Core Skills Analysis
Science
- Identified how fossils are formed by recognizing that salt dough shapes become preserved in sand, linking to the concept of sedimentary preservation.
- Observed physical properties of the salt dough fossils (hardness, texture) and compared them to natural stone fossils, supporting inquiry into material differences.
- Used the senses (touch, sight) to locate hidden fossils, developing skills in observation and hypothesis testing.
- Learned the basic sequence of fossil discovery: burial, preservation, and retrieval, laying groundwork for understanding Earth’s geological processes.
Mathematics
- Counted the number of fossils found in each session, reinforcing one‑to‑one correspondence and counting to ten.
- Measured the length of the salt dough pieces before burying, practicing non‑standard measurement (using hand‑spans or small rulers).
- Compared sizes of different fossils, practicing comparative language (larger, smaller, longest) and simple ordering.
- Grouped fossils by shape or size, introducing early concepts of classification and sorting.
English Language
- Used new vocabulary such as "fossil," "sediment," "preserve," and "dig," expanding expressive language.
- Described the process of searching using sequencing words (first, next, finally), building narrative structure.
- Answered open‑ended questions about where the fossils might be hidden, encouraging inferential thinking and spoken language development.
- Engaged in a brief oral recount, strengthening sentence formation and storytelling skills.
History
- Connected the activity to prehistoric life by linking the made‑up fossils to real ancient organisms, providing a time‑depth concept.
- Recognised that fossils are clues about past living things, introducing basic concepts of chronological change.
- Discussed how scientists use fossils to learn about the past, fostering an early appreciation of historical investigation.
- Compared the made‑up fossils to museum examples, encouraging a sense of cultural heritage.
Tips
To deepen the learning, set up a mini‑excavation site with layers of colored sand, letting your child uncover fossils at different depths and talk about the order of layers (stratigraphy). Follow with a simple experiment: press a small toy into wet sand, then let it dry to compare natural and made‑up fossils. Encourage the child to draw a picture of the most interesting fossil and write a single sentence about what it might have been when the dinosaur lived. Finally, create a “fossil log” where each discovery is recorded with a date, size measurement, and a short description, reinforcing both scientific observation and early writing skills.
Book Recommendations
- The Fossil Hunters by Stella Blackstone: A story of two children who discover fossils in their garden and learn about the creatures that lived long ago.
- How to Make a Dinosaur Egg by Katherine O'Connor: A hands‑on guide that shows kids how to make and dig up their own salt‑dough fossils, complete with fun facts about dinosaurs.
- What Is a Fossil? by Lisa Stiff: An illustrated, age‑appropriate introduction to fossils, the rock cycle, and how scientists study the past.
Learning Standards
- Science (UK NC KS1): Identify that fossils are remains of past organisms and understand that they are found in sedimentary layers (KS1 Science – Working Scientifically, 1.1).
- Mathematics (UK NC KS1): Count objects, compare quantities, and use non‑standard measurement to compare sizes (KS1 Mathematics – Number, 1.2).
- English (UK NC KS1): Use a range of vocabulary to describe objects and events, sequence actions using linking words (KS1 English – Vocabulary, 1.3).
- History (UK NC KS1): Recognise that fossils give clues about living things in the past and talk about changes over time (KS1 History – Understanding Past and Present, 1.4).
Try This Next
- Create a ‘Fossil Sorting’ worksheet where children match pictures of their salt dough fossils to the correct size category (small, medium, large).
- Design a simple observation sheet: draw each fossil, label its size, and write a single sentence about where it was found in the sand.
- Develop a short quiz with picture prompts: "Which fossil is the biggest?" or "Which one looks like a leaf?" to reinforce vocabulary and comparison.
