Science for Seniors September Experiment

Monday, August 30th, 2010

This month the children return to school, and so does Science for Seniors. The children will need glue for art projects in this experiment the residents can make a glue for a craft project.

Materials: One cup of flour, 1/2 cup of water, newspaper, paint and brushes.

Process: Mix them together and they make a glue that can be brushed onto newspaper. Glue together several layers of newspaper and after it dries it can be painted and used in an art project.

Science behind the Experiment: The chemical reaction between water and flour makes a paste that will dry and become a hard surface ready for re-use in an art project. Every American uses a 100 foot tree worth of new paper materials each year. Recycling saves money, energy used in the paper making process and saves trees that return oxygen to the air.

Science for Seniors – August Experiment

Tuesday, August 3rd, 2010

This month’s experiment focus is on water and why things float.

Objects float when they are less dense than the water they displace.  To demonstrate this science fact you will need two clear plastic cups, two eggs – on fresh and one hard boiled, and salt.

Ask the residents – which egg do you think will float?

Place the fresh egg in fresh water. It will sink. Place the hardboiled egg in fresh water. It will sink. Now add salt to water and once again test both eggs. Both will float because salt water has more density than fresh water.

Coming in January – monthly experiments in Creative Forecasting Magazine.
