Curated OER
Reversible and Irreversible Changes
For this reversible and irreversible changes worksheets, students examine 4 pairs of pictures and identify whether the changes shown between each pair are reversible or irreversible.
Curated OER
Reversible and irreversible changes
Students define the words "reversible" and "irreversible." They complete a worksheet that shows a number of changes. Students must decide which are reversible and which are irreversible.
Curated OER
Reversible and irreversible changes
Students experiment with solids and liquids to find which solids will dissolve in water. This dissolution and mixtures lesson can be completed online or in class as all materials are connected to the lesson plan for both settings.
Curated OER
Reversible/Irreversible changes
Learners observe an online activity where they see some solids dissolving and some not dissolving. In this dissolving lesson plan, students learn which solids will dissolve, melt, and which won't. They will also see which effects are...
Curated OER
Reversible and Irreversible Changes
In this change worksheet, learners look at pairs of pictures that have changed, writing either reversible or irreversible to describe the change that took place.

Equilibria—Gifted and Talented Chemistry
Teaching is a balancing act! Keep things on an even keel with a comprehensive equilibrium lesson plan. The resource covers reversible and irreversible reactions, Le Chatelier's Principle, and the industrial applications of equilibrium...
Curated OER
Different Types of Changes (1.2)
In this recognizing different types of changes activity, students answer questions about such things as reversible change, irreversible process, climatic change, filtration process, physical change, and change in the state of a...
Curated OER
Heating and Cooling Materials
When an object is heated or cooled, a change occurs. Learners will work through this presentation and decide whether or not the changes are reversible. They learn about heating and cooling, then assess changes that have taken place. This...

Chemical Equilibrium
Le Chatelier's interest in thermodynamics and building materials such as cement and plaster led to the Le Chatelier Principle in 1884. Activity 13 in a series of 36 extensively explores chemical equilibrium. Learners read about...
Curated OER
Changing Circuits
Students observe an on-line activity to review the basics of electrical circuitry, then research answers to related questions on-line.In this lesson plan on changing components in a series circuit, students discover how different...
Curated OER
Changing State
Students identify the changing states of water, water vapor and ice in the water cycle They investigate how each of these stages can be reversible. Students complete a worksheet describing the water cycle.
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.
Curated OER
Changing circuits
Students identify that there are conventional symbols to represent the components in circuits. Students use these symbols to draw diagrams of circuits. They are reminded that electric circuits can be drawn in diagrams using symbols. ...
Curated OER
Changing Sounds
Pupils identify how the pitch and the loudness of an instrument can be altered. In this online science of sound lesson, students employ the use of an interactive whiteboard to examine the loudness and pitch of a guitar, drum, and bottle...
Curated OER
Changing State
Students investigate the cooling and heating of water. In this online science experiment lesson, students work in groups to make predictions regarding freezing and boiling points and then test those predictions as they complete the...
Curated OER
Light and Shadows
Students observe and record the apperacne of shadows and how their position and shpae changes during the course of the day. Students measure and record the length oof a partner's shadow at different intervals during the day. In pairs,...
Curated OER
Solids and Liquids
Students investigate what happens to solids and liquids when they change from one form to another. In this states of matter lesson, students work in groups on a virtual experiment that requires them to collect data regarding the melting...
Curated OER
How We See Things
Students explain that when a beam of light is reflected from its surface, it changes direction. In this virtual science experiment lesson plan, students complete an activity that requires them to investigate how flat mirrors reflect...
Curated OER
Changing State
Students participate in an online lesson to investigate the effects of cooling and heating on water.
Curated OER
Grouping and Changing Materials
Students feel and observe different types of materials. Using the internet, they sort objects based on the materials they are made from and justify their reasons for putting it in a certain category. They identify objects that could...
Curated OER
Changing Sounds
Students identify how the pitch of an instrument can be altered. They complete a worksheet by labeling several images in order of pitch and then fill a bottle with water to create a sound that matches a pitch on a drawn card.
Curated OER
Pushes and Pulls
Students discuss and investigate how various vehicles move. In a small groups, students then create a wheeled vehicle and find a way to make it move using various resources provided by the teacher.
Curated OER
Circuits and Conductors
Students participate in an online lesson to explain the conductivity of different materials and the effect of changing the power source.
Curated OER
Forces in Action
Learners ask questions that can be investigated scientifically. They determine how to plan a fair test by changing one factor while keeping other factors the same, to use measurements to draw conclusions and use scientific knowledge to...
