PHYSICS
This force is what makes your feet stick to the ground and keeps the Moon in orbit around Earth.
What is gravity?
This is the term for a solution that has a pH level below 7.
What is an acid?
This system in the human body is responsible for transporting nutrients, oxygen, and hormones to cells and removing metabolic wastes.
What is the circulatory system?
This part of the human body has the most bones.
What is the hand?
I have keys but no locks. I have space but no room. You can enter, but you can’t go outside. What am I?
What is a keyboard?
The process where organisms adapt to their environment and evolve over time can be explained using principles from biology, genetics, and geology. What is this process called?
What is evolution?
This form of energy is stored in a stretched rubber band and is released when the band snaps back.
What is elastic potential energy?
This type of chemical bond involves the sharing of electron pairs between atoms.
What is a covalent bond?
This term refers to the passing of traits from parents to offspring through genes.
What is heredity?
This type of precipitation occurs when raindrops pass through a layer of freezing air near the ground, turning them into ice pellets.
What is sleet?
I’m not alive, but I grow. I don’t have lungs, but I need air. I don’t have a mouth, but water kills me. What am I?
What is fire?
This science studies the Earth's atmosphere and is crucial for understanding weather and climate patterns.
What is meteorology?
This type of energy is due to the motion of an object and is often calculated as ½ mass times velocity squared.
What is kinetic energy?
This process involves the breaking down of a compound into its elements using electricity.
What is electrolysis?
This process occurs in the mitochondria and involves the conversion of glucose into ATP, releasing energy for cellular activities.
What is cellular respiration?
This phase of a star's lifecycle occurs after it has exhausted its nuclear fuel and before it becomes a white dwarf, neutron star, or black hole.
What is a supernova?
I am often found in space, and I am created when a massive star runs out of fuel and collapses. I have gravity so strong that not even light can escape me. What am I?
What is a black hole?
Scientists are using this combination of chemistry and physics to develop new materials with special properties, such as superconductors that work at higher temperatures.
What is materials science?
This telescope, launched in 2021, has provided stunning new images of distant galaxies and stars.
What is the James Webb Space Telescope?
Scientists are using this method to capture carbon dioxide from the atmosphere and store it underground to combat climate change.
What is carbon capture and storage (CCS)?
This mRNA-based technology, used in the COVID-19 vaccines, represents a breakthrough in how vaccines are developed and delivered.
What are mRNA vaccines?
This mysterious particle, which makes up most of the universe's mass, has never been directly observed and remains one of science's greatest puzzles.
What is dark matter?
I am invisible, but you can feel me when I move. I am measured in units of pressure and am essential for weather patterns. What am I?
What is air pressure?
When a new type of material is created to be lighter yet stronger than steel, what property, often studied in chemistry and physics, is being optimized?
What is tensile strength?
This phenomenon, observed in the last decade, is the merging of two neutron stars, which resulted in gravitational waves and a burst of gamma rays.
What is a kilonova?
In 2020, researchers made significant advances in the development of a battery technology based on this element, promising higher energy density and faster charging times than lithium-ion batteries.
What is sodium?
This recent development in genetics enables scientists to revive extinct species by editing the DNA of closely related living animals.
What is de-extinction or genetic resurrection?
This term describes the hypothesis that the universe has been expanding since its inception.
What is the Big Bang Theory?
I can be found in a lab and on a playground. I can make things light or heavy, but I am not a scale. I’m a unit of measurement often used in physics. What am I?
What is a Newton?
This concept involves the bending of light as it passes through different media, like air and water, but it isn’t about refraction or dispersion. It affects how you see a pencil in a glass of water. What is this effect?
What is optical illusion?
