Nature Science for UASBN 2010


Elementary Science Experiments Made Fun and Easy

Elementary science experiments can be a ton of fun. At this age, there isn't the pressure on the students that there is in the higher grades. Science fair projects are all about fun! Children are naturally curious and full of questions and energy so it shouldn't be hard to get them to come up with a topic. One elementary science experiment the children may enjoy is to see if water always drains in the same direction. They can test this out around the school, in toilets, sinks and drains. All they need to do is grab some paper and a pencil and head off to a washroom to begin. Have them flush the toilet and make note of which way the water drains. Then get them to put a plug in a sink drain and fill it with some water. Pull the plug and have them observe which way the water drains in the sink. Next, if there is a floor drain around, if possible pour some water over the drain and have them observe which way it flows down the drain. Did the water always drain in the same direction?
If this elementary science project isn't for you, you could have the students test different brands of popcorn. In this project, they test to see if different brands of popcorn leave the same amount of in-popped kernels. Have fun!

Easy Elementary Science Projects
Doing easy elementary science projects need not be kept only for science fairs. There are many good reasons why you and your kids should do science experiments all the time.
It gives you and the kids the opportunity to spend some quality time together
Kids love exploring and it is good to use this natural curiosity to teach them basic science without them even noticing.
Science experiments using easy to obtain supplies are also very suitable for homeschoolers.
Our easy elementary science project for today falls in to the category of "fun." You will have to supervise though; otherwise you will have a big mess on your hands!
To start, explain to the kids that the earth consists of rocks, sand, humus, water and air. This is all the "ingredients" necessary for life on earth. Plants, animals and humans all need them in order to be able to survive. In our science project we are going to have a look at soil. What you need:

5 Small clear jars
Water
5 Soil samples from different kinds of soil (go exploring with the kids to find samples in different places)
Labels
A pen
A notebook
Fill your jars halfway full with your soil samples. One kind of soil into each jar.
Mark each jar with a name that will help you remember which soil you placed in which jar.
Fill the jars with water until they are almost full.
You will see that bubbles start rising to the top of the water.
Make notes of all your results, it is also a good idea to take photos of your result if you are doing this as a science fair project or as part of your science lessons for homeschooling.
You will note that the soil that is the most tightly packed will have less air in it than for instance a soil with lots of humus, taken maybe from a flower bed. Do you think plants grow better in well aerated soil or in soil more densely packed? This can be the subject of a later easy elementary science project. Have fun!
