Waves are the disturbances or vibrations that are caused in a media. It is constantly being created and always traveling through different media. Some waves need a medium (matter) to travel through and some waves can travel in empty space or vacuum.

What are the topics in Grade 7 physics?
In seventh grade, the study of acoustics (sound), optics (light), thermodynamics (heat), and electricity continue the work done in the sixth grade. In addition, a second block of physics focuses on the study of mechanics and the six simple machines.
Does Grade 7 have physics?
Grades 6 to 7—The subject of natural science merges biology, chemistry, and physics.
What are the lessons in grade 7 science?
The focus of Grade 7 Science is to introduce students to a balance of life science, physical science, and Earth and space science. The concepts and terminology associated with Grade 7 Science will be delivered through the contexts of Interactions within Ecosystems, Mixtures and Solu- tions, Heat, and Earth’s Crust.

What are the contents of science curriculum?
The curriculum content is composed of four strands: Living Things, Materials, Energy and Forces, and Environmental Awareness and Care. These strands, which are subdivided into strand units, outline the concepts and ideas to be explored by children as they work scientifically, and are involved in designing and making.
What is science subject?
Science is a universal subject that spans the branch of knowledge that examines the structure and behavior of the physical and natural world through observation and experiment. Science education is most commonly broken down into the following three fields: Biology, chemistry, and physics.
When was SSES project started?
In response to the growing importance of science and gifted children in the Philippines, the Special Science Elementary School Project (SSES Project) was implemented in 2007.
What are 4 types of waves?
- Microwaves.
- X-ray.
- Radio waves.

What are the 6 types of waves?
Usually, waves are around us, they can be sound waves, radio waves, water waves, sine waves, cosine waves, string waves, slinky waves, etc. These are created through disturbance. There are three types of waves.
What are two types of waves?
Waves come in two kinds, longitudinal and transverse. Transverse waves are like those on water, with the surface going up and down, and longitudinal waves are like of those of sound, consisting of alternating compressions and rarefactions in a medium.
What is science simple answer?
Science is the pursuit and application of knowledge and understanding of the natural and social world following a systematic methodology based on evidence. Scientific methodology includes the following: Objective observation: Measurement and data (possibly although not necessarily using mathematics as a tool) Evidence.
Is life a science?
The life sciences comprise fields of science involving the study of living organisms such as plants, animals and humans. While biology remains the centerpiece of the life sciences, technological advances in molecular biology and biotechnology have led to a burgeoning of specializations and new interdisciplinary fields.
How does photosynthesis work 7th grade?
Photosynthesis is a chemical reaction that occurs in plants by using radiant energy from sunlight. In this chemical reaction, carbon dioxide from the atmosphere and water from the soil are combined to produce sugar (glucose) that contains stored chemical energy.
How old are 7th graders?
