Science

States of Matter

We have now begun to investigate how substances can change from one different state to another, if heat is either added or removed.  So far we have explored the process of melting and made some predictions as to what we thought would happen if we took some ice-cubes out of the fridge and left them at room temperature.  We used thermometers to help and record our findings with accuracy, and documented our observations.  What do you think would happen if a blue and yellow ice-cube heated up together within the same container?

It's been all systems go as we continue with our exploratory work of the different states of matter in Science.  After discovering more about liquids and solids, we also moved on to learning about gasses.  We discovered that small gas particles can be discovered in amongst substances that appear to be solid, including rocks and grains of sands.  We witnessed in the form of bubbles so knew it must also be present.

This term in Science we are moving onto our exciting new topic where we will learn about and explore the different States of Matter.  We have begun by carrying out a lot of investigative work of categorizing, grouping and finding out about the properties of each of these different states.  So far we have learnt that there are three different types: solids, liquids and gasses.  We have also discovered that it is not always easy to classify all substances under one property, for example jelly and shaving foam, and that we call these colloids!  What do you think? Is jelly a solid or liquid?  Is shaving foam a solid or a gas? Even scientists find this tricky to determine!

Electricity

We then moved on to investigating whether different materials are insulators and conductors.  We made some predictions and then tested our findings.  We discovered that metals are the best conductors and this explains why wires are made from them, we also identified some of the best insulators, including, wood and plastic.  We also discussed that this might be why many plugs and wires are plastic coated.

This term we have started our exciting new topic of Electricity in Science. 

We began by investigating various different inquiry questions, including:

  • Can you make a circuit?
  • Can you unscrew and put a plug back together?
  • What makes the toy move?
  • What makes the buzzer sound?

We managed to complete most of the activities set and discovered the answer to the last two questions was in actual fact Electricity.

 

We have also learnt about the many dangers of Electricity, creating posters to help remind others!

 

We have also moved on to exploring and working out what makes a simple circuit.
