Here is an experiment you can do at home! If you film it and then put it on see saw you will get bonus points on the next science test! (If you cant film on seesaw film on phone and email!) Make sure to answer the questions below. (Please complete by Monday November 6th)
The first experiment is a very simple one that shows children how to tell if a chemical reaction has occurred by observing the formation of a gas.
- A bottle
- baking soda
- a balloon
- a funnel
Have the kids place a small amount (a couple tablespoons) of baking soda in the balloon using the funnel. Then have them pour vinegar into the bottle so it is about half full. Very carefully stretch the balloon around the top of the bottle, making sure you keep the balloon down so that the baking soda doesn’t fall into the bottle just yet. Once the kids have formed their guesses have them tip the balloon up to allow the baking soda to drop into the bottle. Make sure they hold the top of the balloon so that it doesn’t come off. Once they have observed the reaction, ask questions.
- What type of reaction occurred?
- How do they know?
- What is inside the balloon?
