Acid Rain Lab Report Introduction: The problem was to see how crushed chalk and whole chalk weather differently. The independent variables are The temperature of the liquids The surface area of the chalk‚ crushed vs whole The dependant variable was the weathering of the chalk; this was calculated by measuring the foam reactant. Procedure: Part B- For the two partners recording data with the room temperature liquids‚ the materials where collected first. Two of the graduated

My drug is LSD (Lysergic Acid Diethylamide) 2. Usually LSD is taken by mouth. It is dissolved into a liquid and soaked into blotter paper‚ which is then cut into quarter inch sized doses. These are also called tabs‚ trips‚ or hits. Although it is less common‚ LSD powder can also be squeezed into tiny pills‚ called microdots‚ or placed into capsules. The liquid itself can be squeezed into the eye. 3. LSD is manmade. 4. Battery Acid‚ California Sunshine‚ Dots‚ Golden Dragon‚ Pane‚ Looney Toons
