Science Week 2019
This year our theme for Science Week is: SCIENCE IS EVERYWHERE!
Based on this we have been doing lots of fun science activities to improve our knowledge and understanding of the world around us, and improve and develop our scientific skills.
Don't forget to try your mini experiments and challenges at home!
Researching a Famous Scientist
As our current topic is 'plants' we decided to research the famous botanist George Washington Carver.
We also wrote some fact files which you can see below.

Science in Class - Plants
Our current topic in science is plants and how they grow. We set up 2 experiments to help us learn about this.
Experiment 1: What do plants need to live?
We know that plants need light and water to live but we wanted to know more so set up an experiment where one plant has light and water, 1 had light but NO water, 1 has water but NO light and 1 has NO light and NO water.
We made predictions about what might happen but we will have to check back in a week or 2 to see what happens.
Experiment 2: What happens if you change the colour of a plant's water?
We know that the stem of a plant transports water around a plant, so we put some carnations in different coloured water to try and change the colour of the flower. Again - this will take a little while so will need to check back for our results!
We even split the stem of one plant in half and put half in red dye, and half in blue. Some of think half the plant will go red and half blue, but the rest of us think it might go purple!
Affinity Water Visit
On Tuesday we had a visit from Affinity Water. First we had an assembly where we learnt all about the water cycle and why it is important to look after our water.
we then had a fun workshop where we completed 2 experiments...
Experiment 1: How can we filter water?
Each group had a jug full of dirty water. We had to use 3 different filters (similar to ones the big water companies use), to try and filter and clean our water. First we filtered it through gravel, then sand, and finally a special carbon filter. By the end the water was much cleaner!
Experiment 2: What can we flush down a toilet?
In our groups we had different materials you mind find in a bathroom: toilet paper, nose tissues, blue paper towel, wet wipes and flushable wipes. We then had to measure out 100ml of water into a pot and place one of the materials in the water. Each pot was then shaken for 20 seconds (to represent a toilet flushing) and we had to see what happened to each material. If it broke into tiny pieces it could be flushed down a toilet - but if not you should put it in the bin.
Interestingly - only toilet paper broke down! Even the flushable wipes stayed whole so you shouldn't flush these - even though the name says you can!
On Thursday we had another exciting assembly! We saw how giant bubbles could be made, balloons could be made to travel in a straight line and even watched an exploding dessert!
Then in our classes we got a chance to learn about stir-thickening materials, which get thicker the more you touch or stretch them, but get thinner if you leave the alone. We made our own in the form of slime! It was great fun but we have to remember the slime rules...
1) Keep slime (and our hands that have touched slime) away from our ears, eyes, noses, or mouths.
2) Always wash your hands after touching slime.
3) Keep slime away from pets and young children.
4) HAVE FUN!
