Students explore symmetry.  In this geometry and scientific inquiry activity, students design paper airplanes with middle line symmetry, as well as right, obtuse, and acute angles.  Students measure the plane's angles using a...

From any angle, this interactive is helpful. Earth science super stars explore a location's angle from the equator through a hands-on activity. Questions guide learners as they test their knowledge of direction and geometry used in...

Students read about specific instances of arsenic in history and share these stories with each other. They identify, after reading the articles and sharing, what role arsenic played, how arsenic enters the system and what its effects...

In this epidemiology worksheet, students read a scenario about people reporting an acute episode of gastrointestinal illness. Students determine if its an outbreak and then complete 4 short answer questions.

Students demonstrate how epidemiological investigations of outbreaks are performed. They illustrate the principles of hypothesis formation and testing by epidemiologic study in the setting of an acute foodborne disease outbreak.

Students observe brine shrimp as they are affected by household cleaners, develop observation scale, collect and analyze data, and discuss how household products and pesticides negatively impact environment.

Twelfth graders investigate global responses to fighting the spread of severe acute respiratory syndrome, then write a news report for people in their region of study.(April 3, 2003)

High schoolers investigate the cause of death of a fictitious school janitor. They develop hypotheses based on information discovered by examining the labels of household chemicals.

How are raptors and airplanes alike? Combine science and language arts in this fun and interactive project. Young scientists research the animal in order to design their own aircraft, and compete in a contest for farthest, fastest, and...

Students determine the normal behavior of California blackworms. They determine how various concentrations of assigned toxicants affect the worm's behavior. Students are introduced to testing of potential toxicants, an important...

In this stars rise in the east worksheet, learners use geometry to show how the Earth rotates from west to east and why celestial bodies appear to rise in the east and set in the west. Students draw a figure and label given points in...

Students construct aluminum foil boats that float while holding the greatest number of pennies. They investigate the concept of water displacement, record their results, and watch a Bill Nye video on buoyancy.

Students examine the health effects of hazardous waste on people. They work together to complete an experiment in which worms are exposed to chemicals. They discuss the results of the test.

Students state the some diseases are the result of infection. They describe the risks associated with biological hazards, such as viruses. Pupils name ways that infectious disease can be prevented, controlled, or cured. Students...

Students are required not to change their usual eating pattern while recording everything they eat and drink for 1 day. They evaluate the nutrient composition of their diet, as well as their dietary intake and behavior within the...

Students define several vocabulary terms related to chemicals and toxicology. Students calculate chemical concentrations in water and explain the toxicological principles that govern safety of substances. Students conduct an...

Learners examine the dangers of mountain climbing. After watching a video, they discuss the role of a German research team going into the Alps to predict who is going to adjust to the change in oxygen levels. They discover the...

In this invertebrate worksheet, students review characteristics of the different types of invertebrates. This worksheet places 32 vocabulary words into a crossword puzzle.

In this nuclear chemistry worksheet, students are given the biological effects of nuclear radiation. They are also given a list of uses of nuclear chemistry and Einstein's theory of special relativity to calculate the energy change in...

Students learn the meaning of LD50 through lecture and discussion. Through experiment, students graph and calculate the LD50 of salt on fresh water amphipods. Students compare results of the experiment with pesticides and pollutants.

Students read about a cholera outbreak in the 1840's. They read maps, predict how cholera moved throughout the country and participate in a lab activity that demonstrates how disease is spread. They compare cholera through time.

Students determine where to buy the heaviest earthworms as they study invertebrates. They create a double bar graph of the results of the weight data.

In this chemical reaction worksheet, students label the missing particles as natural decay, induced, fission, or fusion. Students calculate the energy change for the given reactions. This worksheet has 6 fill in the blank and 4 problems...
