Credit can be confusing for teens, some of whom are already using credit cards. Clear up misconceptions with this group research activity which has a solid outline with a lot of room to adjust to your needs and resources. Groups are...

Students explore concepts of probability and independent events. They develop a formula for deviation percentage.

Young scientists gain a better understanding of space, the solar system and its vastness by creating a scale model. Students first need to calculate the distance between each of the nine planets according to the size of their scale. This...

What do magnetic fields look like? The best way to learn about magnetic fields is to try identifying them for yourself. Scholars will understand the importance of magnetic fields after completing this experiment. The extension activities...

Students practice the basic principles of probability by conducting an experiment, determining if a game is fair, collecting data, interpreting data, displaying data, conducting analysis, and stating and applying the rule for probability.

Fourth graders represent a new predator on a population of colored worms. They mathematically determine the effect of the new predator on the survival and reproductive rates of the worms, simulating natural selection at work.

Students use data from simulations to make theoretical generalizations. They discuss possible relationships between several given events and gain understanding about their own mathematical intuition about likelihood.
