This is a Power Point about how the different material change with temperature exposures.

Here they will find examples of liquid and solid materials and how they change when exposed to heat or freeze.

Also, this lesson includes a video about and experiment and some questions related to it.


One of the pictures was taken from Nelson International Science Student Book 2 by  Anthony Russell.

The worksheet "Study Guide: Chemical Reactions" is a comprehensive overview of chemical reactions, including their types, characteristics, and factors that affect their rates. The worksheet covers a wide range of topics, including:

The worksheet includes a variety of activities and questions to help students learn and apply the concepts covered. Students are asked to define key terms, identify the type of reaction for given equations, and explain the evidence of chemical reactions. They are also asked to design experiments to slow down the rate of reaction.

Overall, the worksheet "Study Guide: Chemical Reactions" is a valuable resource for students who are learning about chemical reactions. It provides a clear and concise overview of the topic, as well as opportunities for students to practice their understanding.

With this activity, teach the different changes in water states (evaporation, solidification,  fusion and condensation).

Student must  cut each example of the second page out and paste it in the correct phase change column.

Have fun and leave a comment if you use it in your class.

Una evaluación para el tema "Cambios en los materiales cuando se aplica fuerza, luz, calor y agua", que se estructura en varios niveles de dificultad, utilizando observación, experimentación y análisis, adecuados para primero básico. 

Are you looking for a fun way for students to identify physical and chemical changes?

This resource is for you! 

This self-checking digital puzzle includes 16 exercises where students have to decide if the change that is described is a physical or a chemical change. 

Every time they answer correctly a piece of a mystery puzzle will appear! If they answer incorrectly, the cell will turn red for students to check their work and try again!

In this master you will find a link for a Google Sheet with the activity for the students. It is self-checking, but you will also have the answers in this master as a reference.

Verb tenses are changes or additions to verbs to show when the action took place: in the past, present, or future. The phrase verb tense is also used for grammatical aspects, which add more details about the duration or time an action takes. When you combine the four grammatical aspects with the past, present and future, you end up with twelve main verb tenses in English. 

CN03 OA01: Observe and describe what plant need to survive, through experimentation, and relate this with its parts and structure. 

CN03 OA: Observe and describe some changes that plants go through during their life cycle (germination, growth, reproduction, among others).

On this project, students get in the role of Scientists and follow every single step of the Scientific Method, in a guided way. They ask a question (guided), formulate an hypothesis (guided) and plant two seeds and expose them to different environments. They have to observe them and record their observations on a chart. Finally, they establish a conclusion and finally they do a final reflection. 

For younger children this project needs to be constantly guided by the teacher.

CN03 OA01: Observe and describe what plant need to survive, through experimentation, and relate this with its parts and structure. 

CN03 OA03: Observe and describe some changes that plants go through during their life cycle (germination, growth, reproduction, among others).

This rubric is to evaluate the project "Growing a Plant", uploaded previously. It is a detailed guideline that shows what is expected from students during this project, and it evaluates the learning process.

CN03 OA01: Observe and describe what plants need in order to survive, and relate this with the stem, leaves and roots.

CN03 OA03: Observe and describe some changes that plants go through during their life cycle (germination, growth, reproduction, among others).

This assessment is to evaluate how students are learning the main concepts of the unit. It includes parts of a plant and their functions, parts of a flower and their functions, reproduction, germination and pollination, among other topics.

Now ED introduces Irregular Sue! Ed (time traveler), realizes he has no power on the verbs. They can't travel to the past! So it's time to call Irregular Sue. Sue changes the verbs by using her bubble gun. 
You don't need to use all the verbs you see in video, but I like the way irregular verbs are introduced.
