On Tuesday 8th October some children went on a science trip to Trinity Biomedical Sciences Institute.
We had a brilliant day. Before we left, we made some predictions for our experiment. When we got there, we were shown into the lab. We felt like VIPs. They told us we were the first children who got to visit their lab. We were given lab coats and gloves to wear as it is important that everything in the lab is kept very clean. Michael had very interesting items on his work desk. It was very messy!
First we practised pipetting liquids into beakers. Then Michael added some dry ice. The dry ice fizzed and formed bubbles which smoked when we burst them. After that we did some races to stack some tips. Next we did an experiment using our thumbs and agar plates. We tested levels of bacteria before and after we washed our hands. Michael sent us some pictures with the results of our experiment. We realised how important it is that we wash our hands!! We were able to compare the results. Some of us had more bacteria than others. Some of us think we even picked up some bacteria while drying our clean hands. We also got to look at some bacteria under a microscope.
We really loved being scientists for the day. Check out the pictures of our experiment.
