Observing Osmosis in Potato Cells Planning Purpose: To observe the effect of osmosis on plant cells. Hypothesis: The higher the salt content of the water‚ the lower the mass of the potato. Variables: Independent: the salt percentage of the solution Dependent: the weight of the potato in grams Controlled: the amount of water the length of time between measurements the method of measuring the type of plant cells tested Equipment: (as seen on 2A Human Biology task sheet)

Extraction of SSVEP Signals of a Capacitive EEG Helmet for Human Machine Interface Abstract— The use of capacitive electrodes for measuring EEG eliminates the preparation procedure known from classical noninvasive EEG measurements. The insulated interface to the brain signals in combination with steady-state visual evoked potentials (SSVEP) enables a zero prep human machine interface triggered by brain signals. This paper presents a 28channel EEG helmet system based on our capacitive electrodes
