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 study a way to quantify the process of photosynthesis during a given time using the Elodea plant. They design a hypothesis that they test in the hands on activity. They compare the amounts of photosynthesis that occur during low...

Pupils often wonder how we know the distance to various stars. Starting with a thought experiment and progressing to a physical experiment, they determine the brightness and distance to various stars. The evaluation requires...

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...

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

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.

Students investigate carpooling and determine to what extent it occurs in their community for a carpool challenge. In groups, students create a survey then collect, calculate and record data to determine how much pollution could be...

Students perform an experiment that measures respiration.  In this performing an experiment that measures respiration lesson, students discuss aerobic and anaerobic respiration.  Students measure the gas produced by putting...

Students investigate the finding of a hypothesis and how it can be tested.For the experiment they will be using the concept of probability. Students design an experiment and test the hypothesis. Then the results are graphed showing the...

High schoolers investigate the concepts of probability. They use data to find the central tendency, median, and mode. Students design and play a game in order to practice the concepts. They also complete a table with data that is analyzed.

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 explore multiplying fractions and their relationship to parts of a whole. They draw and shade fractional parts to show parts of a whole and fractional parts of a fraction. Pupils also use an Internet site for interactive...

Use paper strips or models to relate division problems to division of fraction problems. Since the materials can be broken up, it helps them to show how they can complete repeated subtraction with fractions and not just whole numbers.

Students 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.

In this thirteen page worksheet, students solve four sets of exercises concerned with hypothesis testing.  A hypothesis testing summary is provided.

Break up multiplication into more easily conceptualized math operations. Scholars first examine an array of apples and write a multiplication sentence to represent it. Then, they determine which of four sets of addends is equivalent to a...

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...

High schoolers 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...

In this language arts worksheets, students will study word charts of adjectives. Students will focus on various uses of adjectives including qualifiers, observation, size, and description words.

In this asteroid and comet worksheet, students read about the formula used to determine the brightness of asteroid. They apply this formula to solve 2 problems about asteroids and their brightness.

Students explore energy efficient appliances.  In this economics and ecology lesson, students compare and analyze EnergyGuide labels of various appliances.  Students discuss federal government involvement with consumer...
