4 Science Project:
- Instruments that
Extend Our Ability to
The grade 4's used the
internet to research technological
developments that extend our ability to
see. While working in groups, they
chose an instrument, recorded it's
inventor, the date of it's invention, it's
function, and it's use. They also provided
an image of the instrument.

- The telescope was invented in 1621 by Galileo
Refracting telescopes use lenses, and reflecting
telescopes use mirrors to gather and bend light, making
things seem larger. The lenses used in refracting telescopes
are called convex lenses. Convex lenses make things bigger,
- Telescopes are used for beam tests and for research.
They make research easier because they make things
- The X-Ray

Date of the Invention: November 18, 1895
Inventor: Wilhelm Roentgen
How it works: A beam of high energy electrons crashes
into a metal target through the hand, body, or foot, and
produces an x-ray. Radiation (a form of energy) comes out of
the x-ray machine and hits the object, and then the x-ray
film. The radiation can not go through thick objects like
bones or teeth. But it can go through thin objects like
skin. This makes the thin areas black or gray, while the
thick areas stay white. The electrons in a x-ray machine zip
around at thousands of miles per hour.
- What it is used for: To look at bones that might be
fractured or broken, to see something that might have
been swallowed, to examine teeth, to check baggage in the
airport, and many other things.

Date of Invention: The first camera was invented in
Inventor: George Eastman
How it Works: Basically a camera is dark box that holds
light sensitive film at one end. Light enters a hole through
a glass or plastic lens, and exposes the film to make a
picture. On the back of the camera an image is always upside
down after passing through a camera's lens.
- What it's used for: A camera is used for taking
photographs and pictures of things so you can show other
people what you wanted to share. You have to develop and
pick up your pictures at a store. At home you can look at
your pictures, and show or give them to other people.
After that you have to put new film in and take more
pictures or photographs. Two neat types of cameras are a
Polaroid and a digital camera.

A periscope is like a telescope but a periscope has some
angles to it. There are two mirrors in a periscope at a 45
degree angle. A periscope helps you see around walls,
corners, and over stuff. A periscope is very helpful. Most
submarines use periscopes to see over water. The person who
invented the periscope was Arthur Davidson on October 2,
1917. The periscope works by reflecting light off of two

- Date of invention: eye glasses were first made
in 1284 in Italy.
Inventor: Salvino D'Armate
How it works: Eyeglasses work by changing the
direction of the light so that you can see the images
much clearer . The more light that bounces off the
lenses, the better the focus, and the more clearly a
person can see. Lenses are made from either glass or
plastic. Glasses work by helping people to see better.
Some people use eye glasses if they can't see far or
close objects. People also wear glasses outdoors to block
What it is used for: Eyeglasses are used for improving
eyesight - either seeing long distance or close up. Some
eyeglasses are used for fashion and to protect the eyes
when working. Sunglasses help protect eyes from the sun's

- Date of invention: 1625
Inventor: Galileo Galilei.
How it works : Microscopes work by using a combination
of different lenses and a light source. The lenses are
convex (curved outward). The lens closest to the object
being viewed is the objective lens. The other lens is the
eyepiece, and is used to magnify the image formed by the
objective lens. The total power of the microscope is the
product of the magnification of the two lenses. For
example, a ninety power microscope means that at the
clearest focus, the object being observed is about ninety
times its original size.
What it is used for: Microscopes are used for
enlarging germs and other small items that the human eye
can't see. Doctors use microscopes when they look at

Binoculars were invented in 1894 by Carl Zeiss.
Binoculars are made of two telescopes mounted together
side by side, one for each eye. All binoculars have these
- an objective lens that creates an upside down
- a set of prisms that turns the image right side up,
- an eyepiece that magnifies the image.
Binoculars can help you see things closer up. The process
by which this is done is by utilizing curved glass lenses
and multiple lenses within the frame to magnify the subject
as it passes through to the next lens.
Binoculars are usually used for hunting, bird watching,
spying, and sometimes just to enjoy looking around.
