Dirty Decomposers
Students design and conduct experiments to determine what environmental factors favor decomposition by soil microbes. They use chunks of carrots for the materials to be decomposed, and their experiments are carried out in plastic bags filled with dirt. Every few days students remove the carrots from the dirt and weigh them. Depending on the experimental conditions, after a few weeks most of the carrots will have decomposed completely.

Sliding and Stuttering
Students use a spring scale to drag an object such as a ceramic coffee cup along a table top or the floor. The spring scale allows them to measure the frictional force that exists between the moving cup and the surface it slides on. By modifying the bottom surface of the cup, students can find out what kinds of surfaces generate more or less friction.

Heredity Mix ’n Match
Students randomly select jelly beans (or other candy) that represent genes for several human traits such as tongue-rolling ability and eye color. Then, working in pairs (preferably of mixed gender), students randomly choose new pairs of jelly beans from those corresponding to their own genotypes. The new pairs are placed on toothpicks to represent the chromosomes of the couple’s offspring. Finally, students compare genotypes and phenotypes of parents and offspring for all the “couples” in

Rocks, Rocks, Rocks
Student teams will test rocks to identify and record rock properties such as luster, hardness, color, etc., and classify rocks as igneous, metamorphic and sedimentary. They will complete a worksheet table with all of their rock properties, and then answer some worksheet questions to deepen their understanding of rock properties and relate them to the cavern design problem.

Improve the System
This activity will lead your class through identifying possible solutions to the design problems that the current west corridor of FasTracks faces. The students will combine what they have learned from all three previous activities to come up with possible solutions to the design problems faced by the system. This activity requires the use of the FasTracks Living Lab.

What Is Energy? Short Demos
Three short, hands-on, in-class demos expand students’ understand of energy. First, using peanuts and heat, students see how the human body burns food to make energy. Then, students create paper snake mobiles to explore how heat energy can cause motion. Finally, students determine the effect that heat energy from the sun (or a lamp) has on temperature by placing pans of water in different locations.

7.5.2a Adapt your strategy to overcome difficulties

Often plans run into difficulties because of unforeseen problems or changing circumstances. For example you may be running over your deadlines, the resources or support you were expecting are unavailable to you, or your personal circumstances may have changed. Plans are only a means to an end, however. If you run into difficulties, take some time to think about what effect they will have on your plans, and what changes you may need to make to your overall strategy to achieve the outcomes you
