GREAT SCIENCE ACTIVITY - Teaches kids about floating and ice melting when it is placed in water.
Make a few boats and float some in cold water and some in warm water to watch the difference in melting times.
The boat may also leave a coloured trail behind as the food dye melts into water (adding extra food dye will make this happen).
SING ROW ROW ROW YOUR BOAT while sailing the waters.
You will need:
- A rectangle shape plastic container
- Coloured paper to make as the sail
- Coloured markers if you would like to decorate the sail (optional)
- Either stapler or a hole punch (to attach sail to straw)
- Food dye (your choice of colour)
- Blu-tack straw to the bottom of the plastic container.
- Fill the container with water about 3/4 full.
- Add a few drops of coloured food dye and swirl to blend colour in.
- Carefully place into the freezer for a few hours or overnight.
- Once completely frozen, cut the coloured paper to a sail shape (triangle), the kids can decorate it if they wish or write a name on the sail for the boats name.
- Then either staple to straw or if its young children using this I prefer to put a hole punch at top and bottom of sail (see picture below) and thread onto straw leaving it slightly lose to represent a sail blowing in the wind.
- Now your ready to sail away!
You can either float the boat in the bath or a large tub much bigger than the boat itself.
It will slowly melt if using cool water.
We also played this in our evening bath once so the water was warm, the boat melted much quicker BUT the kids still had a blast.
