"Hello, I'm Jeff Danglo aka Jeff Danger, Science Ranger. I've been performing my popular science show in New England for seven years and I sincerely believe students really do leave my show with a greater understanding of science. Using this experience, my 90 minute workshop provides K-6th teachers with the knowledge to create memorable learning experiences in physics and chemistry.
Am
I worth it? Can I improve science teaching? View my teaching
videos right now and decide for yourself!

Workshop focus is hands-on, interactive, fun learning activities
using inexpensive materials.
My objective is to: a) increase teacher knowledge of scientific concepts
and methods b) increase confidence in teaching science
c) RAISE TEST SCORES!

| Properties of spinning objects and gyroscopes, and their role in navigational instruments. | Lasers produce an intense beam of light of one wavelength or color, which can be refracted or 'bent' by a prism. | Motion of objects is affected by friction. |
| An object produces sound when it vibrates in matter - a solid, such as earth; a liquid, such as water; or a gas. We hear sound waves traveling through air. |

Gravity is the natural force that pulls objects toward the earth. Magnetism is another natural force. |
| PV Cells transforms solar energy to electrical energy. | Sound waves have energy and can transfer energy when they interact with matter. | The three basic subatomic particles are protons, neutrons, and electrons. |
| Bernoulli Effect - as the velocity of a fluid increases, its pressure decreases. Pascal's Law. | Science of the Morse Code Telegraph and the importance of S.O.S | Sir Issac Newton's First, Second, and Third Laws of Motion. |
| Solar collectors are different from PV Cells, they transfer the actual heat of the sun to, for example, a hot water heater. | A molecule is the smallest unit of a substance that shows all the properties of that substance. |
| Some chemical reactions are fast, some are slow. | Atoms are one of the smallest particles of matter. | Molecules are made of atoms, and polymers are made of strings of molecules. |
| An element contains one kind of atoms. A compound contains two or more. | A gas in a sealed jar exerts pressure equally on all the sides of the jar. |
|
| The nucleus of an atom consists of protons which carry a positive charge. These protons attract the negatively charged electrons. | Each molecule of water is made up of two hydrogen atoms and one oxygen atom. | Some substances can bond with water, some cannot . |
