Lean, Mean Information Machine: Using a Simple Model to Learn about Chromosomal DNA
Source Institutions
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.
Kelp Critters
Source Institutions
This marine biology activity (on pages 11-17) introduces learners to kelp (seaweed) forests that grow in the ocean and are home to many species of sea animals.
A Model Parasite
Source Institutions
In this detailed activity (on pages 9-18), learners investigate the body parts of a parasitic ascaris worm by making and dissecting clay models.
Why Doesn’t the Ocean Freeze?
Source Institutions
In this activity, learners explore how salt water freezes in comparison to fresh water.
Chromosome Shuffle
Source Institutions
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.
Life Size: What's in a microbe?
Source Institutions
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.
Clean Water: Is It Drinkable?
Source Institutions
In this activity, learners simulate nature's water filtration system by devising a system that will filter out both visible and invisible pollutants from water.
Living Bones, Strong Bones
Source Institutions
In this activity about engineering, nutrition, and physical activity, learners design and build a healthy bone model of a space explorer which is strong enough to withstand increasing amounts of weigh
Gel Electrophoresis
Source Institutions
In this activity, learners simulate the process of DNA fingerprinting by using electricity to separate colored dyes.
Supporting Structures
Source Institutions
In this activity about living things and gravity (page 5 of PDF), learners design and build an exoskeleton or an endoskeleton for an animal of their own invention.
DNA Jewelry Models
Source Institutions
In this activity, learners construct a model of DNA to better understand the structure of DNA and protein synthesis.
Leaves: Designing Leaf Arrangements on a Branch
Source Institutions
In this hands-on activity, learners investigate the functional design of leaves on a tree.
Slimy Cells
Source Institutions
In this activity, learners solidify their conceptualization of cells by building a model of a cell in a ziplock bag.
Candy Chemosynthesis
Source Institutions
In this activity, groups of learners work together to create edible models of chemicals involved in autotrophic nutrition.
Pollen Tracks
Source Institutions
In this activity (on pages 30-36), learners simulate a dig for ancient pollen, to experience how paleobotanists study fossilized pollen in rocks to learn about early geological and climatological even
Modeling an HIV Particle
Source Institutions
This activity helps learners visualize the Human Immunodeficiency Virus (HIV) by constructing three-dimensional HIV particle models from paper.
Earth Atmosphere Composition
Source Institutions
In this activity, learners use rice grains to model the composition of the atmosphere of the Earth today and in 1880. Learners assemble the model while measuring percentages.
Gene Switches
Source Institutions
In this activity, learners explore how genetic switches function and the role of genetic switches in the process of evolution.
Shoebox Dinosaur Dig Site
Source Institutions
In this activity, (on page 6 of the PDF under SciGirls Activity: Dinosaurs) learners participate in a hands-on fossil excavation.
Size, Scale and Models
Source Institutions
In this activity, learners take measurements and create charts to learn about the size of dinosaurs and their relative scale to humans.
