L1: Does radiation affect me?
I CAN acknowledge that radiation is all around me, understand where it comes from, and that not all radiation is considered bad or harmful.
L2: What is a ½ life?
I CAN recognize that the ½ life of a substance varies from a few milliseconds to millions of years.
I CAN describe that the half life of a substance is the time in which ½ of the material radioactivity decays.
I CAN graph the amount of a substance vs time and know that the shape of the graph is very predictable for radioactive substances.
L3: What are the types of radiation?
I CAN explain that radioactivity is due to a change in the nucleus for alpha and beta decay and energy for a gamma decay.
I CAN write nuclear decay reactions involving alpha, beta and gamma that show the number of protons and neutrons do not change in a nuclear reaction.
L4: Can radiation be used for current and future energy needs?
I CAN describe the difference between fission and fusion including and how each can be used for energy.
