RIVER EXPERIMENT
Mrs. Greazel: Since we're studying rivers in Science, we decided to make our own rivers. This enabled us to observe the characteristics of a river, as it flows. Last week 5 groups of students created and tested models of rivers.
Faiz: This week we tried changing different variables in our rivers to see how these changes would impact the shape of the river. The different variables that we changed were the riverbed (rocks,sand, dirt and pebbles together instead of just sand),slope (different degrees of steepness and no slope), the riverbank (a rock border vs. aluminum sides) , obstructions, and different water presure/level.
Mrs. Greazel: We behaved as scientists do by creating hypotheses, testing them by only changing 1 variable at a time, observing the results, and recording the results. I asked questions to get the kids thinking during the 1st trial, and the kids quickly took over asking questions to help each other make detailed observations.
Jameson did an excellent job recording our trials. Take a look at the videos and ask your child what observations they made. Ask them how the different variables changed the flow of the river, and what they noticed about erosion ad deposition during the trials.
