I introduced our Earth's system unit by first having students brainstorm what they already know about earth (land and water). I then introduced the concept of change. Change means becoming different over time!
We talked about how some changes happen slowly, while others happen more quickly. We then went outside to make some observations (after coming up with an hypothesis first!) about changes we can observe in nature.
We observed things that change in: size, color, number, place, and shape. We also noticed that most changes we could observe happen slowly.
Below you will also find some pictures from a fun math facts game that we played during re-teach time.
