This interactive addresses the question if we can reduce CO2 emissions by 20% of 1990 levels and help avoid dangerous climate change? Users of this interactive can manipulate changes to various sources and uses (supply and demand) of energy with the goal of reducing C02 emissions in Great Britain by 80% in the year 2050.

2 x 2 Contingency Tables
Read the Fine Print
Rating
0.0 stars

Created by David Lane of Rice University, this applet simulates experiments using 2 x 2 contingency tables. You specify the population proportions and the sample size and examine the effects on the probability of rejecting the null hypothesis. The author provides instructions and then five different exercises to practice these concepts. Overall, this is a nice interactive resource that allows users a more hands-on approach to statistics.

In this outdoor game, learners play the roles of gray or red squirrels gathering and storing a supply of food in "fall" and recovering enough of them to survive the "winter." Learners carry bags representing their cheek pouches for carrying food. Learners investigate the advantages and disadvantages of how these two kinds of squirrels store food differently.

Alternating to Direct: Rectifying Alternating Current
Read the Fine Print
Rating
0.0 stars

The Materials Science and Technology Teacher's Workshop (MAST) provides this activity for classes learning about diodes and electrical currents. The laboratory illustrates how diodes can be used to rectify alternating current. It uses a galvanometer to determine the direction of current flow when an AC or DC current is applied to the circuit containing a diode in series with a resistor and a galvanometer.The lesson includes step by step directions for the experiment.The activity should require about 20-30 minutes of class time to complete. Discussion questions and teacher notes are included.
