A cool science fair project that is centered on biology gets students to cultivate their own slime molds. Provide your students with a non nutrient petri dish, Physarum (which will come on filter paper), a beaker of oatmeal flakes, a log book and a camera. Students add the Physarum on filter paper and two oatmeal flakes to the non nutrient petri dish and place in a darkened area at room temperature for no less than 12 hours the photography development black room at your school is ideal. Students check back after at the start and end of each school day, noting their observations and adding two more oatmeal flakes. A slime mold begins to develop over the course of a couple of days. Students present their findings at the science fair with photographs and log book entries.
Often there are issues with health and safety when students carry out cool chemistry projects for the science fair. One example of a project that avoids safety issues allows students and visitors to their science fair stall to write with invisible ink. Take a Q tip, a fountain pen that has not used any regular ink or a paintbrush and dip it into a bowl of lemon juice. Using the chosen implement, students write out a message on a piece of plain white paper and allow it to dry, so it appears there is no writing on the paper. Get a heat lamp and warm the dry paper up so that the message written in lemon juice shows brown.
An example of a physics experiment involves re creating a mini tornado using a pair of empty plastic soda bottles. Assist students in setting the scene for their miniature tornado by drilling a 1/2 inch hole through the centers of two plastic bottle caps and caulking the holes with silicon. Provide students with the bottle caps and have them tape the two together so the holes are aligned. Fill one bottle with water and screw the other bottle onto it using the taped caps. The two bottles should be combined with the liquid in the bottle on the bottom. Turn the contraption upside down and whirl it around in your hand so liquid breaks the silicon seal and creates a mini tornado in the lower bottle.
One cool project that brings science to life Air Jordan 20s assesses the effects of an earthquake on a gelatin city. Use an Internet satellite image resource, such as Googlemaps or Flashearth, and get an aerial view of your local community or school grounds to use this as your blueprint. Students build a replica of their community or school grounds on a table with rollers using gelatin. Form the gelatin city by using molds of building shapes and waiting until the gelatin has set. If you are running short on time, scale back your ambition and settle for only a couple buildings. The gelatin structures do not have to look identical to buildings, as the effect will be the same. It is Jordan Retro 8 best that you prepare this project on a table in the area where the fair will be held. Get students to violently shake the table on project day to demonstrate the impact of an earthquake on the gelatin community.
