How old is the plant? Here is a task that presents the exponential decay function for carbon 14 in a plant. Pupils use the function to estimate the amount of carbon 14 in the plant when it died and analyze the function to find what...

Scientific models help explain ideas and concepts to non-experts. The online activity covers conceptual, mathematical, and physical models. Through four multiple-choice questions and three discussion questions, scholars gain a deeper...

Take the old baking soda and vinegar volcano to the next level by using it to study repeated lava flows over time, examine geologic features on Earth and Mars, and speculate about some of the formations on Mars. 

Fourth graders measure the change in the size of their shadow over time. They visit a fixed structure and record the date, the time, and the measurement of the length of their shadow. They do this over the course of the school year. They...

In this time zones worksheet, students are given a map of the Earth indicating the time zones, the prime meridian and the international date line. Students answer 5 questions about solar occurrences and determine when each would be seen...

In this radiation and lifestyles worksheet, high schoolers are given 5 problems about a person which indicate her exposure to radiation. Students calculate her total dosage to radiation in each problem based on her exposure.

Plant growth experiments offer rich, cross-curricular learning opportunities that can really excite and engage young learners. For this series, children work in pairs planting, measuring, and comparing the height of bean plants in order...

After planting a bean seed in a jar, young scientists observe the growth patterns over several days. As the bean becomes a sprout, and the sprout becomes a plant, partners measure and plot the data. They notice patterns, practice...

Did you know scientists can tell the age of an asteroid by looking closely at its craters? This final lesson of a six-part series focuses on two asteroids, Gaspra and Ida, in order to demonstrate the concept of dating asteroids. Scholars...

In this geological time activity, student use a geologic time scale to understand the difference between eons, eras, and periods. Then students complete 2 short answer questions.

Students construct a geologic timeline the size of a football field. They work in small groups to calculate the yardage for significant events in the Earth's history and then as a class pace out all of the events.

Use circle time to work on counting. Kindergarteners practice the months of the year, say the full date, chart the day's temperature, count to 100, and sing the alphabet song. This kind of daily routine cultivates deep roots for...

Students plot the migration paths of birds using latitude and longitude data from a table.

In this circuits worksheet, students answer 25 questions about passive integrator circuits and passive differentiator circuits given schematics showing voltage. Students use calculus to solve the problems.

Children enjoy playing with silly putty, but it provides more than just fun. Young scientists make their own silly putty using different recipes. After a bit of fun, they test and graph the viscosity of each.

In this radioactive decay and half-life worksheet, students use given half-lifes to calculate the amount of time it will take for certain amounts of elements to decay. They also find the age of samples and determine how many grams of...

Students generate a radioactive decay table for an imaginary element using a box filled with pinto beans and M&M's. They use their data to plot a decay graph, develop the concept of half-life, and use the graph to "age" several samples.

Students conduct a simulation to determine radioactive decay and half-life. Using pennies, dice or sugar cubes as isotopes placed in shoe boxes simulating rocks, they hold five trials representing 1000 years each to find the theoretical...

In this temperature scales worksheet, students are given the equations to convert from Fahrenheit to Celsius and from Celsius to Fahrenheit. They apply to equations and convert given temperatures.

In this math, science, and physical education activity, students brainstorm and study about the muscles that are used while participating in different Olympic sports. They color the muscle groups of the body by follow the directions...

In this kinetic energy and mass worksheet, students read about coronal mass ejections detected by the SOHO satellite. Students complete a data table that shows the relationship between kinetic energy, speed and mass. They convert the...

Students explore the concept of time. Through discussion and artistic projects, they define time in their own words and tell how it is used to represent the seasons. Students draw a picture to portray time as it elapses during the...

Students explore the evolution of time measurement, and explain the relationship of sunrise/sunset to length of daylight. They collect data and calculations to determine length of daylight during a given day.

Students work with thermometers to complete problems about temperature. They investigate cooling patterns, how location affects temperature, and what happens when water having different temperature is mixed. They measure temperature in...
