SCIENCE GUIDE 2026
◉ inquiry-based activity
Answer: starts by posing questions, problems or scenarios—rather
than simply presenting established facts or portraying a smooth
path to knowledge. The process is often assisted by a facilitator.
◉ net force
Answer: sum of all forces acting on an object. A net force is capable
of accelerating a mass. For instance, if the wheels of a car push it
forward with 5 Newtons and drag is 3 Newtons , the net force is 2
Newtons , forward.
◉ potential energy
Answer: Potential Energy is any type of stored energy. It can be
chemical, nuclear, gravitational, or mechanical.
◉ chemical energy
,nuclear energy
electrical energy
Answer: Chemical energy is stored in the bonds between the atoms
in compounds. This stored energy is transformed when bonds are
broken or formed through chemical reactions.
Nuclear energy is the stored potential of the nucleus of an atom.
Most atoms are stable on Earth; they keep their identities as
particular elements, like hydrogen, helium, iron, and carbon, as
identified in the Periodic Table of Elements. Fission & Fusion
Electric energy is to the kinetic energy of moving electrons, the
negatively-charged particles in atoms.
◉ Energy transformations
Chemical - mechanical - thermal - heat energy
Answer: Think of when you're hungry. When you eat a piece of bread
to satisfy this hunger, your body breaks down the chemical bonds of
the bread and uses it to supply energy to your body. In this process,
the chemical energy is transformed into mechanical energy, which
you use to move, and which we'll cover in more detail in a moment.
It also transforms it into thermal energy, which is created through
, the metabolic processes in your body to generate heat. Most of the
time, chemical energy is released in the form of heat, and this
transformation from chemical energy to heat, or thermal energy, is
called an exothermic reaction.
◉ kinetic energy
Answer: Kinetic Energy is found in movement. An airplane flying or
a meteor plummeting each have kinetic energy. Even the tiniest
things have kinetic energy, like atoms vibrating when they are hot or
when they transmit sound waves. Electricity is the kinetic energy of
flowing electrons between atoms.
◉ Methods of heat transfer
Answer: conduction, convention, radiation
◉ Heat transfer by conduction
Answer: requires some sort of material to facilitate the heat transfer.
◉ Which of the following is the best conductor of heat?
Answer: aluminum
◉ Which of the following is the worst conductor of heat in the
group?
Answer: vacuum
