Year 3 Science

Students will identify and sequence the basic stages of common animal and plant life cycles.

Students will investigate the specific stages of plant growth, including germination, flowering, and seed dispersal.

Students will compare and contrast life cycles involving metamorphosis (e.g., insects) with those involving direct development (e.g., mammals).

Students will examine how physical characteristics (e.g., camouflage, sharp claws, thick fur) help organisms survive in their habitats.

Students will investigate how behaviors (e.g., migration, hibernation, hunting strategies) contribute to an organism's survival.

Students will explore how living things depend on each other and their environment for survival.

Students will conduct experiments to observe how varying amounts of light affect plant growth and development.

Students will investigate how water availability and temperature influence the growth and survival of living things.

Students will explore the role of nutrients and soil quality in supporting plant growth and, indirectly, animal life.

Students will discuss how human activities can positively and negatively impact the growth and survival of other living things.

Students will investigate how natural forces like wind, water, and ice break down rocks and soil.

Students will explore how weathered materials are transported by wind, water, and glaciers, reshaping landscapes.

Students will learn how eroded materials are deposited to create new landforms like deltas, sand dunes, and beaches.

Students will investigate the causes and effects of earthquakes, including plate tectonics and seismic waves.

Students will explore how volcanoes form, erupt, and reshape the Earth's surface.

Students will learn about other rapid geological events, including their causes and impacts.

Students will analyze how the growth of cities and different land uses (e.g., agriculture, mining) change natural landscapes.

Students will investigate the impacts of clearing forests and the importance of replanting trees.

Students will explore how pollution (air, water, land) and improper waste disposal alter landscapes and ecosystems.

Students will learn about efforts to protect natural landscapes and restore damaged environments.

Students will investigate how rubbing objects together generates heat.

Students will explore the sun as a primary natural heat source and how electricity can produce heat.

Students will observe how some chemical reactions and burning processes release heat.

Students will investigate how heat transfers through direct contact in different solid materials.

Students will explore how heat moves through fluids (liquids and gases) by the movement of particles.

Students will learn about heat transfer through electromagnetic waves, such as from the sun or a fire.

Students will test various materials to determine their effectiveness as heat insulators.

Students will explore real-world examples of how insulation is used to control temperature in homes, clothing, and containers.

Students will apply their knowledge of heat transfer and insulation to design solutions for keeping things warm or cool.

Students will learn how to measure temperature using thermometers and understand different temperature scales.

Students will identify and describe various pushes and pulls encountered in everyday life.

Students will investigate forces that require direct physical contact, such as pushes, pulls, and friction.

Students will explore gravity as a non-contact force that pulls objects towards the Earth.

Students will investigate magnetic forces as another type of non-contact force, observing attraction and repulsion.

Students will investigate how friction acts as a force that opposes motion between surfaces.

Students will explore methods to either reduce friction (e.g., lubrication, smooth surfaces) or increase it (e.g., rough surfaces, treads).

Students will learn how to measure the strength of pushes and pulls using simple tools like spring scales.

Students will investigate situations where forces are balanced, resulting in no change in an object's motion.

Students will explore how unbalanced forces cause objects to start moving, stop, speed up, slow down, or change direction.

Students will investigate how simple machines (e.g., levers, pulleys, ramps) can change the direction or magnitude of forces.

Students will explore how sound is produced by vibrations and how it travels through different materials to our ears.

Students will investigate natural and artificial light sources and how light travels in straight lines to form shadows.
