Core Skills Analysis
Science
- H practiced observation skills by carefully noting the appearance changes in the lolly snakes after soaking.
- H applied measurement techniques to quantitatively assess the length of the snakes, reinforcing understanding of using metrics in experiments.
- H learned to formulate conclusions based on experimental evidence, linking changes observed to the conditions applied (soaking in water overnight).
- H engaged in recording scientific data, developing skills for documenting and communicating experimental results effectively.
Tips
To deepen H's scientific understanding, encourage hands-on exploration of material properties by experimenting with different types of substances (e.g., other candies, fruits, or everyday objects) and observing their reactions to water or other liquids. Challenge H to predict outcomes before experimenting to develop hypothesis-making skills. Additionally, introduce simple scientific journals where H can log daily observations over several days for longer-term studies, enhancing patience and data tracking. Finally, incorporate discussions about why the changes occur at a molecular level, suited to her stage, to build foundational concepts about materials and their reactions.
Book Recommendations
- What Happens to a Seed by Anne Rockwell: A beautifully illustrated book explaining the changes that happen to seeds as they grow, tying into concepts of change and observation in nature.
- Science Experiments You Can Eat by Vicki Cobb: This book explores fun food-based experiments, perfect for relating to H's lolly snake activity and extending understanding of materials and reactions.
- The Magic School Bus Wet All Over: A Book About The Water Cycle by Patricia Relf: While focused on water, this book helps explain water’s properties and effects, which complements the concepts seen in H's experiment.
Learning Standards
- ACSSU074: Living things grow, change and have offspring similar to themselves. (Relates to understanding material changes)
- ACSIS086: Safely use appropriate materials, tools or equipment to make and record observations, and measurements using digital technologies as appropriate.
- ACSIS087: Collaboratively and independently pose questions, make predictions and conduct investigations, including fair tests.

- Create a worksheet that prompts H to record initial and final measurements and descriptive observations before and after soaking various objects in water.
- Design a simple quiz to test key concepts of absorption, material changes, and experimental conclusions based on the lolly snake experiment.
