Curated OER
Radioactive Beans
Students investigate radioactive atoms. In this radioactive beans lesson, students experiment with split peas and beans to determine what happens when a radioactive atom decays.
Curated OER
Geological History Vocabulary
In this geological history worksheet, students define 17 terms associated with index fossils, nuclear decay, and radioactive decay.
Curated OER
Absolute Ages of Rocks
In this rocks worksheet, students review the process of absolute dating of rocks and compare it to the relative dating process. This worksheet has 16 fill in the blank questions.
Curated OER
Nuclear-Powered Space Probes
For this space probes worksheet, students read about radioisotope thermoelectric generators and how they work. Then students complete 3 short answer questions.
Curated OER
Radiation Lab
In this radiation worksheet, students use a data table to determine what kind of radiation is being emitted by unknown sources. This worksheet has 3 problems to solve.
Curated OER
Radiation vs. Shielding
In this radiation activity, students compare the effects of shielding on radiation on known isotopes. This activity has 2 problems to solve.
Curated OER
The Nucleus
In this atoms worksheet, students review terms associated with atoms which includes isotopes, transmutation, and radioactive decay. This worksheet has 11 short answer questions.
Curated OER
Using Radioactive Decay To Determine Age
Learners explore the process of carbon dating fossils to determine their age. They simulate radioactive decay using pennies in a shoe box. Heads represents a decayed atom each time they shake the box. They use the data to calculate the...
Curated OER
What is the Relationship Between Radioactivity and Radon?
Learners examine the relationship between radioactivity and radon. They practice using a geiger counter with different materials. They answer questions to complete the instructional activity.
Curated OER
What is Radioactivity?
Students use a geiger counter to record changes in the amount of radioactivity produced by different objects. They research articles which mention radiation and discuss them. They work together to complete an activity and worksheet.
Curated OER
Dangers of Radiation Exposure
Students explore sources of high-energy radiation and calculate student exposure to ionizing radiation over the past year.
Curated OER
Radioactive Waste
Students assemble a nuclear waste cube to represent the amount of waste from one person over a period of 20 years that would be left after all stable materials had been recycled. They discuss current methods of containing waste.
