Term 3 Topic Work

2 Comments

Bones

“This term we have been learning about the human body.  We learned about our hands and the tendons used to make them move.

We made hands with string and straws.  We drew around our hands, then taped straws to it and threaded string through so that they could move.”   Elska P4

 

The Digestive System 

“We put crackers, bananas and juice in a bag and mixed it up by squeezing the bag.  This was supposed to mimic the stomach.  Then we put some tights over a paper cup and  poured in the mixture.  Then we squeezed the mixture in the tights.”  Elska P4

The tights acts like the small intestines, squeezing out all the nutrients that the body needs and passing on what our bodies don’t need to the large intestine.  At the end of the task, we emptied the remaining food in the tights into a cup where it was then pushed out as waste.  Some children were delighted to be part of this messy activity, whilst others were glad that it was over!!  It was a great way to visualize what is happening inside our bodies when we eat food.

Time to go to show what happens when we go to the toilet!

 

Sound 

We have been learning about how sound is made through vibrations and how it travels to our ears so that we can hear it.  It was great fun making string telephones to speak with our friends!

We tested to see if we needed the string to be loose or taut.

We’re not sure if the message was able to get passed on here!
Good vibrations…! We tested what happens to the vibrations when we made the ruler longer or shorter.

On the last day of term we had fun making instruments to show our understanding of vibrations and how to change the pitch of sound.

 

A finished guitar, ready to be played!
An “electric” guitar with an amp and an acoustic guitar. Well done boys!

The Results Are In!

Leave a comment

We tested the last of our wind powered cars today.  Some groups needed more time to make slight modifications to their sail or car structure.  As well as engineering skills being developed here, the pupils were working with a partner to share ideas, make decisions and persevere with the task when it didn’t always work first time.  What a lot of learning going on!

Some cars didn’t get finished in time, but those pupils will still get the chance to test their sail making abilities, using a ready made toy car.

As each car was tested. it was lovely to hear the positive feedback given to each group, along with some helpful tips on how to improve on each design.  Some common themes were:

  • Getting the right shape and size of the sail
  • Can the wheels turn?
  • Is anything on the bottom of the car creating too much friction?  We realised that the car would need even more wind energy to help it to move.
  • How the sail was held up – was it secure enough?

With Mrs Smith, the class have been working on their measuring skills and these skills were put into good use for this task!  There were lots of helpful pupils who were keen to read how far each car had travelled.  Very accurate measuring from all!

All of the cars moved when wind energy was provided, even if just a little bit.  However, the most successful wind powered car travelled a massive 1m 80cm!

Even when things didn’t go to plan, it didn’t matter!  We had fun watching the results and learning from the process.  This car was even pushed over by the wind!

Week 3 was another busy one with lots of opportunity to work with others and be creative.

We played a variety of word building games and revised some common high frequency words.  These words are used regularly in our writing, so we will work hard to learn them in many different ways.

Thank you for sending in resources to help with our Rainforest in  a Box project.  We started building them this week and it has been lovely to see so many creative ideas being shared amongst the class.  We plan to have them ready to show parents towards the end of term.

In Maths this week we have been looking at Place Value and how to construct larger numbers.  The class had fun using the Place Value blocks to build models and then work out the value of each model.  It was great to hear the children sharing their thinking and supporting each other to understand.  We will be moving on to comparing numbers and ordering them too.   I’m sure everyone will be keen to challenge themselves with even larger numbers!

We love to hear about any achievements outside of school and this week enjoyed hearing about one P4’s success at a recent athletics competition.  Well done!

 

Class Prize!

Leave a comment

We had our class prize today!  When our peg jar was approaching the finish line, we all voted for what we would like as our prize.  There was no clear winning idea, so we have enjoyed laptop time and crafts.  It has been a lovely, relaxed afternoon full of creativity and fun!

 

I wonder what everyone will vote for next time…?

It has been a busy scientific term in P4/5/6!  Over the past few weeks we have explored all aspects of Light.  We learned about shadows, reflections and how light can bend when it travels through a different medium.

We had fun with a periscope, looking around the room for a secret message being held up on a whiteboard.  This was made possible with the mirrors reflecting the light.

Our camera obscuras showed us how light is reflected into our eyes.  This appears as an upside down image.  Our brain flips this around so that it makes sense to us.  But in this camera, it is projected upside down on to the tracing paper screen.  One pupil decided to do some handstands so that she would be seen the “right way up” in her friend’s camera obscura!  It was lots of fun to experiment with.

 

It’s quiz time!

Wednesday afternoon was spent in P1/2, sharing with them the electrical quiz boards that we made last term.

Each pair supported a couple of P1/2s to try out their quiz and gave them time to explore the electrical circuits used to the play the game.  If they managed to match the question with the correct answer, the bulb lit up!

Everyone in P4/5/6 did so well to explain their quiz and how to use it.  They showed patience and understanding when more time was needed for the pupil to find the right answer.  We would like to thank the P1/2s for having us in their classroom, they listened so well to their buddies and were so enthusiastic about each game they played.

We have missed having these opportunities to mix with other classes and develop important communication and social skills.  We hope to be able to do something like this again soon!

LEGO Renewables

Leave a comment

Emma Chittick, who is a STEM Engagement Advisor for Skills Development Scotland, came in to help us with another STEM wind turbine challenge., but this time we used LEGO!

She set a competition to see which design could generate the most power.  The tricky part was trying to build a strong structure to set the turbine on.  The class also had to consider how they attached their blades and in which direction they were facing.

Everyone was so engaged and worked well on their own or with a partner to complete the task.

Well done P4/5/6!  You did a great job!

Wind Turbine Challenge!

1 Comment

As part of our topic work, we have been learning about Renewable and Non Renewable energy sources.  We discussed the advantages and disadvantages of these and which ones would work best in Shetland.

Last week, we worked in teams to design and create a wind turbine using a selection of materials.  The turbine had to turn when  we used a hair dryer on it and it also had to lift a plastic cup!  Lots of things to consider in their designs!

It was lovely to watch everyone interacting and taking turns to contribute.  Everyone showed consideration towards the ideas shared and compromises were made as to what the design would look like and how it would work.

It was important to try little tests now and again, to check if any changes needed to be made.  Some groups found that when the hair dryer was switched on, the blades of their turbine were not strong enough and required further reinforcement.  Some found that there blades were the wrong size or shape and some discovered that they needed to attach their cup differently so that it would lift without getting tangled in the turbine blades.  Lots of learning going on!

We tested all the designs and everyone had the chance to add their thoughts on what they thought had worked well and what could be done to improve their designs further.  I was impressed with how the children were able to make suggestions in a such a positive, caring and considerate way.  Look out world…some future engineers here!

Animations

1 Comment

During P6 Bikeability time on Monday afternoons, P4/5 have been busy working in small groups to create their own animations.  The plan was to create an animation to help children in the school learn something that they might find tricky.

Our groups are making animations showing alphabetical order, 3 Times Table, Tricky Words and Telling the Time.

We have a couple of weeks left to tweak our animations and then hopefully we can share them with you!

Some people chose to use words and pictures in their animations…

Some groups chose to use items in the classroom to make their animations…

We can’t wait to see the finished products!
