Science KS3 Year 8

Autumn

1st
Rocks
VIDEO HOMEWORK

Students investigate the properties of rocks including pH, porosity and resistance. They explore and model the 3 types of rock, igneous, sedimentary and metamorphic within the rock cycle.

After focussing on weathering and erosion, students finish the topic by examining the role of the fossil record in the development of evolutionary theory and providing evidence for extinction events.

2nd
Periodic Table
VIDEO HOMEWORK  

Students study scientific theeory on matter from Aristotle to Mendeleev through to modern understaqnding of super heavy elements.

They chart the development of the Periodic Table and the patterns it demonstrates.

Students investigate the alkaline metals of groups 1 & 2 and the halogens of group 7, giving them an early insight into chemical compounds and bonding.

Spring

1st
Light and Sound
VIDEO HOMEWORK

Energy waves are investigated in this topic using models to demonstrate compressional waves and oscilloscopes to measure wavelength and frequency. The electromagnetic spectrum is introduced, including the uses and dangers of ionising radiation.

The eye and ear structure and how they link to the brain are explored to help understand our perception of light and soun.

2nd
Spring equinox, Easter Life
VIDEO HOMEWORK

Spring is a time when days get longer, temperatures increase and reproduction in plants and animals is evident.

Students begin by investigating the tilt of the Earth on its axis towards the Sun from the spring equinox. They describe how this affects the seasons and has led to seasonal dormancy in deciduous woodlands. They investigate the role of hibernation and the ecology of woodland flowers.

Students follow the reproductive cycle of frogs in the science garden pond over the half term.

Summer

1st
Plant and Animal Cells
VIDEO HOMEWORK

Students compare plant and animal cells from microscope slides they prepare themselves. Structure and function is explored including how different cells act together in organs.

From this students investigate the structure of flowering plants. They dissect a flowering plant to follow the movement of water, minerals and sugars to each cell along the vascular system.

The dissection also looks for energy storage in tubas and bulbs as when as the male and female reproductive organs in the flower.

2nd
Forces and Fluids
VIDEO HOMEWORK

Gravity and magnetism are amongst the forces explored as students carry out a series of experiments to explore motion and resistance to motion. The pushing force of propulsion is explored and students are asked to devise a way of ensuring cars and rockets travel in a straight line.

Comparisons are made of body weight on the Earth, Moon and Mars are linked to planet size and the gravitational force exerted.

The effects of forces on fluids in hydraulic systems are explored for their real world applications.

Each module is assessed by; a short written test, verbal progress assessment or a project assignment.
