We did ''Boats Afloat'' in GT. On my 15x15 I got my boat to hold 11 pennies. On my 20x20 I got my boat to hold 40 pennies. My 30x30 held 52 pennies. I thought ''Boats Afloat'' was a fun experience I'll never forget.

My GT class did this experiment. My first prediction was 14, but the actual amount was 23. One of my 15x15 tests held 65 pennies(it was my last 15x15 test). My next prediction was 59, but my 20x20 totals were 19 and 34. My last prediction was 79, but my 30x30 results were 58 pennies. This was a great experiment.

When I went to G. T we did Boats Afloat. My 1st one held 7 pennies and I guessed 20. My 2nd one held 63 pennies and I guessed 50. And my last one held 106 and I guessed only 50. I loved doing Boats Afloat.

My G. T. class did this activity. My boat was very big. It held 81 pennies. I predicted 100 pennies. This project was more fun than I thought it would be.

My best boat was a 30 by 30 and I made it look like a giant water rafting boat. It was huge! I estimated it would hold 50 and it held 131! I was more than right! I had a great time doing it and I think YOU should try it too!

We went to our GT classroom and made tinfoil boats. My 15 by 15 centimeter boat held 1 penny. My 20 by 20 centimeter boat held 14 pennies. Lastly, my 30 by 30 boat held 22 pennies. This was a fun project!
