Year 6 Science Assessments and Tracking Objectives covered: Describe how living things are classified into broad groups according to common observable characteristics and based on similarities and differences, including micro-organisms, plants and animals Give reasons for classifying plants and animals based on specific characteristics Identify and name the main parts of the human circulatory system, and describe the functions of the heart, blood vessels and blood Recognise the impact of diet, exercise, drugs and lifestyle on the way their bodies function Describe the ways in which nutrients and water are transported within animals, including humans Recognise that living things have changed over time and that fossils provide information about living things that inhabited the Earth millions of years ago Recognise that living things produce offspring of the same kind, but normally offspring vary and are not identical to their parents Identify how animals and plants are adapted to suit their environment in different ways and that adaptation may lead to evolution Recognise that light appears to travel in straight lines Use the idea that light travels in straight lines to explain that objects are seen because they give out or reflect light into the eye Explain that we see things because light travels from light sources to our eyes or from light sources to objects and then to our eyes Use the idea that light travels in straight lines to explain why shadows have the same shape as the objects that cast them Associate the brightness of a lamp or the volume of a buzzer with the number and voltage of cells used in the circuit Compare and give reasons for variations in how components function, including the brightness of bulbs, the loudness of buzzers and the on / off position of switches Use recognised symbols when representing a simple circuit in a diagram

These dogs are able to sense a variation within their owners and react accordingly, for instance seeking out another human in the case of their owner collapsing into a seizure.We wanted to learn more about how service dogs help their owners on an everyday and personal basis, so we asked several service dog owners to share their stories with us.

The lines of evidence and analysis supporting the mainstream position on climate change are diverse and robust — embracing a huge body of direct measurements by a variety of methods in a wealth of locations on the Earth's surface and from space, solid understanding of the basic physics governing how energy flow in the atmosphere interacts with greenhouse gases, insights derived from the reconstruction of causes and consequences of millions of years of natural climatic variations, and the results of computer models that are increasingly capable of reproducing the main features of Earth's climate with and without human influences.

The team ran a suite of 400 computer simulations incorporating both what is known about how the climate could react to a greenhouse - gas buildup and a wide range of variations in the global economy and other human factors that might affect the outcome.

How much does human global warming add to such natural variations with climate persistence?

He shows how just a 5 % variation in these sources is more than the total annual human production.

She has been informed by many highly competent scientists that are apparently much more qualified than herself in how to separate the short term natural variation from the human change signal based on changes and influences of increased radiative forcing.

It's like saying «well, I want to see how the living human body works, so to simplify my study of the living lungs, I'm gonna take out his kidneys to remove the kidney variations»... you are pulling out part of the very system that you are studying.

Increased understanding about how environmental variations, such as socio - economic disparities, affect human brain development and behavior has significant implications for advancing basic scientific questions such as understanding genetic versus environmental contributions of brain and behavioral development.
