No Barriers
In the tub with no barriers, the first one there are 2 waves. When the 2 waves meat they just go right through each other, but if you are making a wave from one side stronger than the other one, the stronger one would eventually just go right through. In the second one, it's just the same, but the disturbance is being caused in other directions. In the last one, the disturbance is being caused in the middle of the tub. That means that no matter what, the waves will travel in all directions.
1 Barrier
In the first picture with one barrier the tub is being shacked, from one side to the other. The water is bouncing on the barrier from one side to the other. The water that isn't blocked is just going from one side to the other, and then makes a slight bend. In the second one the water just bounces of again, but the water that bounced on the barrier first is ahead of the other part of water. The last one is just the same a the first just in a different position.
2 Barriers
In the first picture there are two barriers. the water in the middle just goes right through, and the water by the barriers just keep's bouncing off. In the second picture the barriers are forming a square. There is no movement in there because the waves caused by a disturbance can not get in. In the last picture of all, it's mostly just the same like the first one with 2 barriers.
You worked so well during this lab activity and the illustrations you made demonstrated the interactions between waves in various situations. Good job. The only thing missing here is the conclusion regarding the guiding question. You made excellent observations and analysis of the data.
