- 2. A test or investigation done to learn or discover something new. Scientists conduct it to understand how things work or to test their ideas and hypotheses. It involves carefully planned steps and observations.
- 4. A force that pulls objects toward each other. It's what keeps us grounded on Earth and what makes things fall when we drop them. It is why planets orbit the sun and why the moon stays in orbit around Earth. Imagine a force that keeps everything in place!
- 6. An explanation or idea that tries to explain how or why something happens. It is based on evidence and observations. Scientists use it to understand and make predictions about the natural world.
