Buffer Activity Lab Document
Read the Fine Print
Rating
0.0 stars

Part of NCSSM CORE collection: This is the document for a buffer activity lab. Students will measure and record the pH of various solutions and then measure the pH of the solution after the addition of a buffer solution. They will use their results to gauge the effectiveness of the buffers. NOTE: This lab uses CBL probes and TI-83+ calculators.

A Clean Green Sweep: An Aquatic Bioremediation Project
Read the Fine Print
Rating
0.0 stars

Students are introduced to the topic of bioremediation and collect information about Azolla, such as the morphology of water plants as opposed to land plants, the importance of symbiosis, the nitrogen cycle, the use of Azolla in agriculture, and Azolla’s ability to absorb heavy metals. Students formulate the research questions and hypotheses that they would like to investigate. Possible topics include measuring the gain in biomass depending on growth conditions (e.g. CO2 level, iron level in the water, amount of light), or the effect of Azolla on water quality.

Cracking the Genetic Code: Replicating a Scientific Discovery
Read the Fine Print
Rating
0.0 stars

Students are asked to crack a code of different sequences of letters using the messages that those sequences encode. In each of the first three steps, each team is given a different set of letter sequences and corresponding messages. At each step, they will need to re-evaluate their conclusions from the previous steps, and modify their solution to the code. All groups will be working to crack the same code, using different examples. Students should focus on finding patterns and relationships. The crux of the activity is the existence of the code rather than the details of transcription and translation, which can be addressed in subsequent lessons.

Field Research: Discovering the Structure of Soil
Read the Fine Print
Rating
0.0 stars

In this two-part lesson, students learn about soil structure and its organic matter content. In the first activity, students carry out a simple experiment to collect soil samples and test their stability to learn which types of soil are liekly to be more prone to erosion. In the second activity, students find out about the mineral composition of soil samples.
