Robots are machines that can do work on their own. Read about all of the different and exciting jobs robots do in our communities.
Many technologies are made up of different parts that each perform a certain job. This basic introduction to systems will show you how all the parts work together as a group to complete a task.
Read about the invention of certain tools, and how they have been improved over time to become the technology we use today.
Energy powers the things that make our lives easier, safer, and more fun. Read about the Earth-friendly tools that are used to gather energy.
Read about the different tools of technology we use throughout our day. Think about which kinds of technology you use yourself.
Technology is the name we give to the tools that help make work easier, safer, or more fun for us to do. Learn about the basics of technology and how it improves our lives.
Some objects must be made of certain kinds of materials to make them work the way they should. Read about how the properties of different materials, such as their hardness or weight, help make an object fit the job it is made for.
Did you know that an object can only move if a force is placed on it? Read about pushing and pulling - the forces that make objects move - and what happens when you change the strength or direction of a force.
Could an engineer that builds roads fix a problem on an airplane? Read about how different kinds of problems are solved by different kinds of engineers.
We can all make good choices to do our part to care for Earth. Read about the importance of reducing, reusing, and recycling, as well choosing items that can be used over and over.
The only way we can learn about dinosaurs is by studying their fossils. Read about how comparing fossils shows us how different dinosaurs moved, what foods they ate, and how they protected themselves.
Engineers don't give up when they fail to solve a problem. Discover why learning from mistakes helps guide engineers to find the best solution.
Read about some of the things that engineers design, such as bridges and water systems, to improve life in our communities.
Different problems need different solutions, but engineers follow the same steps to solve them. Discover the path engineers take to find new solutions or improve old ones.
Engineers often look to nature to help them solve problems. Read about human technologies that have been inspired by animals and plants.
Engineers build models to help them test how well their solutions will work. Read about how testing small-sized models helps them spot mistakes, make improvements, and create the best solution possible!
Did you know that a problem can have many different solutions? Read about how an engineer finds the best solution to solve a problem or meet a need.
Read about the kinds of jobs that people do as engineers, and how they use math, science, and creative thinking to solve problems.
Earth was a lot different when dinosaurs were alive. They lived alongside many ancient mammals that can no longer be found. Incredible changes on Earth have left us with fossils that scientists use to learn more about the ancestors of today's mammals.
Earth was a lot different when dinosaurs were alive. Lush, deep forests once grew where we now have frozen oceans and glaciers. Even though there have been incredible changes on Earth, there are some ancient plants that are still living today!
Earth was a lot different when dinosaurs were alive. Scientists study important clues that were left behind to learn what kinds of dinosaurs lived where, what they ate, and how fast they could run. Even though there have been incredible changes on Earth, there are still dinosaur relatives living today!
Earth was a lot different when dinosaurs were alive. Back then, the world's oceans were ruled by large sea monsters. Even though there have been incredible changes on Earth, there are still sea monster relatives living today!
We measure time in minutes, hours, days, weeks, months, seasons, years, and in historical dates. We talk about mealtimes, bedtimes, school times, holiday times, and good times. We also use words such as past, present, future, next, last, before, and after. This engaging book looks at human time as well as how time passes in nature. Time is about change. How do animals and plants sense changes in time? What changes do we see in nature throughout a day, month, and year?
