Derek the scuba diver comes to visit!

Today we had a very special visitor!  We had been wondering how people could go swimming with whales and dolphins..so Derek came into our classroom to answer our questions!
Derek showed us his real scuba diving equipment.  He told us how we can breathe underwater if we use a special tank full of air and a regulator (a type of hose with a mouth piece).    He told us that when you breathe underwater you make lots of bubbles!  We told him that we saw a manta ray playing in the bubbles in the diving video.   Derek had a special jacket which had buttons on it.  One button filled the jacket with air so he could float, the other button let the air out so he could sink!
Derek also told us that you need a special licence to go scuba diving to make sure that you know how to keep safe underwater, and also to keep the animals safe.  Finally, we all had a chance to examine the equipment.  Thank you Derek!
