Make Science an Adventure

Children are natural investigators. They ask questions about everyday things, predict what might happen, and learn by observing the results. In Day 77 of the Solvera369 learning series, young scientists explore two simple activities: testing which objects sink or float and observing how a paper helicopter moves through the air. Both activities encourage curiosity, careful observation, and recording evidence.

Science is not about guessing correctly every time. A prediction is an idea to test. If the result is different from what a child expected, that is still a useful discovery. Encourage children to describe what they observed rather than changing their notes to match their predictions.

Experiment 1: Sink or Float?

Materials: a bowl of water, a metal spoon, a cork or large plastic lid, and a small water-safe toy.

Ask the child to predict which objects will float and which will sink. Test one object at a time by gently placing it in the water. Record the prediction and result in the worksheet. Ask what the objects have in common and whether size, shape, or material might help explain the results.

Science idea: An object’s floating depends on factors including its overall density and the water it displaces. The activity is a starting point for observing patterns, not a requirement to memorise technical terms.

Experiment 2: Make a Paper Helicopter

Materials: paper, scissors, and a paper clip. An adult should help with cutting and folding.

Create a simple paper helicopter using a child-safe template or adult-prepared paper shape. Attach a paper clip at the bottom and drop it from shoulder height in a clear indoor space. Observe whether it spins, falls straight, or moves sideways. Try changing one feature at a time, such as the length of the paper blades, and compare what happens.

Safety: Use scissors with adult supervision, keep the testing area clear, and never drop objects near stairs, people, pets, or fragile items.

Use the Free Day 77 Worksheet

The printable worksheet gives children space to predict, test, and record results for both activities. It includes a results table, reflection questions, and a drawing area for one discovery. Younger children can answer verbally while an adult writes their observations; older children can add a short explanation.

Help Children Think Like Scientists

• Ask an open question before each test: “What do you think will happen?”
• Change only one feature at a time when comparing results.
• Record what actually happened, even when the result is surprising.
• Invite children to explain their observations in their own words.
• Supervise all activities and avoid tasting or mixing experiment materials.

Questions to Discuss

• Which prediction was different from the result?
• What evidence did you observe?
• What would you test next?
• How could you make the test fair?
• Why is it helpful to write down what happened?

Ask, Predict and Discover

Simple experiments help children practise observation, reasoning, vocabulary, and patience. Complete the Day 77 worksheet, talk about the results, and encourage one new question for another day. Every surprising result is an invitation to investigate further.
