This practical task consists of two parts. Students test various substances with hydrochloric acid, iodine solution, and universal indicator, and then complete a table with their observations. The second part requires students to identify four unknown solids using their tests and results from part one.
For this practical task students make a prediction about which lot of ice will melt first. Then students record their observations and explain why one lot of ice melted faster than the other.
For this practical task students make observations about the effect of coloured lights on different coloured objects. Students then draw some conclusions about their findings.
Task: Order fruit according to size and number of seeds, make a generalisation about the pattern and use this to predict whether a fig has small or large seeds. Assessment focus: pattern seeking.
Task: Use information about differences between moths and butterflies to decide which category examples belong to, and identify what evidence was used. Assessment focus: observation, using evidence.
Students are provided with drawings of the main types of fingerprints. Students then make their own fingerprint and those of three other students. They then classify and describe the differences between these prints.
