EIGHTH-GRADERS CAN DO EXPERIMENTS BUT STRUGGLE TO EXPLAIN THEIR RESULTS
Exemplifying the richness of the ICT assessment, the series of investigations included in “Bottling Honey” measured both science content and practice. In this task, students conducted simulated investigations of the effect of temperature on the flow of liquids, beginning with simple experiments and progressing to more complex ones. Based on the results shown below, students demonstrated the ability to design experiments and gather appropriate data, but had more difficulty when required to explain their findings.
