Bowls with water: we used them to trap non-flying insects (the food of some birds).

Camera: we used it to take pictures of birds and identify them.

We made a photographic safari. A photographic safari is when you take a lot of pictures from the same thing. We entered the page www.flickr.com to see some pictures of migratory birds and to upload our pictures. The objective of the activity was to know more about the birds that appear in the area.

investigation because we had to investigate the insects that were on it. We put some recipients full of water and we used nets to catch some insects and observe them trough a microscope. We used magnifying glass to look at the insects more clearly.

We found: Woodlice (bug ball),spiders, wasps, larvaeand mosquitoes.

We observed the grass in the area of experimentation to collect information about the fruits, flowers and insects that appeared there because they are the food of the birds.

We also observed trees and completed the field sheets with the same information.

We collected samples of fruits, seeds, and leaves to investigate them.
