…showed last 75 words of 423 total…Ask students which objects weigh more than others and why.
Expected conclusion: Students will know the difference between the weights of certain objects and how this weight differs when other variables are added.
Evaluation/ Assessment: Students can be given objects to make predictions about. After they have made their predictions, they can see if their predictions are correct by using the balance.
Applications to real life: Insight into weights and measurements of small everyday things.
