Ideas and evidence
• Collect evidence in a variety of contexts.
• Test an idea or prediction based on scientific knowledge and understanding.
Plan investigative work
• Suggest questions that can be tested and make predictions; communicate these.
• Design a fair test and plan how to collect sufficient evidence.
• Choose apparatus and decide what to measure.
Obtain and present evidence
• Make relevant observations and comparisons in a variety of contexts.
• Measure temperature, time, force and length.
• Begin to think about the need for repeated measurements of, for example, length.
• Present results in drawings, bar charts and tables.
Consider evidence and approach
• Identify simple trends and patterns in results and suggest explanations for some of these.
• Explain what the evidence shows and whether it supports predictions. Communicate this clearly to others.
• Link evidence to scientific knowledge and understanding in some contexts.
Humans and animals
• Know that humans (and some animals) have bony skeletons inside their bodies.
• Know how skeletons grow as humans grow, support and protect the body.
• Know that animals with skeletons have muscles attached to the bones.
• Know how a muscle has to contract (shorten) to make a bone move and muscles act in pairs.
• Explain the role of drugs as medicines.
Living things in their environment
• Investigate how different animals are found in different habitats and are suited to the environment in which they are found.
• Use simple identification keys.
• Recognise ways that human activity affects the environment e.g. river pollution, recycling waste.
States of matter
• Know that matter can be solid, liquid or gas.
• Investigate how materials change when they are heated and cooled.
• Know that melting is when a solid turns into a liquid and is the reverse of freezing.
• Observe how water turns into steam when it is heated but on cooling the steam turns back into water.
• Explore how sounds are made when objects, materials or air vibrate and learn to measure the volume of sound in decibels with a sound level meter.
• Investigate how sound travels through different materials to the ear.
• Investigate how some materials are effective in preventing sound from travelling through them.
• Investigate the way pitchdescribes how high or low a sound is and that high and low sounds can be loud or soft. Secondary sources can be used.
• Explore how pitch can be changed in musical instruments in a range of ways.
Electricity and magnetism
• Construct complete circuits using switch, cell (battery), wire and lamps.
• Explore how an electrical device will not work if there is a break in the circuit.
• Know that electrical current flows and that models can describe this flow, e.g. particles travelling around a circuit.
• Explore the forces between magnets and know that magnets can attract or repel each other.
• Know that magnets attract some metals but not others
