Experiments You CAN Try at Home!
The RIT College of Science Student Advisory Board plans to present "DIY Science: Experiments You CAN Try at Home!" This exhibit will include 5-6 separate experiments (listed as follows) - visitors will be provided with a document containing the instructions and science behind each experiment
Non-Newtonian Fluids (Gak/ Ooblek): This experiment will have two portions. One portion will consist of a plate of cornstarch and water mixed together (known as gak or ooblek). This portion gives individuals the opportunity to see how a Newtonian fluid is like a solid and a liquid. The second portion involves sound. A speaker can be used to visually portray sound waves. Cleaning Up/Preventing a Mess - Tarp on ground to prevent gak spills; Soap and water recommended to clean up gak before it dries
Cabbage Litmus Paper - As a demonstration of a common tool used in chemistry to demonstrate base and acidity of various substances, homemade litmus paper will be made using red cabbage juice and coffee filters. This will then be tested at the exhibit with acidic juices (such as vinegar) and bases (such as baking soda - aka sodium bicarbonate).
Transpiration in Plants - This experiment will portray water uptake in plants through the use of colored water and white carnations.
Hydrophobic sand - This experiment will demonstrate how hydrophobic substances and water do not mix. Scotchgard will be used to spray sand to give it a "water proof" property. The hydrophobic sand will then be added to a clear container of water where it can be seen not absorbing water as sand typically does
Ferrofluid - Ferrofluid is a solution with magnetic particles. Exposing this liquid to a magnet demonstrates how magnetic objects interact with one another. This demonstration is recommended to be in a sealed container.
The goal of the exhibit is to increase interest in the natural sciences through portrayal of exciting scientific experiments that viewers can safely try at home. This year, the demonstrations typically shown in-person will take the form of detailed materials/instructions/science that families can try out at home.
This proposal is subject to change based on the availability of COSSAB members to prepare documentation of the experiments based on our resources.
