When the National Research Council produced the National Science Standards in 1995, they did so without including sets of lesson plans nor did they design them as part of a standard curriculum package. They were written to be used as goals for our students’ achievement in science.

Let’s face it, kids of every age love gooey substances! The school year is never complete until you and your students make slime. Depending upon your grade level, the topic you’re teaching, your classroom budget, and the time you have available, there are a number of options open to you.
One of my favorite “recipes” is the ever popular Elmer’s Glue Gak. Aside from the fact that it’s easy to make, it’s rare that you wouldn’t have most of the essential ingredients at your fingertips.
To make Gak:

Whether teaching general science, chemistry or physics, one of the first experiments I assigned was to determine the density of a metal using a set of different sized cylinders of aluminum in a tray.
Each Student:
- Determined both the mass and volume of a single assigned sample.
- Recorded their data point on a large classroom Mass vs. Volume Graph.
- Participated in a class discussion on: determining volume by different methods; drawing a straight line through the data points (including the origin); and calculating the slope of the line (rise over run)
Ron’s suggestions:

When many people think of UV lights or black lights, they think of posters in college dorm rooms, or spooky Halloween displays. Ultraviolet light, however, is an important subject of scientific study. Occupying the segment of the electromagnetic wavelength spectrum between 10 nm and 400 nm, Ultraviolet light is invisible to the human eye. UV lights are often referred to as “black” lights because of this.

Although Robert Fulton is usually remembered as the inventor of the steamboat, it was actually John Fitch who built the first successful steamboat in 1787. Unfortunately, John Fitch ran into financial difficulties which opened the door for Robert Fulton to design and test the Clermont, which was the first commercially successful steamboat, in 1807. Since that time, there have been many improvements on the initial design, but the science behind the steamboat engine is fascinating.
Educational Innovations carries Putt Putt Steam Boats that are wonderful reproduction toys,
which can be used to teach many scientific principles. The science behind how they work is rather complex and often disputed. Read the rest of this entry »
