In our class, we made a water cycle. We used cups, plastic wrap, and a rubber band. First, we put hot water in the cup. Afterwards, we put the plastic wrap over the cup. Then we put the rubber band over the plastic wrap. Then we set them close to the window so they could get heat from the sun. Finally, the heat from the water evaporated to the plastic wrap and turned back into liquid water drops through condensation. When the drops got too big and heavy, they fell as precipitation! In our next Science class, we made pictures of the water cycle to show what happens during the water cycle. After we were done, we added some glitter to the rain and snow. The things falling from the clouds are precipitation, the clouds are condensation. First, the water heats up from the sun and turns into a gas called water vapor. The water vapor goes up into the atmosphere that is very cold. When it hits the cold air, it turns back into a liquid and forms clouds, which is called condensation. Once more water comes into the clouds, they get so heavy and can't hold any more water. They let the water go, and it rains, snows, sleets or hails. This is called precipitation. The pictures below are some examples of our water cycles!
Last week we experimented with air through parachutes and syringes! We used a syringe and plunger to see what happens when we push on air. We also tried to see what happens when you prevent air from escaping. We also made parachutes and observed how air resistance makes them work!
This week, we made our own comics using Arthur's Comic Creator. We had to have at least one telling sentence and one asking sentence in our comic. Our sentences also had to start with a capital letter and end with punctuation. We had to learn how to type capital letters and punctuation marks on a keyboard to do this!
Here is an example of one of the comics the students created! Click on the image to see a larger image. We had so much fun making these!
This week we began our Air and Weather Science unit. It is full of experiments, so we are having so much fun! We explored air and what it can do through a variety of objects: a straw, plastic bag, feather, cotton ball, balloon and styrofoam ball. We also tested what happens when you put a vial in a basin of water upside down and then tilt it. We had to figure out how to put a paper towel in the vial and keep it dry while it was underwater!
Take a look at some pictures from the first exploration we did!
Here are some questions for students to answer! Leave a comment on the blog with your ideas, and we're going to experiment to find out next week!
