Last week marked the final week of our nonfiction unit in reading and writing. Because the students enjoyed doing the EAL News production, we recorded another newscast, this time about the world’s strongest animals and what it is like to be a firefighter. Enjoy!

Today’s lesson was about floating and sinking. We started the lesson discussing that some objects float, or stay on or near the top of water, and some objects sink, or fall to the bottom of the water. Whether something floats or nots depends on a number of factors. The students shared that they thought it had something to do with the object’s shape, whether there was air inside, how heavy the object was and whether it was flat or not. In order to investigate further, we decided to experiment!
Our science questions was: What objects float or sink in water?
I provided a variety of different objects: paper clip, cork, wooden block, sponge, plastic fork, small clip, small rubber ball, metal block, foil ball, foil piece, chess piece, plastic game piece, balloon and eraser.
The students chose eight objects and wrote down their predictions about whether the object would sink or float. They were then given their own bowls of water and tested their chosen objects and recorded the results.
The students loved dropping the objects into the water and checking whether their predictions were correct or not. I asked them at the end to wrote down anything they were surprised at. One student wrote, “I was surprised that sometimes the plastic fork sink and sometimes it float. When you put it in gently it float and when you drop it fast it sink.” I guess it doesn’t just depend on the objects shape, heaviness or whether it had air inside or not.
Here are some of the photos from the lesson:
The lastest unit in Second grade is Kitchen Chemistry. The students are learning that there is MATTER all around us and that all matter can be categorized as either a SOLID, LIQUID or a GAS. They are learning how to describe matter based on the different PROPERTIES.
Something we investigated in the EAL room was how to describe different matter by their properties. A property describes how somethings looks, feels, smells, sounds like, tastes or acts. The students were given different objects and they had to identify what material they were made out of and whether they could rip, bend, squash, stretch and twist. I thought I had tricked them by giving them a Romanian Leu note. These are made of plastic and are supposedly indestructible. But alas, no, Imri was able to rip it in two!
