Why do plants photosynthesize? 

To create food and energy.

What is buoyancy? 

An object's ability to float.

What are the materials used and materials produced during photosynthesis? 

Used: Water, Sunlight, Carbon Dioxide

Produced: Oxygen, Energy

200

Label these as a physical or chemical change: Rusting metal,    Chopping fruit,    Burning wood

Chemical.      Physical.          Chemical 

200

Why do objects fall when released? 

Gravity! 

200

What are the 3 kinds of rocks?

Igneous, Sedimentary, Metamorphic

What is the difference between control and experimental groups?

Control groups are your baseline, they provide a reference for your experiment and something to compare to. In experimental groups, you change one variable while holding all else constant.

300

Two identical plants are measured. One is watered consistently, and the other is not. Which one grows more and why?  

The plant watered consistently will grow more because it will have more opportunities/materials to undergo photosynthesis and grow! 

300

Give an example of an Acid and a Base

A bunch of right answers! A: Vinegar, fire ant bites, stomach acid

B: soap, bleach, baking soda

300

What is density?

A measure of the amount of mass per unit volume of a substance.

300

What is sustainability?

Sustainability is the ability to maintain and support a process over time. Environmental sustainability is ensuring different life types can coexist productively to sustain future generations. (Various answers accepted)

300

Describe the Scientific Method

Question, hypothesis, experiments, observations, results, conclusions

Describe the plant growth cycle

Seed > seedling germination > adult plant > pollination > fruit with seeds

What is different about the molecules in solids, liquids, and gases. 

Solids are compact with definite shape and volume. Liquids are less compact and have a definite volume but indefinite shape. Gases are scattered everywhere,  indefinite shape and volume. 

400

Name a conductor and insulator and what they do. (Hint: Why were the circuit boards made with metal?)

Conductor - allow electrons to travel through them, includes most metals

Insulator - resists the flow of electrons, includes plastics and rubber


400

Name two differences between a plant and animal cell.

Cell wall, chloroplasts, shape, vacuole. 

400

What is a non-newtonian fluid? + An example.

A non-newtonian fluid or suspension is a substance that does not follow the matter rules we talked about earlier! It can be a solid and a liquid depending on how much force we apply to it. (Oobleck, Slime) 

500

What is the name of the organelle that plants use to photosynthesize?

Chloroplasts are the organelle! Chlorophyll is the name of the green pigment. 

500

Name 3 kinds of chemical reactions

Possible answers: Photosynthesis, combustion, fermentation, rust, baking, digestion, neutrilization

Name 4 different types of energy.

Possible answers: chemical, thermal, radiant, sound waves, nuclear, electric, mechanical, gravitational, kinetic, potential

500

What gives crystals their shape? 

The interactions of the ions in the crystal. 

Also accepted: How crystals are formed- Magma (liquid rock) cools slowly ⇒ Crystal
