Students make observations about mealworms using hand lenses, rulers, and cotton swabs. Students complete their own mealworm observation chart, then they share their observations with the class. This is one station out of five in an...

Third graders research ecosystems, the work of ecologists, John Muir's contribution to the environment and an endangered species of their choice. They read books, participate in discussions, and write reports.

Students use examples of Joseph Raffael's art of nature to create an all-school mosaic of a tree in spring using clay.

Students know that humans and some other animals have bony skeletons inside their body. They know that other animals have skeletons on the outside of their bodies. They explain the role of both kinds of skeletons.

Students participate in an online lesson to explain the conductivity of different materials and the effect of changing the power source.

Students participate in an online lesson showing that gases are formed when liquids evaporate and that when a gas is cooled, it condenses to form a liquid, and gases move and flow more easily than liquids, and how gases differ from solids.

Learners participate in an online lesson to investigate the effects of cooling and heating on water.

Students practice sorting living things into groups using their characteristics. Using pictures of leaves and animals, they sort them based on their color and shape and write the objects characteristics under the picture. They share...

Students feel and observe different types of materials. Using the internet, they sort objects based on the materials they are made from and justify their reasons for putting it in a certain category. They identify objects that could...

Students explore how a switch can be used to break a circut. Students construct a simple series circuit and use it for a purpose. Students read the "The Lighthouse Keeper's Lunch,or one of the "Katie Morag" stories which clearly shows...

Learners identify how the pitch of an instrument can be altered. They complete a worksheet by labeling several images in order of pitch and then fill a bottle with water to create a sound that matches a pitch on a drawn card.

Learners predict the common classroom items, such as paper clips, chalk, keys, or erasers, that will be good conductors in a circuit. They build circuits using a variety of circuit diagrams to test their predictions.

Students explore animal diets and teeth. In this animal science lesson, students view photos of animals and their teeth. Students identify the type of diet the animal has based on the teeth. Students are introduced to the terms...

Engineering challenges are not just man-made ... nature has its own set of them. A hands-on STEM activity has groups designing a seed dispersal system. Each group can only use one sheet of paper — a tough task!

Third graders use metric measuring for model and actual plan in designing a roof garden. They photograph the process, record results in a journal, and plant seedlings in small containers. Finally, 3rd graders complete an acid rain...

[Free Registration/Login may be required to access all resource tools.] Read about the processes of sexual reproduction in flowering plants, including pollination, fertilization (seed production), seed dispersal, and germination.

Great PDF to teach students about plant reproduction and life cycle. There are many teacher printables.

This landing page includes learning modules on the following topics of: animals, plants, microorganisms, life cycles and reproductions, food chains, habits, humans and the environment, adaptation, inheritance, and evolution.

This customizable digital textbook covers topics related to third-grade science. It is Next Generation Science Standards (NGSS) aligned.

The objective of this lesson is to study the life cycle and structure of plants. Students learn about the concept of classifying objects as either living or non-living by growing plants from seeds, fertilizing them, collecting seed, then...

Learn about the life cycles of plants and animals then demonstrate what you know with activities, a quiz, and related resources.

Kids learn about flowering plants in the science of biology including their life-cycle, structures of a flower, fruit, seeds, and pollination.

[Free Registration/Login Required] This flipchart is based on the Scott Foresman science curriculum developed for third grade. It deals with the topics of plant parts, plant types, and the life cycle that plants go through.
