Osmosis Lab Report The essential focus of the experiment was to acquire data for the mass change resulting from osmosis in order to determine the carbohydrate solution of the carrot cells. The carrots were a vegetable used within the experiment with a carbohydrate solution around .5 M. The hypothesis is if there are carrots in different carbohydrate solutions then there will be a percent change in mass. The carrots have large vacuoles that hold water‚ this allows the mass to increase when the hypertonic

Salt from green beans Name: Ashni Couprie and Dennise Susanto Class: 5c Introduction From previous experiments we ’ve learned that salt is extracted from green beans. To be more specific: salt is extracted from when the beans are cooked in water in which salt has been dissolved. This experiment is based upon the osmoses theory. According to this theory the cell walls of the green beans are what we call a semi permeable membrane. This membrane only lets water through and not the substance

Calorimetry Experiment Purpose: The objective of this lab is to determine the enthalpy change for NaOH(aq) + HCl(aq) NaCl (aq) + H2O(l) Procedure: Before measuring the enthalpy of acid base neutralization‚ my partner Brian and I determined a calorimeter constant‚ using a homemade polystyrene calorimeter. With the following formula and data: qhot= cm (Tf-Ti) qcold=cm(Tf-Ti) SYSTEM DATA SURROUNDINGS DATA Water cold Mass: 50mL Water hot Mass: 50mL C=4.18 C=4.18 Ti=20 C Ti=31

Part I - Illumination Experiments (1924-27) These experiments were performed to find out the effect of different levels of illumination (lighting) on productivity of labour. The brightness of the light was increased and decreased to find out the effect on the productivity of the test group. Surprisingly‚ the productivity increased even when the level of illumination was decreased. It was concluded that factors other than light were also important. Part II - Relay Assembly Test Room Study (1927-1929)
