Body Systems & Teamwork
These two body systems work together to bring in oxygen from the air and deliver it to cells throughout the body.
What are the Respiratory System and Circulatory System?
This primary energy source is required by plants to initiate the process of photosynthesis.
What is the Sun (or Solar Energy/Light Energy)?
This simple sugar molecule is broken down during cellular respiration to release usable energy for body cells.
What is Glucose (C6H12O6)?
When thermal energy is added to a solid, its particles move faster and its kinetic energy does this.
What is increases?
Thermal energy (heat) always naturally transfers in this direction between two objects of different temperatures.
What is from the warmer object to the cooler object?
When you touch a hot stove, this system sends a signal to your brain, which then tells your muscles to pull your hand away.
What is the nervous system?
These two chemical substances are the required inputs (reactants) for photosynthesis.
What are Carbon Dioxide (CO2) and Water (H2O)?
In addition to glucose, cells require this gas to perform cellular respiration.
What is Oxygen (O2)?
This phase change occurs when a liquid loses thermal energy and transforms into a solid.
What is freezing (or solidification)?
When you hold a warm mug of hot chocolate, your cold hands warm up because thermal energy flows from the mug into your hands.
What is Thermal Energy Transfer (or Heat Transfer)?
Shivering when you get cold is an example of your body attempting to maintain a stable internal balance, known by this scientific term.
What is Homeostasis?
These two products are generated by a plant during photosynthesis.
What are Glucose (C6H12O6) and Oxygen (O2)?
Fill in the missing word: Cellular respiration breaks down glucose using oxygen to produce carbon dioxide, water, and ____.
What is Energy (or ATP)?
During vaporization (boiling or evaporation), liquid particles absorb thermal energy and change into this state of matter.
What is a gas?
If you drop room-temperature metal spoons into a bowl of ice, explain which way thermal energy moves.
What is from the warmer metal spoons to the colder ice?
After you eat a sandwich, these two body systems work together to break down the food and transport the nutrient molecules to your muscles.
What are the Digestive System and Circulatory System?
This green organelle inside plant cells is responsible for capturing light energy to make sugar.
What is the Chloroplast?
The ultimate source of energy stored inside food molecules originally came from this source.
What is the Sun?
Describe what happens to the speed and arrangement of water molecules when liquid water cools down and freezes into ice.
What is particles slow down (kinetic energy decreases) and lock into a fixed, rigid structure?
Between a small cup of hot water and a giant swimming pool filled with warm water, this one requires much more total energy input to change its temperature due to its greater mass.
What is the swimming pool?
During an illness, infected cells release chemical signals. Name the system that transports these signals and the system that carries white blood cells to fight the infection.
What is the Circulatory System?
Animals release carbon dioxide into the air during respiration. Explain how plants cycle this carbon back into food for the ecosystem.
What is by taking in carbon dioxide during photosynthesis and converting it into glucose (C6H12O6)?
If a runner hasn't eaten all day and feels exhausted, explain why their body cells are unable to perform cellular respiration efficiently.
What is because the cells lack glucose (food molecules) needed to produce ATP/energy?
During a phase change (like ice melting into liquid water), thermal energy is added, but this measurement remains constant until the change is complete.
What is temperature?
Explain what happens to the kinetic energy of ice particles when an ice cube is placed in a warm drink.
What is kinetic energy increases as the ice absorbs thermal energy from the drink, causing the particles to move faster?
