This classroom lab is a guided practice for inquiry using brine shrimp as the subject to be investigated.
SSAC Physical Volcanology module. Students build a spreadsheet and apply the ideal gas law to model the velocity of a bubble rising in a viscous magma.
This activity is a lab project where students observe what happens when you try to mix oil and water. It can also be used to work with density.
This activity is a field investigation where students gather data on physical characteristics of the ecosystem surrounding their school.
This activity is a field investigation where students gather data on physical changes of the ecosystem surrounding their school habitat.
In this Spreadsheets Across the Curriculum module, students build spreadsheets and draw graphs to explore a chemical buffer's ability to resist pH change, i.e., the buffer capacity. Quantification of buffer capacity is conceptually straightforward but involves multiple repetitive calculations. The key relationship is the Henderson-Hasselbalch equation: , which follows from the Law of Mass Action and The spreadsheets automate many of the calculations, thereby simplifying the process. Instead of focusing on the calculations, students can see what buffer capacity means and focus on the a deeper understanding of its implications. After reviewing several buffer calculations, the stduents use the spreadsheet to investigate buffer capacity graphically and characterize blood's physiological buffer system. While solving the question of how many breaths one can take before alkalosis sets in, the students manipulate a logarithmic equation, do "what if" modeling, and analyze rates of change from plots of their cacluated results.
This activity is a biology lab investigation where students create habitats to observe decomposers in a controlled setting.
This activity is a hands-on building of atoms of elements 1-20.
This classroom activity where students physically show where the forces are in an arch.
This is a hands-on activity to assess the students understanding of peptide and disulfide bonds formed during protein synthesis. Students demonstrate the process of dehydration synthesis by combining amino acids through peptide bonds creating molecules of water, and one protein amino acid strand. It can also be used to assess students understanding of the process of translation.
Undergraduate student project for building datasets and analyzing the electoral, party system, and mass behavioral characteristics for a set of countries.
Students construct electromagnets and determine that the more winds of wire coil around the core will increase the strength of the electromagnet.
This activity is a guided discovery where students gather information on how to add a seat belt to a clay figure that is sitting on top of a toy car. The clay figure should stay in place when it hits a speed bump placed after a ramp.
This activity is a lab where students gather data on buoyant force and height of and object being submerged in two different types of fluids. The slope of the buoyant force and height is proportional to the density of the fluid. Students compare the densities of the fluids calculated with the actual densities.
A lab where students determine the molarity of sugar and citric acid in samples of lemonade.
Students will discover the terminal velocity to mass relationship and use this information to calculate the air resistance constant. They will evaluate the accuracy of their lab using the Monte Carlo method.
This activity is a project-based inquiry where students design and create a machine to complete a task. Then students will be asked to calculate velocities, kinetic energy and potential energies of various parts of their machine.
Students will observe the patterns of apparent motion of the sun using simple tools.
This activity enables students to calculate the speed of sound in a laboratory setting.
This online game activity allows the learners to calculate their carbon footprint using a French language calculator developed by a Swiss environmental organization. Students will describe their results in French and engage in related expansion activities for the language class.
