Composting Competition

0.0 stars

In a multi-week experiment, students monitor the core temperatures of two compost piles, one control and one tended, to see how air and water affect microbial activity. They daily aerate and wet the "treated" pile and collect 4-6 weeks' worth of daily temperature readings. Once the experiment is concluded, students plot and analyze their data to compare the behavior of the two piles. They find that the treated pile becomes hotter, an indication that more microbes are active and releasing heat. Through this activity, students see that microbes play a role in composting and how composting can be used as a carbon management process.

How Fast Can a Carrot Rot?
Read the Fine Print
Educational Use
Rating
0.0 stars

Students 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 have decomposed completely.

Microhabitats: The Habitat of the Rotting Log
Read the Fine Print
Rating
0.0 stars

Students will explore the life that is supported by the microhabitat provided by a fallen tree as they consider the question: Why does a rotting log make a desirable home for certain plants and animals? Students will examine rotting logs first-hand and will record data about the condition of the wood as well as the animals and plants found on/in/under the log.

Student Chemical Reactions Demonstrations
Read the Fine Print
Rating
0.0 stars

In this lab activity, students are given a set of instructions for producing chemical reactions. Students work in pairs or small groups to investigate the reaction they are given. They determine what has occurred, what is produced, what type of reaction that has occurred, and write a chemical equation for it. The students will then demonstrate their reaction to the class with the explanation.

T4T Using Decomposition to Subtract
Conditional Remix & Share Permitted
CC BY-NC-SA
Rating
0.0 stars

This resource is part of Tools4NCTeachers.

The purpose of this lesson is to provide an opportunity for students to solve a subtraction problem that requires regrouping. It explores the idea of decomposing numbers through regrouping. Ideally, this lesson should span over 2-3 days to allow students time to fully explore this critical concept.
