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!
Who wouldn't like a robot for a friend? They're strong, helpful, and want to be like us (with a few crazy differences!) See if you'd like any of the robots in this fun rhyming book as a friend.
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?
This fun book is about animal behavior. It challenges students to guess what animals are doing and why. Topics include camouflage and mimicry, color changes, migration, animal senses and adaptations, courtship dances, care from mammal mothers, playing dead, scary body parts, tongue teasers, and some silly stuff to encourage story writing.
Young readers will love learning how different plants and animals move. Sunflowers turn their heads to face sunlight, some plants close their flowers at night, and others move their heads to trap insects. Animals also move in many ways. Animals with limbs walk, run, hop, leap, climb, dance, and crawl. Animals with wings fly, flap, soar, and glide. Animals that live in water swim, hover, dive, leap, porpoise, and breach. Young readers will become aware of the different ways in which plants and animals move, as well as learn new vocabulary about movement through questions and activities.
Animals hide to avoid being eaten or to sneak up on animals they want to eat. This amazing book introduces children to some basic science concepts and vocabulary such as predator, prey, and camouflage. Fascinating photographs feature animals that can change color, or that have different shapes and patterns, so that they can blend into their surroundings. A special section also features animals that do not need to hide. Sharp quills or bright colors warn other animals that these animals would be dangerous to eat.
Young readers are introduced to the many changes children experience in their early years. The simple text takes readers on a journey from the day a child is born through the first six years of life. An interactive activity asks them how old they were when they reached their own growth milestones of first teeth, first steps, and first day of school.
This delightful book teaches readers about the world of baby animals by identifying animals that share the same names. Adorable photos feature pups (baby dogs and foxes), cubs (baby wolves and bears), and kids (baby goats and human children).
This entertaining book teaches young readers about the different body parts they use to move and play. Body parts are labeled on the photos showing how elbows, knees, ankles, and fingers bend.
