Find out how archeologists reconstruct the ancient history of the Earth using radiocarbon dating to determine the age of artifacts—everything from nutshells to parchment maps! Students “piece together” the process of carbon-14 dating by arranging a... AP7194 - $39.15

Roll the dice! Radioactive decay is a spontaneous and completely random process. The probability that a specific atom will decay after a certain period of time can be modeled by another random process, the rolling of dice. In this cooperative classroom... AP7198 - $27.60

An archeological site in Flinnlandia was recently excavated and ancient artifacts were recovered! Now it's time for your students to become “real-world” scientists, determine the age of the artifacts, and see how long ago this civilization lived. Students... AP4555 - $17.80

Nuclear stability and radioactive decay are important concepts to understanding nuclear chemistry, the size of the nucleus, and the energy that holds it together. In this engaging activity, students will determine the natural decay of uranium-238 to... AP6721 - $71.15

Students model the process of radioactive decay by studying the “decay curves” for a variety of multi-sided dice. Radioactive decay is a spontaneous and completely random process. The probability that a specific atom will decay after a certain period... AP6895 - $49.90

The most comprehensive radioactivity shielding kit available! Using a safe, low-level radioactive source and radiation monitor, students determine the shielding effectiveness of a wide range of materials. Students will quickly recognize the differences... AP8977 - $104.95

Radioactivity and half-life are sometimes difficult for students to understand. With this activity your students will readily grasp the general concepts of radioactivity and half-life determination. Using reusable, simulated plastic radioactive atoms... AP5881 - $10.55

Radioactivity and half-life are sometimes difficult for students to understand. With this activity your students will readily grasp the general concepts of radioactivity and half-life determination. Using reusable, simulated plastic radioactive atoms...... AP6745 - $62.25

Alpha, beta, and gamma radiation are quite different in terms of their composition and properties. Different types of nuclear radiation require different types of shielding to protect workers from its harmful effects. Radiation protection comes from... AP5768 - $1,113.85

Demonstrate what Einstein theorized about back in 1905, and later confirmed-that the energy of an electron ionized by a photon of light depends only on the wavelength of light, and not its intensity. Irradiate the photocathode with a monochromatic... AP6152 - $13.80

Take a “quantum leap” to see if you can determine the precise location of an electron around the nucleus of an atom! This engaging lab helps students visualize the shapes and relative positions of the 1s and 2s orbitals in a hydrogen atom. It also... AP6575 - $31.15

An in-depth poster that looks at the inner workings of the atom. The atom is “dissected” into its neutron, proton, and electron components. These, in turn, are broken down into their building blocks, the quarks, the gluons, and the mesons. Each particle... AP6149 - $13.80

What could it have been like to imagine the nature of an atom? How difficult is it to produce a model of something that can't be seen? The Think Tube allows students to appreciate the challenges associated with things that cannot be directly observed....
