Our second grade scientists made models of plant cells out of Play-Doh. Their models had to contain chloroplasts, cell walls, cell membranes, a nucleus, mitochondrion, and a vacuole. All of the scientists did an excellent job, and made some very colorful cells. Our next task will be to scientifically classify living things!
Some of Martic’s young scientists were hard at work making animal cell models out of plastic bags (cell membrane), JELL-O (cytoplasm), Whoppers (nucleus), and jelly beans (mitochondria and vacuoles). Check out their awesome work!
Today, Second Grade worked on our scientific skills, focusing specifically on observation. Students used hand lenses, their Science Journals, and their senses to identify a mystery object . After careful examination, we concluded that the mystery mineral was actually Pop Rocks!
Yesterday, students were challenged to work in pairs to create a Spaghetti Tower. Their goal was to build the tallest tower they could, that would hold a large campfire marshmallow for 10 seconds without toppling over. However, they had constraints! Students were only allowed 3 feet of masking tape, a limited number of dry spaghetti noodles, and 30 minutes to complete their design. All of the second graders did a fabulous job, and every tower was able to hold the marshmallow for 10 seconds.
We had a great first day in second grade. We made banners about ourselves in reading, constructed spaghetti towers during math, and launched a film canister rocket for science. Also, our class started using ClassDojo to encourage one another other to be bucket fillers! Excited for Friday!
I am thrilled to be teaching second grade at Martic! We are all going to have a great year and accomplish wonderful things together. Below is a link to my Second Grade Welcome Letter. I can’t wait to meet everyone .
