Exploratorium: the museum of science, art and human perception Make a Bouncing Polymer Ball - Experiment with Polymers Introduction Balls have been toys practically forever, but the bouncing ball is a more recent innovation. Bouncing balls were originally made of natural rubber, though now bouncing balls can be made of plastics and other polymers or even treated leather. The bouncing ball in this activity is made from a polymer. Bouncing Polymer Ball Materials Here's a list of materials you need to gather to make bouncing polymer balls: borax (found in the laundry section of the store) cornstarch (found in the baking section of the store) white glue (e.g., Elmer's glue - makes an opaque ball) or blue or clear school glue (makes a translucent ball) warm water food coloring (optional) measuring spoons spoon or craft stick to stir the mixture 2 small plastic cups or other containers for mixing marking pen watch with a second hand metric ruler zip-lock plastic baggie Let's make bouncing polymers balls...

Ok, maybe you did, but if you're not sure where to start, we've got five really fun experiments that demonstrate the scientific principles of buoyancy, surface tension, density, chemical reaction and non-Newtonian fluid. Best of all, families can do these easy experiments with common, household items. Sesame Street's fuzzy, blue scientist Grover stopped by the #5facts studio to teach us a few things about the scientific method. Looking for more amazing experiments families can do together? Be sure to tweet your discoveries with the hashing #5facts, and subscribe to our YouTube channel for more fun trivia about science, history and pop culture. 1. This experiment is a great way to explain the principle of buoyancy and also to get your kids to voluntarily wash your fruit. What you'll need: Regular orangePeeled orangeDeep bowl or pitcher of water One of these oranges will sink and one will float.
Weird Science Kids Kids Science Experiments - Kids Science Projects including, gravity, lights, floating, sinking, mixing, separating, absorption, magnets, heat, pressure, and getting reactions that are all fun, easy and exciting. Science Fair Projects This is selection of ideas for 1st grade science fair projects with short project descriptions or examples as well as links to the actual science fair projects. Some of this ideas could also be used for 2nd and 3rd grades (and vice versa). Also some second grade science project ideas and third grade project ideas could be used in the first grade so check them out. At this age science projects resemble either simple games or magic tricks. There are few fundamentally different types of science projects for this age and this is how they are sorted. Hobby or Collection. Leaf Collection. The goal of the project is to explain the concept of biodiversity, and find out how many different species of trees and bushes grow in your backyard (your street, neighborhood, nearest forest). When you back home it's time to do some sorting. Collected leaves can be sorted in number of different ways: by shape, by size, by leaf venation and leaf type. To the top of the page. Fossils. So how fossils were formed?
Squirrel Proof Bird Feeder Ever since purchasing my first tube bird feeder I've found myself constantly at war with squirrels. I've tried various strategies; baffles, elaborate ways of hanging feeders from trees, separate squirrel feeders, dousing the bird seed with a hot pepper wash, etc.. all of which proved to be ineffective. I love nature, however it got to a point where 14 squirrels were ravaging the bird seed a day, and I stopped feeding the birds. I thought my bird feeding days were over, however after some much needed additional research I was able to design / build a very affordable squirrel proof bird feeder that really works! Feeder Guidelines: a. b. How this squirrel proof feeder works: Since the feeder should be placed 10ft away from trees, roofs and overhanging branches, and has it's tray roughly 5ft off the ground, squirrels should only have one route to get to the feeder's tray; up the pole.
