Scaffolding

• TI-83/CBL - Students will be given several sets of sample sinusoidal data and asked to mathematically model the data using sinusoidal regression analysis.  They need to determine if the data is periodic, and if so, calculate the period.  Screens should also be saved to a Word document using the TI-Graph Link software.
• Drake's Equation - Students will view a video and find resources on the Net to learn about Drake's Equation and how it is used to estimate the probability of finding extra terrestrial life

What is the probability of an extra terrestrial life form actually communicating with us? 

Do your students even know the right questions to ask to try to define this mathematically?

• Sound Waves - Students will use the TI-83 and CBL hooked to a microphone to discover 1) the relationships between pitch and wavelengths and 2) the amplitude of a wave and its loudness.
• Net Meeting - Students will form teams and hold simple NetMeeting conferences, using chat, whiteboards, file transfers, and sharing programs
