    In this lab, students will be able to demonstrate the difference between a physical and chemical change by making ooey, gooey, yet yummy S’mores!

  • Density, Physical Properties, Matter, Observations | Elementary School, Middle School

    Access is an AACT member benefit. Lab: Comparing Density of Liquids & Irregular Solids

    In this lab, students will measure mass and volume, calculate density, and compare the density of given liquids and solids, inferring what causes objects to sink or float in a given liquid. 3-48

  • Periodic Table, Subatomic Particles, History, Introduction, Elements, Atoms, Valence Electrons, Electrons | Middle School

    Access is an AACT member benefit. Project: Elemental Art: A Visual Periodic Table

    In this activity students will research an assigned element of the Periodic Table and then create a poster that visually explains and expresses the element. The final posters can be arranged into a classroom Periodic Table.

  • Physical Properties, Molecular Structure, Polarity | Middle School, Elementary School, High School

    Access is an AACT member benefit. Activity: What Makes Water So Special?

    In this activity, students will become familiar with the special properties of water by completing several activities that investigate the following physical properties/phenomena: cohesion, adhesion, surface tension, and capillary action.
