Scientific Knowlege

In this step we...Drew a labeled diagram of how our toothpick bridge will be built

In this step we...Put a string around our bridge and added weights to it until the bridge fell or broke to see how much weight it could hold

In this step we...Designed & built a toothpick bridge to hold the greatest amount of weight, but is 30 cm long and spans a 20 cm gap

The toothpick bridge that we built is this

In this step we...Recorded how much weight the toothpick bridge held thought of positives/negatives

The stepwise process where we researched for the best glue by answering the question - which glue was stronger: caesin or flour glue - with an experiment

In this step we...Used toothpicks, homemade glue, and my design we built our toothpick bridge

In this step we... Based on it's performance and other group ideas we thought of ways to improve our design AND places where out design did not need improvement

Stepwise process where we design and build a toothpick bridge

In this step we....Learned about the science of glue, types of bridge designs, and did an experiment to determine the strongest glue

What we gained by performing an experiment on which glue is stronger? Caesin OR Flour glue

In this step we...We did this by sharing our data with the class of how much weight our bridge held
