Students engage in a lab that focuses on animal behavior in an open ended inquiry based laboratory experience. They build an ethogram, display a transition matrix and analyze a Markov Chain. They remove wings from the drosophila and...

Young scientists use a worksheet to help them perform a lab on the decay of a radioactive element. The worksheet serves as both a task guide and a lab sheet for pairs of learners. This activity requires a calculator and has excellent...

Many people think they can't observe plate tectonics, but thanks to GPS, we know that Australia moves at a rate of 2.7 inches per year, North America at 1 inches per year, and the Pacific plate at more than 3 inches per year! Scholars...

In this Olympic bar graph worksheet, students pick a sport from the 2004 Olympic games and find data from the Olympic web page. They graph the scores (times, distance, or speed) and the medals. They answer questions about the variables...

In this acceleration worksheet, students experiment with varying amounts of mass to observe the effects on the force needed to move an object. Students apply Newton's Second Law of Motion to describe the relationship between mass and...

Students examine hurricanes. In this web-based meteorology lesson, students study the relationship between ocean temperature and hurricane intensity. They differentiate between intensity and frequency of hurricanes.

High schoolers solve the following problem concerning the evolution of seed color in pinto bean plants: "How does natural selection change the frequency of genes or traits over many generations?" They use the constructivist approach to...

In this transpiration learning exercise, students will conduct an experiment to measure the rate of transpiration from a plant by measuring how much weight the plant loses over 5 days. Students will record their data and create a graph...

In this solubility learning exercise, students conduct an experiment to see how temperature effects the solubility of salt in water. Students record their data in a chart and then graph the results. Then students complete 2 short answer...

Students, after watching the CYBERCHASE episode, "A Day at the Spa,"represent and count combinations of choices using tree diagrams.

In this plant reproduction worksheet, students follow the steps to complete a science investigation and then respond to 2 short answer questions and complete a data table regarding the investigation.

High schoolers survey and dissect as many fish as possible. They count nematodes, cestodes and crustaceans on the fish, fill out autopsy reports, and transfer data to a chalkboard data table. Students graph the results of the entire...

Students explore various animal brains. In this animal anatomy lesson, students compare and contrast animal brains with the brain of a human. They record several characteristics in a data table for each brain they observe.

Students examine a color-coded map of U.S. acid rain precipitation intensity. Using EPA data table and the blank U.S. map, they record state-by-state values for magnitude of emissions and compare areas of emissions to areas with the most...

Students demonstrate the meaning of dilution and concentration and how pollution can affect the water that you drink. They perform an experiment to calculate the final concentration and dilution factor of solutions. They record the color...

Students investigate how mass affects the speed of an object. In this physics lesson, students record data on the data table and graph results. They analyze findings and formulate a conclusion.

In this stars worksheet, students classify stars by comparing their surface temperatures and absolute magnitude. Students fill in 24 blanks in a data table.

You will need a photovoltaic system and monitor at your school in order to obtain all of the data required to thoroughly implement this lesson. Your class monitors daily temperature and insolation amounts over a two week span of time....

Facilitate learning by using small objects to teach the principles of atomic mass in your science class. Pupils determine the average mass of varying beans as they perform a series of competitive experiments. They gather data and...

How to oceanographers measure the sea's depth? Your scientists will step into their shoes in this application instructional activity, first reading about how the speed of sound and a simple formula give scientists a depth estimation....

In spring, the Bering Sea turns green due to phytoplankton, which live at the surface, experiencing a population explosion. Groups of scholars play a food chain game, writing down food chains as the game is played. After five to six...

Here is a resource with a descriptive approach to explaining the scientific method. It's simple, but effective for both introduction and reinforcement of this concept. 

It's all relevant, really. Individuals use the scientific method to learn more about elements, atoms, and their placement on the periodic table. They conduct experiments using materials common in nature to explore how elements affect our...

Explain the importance of radioactive half-life as your high school biologists demonstrate the concept by performing a series of steps designed to simulate radioactive decay. Pupils use pennies to perform an experiment and gather data....
