    K–12 Home Science Projects 

    Build a Solar Car, Make Super Bubbles, Experiment with Liquid Density, Egg Bottle in a Trick, Color-Change Chemistry. . . .These are just a few of the many popular science projects available at the website. Created as a science teaching resource for K–12 homeschooling families, Home Science Tools offers hundreds of project ideas and experiments in biology, chemistry, Earth science, and physics and engineering that can be completed at home, for science fairs, or adapted for classroom use. Many of the projects feature videos along with the background information and how-to instructions, however, be aware that grade level information is not included on a project's page. Teachers can evaluate the projects individually, or click on Projects by Grade to determine which activities are an appropriate fit for their students.

    In this activity, students examine pictures of pollen grains representing several species that show the structural differences that scientists use for identification. Students analyze model soil samples with material mixed in to represent pollen grains. They then determine the type and amount of 'pollen' in the samples and, using information provided to them, determine the type of vegetation and age of their samples. Finally, they make some conclusions about the likely climate at the time the pollen was shed.

    Activity takes one to two 45-minute class periods. Materials that are needed are tweezers, pie pans, confetti/paper dots and soil.

    Student teams plan and mount a simulated aid mission to provide supplies and prevent a possible disease outbreak in an area devastated by a major typhoon. Using borrowed military cargo aircraft, they determine what aid supplies are needed, create a load manifest matching the capacity of the aircraft, and plot the route the plane will take to deliver the supplies. Critical to providing useful aid, teams have to learn about the infectious diseases that have occurred (or might occur) as a result of the disaster to determine what the survivors really need.
