In this biology worksheet, students examine the internal functions of the human body while considering the factors needed to explain the physiological reactions.

Students name wetland plant and animal life.  In this ecosystem lesson students go birdwatching and interpret native plants through art. 

Seventh graders examine different categories of plant life and their roles as producers of food and oxygen for other organisms. They study the evolution of plants from simple organisms to very complex ones. They look at the different...

Students isolate DNA from different food sources. In this biology lesson, students research DNA extraction. They analyze DNA stands collected from the lab, and compare the differences between each.

Students view objects of various sizes from several viewing distances to discover that their visual field is limited. They record what they see and compare their observations with classmates. They conduct more structured experiments.

Students study the effects of global warming on specific organisms. They research the possible problems global warming is causing.

In this bioluminescence worksheet, students read about various organisms that glow on land and in the sea. They answer three critical thinking questions after reading about these chemical reactions.

Students observe and study mutations. In this mutations instructional activity, students work in groups to complete observation tables of various mutations of the zebra fish embryos. Groups give presentations about their observations.

Students discuss the impact of certain inventions. In this technology activity, students research Thomas Edison and the light bulb on the Internet and discuss how the invention impacted society. Students create their own simple inventions.

Students explore different habitats and the food chains within.   In this food web lesson students construct food chains for different habitats.

Third graders do an Internet search to find out about Galloping Gertie and what caused the bridge to fail.

Students work together to collect soil samples from different locations. In the samples, they identify the macroorganisms and classify them. They identify the conditions that affect how macroorganisms grow. They also analyze and identify...

Learners study about geologists and their job. They also study that rocks are made up of minerals and organic material by conducting an experiment where they create their own "granite" or "coal".

Students practice scientific research skills. In this lesson about science, students gain experience with the following skills: comparison, observation, identification, and data gathering. Students will go from station to station and...

Students investigate how food, clothing and shelter come from soil after they examine soil from their own backyards. They map soils on the color wheel before making glue and soil pictures and tie-dying T-shirts in red soil.

Pupils view satellite pictures of the ocean, and discuss the presence of phytoplankton and the colors of the ocean. Students compare/contrast ocean satellite images with maps and globes, then color world maps to replicate the satellite...

Students complete seventeen question test about food safety which includes matching vocabulary terms, short answer questions and fill in the blank questions. Test is part of the Food Safety Unit produced by the College of Agricultural...

Students classify the characteristics of butterflies and moths moths. In this life cycle lesson, students identify butterflies and moths common in the state of Iowa as well as their characteristics.  Students then learn the proper...

Young scholars observe how to distinguish observations form inferences.  In this examining inferences lesson students list observations relating to the activity and discuss the importance of them. 

Students identify the different types of mushrooms. In this biology lesson, students explore different mushroom experiments they can do at home. They discuss ways to extend sliced mushrooms' shelf life.

Students work together to compare and contrast sand particles. They identify what sand grains are composed of as well. They complete writing activities to complete the lesson.

Students examine the concept of osmosis in relation to dehydration. They identify the function and structure of semi-permable membranes. They predict how certain processes can affect the characteristics of an organism.
