I made this to introduce vertebrate and invertebrate animals. First, I compare an insect and a mammal (try to elicit the answer). Then, I continue by asking about bones. Do all animals have bones? They'll see some examples. You may try asking for more. 
Send me a message and I'll send you the PPT.

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.

CN02OA09 Observe and describe some water characteristics, such as flowing, adapting, freezing, dissolving; some properties as being transparent, colorless and odorless.
This worksheet was made to identify the water properties. The students have to observe the images and label the pictures using the words from the wordbank.

CN02OA09 Observar y describir, por medio de la investigación experimental, algunas características del agua, como la de: escurrir; adaptarse a la forma del recipiente; disolver algunos sólidos, como el azúcar y la sal; ser transparente e inodora; evaporarse y congelarse con los cambios de temperatura.

I took this idea from Pinterest, it belongs to https://www.teachingideas.co.uk/water/the-water-cycle
Great way to explain the water cycle. You just need a ziploc bag and markers.
My students loved it!

Here is a PPT to help you introduce the subject of human body. It contains some questions you can discuss with the whole group, and explanations about what does each organ do.

I did this ppt with my friend Carmen Ortúzar.

En esta guía de trabajo, los estudiantes refuerzan el contenido trabajado sobre los animales vertebrados, los cinco grupos que existen, teniendo como actividad el clasificarlos. 
Es importante que trabajes con un apoyo visual para complementar la guía de trabajo. 

Con este ticket de salida, tanto el docente como los estudiantes pueden evaluar si conocen las características de los animales vertebrados teniendo que describirlas nuevamente al corregir la descripción que aparece en el texto. 

Está guía de trabajo permite a los estudiantes describir las características de animales que pertenecen a cada grupo de vertebrado.
