Students explain how an agarose gel is poured and DNA is loaded into the wells of the gel. They practice the technique of pouring and loading an agarose gel and participate in a teacher demonstration.

In this acid-base reaction instructional activity, learners calculate the ion concentration and pH for 6 solutions, graph titration results for 11 reactions and use Henderson-Hasselbach equations for three problems.

In this fluids, electrolytes, and acid-bas balance system study questions, students define 12 words associated with this system. They answer 12 short answer questions about the components of the acid-balance system.

In this digestive system worksheet, students answer 9 questions, 2 of which are multiple choice and 7 are short answer. Included are questions about the process of digestion and the structures of the digestive system.

Students examine wetlands and what the effects of destroying them will do.  In this wetland instructional activity students relate the importance of wetland functions to their own needs. 

Students extract the DNA from a strawberry. In this DNA technology lesson, students describe what they think DNA looks like. They use a procedure to isolate and extract the DNA from a strawberry.

High schoolers compare different DNA and run a gel electrophoresis.  In this DNA lesson students complete a DNA activity that allows them to better understand its structure and function. 

Students applied various mathematical analyses to interpret their data. By using the resulting DNA fragment patterns from several enzymes students established a possible evolutionary relationship among the mice.

Students demonstrate how water quality and environmental health issues can be analyzed together, how hydrologic information can be built up, and how decisions can be made using GIS.

Students perform an experiment to extract and observe DNA from plant Tissue. They read about the procedure and relate it to the procedure used to isolate DNA from an endangered plant species. This is lesson three in a nine lesson unit...

For this acids and bases worksheet, students determine the pH and pOH for a given solution. Students determine the conjugate acids for the given species. Students calculate which solution will have a higher pH. This worksheet has 16...

Students study the basic function of DNA and then extract it from strawberries. In this DNA extraction lesson students examine DNA and see why the extraction of it is so important to scientists. 

Students use stream trays covered in different types of rocks or soil to investigate infiltrates and runoff. In this water pollution lesson, students work in groups with stream trays that have different substrates. They write a paragraph...

Students explain the processes for separating DNA from tissue and separating complex mixtures.  In this exploratory lesson plan students complete a lab where they extract DNA.  

Learners examine different mixtures and how they can be separated.  In this electric sieve lesson students complete an activity that allows them to separate mixtures.

In this trees and plants of the wetlands worksheet, students click on the links in the questions about trees and plants to find the answers to the questions and then come back and answer the questions. Students answer 27 questions total.

Students study the Mississippi Rover and how it has changed over time.  In this environment lesson students research and summarize things about the ecosystem of the river. 

Students define the term acid rain, and the causes of acid rain. They locate regions where acid rain is most affected, and what can students deduce from maps of geology and soils in New York State. Students answer the questions why are...

High schoolers examine the life cycle of c-ferns. They complete experiments on the organisms exposing them to differnet amount of UV radiation. They collect data and analyze their results.

Students perform an experiment in which they extract DNA samples from hair samples. They follow a set procedure to extract the DNA and complete summary questions.

Students examine the positive benefits and negative consequences of genetically modified organisms following a lecture covering key biotech concepts and techniques. Students then conduct and experiment comparing the travel rate of...

Students create wetland models in pans and use them to experiment to see how plants help slow the flow of runoff water and keep our waterways clean.

Learners explore electrophoresis, a technique used to isolate DNA. They assemble a gel chamber for separating mixtures. Students observe separation influenced by electric charge. They define separation through gel electrophoresis.

In this kidneys instructional activity, students review the function of the kidneys including what happens when the kidneys stop working. Students also compare kidney function in fish, frogs, and kangaroo rats. This instructional...
