Two worksheets you can use when introducing weather characteristics and instruments. First, the students have to unscramble the words. Second, they have to read and match each picture with a definition.

OA7: Identify, locate and explain the function of some vital parts and organs of the human body, such as  the heart, lungs, stomach, skeleton and muscles, among others.

With this worksheet, students will be able to apply what they have learnt about the respiratory system and breathing process, by completing a text with vocabulary from the unit.

OA7: Identify, locate and explain the function of some vital parts of the human body, such as the heart, lungs, stomach, skeleton and muscles, among others. 

On this worksheet students will be able to apply vocabulary from the unit on a text. They will also apply what they have learnt about the main organs and processes of the circulatory system.

CN02 OA2: Identify, describe and classify characteristics of invertebrate animals, such as insects, arachnids and crustaceans, among others, and compare them with vertebrate animals. 

This worksheet is a good chance to begin with guided investigation. The idea is for students to research about crustaceans and complete the graphic organizer with the information they find. They don't necessarily need to research in books or in the internet, but they may also use worksheets, videos and Power Points from their 
Science lessons or their Science notebook to look for the information. It depends on the kind of activity the teacher wants to use it for.

CN02 OA4: Observe, compare and contrast the characteristics of different habitats, identifying luminosity, humidity and temperature needed for animals' survival. 

The objective of this worksheet is for students to identify characteristics of different habitats, so they can match each habitat with its description, to solve the crossword.

CN02 OA13: Measure some weather characteristics by building or using instruments such as wind vane, rain gauge and thermometer. 

Before doing this worksheet, it is suggested that, in a previous class, students can build a rain gauge (you can find a video that explains how to make a rain gauge in the following link https://www.youtube.com/watch?v=jwo2XGBABpY ), so students can really experience the use of this instrument. They really enjoy doing it, and they enjoy even more when they use it and learn how much rain fell during a day or during a week.

On this worksheet, students need to look at the weather, measure some of its characteristics and record it on the worksheet.

Objective: Understand the migration process - Understand Cause and Effect.

After learning about animal migration, students identify three causes of this phenomenon, and write them on the graphic organizer.
This worksheet is also useful to work on cause and effect, and relate this strategy to what students are learning in Science.

After learning about animal migration and about some animals that migrate, students can have fun by searching for these animals on this word search. It is a great activity to have as "extra work" for students who always finish activities earlier and need something else to do while the rest of the class finishes the lesson activities.

CN02 OA12: Recognize and describe some weather characteristics and conditions, such as precipitation, wind and temperature, among others, and also some instruments to measure weather.

Students observe the pictures, they recognize different weather conditions and instruments, and complete the crossword with the corresponding words, according to the pictures. They must use vocabulary learnt during the unit.
