Investigating Factors Affecting the Heart Rate of Daphnia
What variables change heart rate? Young scientists observe the beating heart in Daphnia to understand these variables. They make changes in temperature, chemicals, and other factors as they graph the heart rates. Analysis questions help...

Signs of Change: Tree Rings
Young scholars identify and experiment with dendrochronology (the study of tree rings to answer ecological questions about the recent past) and come up with conclusions as to what possible climatic conditions might affect tree growth in...

The Grass is Always Greener
Third graders experiment with common grass and cellular division.
Curated OER
Does a change in pH affect the growth and survival rate of aquatic plants?
Students determine if changes in pH affect the growth and survival rates of aquatic plants. They evaluate the optimal pH levels for the growth of aquatic plants.
Curated OER
Temperature and Brine Shrimp Eggs
Pupils determine the optimal temperature at which brine shrimp eggs hatch and develop. They evaluate the changes, if any, which occur in a brine shrimp culture at various temperatures.
Curated OER
Habitat Assessment
Third graders demonstrate the effects of varying environmental components on plants and animals: chemical, physical and biological characteristics of a habitat. They find chemical, physical and biological characteristics of the lake at...
Curated OER
DOES A FLUCTUATION IN TEMPERATURE IFFECT THE GROWTH AND SURVIVAL RATE OF AQUATIC PLANTS?
Students determine if different temperatures effect the growth and survival rates of aquatic plants and evaluate the optimal temperature for the growth of aquatic plants.
Curated OER
Elastic Recoil in Arteries and Veins
A lab in which high schoolers examine the difference between arteries and veins. Budding biologists will find out which blood vessel can stretch furthest, recording their data in a table then answering several questions evaluating their...

Making the Impossible, Possible
With budget cuts galore, skip the bake sales and create a project with Donors Choose.
Curated OER
pH Change and Brine Shrimp eggs
Students determine if brine shrimp eggs hatch and develop more readily in an environment which has an acid or a basic pH. They evaluate the pH level which is optimal for the hatching and development of brine
shrimp.
Curated OER
How Clean Is Our Water?
Students examine samples of water to determine its cleanliness. They visit a waste treatment plant and/or reservoir. Students explore what protects the water supply from contamination by chemical or organize pollution. They trace the...
Curated OER
Microworlds in Waterways Around You Home
Students explore the concept that different waterways support different organisms. After completing experiments, students predict what life-forms exist in each waterway in their area. They research how humans impact the habitat of other...
Curated OER
Our Changing Voices
Twelfth graders examine their role in society. They search primary documents and assemble a family album.
Curated OER
Testing Termites to Discover
Students design an experiment to discover how termites respond to their environment.
Curated OER
Soil Organisms
Pupils work together to collect soil samples from different locations. In the samples, they identify the macroorganisms and classify them. They identify the conditions that affect how macroorganisms grow. They also analyze and identify...
Curated OER
Cell Repair and Cell Cycle
Seventh graders explore the cell cycle. They view pictures of different stages of mitosis and explain why cells reproduce. They identify the five phases of mitosis: interphase, prophase, metaphase, anaphase, and telophase.
Curated OER
Discovering the Oasis
Fourth graders investigate riverbanks and oxbox ecosystem at the Truckee River. They observe the plants, animals, insects and water organisms located there. Students document water samples, flow and then categorize them in class. This...
Curated OER
Dirty Pictures
Students investigate how food, clothing and shelter come from soil after they examine soil from their own backyards. They map soils on the color wheel before making glue and soil pictures and tie-dying T-shirts in red soil.
Curated OER
Mineral or Maceral Mosaic
Learners study about geologists and their job. They also study that rocks are made up of minerals and organic material by conducting an experiment where they create their own "granite" or "coal".
Curated OER
The Cell: Unit of Life
Pupils identify the parts of plant and animal cells, how samples can be obtained and what the differences are.
Curated OER
Cells And Their Parts
High schoolers investigate different types and their parts. They differentiate prokaryote and eukaryote cells and create a venn diagram displaying differences or similarities. Students write ten similes related to the cells and parts of...
Curated OER
Seeing the Cell as a System
Students explain how the components of a cell operate as a system. Students examine a bicycle and find out if parts were arranged differently, could the system still be carried out. They look at cells as well and see what function they...
Curated OER
Parts of the Cell
Students examine plant and animal cells to observe the organelles present in the cell, to match the function of each to the organelle on a cell model and to build a model of the plant or animal cell.
Curated OER
Protecting the Environment
Students explain what biodegradable materials are and list examples of them. They design, with online partners' feedback and input, a product made of biodegradable materials and develop a marketing campaign to best sell their product.
