Lesson 5: Matter & Growth

In the inch plant experiment, what was the dependent variable?

• If the plant grew, using the plants weight
• If there was water or not
• That the plants were all kept in the same window
• That the water all came from the same tap

Answer explanation

Dependent = Measured.

In the inch plant experiment, how did we know if the plant grew?

• It increased in weight
• It was older
• It seemed bigger
• It was taller

Answer explanation

Growth = Weight

What factors do plants need to grow?

• Air, light, water
• Light, soil, water
• Soil, air, water
• Water, light, soil

What evidence did we use to determine if a factor (light, air, water, soil) was necessary for plant growth?

• If the factor was there, it grew. If the factor wasn't there, it didn't grow.
• If the factor was there, it grew. If the factor wasn't there, it's still grew.
• If the factor was there, it didn't grow. If the factor wasn't there, it didn't grow.
• If the factor was there, it didn't grow. If the factor wasn't there, it grew.

Answer explanation

Necessary = did not grow without it

What evidence did we use to determine that soil is not necessary for plant growth?

• Plants in systems without soil still grew
• Plants with soil shrank
• Plants couldn't grow without soil
• Plants with soil died

Answer explanation

Plants increased in weight without soil

True or false: When the inch plant increases in matter, it must the matter from either air, water, and/or light

• True
• FALSE

Answer explanation

Matter must come from other matter

How do you know if something is made of matter?

• It has weight and takes up space
• It has color and texture
• It can do work or cause change in system
• You can taste it

Answer explanation

Weight = measurement of matter

How can we figure out if plants get matter from water, air or light?

• By weighing water, air, and light to see if they have mass
• By measuring the temperature of water, air, and light to see if they have heat
• To measure the density of water, air, and light to see if they take up energy

• Assume plants get matter from water, air, and light

Answer explanation

Weight = measurement of matter
