In the Shells lab‚ we were to test the effect of pH on shell strength. The independent variable in this experiment is the type of liquid that we put the shell in and the independent variable is the shells’ strength. The first thing we did was get our materials and label the two shells. The shell that was going into the vinegar was labeled “E” (which stands for experimental) and the shell that was going to be put in the salt water was labeled “C” (which stands for control since it is the control of

Heterotrophs are any organism that consumes organic carbon and energy that is fixed by primary producers. This unit discussed an extremely important pyramid‚ somewhat like a food chain that categorizes heterotrophs. 1st level of the pyramid are herbivores‚ 2nd level are carnivores. Eukaryotes are single celled or multi-celled‚ recapped in this unit‚ the primary consumers are the herbivores‚ the secondary consumers are the herbivore consumers‚ and the tertiary consumers are the top predators.

9/17/2013‚ Lois Andersen & Claire Ma “The Power of Osmosis” The purpose of the lab was to discover‚ through osmosis‚ the concentration of sugar water in a potato. First‚ potatoes were cut into strips about 3 centimetres in length and six strips were individually massed. Next‚ the six strips were placed in 6 different Dixie cups‚ labelled A‚ B‚ Q‚ X‚ Y‚ and Z. Each of the Dixie cups were then filled just enough to cover the potato strips‚ with substances that matched the letters of the cups

When Different Colors of Food Coloring Are Soaked into a Naked Egg‚ Will the Mass Change Depending on the Color of the Ink after 7 Days? The Purpose The purpose of initiating this lab was to test how different chemicals in the outer fluid affects the osmotic properties of a naked egg. Background Information In order to complete this experiment‚ one of the most important things you need to know how to do is how to take the outer “shell” layer off of the egg. The egg shells contain an element known

Marble-lous Momentum Question: What happens to momentum when one marble collides with other marbles? Hypothesis: If a marble collides with increasingly more marbles‚ then the momentum will be transferred more slowly to the final marble‚ because momentum is conserved through an inelastic collision‚ but a longer distance will have be traveled by the kinetic energy. Independent Variable: The number of marbles. Dependent Variable: The momentum of the first marble and final marble. Control Variables:

My results to my findings to my brine shrimp experiment was started on 12-28-15‚ using 4 jars. Each jar contained water‚ salt‚ and brine shrimp eggs. I started by filling each jar with tap water and then adding salt. I added 1 TSP of salt and each jar added ½ TSP more of salt. In my experiment I noticed on the first day‚ 12-28-15‚ in all the jars the brine shrimp eggs were added to the 4 jars. Some observations I noticed were the eggs didn’t sink right away‚ they stayed on the surface for awhile

Lab Experiment (Water) Question Does Different volume of water affect the dissolving speed of 5 mg of sugar? Aim My aim for this lab report will be to find out how the volume of water can affect the dissolving speed of sugar by doing an experiment and test different volumes of water and test it with the same variables. Hypothesis I think the more amount of water will cause the solute to dissolve faster. This is because as there is more water‚ then there will be more solute to be

The main purpose of this lab is to experiment the molecular polarity on the solubility of solutes in variates of solvents and helped us to determine the polarity of the unknown solute. In this lab‚ we observed the effects of adding polar liquid solutes to non-polar liquid solvents. Materials used: Safety goggles 3 graduated cylinders ethanol‚C2H5OH solid iodine‚ I2 glycerol‚ C3H5(OH)3 water 10 rubber stoppers 10 test tubes kerosene ammonium chloride

In this folio task‚ the impact of drug absorption and blood stream concentration‚ on the human body‚ will be observed. The rate of absorption and clearance of the drug‚ relies on many factors. The drugs blood stream concentration‚ time of administration‚ absorption rate‚ clearance rate and the effect of certain parameters‚ will be calculated. This can be completed through using a surge function‚ calculus (derivatives) and straight line graphs (). Graphing technology on the graphics calculator
