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.
In my classroom I always used the National Standards when designing my lessons, and they were always clearly represented in the objectives I set for my students. I have found that the topics of Force and Motion, as well as Air, (as part of a weather unit), can be easily taught using balloons to demonstrate the concepts of each. Read the rest of this entry »

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.
- 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)
1. The Density Sphere Experiment Kit (DEN-10) or Steel Sphere Density Kit (DEN-350) are ideal beginning sets. The Density Paradox (DEN-300) is interesting as the solid object sinks and then floats in one beaker of water, but when put into a second beaker of water, it floats at first and then sinks. The Poly Density Kit (DEN-460) is interesting because Read the rest of this entry »
