But sometimes we must start very

small

Procedure:1. Make the battery and bulb circuit (see diagram).Have your adult partner help you assemble the apparatus.

2. Use the pencil to draw and color in a thick, dark box on the piece of paper. Make it several inches long and around half an inch wide.

Tip: Make the box as dark as you can — try not to let any patches of paper show through.

Exploring Materials—Graphene

3. Touch the two insulated wire leads to the graphite box. Watch the bulb—what happens?

Record the distance between the two leads and record your observation in the table. Now try moving the leads closer together and further apart.

What differences do you notice? Record your results in the observation section.

Safety note: never use a plain wire to connect the terminals on any battery directly together. This could cause a short-circuit , overheating or even an explosion.

4. Draw some other heavy dark paths that are not straight and check them with your battery apparatus. Record your results in your observation.

Safety note: never use a plain wire to connect the terminals on any battery directly together. This could cause a short-circuit , overheating or even an explosion.

Graphite conducts electricity because it has a large number of delocalized elections, which are free to move, similar to metals.

If this sample was pure graphene it would act like a super conductor at room temperature.

23

Does Size Matter?

In this activity you will learn about how materials and also physical forces behave differently when things get very, very small.

Throw a baseball in the air and you can predict what will happen – it will fall to the ground due to gravity. The diameter of a baseball is about 73 millimeters. What if that baseball were only 73 nanometers in diameter? Would it behave differently? Would gravity be the only force influencing the ball?

We are going to explore this idea… but instead of baseballs, we are going to look at water drops.

23

24

Materials

• A canning jar (pint or quart)

• Ring part of the lid for the jar

• A Styrofoam plate• A ruler• A sharp pencil• Scissors• A pail (optional)

24

25

Procedures

1. Trace the opening of the jar with your pencil on the Styrofoam plate and cut it out.2. Fill your canning jar with water.3. Place your Styrofoam circle into the ring lid and screw it onto your jar.4. Poke a small hole into the center of your Styrofoam circle with your pencil point. Measure and record the diameter of your hole in the data table.

25

26

Procedures (continued)

5. Working over a sink or pail, place your finger over the hole and turn the jar upside down. Ask your adult lab partner for help if you need it. Keep the upside-down jar straight up and down, and hold it steady. Slide your finger off of the hole. Water should not come out of the hole.

26

27

Procedures (continued)

6. Turn your jar upright. Make the hole bigger by pushing your pencil a little farther into the hole and repeat the procedure.Record your observation. Record the diameter of the hole and your observations.

27

28

Procedures (continued)

7. Keep increasing the size of the hole with your pencil and repeating the procedure until the water comes spilling out.Record all diameter measurements in your data table.

Rainbow FilmHow can you make rainbow colors out of clear nail polish?

In this activity, kids use clear nail polish to create a beautiful iridescent pattern on black paper.

Suitable for kids ages 3 and up.

"Developed for the NISE Network with funding from the National Science Foundation under Award Numbers 0532536 and 0940143. Any opinions, findings, and conclusions or recommendations expressed in this report are those of the authors and do not necessarily reflect the views of the Foundation."

47

• Shallow pan• Strips of black paper (Bristol is best, but

construction paper works)• Clear nail polish• Pencil• Place to let paper dry

Materials

48

Preparation: 5 minutes

Activity: 5 minutes

Cleanup: 5 minutes

Note: It takes about 30 minutes for thebookmarks to dry.

Preparation

49

Step 1Use the pencil to write your name on a strip of black paper.

Holding onto one end, slide the paper into the pan.

Make sure it’s completely under water (except for the end you’re holding).

Procedure

50

Step 2Use the brush to drip one drop of nail polish onto the surface of the water.

Watch what happens—the polish instantly spreads out into a thin film!

Procedure

51

Step 3Lift the paper up and out of the water.

The film of nail polish will stick to the paper.

Does the nail polish still look clear?

Procedure

52

The nail polish spreads out into a thin film, which creates iridescent colors on the paper.

The film is only a few hundred nanometers thick.

Light reflected from the upper and lower boundaries of the film interfere with each other to form a variety of new wavelengths –and new colors.

What’s going on?

53

Thin films can reflect light in special ways because they’re only a few hundred nanometers thick.

That’s in the same size range as the wavelength of visible light.

Soap bubbles and oil slicks are some other examples.

How is this nano?
