Susan needs to measure the volume of lemon juice, water, and sugar for an experiment. Which piece of equipment will she use?

• Beaker

• Erlenmeyer Flask

• Graduated cylinders

• Test tubes

Resistance to force measures assessment to texture, and stretchability measures:

• elongation

• lightness or darkness

To measure volume accurately in a beaker, Ben places the beaker on a level surface at eye level. An additional step that is necessary with a graduated cylinder is to look at the:

• bottom of the meniscus

• middle of the meniscus

• top of the meniscus

• widest part of the meniscus

• Irradiation

• Ohmic processing

• Ozonation

What is an advantage conventionally produced foods have over organically produced foods?

• Fewer chemicals are used

• Their availability

• They reduce pollution

• They have more nutritional value
