A few Facts:
Things float because of something called buoyancy. This describes how "floaty" or "Buoyant" something is. Wood floats really well because of air bubbles trapped inside the wood. Materials like rocks, which are just solid and have no air, this means it sinks. Things like this are called DENSE. If something is heavy like a boat, it has to have air in it, in order for it to float.
Task:
Make something that floats! It could be anything, just something lying around your house. Test your invention, by measuring how far it floats, and how much it can carry.
What would you change? : Sail (make the width smaller)
What did I notice? : It went around in small circles
Why did this happen? : I think this happened because the sail wasn't the right size

Kia ora Kiarah,
ReplyDeleteWow, this is a fantastic blog post. Great job completing the Nanogirl challenge for this week. Did you enjoy being an inventor?
I love how clearly you gave your instructions, step-by-step talking about how you built your boat, excellent work!
How did your boat go in the water once you patched up the holes in the straws? It would be awesome to see a video of it floating!
Keep up the excellent work! I'm excited to see your next creations or inventions.

Ka pai on creating an amazing boat! Great thinking on taping up the ends of the straws! That is a great tip that you shared there!
Nice job reflecting on what you did well, and what needs improvements! I also appreciate how you included the facts in your blog post so your readers learn something as well!
Have a go at making the sail smaller, and then measure how far it can travel! Or perhaps see how much weight it can hold!
Pai mahi, Kiarah!!
Ngā mihi nui,
Charlotte :)
