Engineering and Design

Scientists observe the world carefully and ask questions about what they see.

An experiment is a test to find out if something is true. You can do experiments at home!

Recording your observations means writing down or drawing what you notice during an experiment.

Tools like rulers, magnifying glasses, and thermometers help scientists measure and observe.

Comparing means looking at two or more things and finding what is the same and what is different.

A prediction is a guess about what will happen. Good scientists make predictions before testing.

Plants need different amounts of water. Test this by watering plants different amounts and watching what happens!

Good scientists repeat their experiments to make sure the results are the same each time.

Using a magnifying glass makes small things look bigger so you can study them closely.

Engineers design solutions to problems. They make things that help people every day!

When scientists test ideas, they change one thing at a time and keep everything else the same.

Making observations means using your senses to gather information about something.

Mirrors reflect light. When light hits a mirror, it bounces off like a ball bouncing off a wall.

The engineering design process: identify the problem, brainstorm ideas, build, test, and improve!

A prototype is an early version of something you are building. Test it, then make it better!

Classifying means sorting things into groups based on their features.

A fair test changes only one thing. If you change two things, you will not know which one made the difference.

Scientists share what they learn so others can build on their discoveries.

A model is a smaller or simpler version of something that helps you understand the real thing.

An investigation is a careful study to answer a question. What would you like to investigate?
