Over the last few weeks, Year 1 have been exploring different scientific experiments within their classrooms. The children have been exploring what it means to create a fair test and how to craft predictions based on prior knowledge.
The first experiment saw the children predicting which liquid would keep an apple slice fresh and crisp for the longest time. They placed apple slices in vinegar, water, lemon juice and milk. After creating a prediction they left the apple slices for 15 minutes and then observed the results. The children were thrilled to learn that lemon juice kept the apple fresh for the longest amount of time! They enjoyed finding out how the colour of the apples were changed due to the liquid they were put in.
The children also took part in an experiment where they looked at different materials to find out which one would help a car travel down a ramp the furthest. Using a fair test, the children investigated using plastic, wood, paper, crumpled paper, bubble wrap and fabric. They wrote predictions based on what they believed would happen and then wrote the results down using a table they had created as a class.
The last experiment saw the children cleaning coins using different liquids to find out which would help remove the dirt the best! They enjoyed watching their teacher scrubbing a penny using a toothbrush. The children made predictions on how well each of the liquids would clean the coins and used a table to collect the results. The liquids used were: ketchup, water, soap, vinegar and coca cola. They were amazed to find out the ketchup and the vinegar cleaned the coins the best.
Keep going with your science experiments Year 1!
