In this surveys and samples worksheet, learners discover data collection techniques and write their own survey questions. Students use random sampling, convenience sampling, and systemic sampling and analyze their results.

What can layers of rock teach us about the climate? Young scientists solve a mystery about who stole a cookie by applying the law of superposition. Then, they apply the same concept to solve a more difficult mystery, trying to determine...

Students explore different methods of taking surveys and conducting polls and examine these methods for bias. They design and administer a sample survey, analyze the data and present their findings to the class.

Students discover that proteins that are the product of DNA translation are different for different species. They determine that by analyzing their mass and charge they can differentiate between two different species. They use some of...

The relationships within and between ecosystems can be explored. after examining an area for living and non-living things students complete the same examination in the forest ecosystem. Students identify abiotic and biotic elements in an...

Students are presented with the question, "Do plants that grow underwater use oxygen?" They create an experiment to test the presence of dissolved oxygen in the water using provided materials. Student experiments include a control jar as...

Sea ice contains 17 sub-types based on age and various characteristics. Scholars observe ice floating in a simulated ocean and record their observations. Then, they view photographs of different types of sea ice and learn to...

How many people really recycle recyclables and how do they feel about it? High schoolers create a survey to find out. Once they agree on what questions to include, they each interview four people outside of the classroom....

Young scholars locate an area of marsh and, by measuring the total number of individual plants in a sample area, determine whether purple loosestrife population density is correlated to the total plant diversity of the community. They...

Students recognize whether one wants to drink water, swim in it, or for the health of the organisms living in it. They prepare different water samples to observe and collect samples regarding the water quality.

Students are shown how temperature affects dissolved oxygen and they create a graph showing this relationship. They think about the adaptations of animals to live in different water temperatures. Students test four different water...

High schoolers are taught that invasive plant removal can have a variety of impacts. They are shown this by using graphs. Students view maps of vegetation change on Iona Island. They discuss implications of changes on marsh birds using...

Less than one percent of the water on Earth is usable in people's homes. As pupils consider this fact, they reflect on their own water usage before designing a survey to collect information on water usage by others. They then analyze...

High schoolers examine the factors that affect the accuracy of opinion surveys. They calculate probability and chance using data they have collected. They practice reading tables and graphs as well.

Students survey and dissect as many fish as possible. They count nematodes, cestodes and crustaceans on the fish, fill out autopsy reports, and transfer data to a chalkboard data table. Students graph the results of the entire class...

Learners investigate the human impact on coastal land. In this coastal surveys lesson plan, students choose a coastal area and complete a survey sheet about the area. They choose a topic about a sea side village called Dunwich to prepare...

Eleventh graders practice the Quadrat Survey Technique to analyze the biodiversity of a local plant community. They compare its biodiversity with the documented changes in biodiversity of the tallgrass prairie over time.

In this cells worksheet students answer questions regarding the characteristics of living organisms observed during a pond water survey.  Students draw diagrams of a food chain. 

They say elephants never forget—and your class won't forget an insightful modeling activity either! Junior zoologists take part in a mock elephant census using the sample count and total count methods. The included materials provide...

How do we count the fish in the ocean? An engaging lesson models how to estimate fish populations with observational surveys. Class members begin by studying the behavior of fish on the coral reef in the oceans. They...

Students identify and describe various organisms living in a pond water environment. They describe the characteristics of living things. Students compare and contrast organisms created by asexual reproduction and sexual reproduction....

In this biology worksheet, students identify and define the vocabulary terms listed and make a prediction about the outcomes of the experiment. Then they complete the chart of the observations of the plankton diversity in drops of pond...

Students explore energy by categorizing rocks. In this British Columbia geology lesson, students define many different vocabulary terms associated with mining such as sedimentary, igneous, and metamorphic. Students utilize sample rock...

Learners pan for minerals in a stream and discover why magnets attract magenitite but not nonmagnetic grains. They participate in the actual panning process and bag samples to be examined in class. Students recognize minerals by color...
