In science, we have been working on the units, Matter: Understandings of the physical world are deepened by investigating matter and energy as well as the unit Scientific Methods: Investigation of the physical world is enhanced through the use of scientific methods that attempt to remove human biases and increase objectivity. We learned about waste in nature and how decomposers help waste break down naturally. We worked through our first science investigation. The students formed the question, do all items in nature decompose at the same rate? We went through the procedure of the experiment and identified the variables that should be kept the same and those that should be changed. Each student then wrote their own hypothesis sharing what they believed the rate of decomposition would be. Groups then selected a fruit or vegetable. Next, we created scientific sketches and recorded our observations. We will return to our experiment each week and record our findings.
This week, we recorded our day eight observations. We were quite surprised at how much our fruits and vegetables had already changed. We are a little nervous to see what they will look like in four weeks!
Learning Outcomes:
I can compare the different methods of waste management and discuss their environmental impacts.
I can interpret data collected from investigations.
I can represent evidence from an investigation in a variety of ways.
I can draw conclusions using reliable and valid evidence from investigations.
Questions to ask your child:
What fruit or vegetable did your group select?
What was your hypothesis? Which fruits and vegetables did you think would decompose the fastest?
What variables did we keep the same to help keep our investigation fair and accurate?
What did your fruit or vegetable look like on day eight?
