Sometimes it's okay to eat your science experiment. A hands-on activity has pupils create models for algae to learn about its cellular structure. The best part of the experiment? The resulting juice-filled gels are edible—yum!

Organelles, cellular respiration, ATP, and DNA. The passage attached to this life science reading comprehension worksheet is all about cells. After reading about diffusion and osmosis, kids answer a series of questions based on the text.

My, what big energy potential you have! Scholars learn about the energy potential of using algae as a biofuel. A PowerPoint presentation first describes the structure of algae and then how researchers use algae as biofuel to produce energy.

The main characteristics and definitive features of red, green, brown, and 4 other algea are listed along with great photos and examples. The details involved with reproduction styles, and information about traits of each Phyla are...

Learners discuss scientific advances brought about by the Mars Surveyor Space Program which impact on daily life, identify laboratory apparatus like microscopes, slides and coverslips, and use the microscopes to view cells and organisms.

In this cell organelles learning exercise, learners read the structure and function of different plant and animal cell organelles to determine what organelle is being described. Students write in the 15 organelles into a chart.

As an anticipatory set, biologists listen to the story of Ruth Patrick, a scientist who used algae to detect water quality. They observe a demonstration of osmosis and diffusion. In their lab groups, they place Elodea stalks in...

Your microbiologists explore a changing algae population and build an exponential function modeling algae concentration from the description given of the relationship between concentrations in cells/ml and days of rapid growth.

In this cell energy worksheet, students are given clues about the light capturing process in plants and the energy producing reactions in animals to complete a crossword puzzle.

In this biology worksheet, students identify and locate various vocabulary terms pertaining to algae. There are 54 biology terms located in the word search.

Examine cyanobacteria cells as an example of prokaryotes and several other alga as examples of eukaryotes. Future biologists compare the two and notice the absence of nuclei in prokaryotes. These are classic activities for this purpose,...

Seventh graders look up pictures of viruses or pictures of models of viruses. Using pipe cleaners, beads, Styrofoam or other available materials make models of these shapes. They then observe a demonstration to show the effect of Tobacco...

Students observe cytoplasmic streaming in Nitella cells. They examine the conduction of a wave of depolarization across other membranes, such as the axons of neurons. Students predict the effects of sending a small electric current...

Students observe the effects of eutrophication and determine why it is harmful to aquatic ecosystems. They create mason jar ecosystems to observe the growth of algae in pond water. In addition, they observe the effect of introducing...

In this characteristics of plants worksheet, students name two things that all plants have in common. Then they describe how the cell walls and cuticles help plants adapt to life on land. Students also explain the difference between...

Students explore algal blooms.  For this ecosystem and health lesson, students define and describe harmful algal blooms, then discuss ways in which the impact of these algal blooms could be reduced.  Students work in groups to...

For this biology worksheet, students identify and locate various vocabulary terms related to the kingdoms of all living things found on earth. There are 24 biology terms located in the word search.

Learners identify the difference between eukaryote and prokaryotes and examine the structure of bacteria.  In this bacteria activity students examine the different ways that bacteria are classified through an activity. 

In this protists worksheet, students will use idea maps about plantlike protist and funguslike protist characteristics to complete 4 short answer questions.

For this protists worksheet, students will review the different types of protists and the different stages of the protist life cycle. This worksheet has 10 matching questions.

Students study chloroplasts, their structure and evolution.  In this photosynthesis lesson students experiment with polarized light and the production of chlorophyll.

For this environment worksheet, young scholars complete a series of multiple-choice and short-answer questions on organisms, reproduction, DNA, and cell division.

In this sponges instructional activity, students read the information about sponges. Students answer the provided questions about the reading passage. Students color the illustration at the bottom of the page.
