In this math worksheet, students discuss the natural frequency ω0 of the system and how it is the number of oscillations of the spring in 2π units of time.

Students participate in a pedometer challenge as part of their ongoing physical education program. They use the pedometers to measure the number of steps they take over a given amount of time. They are encouraged to set improvement goals.

Fourth graders plan a picnic using weather data. Using accumulated weather data from various sources, they create a graph of the weather conditions in their region for a given period of time. Students interpret this data to predict the...

In this writing worksheet, students read about how to write a successful introduction and conclusion. For example, students are encouraged to begin with an incident, real or imagined, which illustrates the point of discussion.

Students study Charles Darwin's evolutionary theory and how he applied it to orchids.  In this evolution lesson students repeat Darwin's orchid pollination experiment.

Learners examine the effects on motor functions in mice. They make observations and graph their data. They analyze the data and draw conclusions in each of the three experiments.

Students explore and explain how mutations in the DNA sequence of a gene may be silent or result in phenotypic change in an organism and in its offspring. They analyze how evolution and biodiversity are the result of genetic changes that...

Students study the basic components of a modern wind machine.  In this investigative lesson students investigate and find out if there are any wind machines in their state, how many and how much power they produce. 

Students summarize the steps of the scientific method. In this life science lesson, students explain the importance of varying only one variable at a time. They analyze possible flaws in their experiment.

Students create a memory game featuring the Arctic and, more particularly, the Arctic hare. They examine a few pictures on a website embedded in this plan in order to get an idea of the Arctic landscape and the activities of the Arctic...

Students use, with increasing confidence, problem-solving approaches to investigate and explain mathematical content. They make and test conjectures. They use tables and graphs as tools to interpret expressions, equations, and inequalities.

Learners consider how topography affects weather and human activity. Students simulate a mountain range and observe surrounding wind patterns.

In this unit, 3rd graders investigate one variable to see if they can make a paper plane fly farther. They use scatter plots to establish a possible relationship between variables then use what they have found to make a paper plane to...

Studens collect and graph data. In this algebra lesson plan, students use a CBL and CBR with a TI Calcualtor to observe linear graphs. They use the correct vocabualry as they discuss the collected data.

In this entropy worksheet, students calculate the change in entropy and rank absolute molar entropies. This worksheet has 12 problems to solve.

Students will identify and solve problems related to inverse variation and the constant of the cf the variation. Students will apply terms related to inverse variation and the constant of the variation.

The student will use a variety of methods inculding tables, equations and graphs to find the constant of variation and missing values when given a relationship that varies directly.

This site gives a definition for direct variation and an example problem.

Students will use this activity for the following Algebra concepts: Review of Direct Variation; Properties of direct variations; Finding the constant of variations from data sets; Find missing values in data sets both numerically and...

Here is a site that clearly and thoroughly explains direct and inverse variation. There are example problems solved, problems for the student to attempt, and answers to the student problems. Point this site out to students who have been...

This is a page on inverse variation taken from a textbook. Contains a definition, examples, and practice problems with answers.

Provides an explanation and examples of variation.
