Population Density In Fish
Middle schoolers investigate how a population of fish multiplies in an ecosystem and the kinds of things that must be done to maintain a healthy population balance with other organisms that live there. They conduct an experiment to test...

Cold Hard Facts? What Inquiring Minds Will Know -- Inquiry-Based Ice Investigations
Learners are introduced to the concepts of perimter, diameter, circumference and measurements. In groups, they complete two worksheets in which they determine if the ice dimensions make a difference in the way it floats. They discuss...

Water Awareness Portfolio Instructions
Students participate in a water awareness portfolio. In this water conservation lesson students create a portfolio to help make them aware of current water conditions.
Curated OER
DNA Isolation
Students use scientific methods to investigate the concept of DNA. They observe the DNA of human cheek cells. This is done with the use of a lab experience. Students record their observations and reflect upon on how each organism is...

Effects of pH on Organic Molecules
Young scholars investigate the effects of an acid and a base on the structure of milk protein. They observe the changes to droplets of milk when adding ammonia and lemon juice and relate the changes to old, curdled milk. An extension...

Transformation of E. coli with Antibiotic Resistance
High schoolers participate in an experiment in which they transform an E. coli cell. They discover how the genetic make-up of the cell can be changed by added foreign DNA. They answer questions to complete the lab.
Curated OER
Struggle for Existence and Population Growth in Aphids
High schoolers examine the population of aphids. They identify adaptations they have made for their environment. They make predictions, test their hypothesis and collect information that either proves or disproves their theory.
Curated OER
Antibiotic Resistance in E. coli
Students discuss the antibiotic resistance of bacteria. They design an experiment to test the resistance of different strands of E. coli. They answer discussion questions to end the lesson plan.
Curated OER
Earthworm Movement and Landscape Structure
Students describe differences in animal usage of habitats depending upon successional status of site. They also design other experiments to test movement patterns of animals through habitats of differing structure.

pH Readings and Salinity Readings of Water From Three Locations Within the Neponset River Watershed
Sixth graders test the ph levels of water from three different water environments within the Neponset River Watershed. They discuss the three different water environments, take pH measurements of the three samples, and predict which...

SEPARATION OF A STARCH-GLUCOSE MIXTURE USING GEL FILTRATION
Students make a starch-glucose solution and pour it through gel in order to separate the starch from the glucose. They examine how starch is a larger molecule than glucose and test for the presence of these substances using other...
Curated OER
Water Quality
Students play the role of scientists testing for water quality in the area. In this ecology lesson, students determine the water sample's pH, temperature, dissolved oxygen and turbidity. They write a journal reflection after the activity.
Curated OER
Climate Analysis Using Planktonic Foraminifera
Students manipulate scientific data, plot the data and then interpret their results. They should recognize that the climate likely continue to change in the future. This activity ties in well with a discussion on current climate change.
Curated OER
A Watershed Monitoring Module
Students explore the relevance of water quality monitoring in relation to a local wetland ecosystem. They conduct standard water quality tests using wet tests and CBL calculators and probes. Student record and interpret the results.
