In this experiment‚ we used acquired observational data to develop an activity series describing the relative reactivity of the metals being tested. The elements within a periodic table often show different trends in physical and chemical properties depending on the period or group they are apart of. In a periodic table‚ elements are arranged by increasing atomic number in horizontal rows called periods. The atomic numbers represent the number of protons in each element. The periodic table is also

Will no gum or having gum improve test scores? Data Analysis The question being answered in this experiment is‚ “Which gum will improve memorization the best?” The hypothesis for this experiment is‚ “If the gum flavor is altered‚ then one flavor will improve memorization more than another flavor.” The independent variable is the flavor of the gum. The dependent variable is the scores after taking the test with the different flavors. The control group was the test scores without any gum.Experimental

Each element emits a unique color light. The purpose of this experiment was to observe these unique colors and calculate their energy. In order to observe this‚ we placed the physical elements in a 24 well plate‚ dipped wet q-tips into the wells to gather the element‚ and put it over the bunsen burner to observe the flame emitted. While observing the different flames‚ we saw that different elements did indeed emit unique flame colors. Colors such as red‚ violet‚ and turquoise were emitted. All of

Introduction In my experiment I will be testing the differences of wood being soaked in rain and saltwater for a period of days. Then set out to dry to see if it had any change in width and weight. Question Does water affect the weight and appearance of wood over periods of time? Hypothesis I believe Red Oak will have the most change in weight in saltwater and the most change in appearance will be Pine in saltwater. Materials 1/3 8ft of Red oak 1/3 8ft of Yellow Pine 1/3 8ft of Treated
