Easily modified for different abilities, with my low ability I made all the percentages either 75%, 50% or 25% to make it much easier for them. The worksheets can be used in a number of ways, I used them in two ways, I laminated them both in the same pouch front to back for them to use as a mini whiteboard and write directly on them with a whiteboard pen then rub out the ink for reuse for different questions and classes and to use as group work.Or, just print the graph for all pupils to use independently....

By the end of the 8th grade, students should know that all matter is made up of atoms, which are far too small to see directly through a microscope.For the laboratory portion of this lesson, you will have to set up the ring stands, rings, funnels, and graduated cylinders.Fill the funnels with ice before the students arrive in the classroom.For students, understanding the general architecture of the atom and the roles played by the main constituents of the atom in determining the properties of materials now becomes relevant.Having learned earlier that all the atoms of an element are identical and are different from those of all other elements, students now come up against the idea that, on the contrary, atoms of the same element can differ in important ways. 79.) In this lesson, students will be asked to consider the case of when Frosty the Snowman met his demise (began to melt).There were no eyewitnesses, but there are several suspects. You need to determine the exact time at which Frosty was put into the funnels to melt away, leaving no trace.

On a separate sheet of paper, immediately record the volume of Frosty's melted remains (water) in your graduated cylinder and note the time on the clock.

I tell the students that they will now become archaeologists as they play with the Ph ET simulation "Radioactive Dating Game".

I ask the students to divide themselves into partners, and request that one partner to get a computer, while the second partner gets the record sheet they will use.

However, the carbon-14 that was in the organism at death continues to disintegrate.

By measuring how much carbon is left in a sample as well as its radioactivity, we can calculate when the organism died. In this activity, you will work backwards to solve a puzzle, much like scientists work backwards to find the time that an organism died." Procedure Give each student a copy of The Case of the Melting Ice student sheet.

"Carbon-14 undergoes beta decay with a half-life of 5720 years.
