Learners observe a model of a cell and its chromosomal DNA made from a plastic egg and dental floss. Use this model to illustrate how much DNA is held in one cell.

Somatic Cell Nuclear Transfer (SCNT) is a cloning method that involves transferring a nucleus from a somatic cell of the individual to be cloned to an enucleated egg.

In this activity, learners investigate color vision as well as plan and conduct their own experiments.

In this inquiry-based lesson, learners measure the biomass of trees, calculate the carbon stored by the trees, and use this information to create recommendations about using trees for carbon sequestra

Role-playing the parts of chromosomes and centrioles, learners use large chromosome models and nylon cords (spindle fibers and cell membranes) to walk through the processes of mitosis and meiosis.

In this fun, hands-on autumn activity, learners experiment to discover whether the colored substances in leaves can be separated from the leaves.

In this activity on page 3 of the PDF, learners visualize the relative size and structural differences between microbes that have the potential to cause disease.

In this laboratory experiment, learners explore how effectively different sunscreens protect yeast cells from damage caused by ultraviolet (UV) radiation.

In this activity, learners conduct tests for proteins, glucose, and starch.

In this experiment using sprigs of Elodea, learners will observe a natural process that removes carbon dioxide (CO2) from Earth's atmosphere.

This activity (on page 2 of the PDF under SciGirls Activity: Forensics) is a full inquiry investigation into how hairs from a crime scene are matched to suspects.

In this activity, learners observe what happens when yeast cells are provided with a source of food (sugar). Red cabbage "juice" will serve as an indicator for the presence of carbon dioxide.

In this activity, learners investigate the touch sensory system and discover how to plan and carry out their own experiments.

In this two-part activity, learners investigate buoyancy, density and surface area as well as biodiversity and the relationship between the structure and function of organisms.

In this activity, learners solidify their conceptualization of cells by building a model of a cell in a ziplock bag.

In this activity, groups of learners work together to create edible models of chemicals involved in autotrophic nutrition.

What does it mean to be alive? Is a cactus alive? Is a seed alive? Is the air we breathe alive? What are the necessary characteristics?

In this series of exercises, learners predict the conditions necessary for bacterial growth, test their predictions and at the same time practice the aseptic techniques and safety procedures needed wh

This activity helps learners visualize the Human Immunodeficiency Virus (HIV) by constructing three-dimensional HIV particle models from paper.

This is an activity (located on page 3 of the PDF under Self-Assembly Activity) about self-assembly, the ability of molecules to assemble themselves according to certain rules.
