In this science test worksheet, fourth graders complete 41 multiple-choice questions covering a variety of fourth-grade science concepts.

Roll up your sleeves and get a little dirty with this elementary and middle school compost lesson. All you need is a large plastic container, a couple old newspapers, some organic waste, and a few hundred worms and you're ready...

Students play 20 Questions with animal characteristics and then view an animation of how a tadpole changes into a frog. They consider the importance of camouflage to frogs and write out the story of a frog from tadpole to adult.

Students participate in hands-on acticities to understand how native plants and animals arrived on Hawaii from long distances without the assistance of man. They then identify what characterizes a plant or animal as native vs. non-native.

Learners work together to review the concepts of food webs and food chains. They describe the role of plants and animals when dealing with the cycling of energy. They identify any behavioural strategies to help the animals survive.

Pupils observe the pistil growing into a tiny string bean-like seed pod. They then observe the development of the fertilized pods between Day 17 and Day 35 and record their observations by drawing and labeling, writing, and graphing. ...

Young scholars take a hands-on approach to explore the world beneath the water in this activity. They examine the creatures they catch to study about the adaptations these animals have that allow them to survive in this harsh...

Test scholars' knowledge of ecosystems with a 20-question pre-assessment. Assessment challenges learners to answer multiple choice questions, read diagrams, and complete charts.

Twenty questions make up an assessment designed to test super scientists' knowledge of ecosystems. Scholars answer multiple-choice and short-answer questions about organisms, food chains, energy flow, and more.

Students study the interdependence of an ecosystem that allows it to sustain itself. They examine the Western lowland gorillas for an example.

Learners conduct a scientific investigation about organic or inorganic waste.  In this organic or inorganic waste lesson, students create a compost heap to determine the difference between inorganic and organic waste. Learners...

Garbage, recycle, compost: Does it really matter where we put our trash once we are done? By making detailed observations over seven weeks, kids will see which materials break down naturally to become a healthy part of the soil, and...

It's a time of change. A hands-on activity engages young scientists in a lesson highlighting the change of seasons. They brainstorm indicators of season changes in nature and then look for them. Next, they record observations in a field...

Sixth graders explore the concept of biodiversity.  In this biodiversity lesson, 6th graders discover a variety of planets and animals that live in forests, and how a rotting log benefits that environment.  Students also locate...

Searching for simple ways to teach mitosis to high schoolers? Using colored chalk and onion root tips, pupils visually demonstrate what they view when looking through the lens of a microscope. There are also various ways to expand the...

Students explore the forest. In this ecosystems lesson, students rotate through sensory activity centers, brainstorm, and read about temperate forests.

With The Great Kapok Tree, by Lynne Cherry as the hook learners discuss the rainforest, the animals that live there, and conservation efforts. Then, students write a letter to the man in the story asking him not to cut down the Kapok...

Students examine forest food chains and create a forest habitat in the classroom. They are introduced to the concept of interdependence in Nature. They define a simple forest food chain and develop inquiry process skills.

Students determine

Students observe water birds feeding at a local wetland, record what they see, and construct an appropriate menu for a "Waterfowl Cafe." They also play a "flocking" game.

Get your class outside to observe their surroundings with a lesson highlighting weather patterns and seasonal changes. First, learners take a weather walk to survey how the weather affects animals, people, plants, and trees during...

Celebrate the arrival of spring with this fun primary grade science unit. Engaging young scientists with a variety of hands-on activities and inquiry-based investigations, these lessons are a great way to teach children about...

The sun is shining and the birds are singing, what better time to teach young learners about the fun season of summer. In this week-long science series, children learn how the rotation and orbit of the earth influence...

As the days get shorter and a chill enters the air, it's time to start teaching your little ones about the wondrous winter season. Through a series of teacher demonstrations, whole-class read alouds and discussions, and hands-on...
