This week we have been learning about perimeter and how to find the perimeter of different shapes. We know that you had to add each side of the shape to find the total perimeter. We went outside and in groups, measured the perimeter of lots of different object around the school. We measured the ping pong table, school table, football table, the hopscotch marking, the stage and even the whole perimeter of the adventure playground. We used metre rulers and cm rulers to find the perimeter in cm and m.
Today we looked at the different bones that make up the skeleton. We then used all kinds of foods including broccoli, carrots, beans, spaghetti and mushrooms to construct the skeleton. We then used our knowledge of the bones to label our skeletons. We tried hard to make sure each of the skeletons were clear- some of them even managed to keep their funky hair dos! With the majority of the food ending up on the floor... but a successful day of construction!
First of all we have been discussing the function of the lungs and some facts about our lungs. We had a tournament to see who had the biggest lung capacity. We measured the circumference of the balloon and the largest length of string was the winner. Aidan was our champion! Safe to say we were all blown out after this.
Today we looked at a microscopic image of blood and then made a blood bottle. We found out that blood is made up primarily of plasma, red blood cells, white blood cells and platelets. We also know what each of the functions are! From this we made our blood bottle where we used Cheerios, marshmallows, fabric, water and red food colouring. We might have been a little short for marshmallows in the end...
Today we looked at our heart and its functions; we also made a replica of it to show what happens when blood enters the heart. We used straws as veins and arteries and glued them onto our bag, this made the different chambers of the heart. Then, we put straws into our bag and used our breath to slowly inflate the bag, like the blood would to the heart, and watched it fill up from the right side first and then moving to the left for the arteries to push the blood around the body.
On Monday the whole school had the opportunity to climb inside the Science Dome. We climbed inside the mouth and were greeted by dim lights and projections. Once inside the dome, we carried out a number of activities to do with the digestive system. We even made poo!! We spoke about the food groups and how the digestive system works. A great end to our day!
Today we looked at the digestive system. We recreated how the digestive system turns food into faeces and following our circus theme, we looked at what elephants may eat in the circus and what their faeces may look like. We took it in turns to 'eat' our food and passed it down the esophagus and into the stomach. We talked about the stomach acid and what it does to our food. Next we entered our small and large intestines where all of the nutrients left to be used by other parts of our body. We were then left with our final product which was flushed down the toilet.
This week is Science week where we will be exploring our bodies especially the circulatory and digestive systems. Today we turned our bodies into giants and used our knowledge of math to measure and multiply our own body parts to make ourselves into giants. We then drew some of our gigantic organs, saw where they would go and how they would look against our normal bodies.
Looks like every single member of Year 3 class has a potential future in the circus. I am so proud of every single one of them. They all showed great enthusiasm and gave everything 110%. Lucas Jet was blown away by their abilities and attitudes. Throughout the day they had the opportunity to spin plates, balance feathers, juggle, use a diablo etc and even had the chance to go on the trapeze and show off their moves. What a performance. Well done Year 3 and thank you to all parents who came along and showed your support.
