Students isolate and determine the amount of plasticizer in polyvinyl chloride. They use Infrared Spectroscopy (IR) or Fourier Transform Infrared Spectroscopy (FTIR) and gravimetric techniques in this experiment.

Students design an investigation using yeast. In this environmental engineering lesson, students design an investigation to determine how environmental factors affect the growth of yeast. They will collect quantitative data and discuss...

Here is a well-designed lesson on biodiversity that should intrigue your charges. In it, pupils compare a natural desert area to a school field to see how habitat destruction affects species diversity. Groups set up transects and collect...

Students explore the concept of probability.  In this probability lesson, students use area to determine probability.  Students use charts and spinners to help determine the probability of events such as flipping a coin or...

Students examine carbon output. In this climate change lesson, students plan and complete an assessment of local businesses and schools based on the carbon output of their electrical usage.

Here's a five-star lesson plan in which inquisitors conduct sophisticated experimentation with cellular respiration in plant seeds. Placing seeds in a closed system they measure the amount carbon dioxide produced and relate it to...

Scholars investigate levels of nitrogen dioxide in the Pacific Northwest by examining the role of nitrogen in air pollution and how remote sensing can be used to measure nitrogen levels. An Excel spreadsheet calculates the difference...

Learners determine how scientists measure pollutants in food and the environment. Students discover how scientists remove one material based on its physical properties. Learners figure out how much of a pollutant is present after...

Young scholars compare the population of insects in different microclimates. For this biology lesson, students collect data using probes to tabulate temperature and soil data. They predict how certain parameters change as an area...

Students investigate the impacts of major rainfall and subsequent runoff on turbidity in lakes. They, in groups, develop a presentation of their research and/or write a paper summarizing their investigation.

High schoolers perform an experiment that measures respiration.  For this performing an experiment that measures respiration lesson, students discuss aerobic and anaerobic respiration.  High schoolers measure the gas produced...

Beginning biologists prepare a sugar solution for yeast cells to live in, and divide it into two different jars. Samples from each jar are viewed with a microscope, and then one jar is placed in a warm environment and the other a cold...

Learners determine if human practices have any noticeable effects on the quality of stream life as measured by the presence of certain macroinvertebrates. They collect, preserve and identify macroinvertibrate samples and quantify the data.

Students are able to use a secchi disk to measure the turbidity of water by determining the depth at which the sechi disk is no longer visible and using the data in a formula to quantify the results. They are able to use Vernier probes...

Students explore velocity and trajectory. Using exterior ballistics rules, students predetermine the path of an artillery shell. Given equations and the firing angle, students determine the velocity and horizontal travel. Students...

Students determine the amount of vitamin C present in 3 samples of juice stored in various light conditions. In this vitamin lesson plan, students investigate the amount of vitamin C present in juice exposed to different quantities of...

Young scholars examine agarose gels to compare a known DNA sample to an unknown sample to determine the quantity and size of an unknown DNA sample.

Students explore number sense by completing a statistical analysis game in class. In this data graphing lesson, students utilize visual references such as colored cubes and tiles to map out the results of an experiment outcome such as a...

Students are able to transcribe to scale the plant features of a common landscape. They determine true north and south and collect and record data on a table. Students calculate a rating for and describe a definition of insulation and...

Young scholars conduct an experiment to investigate the rate of microbial growth at different temperatures. Students predict what will happen to the food at various temperature and test their hypotheses. Young scholars describe the...

Students conduct a lab to determine the best way to separate a variety of mixtures choosing between paper, thin layer and column chromatography. They use chromatography techniques to identify unknown substances and submit a lab report on...

Eleventh graders use titration methods to study properties of antacids. They look at the strength, effectiveness, PH, and effect of supplements taken at the same time. They make observations after the different mixtures are combined and...

Students conduct an experiment to determine the frequency of pulling various parts of an ancient Greek sculpture out of a hat.

Students produce a vertical profile of a stream and map and define thalweg, point bar, and cut bank. They measure flow velocity differences across a stream transect and equate flow velocity with size of substrate sediment collected.
