5th Grade: The students have started a new unit entitled "Mixtures and Solutions." We've practiced and discussed different ways of separating mixtures (which are two or more things mixed together). This week, we are investigating solutions, which is a type of mixture where the solid dissolves. We made a salt water solution, then separated it by evaporation.
Key Questions:
- What is a mixture? What are some examples?
- What is a solution? What are some examples? How do you separate solutions?
4th Grade: The students have also started a new unit on magnetism and electricity. This week, we spent a lot of time investigating which objects will stick to a magnet (objects made of iron). We also will be investigating the property of poles and the concepts of "attract" and "repel."
Key Questions:
- What objects stuck to your magnet? Which did not?
- What happens when you bring two magnets together? What if you flip one the other way?
