The origin of science goes back centuries and often began with a simple drawing of scientific equipment. The writings and drawings of Leonardo Da Vinci, for example, led to much of today's science and technology---some of his drawings featured the helicopter, revolving bridge and scuba gear. Other scientific equipment such as beakers, pipettes and microscopes often began with a simple drawing---drawings that are easy to do yourself.

Draw a rectangle on its side.
Add two triangles on the sides of the rectangle. Drop three lines down from the corners of the rectangle and connect the lines (this makes the base 3D).
Connect the two triangles at their points and erase the inner lines. Add three small can shapes to the base to make the feet.
Draw a rectangle with a rounded edge on top of the base. Drop lines from the corner and make it look three-dimensional like the base in step 2.
Extend a curved arm up from the base. Place a ball at the top and make the front of the arm straight.
Where the arm curves, draw a second line and connect in the corner. Extend the bottom to make it 3D, and add a rectangle to make the stage.
Drop the corners of the stage down and connect to make 3D (as in steps 2 and 4). Add a cube on the bottom of the stage that connects to the arm base and erase the inner lines.
Add an oval to the front of the ball to make the revolving nose-piece. Place a cylinder on top of the ball to create the body tube and the lens (eyepiece). Draw a squat can shape on the base underneath the stage to make the light source and add an oval on the flat side of the arm.
Turn the oval into the coarse adjustment knob by drawing another can shape. Add three cylinders of different lengths to the nose-piece to become the objectives.
Draw a circle on the stage to let the light through. On either side of the circle, draw a long triangle to make up the stage clips. On the sides of the cube, add two cylinders to make the fine adjustment knobs. Draw a rectangle on the base for the on/off switch to complete.
Trace the drawing with pen and erase the pencil when the ink is dry.
Draw an oval.
Find the center of the oval and draw a cylinder on top of the mark.
Connect the sides of the oval to a point about 1/3 of the way down the cylinder.
Erase all of the inner lines (except for the oval) and draw a line parallel to the side of the beaker. On the line, draw four lines of the same size. Between those four lines, draw three smaller lines in between to make a "measurement line."
Trace the drawing with a pen and erase the pencil when the ink is dry.
Draw a thin rectangle.
Place a half-circle on the left end of the rectangle.
Attach a triangle on the right end of the rectangle. Place a long skinny rectangle on the tip of the triangle.
Erase all of the inner lines.
Go over the drawing with a pen and erase the pencil when the ink is dry.
