In science, we have been learning about forces. Last week we investigated air resistance and its effect on different sized parachutes.
Each group made three parachutes with string, playdoh and a black plastic bag. Each parachute was a different size (15cm X 15cm, 30cmX 30cm and 50cm X 50cm). To ensure it was a fair test, the string and playdoh were the same size for each parachute. We only changed the size of the parachute canopy.
Next we dropped the parachutes from the second floor down to the infant corridor. We found out that the smallest parachute travelled the fastest and landed first. The largest parachute travelled the slowest because of air resistance (the size and shape of the canopy trapped the most air which reduced its speed).

Final Group Book Blitz Chain!
We are learning about friction in science. Today we timed ourselves transferring jelly cubes from one bowl to another using two pencils. We then added oil (a lubricant) to the jelly and repeated the task. We discovered that friction between the two surfaces (pencil and jelly) was greatly reduced with the addition of oil/ a lubricant. It proved very challenging to grip the jelly with the oil!
To consolidate our work on lines and angles, we took to the school grounds in search of a different lines (parallel, perpendicular and intersecting) and angles (right, acute and obtuse). Using our geostrips, we discovered lots of lines and angles in our school environment.
