In this Unit we will continue our exploration of matter with Pure Substances, Mixtures States of Matter, and Phase Changes. Students begin by learning how to distinguish between whether a substance is a pure substance (element or compound) or a mixture. Then we will explore the differences between the particles and structure in the different states of matter. I love to show students the cool things that can happen when you adjust the pressure in a gas with a Vacuum Chamber demonstrating Boyle's Law as well as what happens when you adjust the temperature of a gas showing Charles' Law. We end this unit by exploring how adding or removing energy from a substance causes a Phase Change. Students get to know the "how and what" of things that they experience everyday in their normal life. Below are links students can explore to learn more about these topics.

In this unit students are learning about how organisms interact with their environment. We are exploring how photosynthesis helps to transfer energy through food chains, webs and energy pyramids. Students will be conducting an Owl Pellet Dissection as part of their investigation. Below are links related to this unit for enrichment.
For this unit, students are learning how to analyze a change and determine if the substances after the change are a result of a physical or chemical change. Students look for evidence that shows a chemical change has taken place. This is always a fun unit, because of all of the experiments and demonstrations we can do for them to evaluate.
