Term 2: States of Matter

Half tone purple

Half tone green

WALT: Explore how an understanding of the effects of unbalanced forces acting on an object is the basis for the development of hunting technologies used by Aboriginal and Torres Strait Islander peoples.&nbsp;

WILF: Use the information text to complete the cloze activity.

WALT: To elicit questions about why certain changes occur and whether or not they&nbsp;are easily reversible.

WILF: • observe and record information about some common changes to materials • share and discuss observations.

WALT: Investigate whether states of matter are soluble or insoluble.

WILF: Predict, observe and record if materials are soluble or insoluble.

Half tone yellow

WALT: Describe the physical characteristics of matter when it is affected by physical or chemical factors.

WILF: Investigate the use of chemical changes and their application in everyday life by exploring the recycling process.

Head to Smart Class 4 Kids and read the <a href="https://smartclass4kids.com/changing-states-of-matter/">Changing States of Matter </a>information. Use the information to help you complete the worksheet.

1. Go back and check that you have completed your Science Journal to the best of your ability. 2. If you were absent for a week add the word 'absent' underneath the weekly reading page text. 3. If you are missing something from the group work activities make sure you collect it from a team member and insert it in your journal. 4. Upload your Science BC Journal to Seesaw.

Observation/materials: What changes are occurring? Reversible?

Read the <a href="https://smartclass4kids.com/chemical-change-and-physical-change/">article</a> about chemical and physical changes to matter.

Early finisher can test there knowledge <a href="https://k8schoollessons.com/reversible-and-irreversible-changes-quiz/">here.</a> If you finish this activity there are some more chemical changes test too!

List examples of each. To get started head to the <a href="https://www.generationgenius.com/solids-liquids-and-gases-reading-material/#:~:text=The%20three%20main%20forms%20of,a%20gas%20fills%20its%20container.">Generation Genius</a> website.

WALT: Predict, observe and record variables that can affect the outcome of an experiment. 

WILF: Complete investigation template and reflect on predictions upon observation.

Watch the States of Matter <a href="https://www.youtube.com/watch?v=vNvElea-124">video</a>. Complete the definition table below with your shoulder buddy. There are some examples from the <a href="https://sciencenotes.org/10-examples-of-solids-liquids-gases-and-plasma/">Science Notes</a> website.

Watch the <a href="https://www.youtube.com/watch?v=s4LZwCDaoQM">Recycling Video</a> then complete the activities on the next two pages.

Australian Aboriginal use of Spinifex resin technology <a href="https://www.youtube.com/watch?v=CoMKQww5pq8">video</a>. Complete the cloze activity below after watching the videos.

Spinifex ______________ is a thermoplastic matter used extensively throughout ______________ by Aboriginal people. Both men and women are involved in the _______of the resin. In addition to its more common use as an ______________ for repair purposes, spinifex resin is also used as cladding in ______________ construction, and it can be shaped into objects and ornaments for personal use. While the processing and use of the spinifex resin by ______________ people is reducing, scientific interest in the resin is growing among university academics due to the unique physical and chemical properties of the resin. In the video shows the processing of the ______________ plant, the collection of the tiny resin beads, its heating and compaction into a solid lump of resin with a hot ______________, and finally its use in hafting a stone tool.

WALT: Represent what they know about physical and&nbsp;chemical changes and reflect on their learning during the unit.

WILF: • create a final report of their ‘Mess scene’ findings • reflect on their learning during the unit.

Investigate the Mess Scenes and think about the follow questions: • What can you observe about each example? • What changes have occurred to the original objects and materials? • Do you think the changes can be reversed? Why? How? Why not?

Detective Names:

WALT: Research the difference between the 3 states of matter solids, liquids and gases.

WILF: Define each state of matter and identify examples.

WALT: Investigating changes to state of matter, predicting if the change is reversible or irreversible.

WILF: Use information from the previous experiment to predict the changes to matter.
