Moving and Growing
Students know that humans and some other animals have bony skeletons inside their body. They know that other animals have skeletons on the outside of their bodies. They explain the role of both kinds of skeletons.
Curated OER
Variation
Students participate in an online lesson to reinforce the similarities and differences in plants and animals. They classify living things according to observable characteristics.
Curated OER
Gases Around Us
Learners participate in an online lesson showing that gases are formed when liquids evaporate and that when a gas is cooled, it condenses to form a liquid, and gases move and flow more easily than liquids, and how gases differ from solids.

How We See Things
Students explain that mirrors reflect light. They examine how when a beam of light is reflected from a surface, its direction changes.
Curated OER
Changing Circuits
Students participate in an online lesson to explain how to make bulbs brighter or dimmer in a series circuit by changing the number or type of components.
