WATCH. Vinegar + Baking Soda + Balloons = FIZZY Fun
TALK. What happens when you mix baking soda and vinegar? Why? What is a chemical reaction? What is it that filled up the balloon? How did it happen? What would happen if you changed the amounts of vinegar and baking soda?
DO. Complete your own vinegar + baking soda experiment.
Remember, the video we watched was a demonstration but we want to create our own scientific experiment so we need to change some of the variables (the parts of the experiment we can control and change).
You need to come up with your hypothesis - what you think will happen when you make certain changes (I predict that adding ... will make the balloon ...).
Complete your experiment and record your results. Was your hypothesis correct?
Kia ora Room 17. How has your week of home mahi been? I have loved seeing all the activities the Kauri team has been engaged with over the week. There is so much to do if you want too! Are you looking forward to the weekend? Do you think it will be the same as the week? What will be different in your house? Last night I made a delicious citrus cake, are any of you baking, if so what have you made? Who ate it?
ReplyDeleteHave a wonderful Rāmere and restful weekend. Maybe we'll be back at school soon??
