Protein Evolution part of Examples

In this activity students explore the evolution of proteins by comparing 2D and 3D alignments of orthologs and paralogs.

Long Term Ecological Resources part of Examples

Students analyze data on temperature and precipitation collected from 26 different Long Term Ecological Research sites and compare them with annual net primary productivity. The students then form an ecological rule to explain their results.

Monohybrid Fruit Fly Crosses: A Simulation part of Examples

This assignment uses a computer simulation of fruit fly genetics to have students design and interpret monohybrid crosses of a trait with simple dominant and recessive alleles. Detailed instructions with animated examples, background material, a sample report and a rubric are included.

Using Mass Balance to Understand Atmospheric CFCs part of Examples

Students use an interactive online mass balance model help understand the observed levels of chlorofluorocarbon CFC-12 over the recent past.

Quantitative Skills: Probability and Statistics:Describing Data Distribution, Models and Modeling, Graphs

Sun Spot Analysis part of Examples

Introductory students use Excel to graph monthly mean Greenwich sunspot numbers from 1749 to 2004 and perform a spectral analysis of the data using the free software program "Spectra".

Quantitative Skills: Differential Equations and Integrals, Probability and Statistics:Describing Data Distribution, Graphs, Fourier Series, Spectral Analysis

Measuring velocity of objects using video clips part of Examples

Students learn to determine the velocity of moving objects by doing simple analysis of video clips.

Conservation of energy of a rollercoaster using high speed video part of Examples

A high speed video clip of a roller coaster is used as an example of conservation of mechanical energy. Student use the video to determine whether mechanical energy is conserved while the roller coaster rolls up, and then back down a hil.

Ocean Circulation part of Examples

Students view and analyze buoy, satellite, temperature vs. depth data to learn about ocean circulation and how is related to atmospheric circulation.

Reflection and Absorption of Light part of Examples

Students use a microcomputer connected to a light sensor and temperature probe to explore the reflection and absorption of light.

Comparing Sunscreens part of Examples

Students use a microcomputer connected to an ultra-violet sensor to compare the relative blocking power of different SPF sunscreens for the UVB region of the solar spectrum.
