We worked in pairs to investigate if we could make a piece of carrot balance on a stick.
We were given an empty bottle, 4 marshmallows, 2 sticks, 2 sweets and a piece of carrot on a short stick.
- The carrot kept wobbling and falling off.
- It was hard to balance the carrot on the right spot.
What we learnt
- If we placed the marshmallows in the same place on each side of the stick, the carrot balanced better.
- It was better when the sticks pointed down because there was more weight on the bottom and it held the carrot still.
- It only worked when the sticks were the same length because then it was equal.
In Year 2, we had a mad scientist day and dressed up. We did 5 different experiments to answer the questions:
- What is the difference between wet and dry sand?
- How can you make water move?
- What are the properties of the materials you can feel and smell in the box?
- Can you sort the materials according to their properties?
- Can you hold a weight using crepe paper?
We all had lots of fun experimenting with the equipment available to answer these questions.
In the afternoon, we had to build a bridge using marshmallows and spaghetti for a car to travel along because it linked to our Brunel topic.
Year 3 and 4.
During Science week, the Year 3/4 team worked together so that all 4 classes mixed up and we completed 4 different experiments, which were really exciting!
The Glass of Water.
One of the experiments involved a glass of water and a piece of cardboard. We filled the glass with water and then placed the card on top. After that, we turned the cup upside down to see what happened. See if you can tell what happened by looking at these photos:
Blowing up a balloon without air
Another amazing experiment we did involved trying to inflate a balloon without us blowing in to it. To do this, we needed Bicarbonate of Soda and Vinegar. We had to be very quick when we put the balloon over the bottle full of the ingredients so no air could get in.
Another experiment involved looking at optical illusions and talking about what we saw in them. After, we made our own colour illusions!
Bicarbonate of soda and Vinegar Bag.
Our last experiment was to make an explosion in a plastic bag using Bicarbonate of soda, vinegar and water.
It was an amazing day! We had lots of fun but learnt lots too! We also enjoyed working with different children from other classes.
Space full of Science!
Because our topic is The Solar System, we made our own solar systems. We got into groups of 8 and decided who would do each planet (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune). We then got a piece of paper and used marbling paints, thinking carefully about the particular colours that we needed for our planet (blue, green, red, yellow, pink and orange). When it was dry, we cut out a circle. Then we embellished our artwork to make it look like the planet in real life by focusing on images of the planets.
Throughout the week, we did a variety of experiments. The experiments we did were called; After Image, Bird in a Cage, Hole In Your Hand, Look into Infinity, Spot the Distance and Spin the Rainbow.
In English, we wrote up some explanations of what you need to do and what happened. Here are some explanations below:
Because we use two eyes, our brains are able to work out depth. In other words, how far away from us something is, or how far one thing is from another.
Photographs are 2D images and therefore, if you take a photograph with infinity focus, they can be used to trick our brains into thinking one object is larger or smaller than it really is. This is called ‘forced perspective’. We had a go at creating some of these ourselves.
