New ReviewCurriculum resources can be expensive—but not this one. An online textbook offers informational text for a complete high school Biology course. Topics include energy flow, body system, genetics, and evolution.

When studying locations of specific species, interesting patterns emerge. Young scholars discover this as they plot the location of specific species on a group of islands. Patterns emerge as they identify the Wallace Line. They then...

One important skill in analyzing scientific evidence is identifying facts versus opinions. Scholars identify pieces of evidence from the film The Day the Mesozoic Died and then discuss this evidence in small groups at the end of each act...

Why are living things important to the environment? A PowerPoint explains just that as it covers ecosystems and their components, specifically focusing on the types of organisms that live there. Scholars get an introduction to evolution...

Have you ever wondered why some people are lactose intolerant? Participants test simulated patients in a hands-on lab activity to find out! They learn about lactose intolerance by performing an experiment, analyzing data, and drawing...

Bacteria are pesky little organisms that can often easily infect us. But how? Salmonella bacteria literally gets under our skin. Viewers see how the dangerous bacteria protects itself from defense mechanisms inside the cell.

Are sickle cell disease and malaria related somehow? Scholars learn about both illnesses and the hypotheses that they are related. They discuss, view a video, and answer questions to demonstrate understanding. The resource includes an...

Can evolution repeat itself? Scholars analyze amino acid data in two separate populations of mice. They learn that evolution repeats itself, but natural selection prefers some mutations over others in different environments. Analysis...

More than 90 percent of humans' DNA doesn't code for anything! Scholars watch a presentation as they answer questions relating to gene mutations. They read details, watch videos, and view animations supporting the concepts. The questions...

Most fish freeze to death when the water is too cold, yet some fish live in the Southern Ocean where the water is often below freezing. Scholars use two models representing the blood from most fish versus the blood from Antarctic fish....

The proteins inside a cell determine the shape of the cell. While most red blood cells have a circular shape, those with sickle cell take the shape of a sickle. This change in shape causes multiple issues in the system. Scholars solve...

The Hardy-Weinberg principle states that alleles and genotypes remain constant in the absence of evolutionary influences. Scholars complete a simple hands-on activity applying the Hardy-Weinberg principle to sample data. They observe how...

What can fossils tell us about periods of extinction? Young scholars interpret fossil layers to make conclusions about changes in life during different geological time periods. They analyze the fossils for abundance and diversity as well...

Most species of animals include a variety of fur or hair color, but why? Scholars watch a video about a changing environment for mice. As the rocks around them change hues, different colors of mice begin to thrive. Discussion questions...

Compare what shells look like on the outside with what makes that happen on the inside. Scholars begin by sorting an various seashells by their physical characteristics into phylogenetic trees. They then conduct a DNA comparison of...

How does nature select some adaptations over others? Scholars experiment picking up seeds with two different types of tools simulating beaks. After practicing, they experience a drought where one type of seed suddenly isn't available....

On the Caribbean islands, lizards expanded into different niches instead of competing for resources. Scholars discuss and learn from experts in a video how scientists prove the theory. They build phylogenetic trees based on appearances...

Around the world, about 2/3 of adult humans are lactose intolerant. Scholars work in small groups to discuss a few statements about lactose intolerance. Then, they watch a video on the topic and readdress each statement. Whole-class...

Many physicals include a blood glucose test, but what are doctors actually testing? Scholars graph and interpret blood glucose data, allowing them to observe the differences in lactase persistence and draw conclusions. They then connect...

Two fish appear different, but how do scientists determine their genotypes? Scholars practice performing test crosses to determine the genotypes of fish given their phenotypes. They answer in-depth comprehension questions and complete...

Gene switches work similarly to light switches in controlling one feature of their environments. Scholars study the Pitx1 gene in a specific type of fish. They learn the different ways this switch controls various body parts and...

People with the sickle cell trait, but not sickle cell disease, find natural protection against malaria. Scholars consider various combinations of genotypes and environmental factors to determine if children might have sickle cell...

Take your classes back in time. Learners read real historical texts from both Darwin and Wallace as well as an announcement of their findings. Using guiding questions, they make inferences and draw conclusions from the information in the...

What happens when a new predator comes to town? Learners analyze an experiment that studies the effect of predation on selection. They use real data to draw conclusions about the impact a new predator has on a prey species.
