DensityI. Pour all the liquids in separate beakers with

eyedroppers in them and another beaker full of water with an eyedropper.

II. Get a small test tube and drip three-five drops of water into the graduated cylinder.

III. Afterwards drip two drops of the liquid in the graduated cylinder so that it slides down the side.

IV. Check if the liquid goes under or above the water.V. After that empty it out and repeat the steps above for

each of the liquids. This should create a density column.VI. Record your observations

Home

ConductivityI. Put each liquid in separate spaces on the well

plate.II. Then take the conductivity meter and turn it on. III. Check to see that the rods at the end are not

touching. IV. Afterwards place the conductivity meter in each

of the liquid. V. After each Look at the lights in the front and see

the conductivity level on the back. VI. Record the conductivity level.

Color

I. Pour each of the liquids in separate spaces on the well plate

II. Look at the color of each of the drinks.

III. Record your observations.

Home

Optical Properties

I. Pour each of the drink in separate spaces on the well plate.

II. Look at the optical properties of each of the drinks.

III. Check if they’re each transparent, translucent or opaque.

IV. Record your observation.

Home

FlammabilityI. Pour one of the drinks in a beaker about halfway up.II. Light the match by striking it against the side of the

box.III. With the match in one hand, pick the beaker up with

the other hand. IV. Then without blowing out the fire, drop the match

into the liquid. V. Observe what happened. VI. Record your observations. VII. Repeat these procedures for each drink

Home

Reactivity

I. Pour each of the drink in separate spaces on the well plate.

II. Pour less than half a spoonful of baking soda into one of the liquids.

III. Look for any reactions.

IV. Record what you observed.

Flammability Reactivity

Solubility

I. Place half a spoonful of each of the powders in separate spaces on the well plate.

II. Then get a beaker of water with an eyedropper. III. Pick up some water in the eyedropper.IV. Take the eyedropper and drop a couple drops of

water over each powder so you can tell the powder wet.

V. Stir the powder for at least 60 seconds. VI. Check if there is less powder in the water.VII. Record your observations.

Home

Reactivity

1. Place half a spoonful of each of the powders in separate spaces on the well plate.

2. Then get a beaker of vinegar with an eyedropper.

3. Pick up some vinegar in the eyedropper and drop two to four on each powder

4. Use a hand lens in to see reactions in the powder.

5. Record your observations

Melting

1. Tear 5x5 inches pieces of aluminum foil then place on the top of the hot plates.

2. Put a spoonful of each powder on separate hot plates.

3. Set the hot plates to 330°. 4. See if any of the powders begin to melt.

aluminum foil. 4. Then take out a match from the matchbox. 5. Light the match by striking it against the side of the

matchbox. 6. Once the match is lit, carefully put the match on the

powder.7. Record your observations.
