Glue one of the two pieces of graph paper to the cardboard. from the paper’s left edge, and label it “% radioactive material” (see sample graph). Draw a horizontal scale and label it “Half-lives.” 4.

Now draw two identical graphs, following directions below, on the two pieces of graph paper. Glue one red licorice stick to the vertical axis of the cardboard-backed graph. Label from 0 (zero) to 7, with 0 being the point at which the vertical axis intersects the horizontal.

It is a great introduction to the scientific process of deducing, forming scientific theories, and communicating with peers.

It is also useful in the mathematics classroom by the process of graphing the data.

Students use licorice to demonstrate the idea of radioactive decay.

This experiment is best used by students working in pairs.

Yet, a man’s attractiveness to women is mostly based on the personality traits and behaviors that he displays to her during an interaction, rather than on his looks.By extension, this experiment is a useful analogy to radioactive decay and carbon dating.Students use M&M’s (or pennies and puzzle pieces) to demonstrate the idea of radioactive decay.Many nuclear species are unstable and make transitions to other species by absorbing or emitting particles and photons of high energy, gamma rays.The number of nuclei ΔN that decay in a time interval Δt is directly proportional to the number N of nuclei present at that instant and is given by $$ \frac = -\lambda N $$ (1) where λ is the decay constant.

Sure enough, within three days, he told her he was in trouble. The bank needed two more weeks to get all the financing together but he was going to lose the deal if he didn't come up with the money by the end of the week.
