3rd Grade Estimating Weight of Matter
Third graders at Varina Elementary are learning how to estimate weight in math (SOL3.9c), and they are studying matter in science (SOL3.3) so today students in Ms. Hambrick’s and Ms. Leo’s classes estimated the weights of different types of matter. First I gave them each a copy of a blank Google slideshow template in Google classroom. I explained the concept, that they would pick a type of matter (solid, liquid, or gas) that they were curious about and estimate its weight. Then we would research its actual weight. With that in mind, I instructed the students to find a background image for their title slide that showed matter. They typed a creative title, changed the font, size, and color, and typed their name in the subtitle. Next, we created a new slide with “Title only” and changed the background color. The students typed a sentence about their object, identifying it as a solid, liquid, or gas and wrote a question for their classmates to estimate its weight. We had to discuss the incredible variety of matter all around so they weren’t copying a few ideas (it seemed like everyone wanted to weigh hoverboards and cheetahs). They came up with some good ideas that even got me curious. How much does a tree weigh? How much does the water in a pool weigh? Once they had their estimation slide finished, we made one more with the answer. Students had to do a Google search to find the actual weight of their object, and we discussed reliable and unreliable results. Finally we published the slideshows and posted the links on Google classroom so they could practice estimating weight with each other’s presentations. You can see them all here.
