jobs, and another video to watch students work on figuring out appropriate...

Students use a similar method to the Lincoln Index to estimate a population size.

Eighth graders use goldfish crackers to simulate a capture-recapture method of data collection. They fill in a chart and determine the averages. They find the estimated population of fish and the actual population of fish based on the...

Seventh graders discuss water issues and its affect on salmon population. They recreate a sampling river with fish (cheddar) and scoop them to tag them (which means they exchange them for pretzel fish.) They complete a spreadsheet to...
