Autumn 1

This term Year 4 are covering the topic - Animals Including Humans.


The children have learnt about the digestive system, the parts of our bodies that make up this system and the functions of each part.  They have also covered the difference between carnivores, herbivores and omnivores. We have studied the teeth in our mouths and are conducting a scientific investigation to discover the effects that different drinks have on our teeth. (we decided to put hard boiled eggs in jars rather than actual teeth as there were no volunteers).


Here is a photo of the investigation so far ...

Can We Identify Different Minibeasts for a Witch's Potion?


After reading 'Room on the Broom'  by Julia Donaldson we decided to help the witch make her magic potion.


Children left the classroom and armed with a 'pooter' and a 'magnifying glass' went in search of different minibeasts.

Children worked in pairs looking under rocks and logs, in bushes and trees to find a minibeast.  When they found a minibeast the children used their pooter to collect it for investigation.

Once children had a minibeast they used a magnifying glass to study it closely and draw an accurate picture so that they could identify what they had found. (All minibeasts were returned to the location that they were found)  


Back in class children used their picture to write a description of their minibeast identifying the number of legs, whether it had wings or a shell etc.

Finally children used a classification tree to identify the minibeast that they had found


 No animals were harmed in the making of this lesson! 

Does the Size of the Canopy Affect How Quickly a Parachute Falls?


After helping the witch to make her magic potion we decided to make the characters a parachute to save them if they fell off the broom again.


Children learnt how a parachute works by experiencing air resistance first hand.  Children ran across the playground holding large sheets of fabric to feel the force of air resistance against the fabric.

Children then witnessed the force of air resistance in action in the hall with an actual parachute. 

Investigating Air Resistance

Back in class children worked in groups to investigate the question.  They made three parachutes each with a different sized canopy to test.

To ensure that it was a fair test children used the same length of cotton and the same size paper clip on each parachute,  they also dropped each parachute from the same height and timed each parachute three times to make sure there were no mistakes.


After the investigation we discovered that the size of the canopy did affect the speed that the parachute falls, the larger the canopy the slower the parachute fell.  We decided that this was due to the larger surface area and that the larger the surface area the greater the air resistance.
