Exploring Science: Fun Facts and Concepts

What are the four types of teeth in humans?

• Wisdom Teeth

• Fangs

• Bicuspids

• Incisors, Canines, Premolars, Molars

• Cuspids

What is the main function of molars?

• The main function of molars is to grind and chew food.

• To absorb nutrients from food.

• To support the structure of the jaw.

• To produce saliva for digestion.

Name the three states of matter.

• vapor

• mist

• plasma

• solid, liquid, gas

What happens to water when it freezes?

• Water turns into steam when it freezes.

• Water expands and becomes less dense when it freezes, forming ice.

• Water evaporates completely when it freezes.

• Water contracts and becomes denser when it freezes.

In a solution, what is the substance that dissolves?

• solute

• solvent

• precipitate

• suspension

What do we call the substance that is dissolved in a solution?

• emulsion

• suspension

• solvent

• solute

How do leaves help plants adapt to their environment?

• Leaves help plants adapt by optimizing photosynthesis, regulating water loss, and adjusting to environmental conditions.

• Leaves do not play a significant role in plant adaptation.

• Leaves are mainly responsible for root growth and stability.

• Leaves primarily serve as a food source for herbivores.

What is photosynthesis?

• Photosynthesis is the process by which green plants convert light energy into chemical energy in the form of glucose.

• Photosynthesis is the method by which plants absorb carbon dioxide from the soil.

• Photosynthesis is the process of respiration in animals.

• Photosynthesis occurs only in the presence of water and soil nutrients.

Why do some plants have thick leaves?

• To store water and reduce water loss.

• To increase photosynthesis efficiency.

• To attract pollinators more effectively.

• To provide shade for other plants.

How do roots help plants survive in dry areas?

• Roots absorb nutrients from the air, preventing water loss.

• Roots grow only in the topsoil, limiting their access to moisture.

• Roots produce flowers that attract rain clouds.

• Roots access deep moisture and store water, helping plants survive in dry areas.
