The elements

Use a chemical analysis tool to help sort elements from compounds. Go to another universe where elements have different properties. Test the properties of elements and classify them in a table. Use the properties of known elements to classify others. Position elements in the periodic table. Check properties such as atomic ...

Interactive resource

The elements: mystery elements

Sort elements according to their properties into categories such as non-metal, metalloid, reactive gas or unreactive gas. Position elements in the periodic table according to their properties. This learning object is one in a series of five objects. The series is also packaged as a combined learning object.

Interactive resource

Types of matter: quiz

Test your understanding of the particle nature of matter. From a number of particle-level views of substances, choose the one that fits the type of matter required: solid, liquid, gas, pure substance, mixture, element, compound. For example, distinguish an element from a mixture and a pure compound. This learning object ...

Rock recipes

Explore the different types of minerals inside rocks. See that most rock-forming minerals are made up of just two common elements. Discover that most minerals are made up of the same basic building blocks put together in different ways, and that this can explain some of their properties.

Assessment resource

Types of matter: using particle model: assessment

Test your understanding of the particle nature of matter. Interpret particle arrangements to classify various types of matter: solid, liquid, gas, pure substance, mixture, element, compound. Look at the characteristics of a substance to determine changes to its physical state. Select statements that explain your decisions. ...
