Our Goal
Our Goal
For this individual project each student was assigned an element from the periodic table, had to research the element, and create a superhero or a villain based off of its characteristics. The project consisted of creating a two page story and a mini poster, both containing the researched information. In class we each presented our element, allowing us to learn about each of the elements in a different and interactive way.
Periodic Trends Lab
Periodic Trends Lab
This lab was conducted as a way for us to gain background knowledge on the periodic table and its trends. We did two experiments to learn about reactivity and solubility among metals. We came to the conclusion that metal reactivity increases when going down a group but decreases when going across a period from left to right. Another conclusion was that metal solubility increases as you move down a group. We were able to back up these claims by observing reactions between two different metals or metal compounds.
Lab part A
Lab part A
In part A we tested the reaction between calcium, magnesium, and aluminum (all in solid form) and water and hydrochloric acid. We used litmus paper to observe the reaction between water and the metals. Pictured from left to right: aluminum, magnesium, calcium. From top to bottom in each row: water, hydrochloric acid.
Lab part B
Lab part B
In part B we tested the reactivity of alkaine earth metals in their liquid form by combining them with different compounds. The metals tested were (from left to right) magnesium chloride, calcium chloride, strontium chloride, barium chloride, and an unknown metal. The three solutions that were used to test the reactivity were (from top to bottom) sodium carbonate, sodium sulfate, and potassium iodide.
