    Hi,
    If you could obtain owl pellets, you could read Owl Moon and have students use tweezers to open owl pellets (the company that we got them through sterilizes them first) and look for the bones inside, matching them up to those on a chart to see what kind of animal the owl ate. Sounds gross to us, but my students loved doing this. It was part of a bird study.
    Students also had to use different types of tools to imitate birds' beaks to pick up different types of food. For example, they used pliers, tweezers, straws, spoons, icecream scoops, a plastic knife, etc. to pick up rice, puffed cereal... gummy worms were their favorite, especially when they were alllowed to feed a baby bird (another student in the class) by dropping a gummy worm into their mouth. We went on nature walks and looked for food, water and shelter sources and listened for different bird calls.
    We also did magnets, balance and weighing activities and a series of general science investigations. Some good books for balancing and weighing: When the Boat Sank (or a similar title) Mirrette and the High Wire and Mirrette and Bellini cross Niagra Falls. Some of the investigations were: dunking raisins: mixing warm water, vinegar and baking soda and watching the raisin go up and down. Making playdough and experimenting with the consistency. Ocean in a bottle: mixing water with blue food coloring and then adding in baby or mineral oil. Water drop races on a slanted board covered with tinfoil. Does the size of the drop affect the speed? Vascocity: same as water drop race but try it with ketchup, oil, pancake syrup, etc. Finding out what things have water in them: various fruits, potato chips, popcorn, etc. Put them inbetween paper towels and squeeze. The potato chip one you leave overnight along with a paper towel you put water on. Children will see that the wet paper towel dried but the potato chip one didn't because it wasn't water, it was grease. With all of this, making predictions, observing, testing out the hypoth. multiple times, recording and sharing observations. Nature walks followed by leaf rubbings are also fun. There's some book that shows lots of things you can turn a leaf into and then students could draw pictures out of their leaf "base."
    Hope some of this helps, good luck!
