Hello!
Thought i'd share a lesson that my students enjoyed and the teachers did as well. This lesson was about making predictions. The first part of the lesson was in the classroom. I started by explaining to the class what a prediction was. I had the students make some predictions about what they would eat for lunch, what the weather would be like the next day, and what time the sun would set that night. Once they got the hang of that, I told them we would be doing 2 science experiments and we would need to make some predictions. (If you want to introduce other words such as hypothesis you could, but I tried to keep it simple!) I gave them the handout, and together we looked at the experiments. I had the actual materials ready to show them, and used them as props to help demonstrate the method. Then we talked about the predictions for the experiments. For experiment 1, they cirlce A or B. For experiment 2, I wrote their predictions on the board and they chose one to write on their sheet. (Before I made photocopies, I drew a picture for each of the steps in #2 so they had a visual.)
Once you have explained both experiments and made predictions, it is time for the fun part! Take the students outside and perform the experiments. I let the students poke some pencils through the bag after they watched me do it a few times....if you joke about doing it over someone's head they love it too! Talk about the result, and whether their prediction was correct or not.....have the students write a sentence about it on their paper.
So...Experiment #1....you just fill the ziploc (ziplocs are preferred because it has to be good quality plastic) 3/4 full of water, seal it. Gently poke a pencil in one side and out the other.....the water shouldn't leak!! If you want to explain why, tell them the plastic stretches until the pencil goes through, and the plastic is then tight to the pencil and there is no room for the water to escape (teachers might need to help translate)
Experiment #2....The eggs must be HARD BOILED with the shells taken off. You light a piece of paper, drop it into a glass bottle, and then immediately put the egg on top. In a few seconds, the egg should be sucked into the bottle! Again, you can tell them that the fire burns oxygen (they know the word O2) and when it is burned, the air sucks the egg in.
These experiments are easy to find on the internet if you want a better explanation!
Have fun!
