The key to great Science is to have fun, play with things and ask questions...
I believe God made us all with a quest for knowledge and answers. However most of us learn to stop asking questions during our formative years... I believe the, "I don't know..." answers from adults in our young lives teach us to accept the things "just as they are, and that things just are..."
Here is an list of links as a complement to your resources:
Junior Science Home Experiments The experiments that can be found at this site are easily added into existing Science programs. These experiments are commonly used within Education Queensland Primary and Middle Schools.
How Stuff Works This is the BEST site in the world for finding out how things work!
Science Toys This is my faviourite Science Site on the web and where I go to get ideas for fun science...
This is a wonderful resource proclaiming research and information on Creation Research
A similar site is found at Defend Your Faith
Another outsanding Site for Older Student is the EXPLORE Site: http://www.exploratorium.edu/explore/
Science Monster This site has heaps of engaging activities and interesting information for Maths as well as Science.
Stellarium
Stellarium is a free open source planetarium for your computer. It shows a realistic sky in 3D, just like what you see with the naked eye, binoculars or a telescope. Just set your coordinates and go. Link to download site...
The Investigative Science Process
When Students have a go at a science Investigations it is good for them to keep records of what they are doing, as this is an important part of the Investigative Science process.Reports are usually set out within the following sections:
Topic, Question, Hypothesis, Method, Observation, Result and Conclusion.
Example done by a Grade 5 student below:
Topic: Recovery Rates
Question: What happens to your heart rate after exercise?
*How long it takes for your heart to return to normal after exercise?
Research: We know the heart speeds up to supply the body with oxygen.
Method:
We will send Donnelly and Sam for a run to speed up their heart rates. We will take their pulse rate before and then after to find their beats/minute for every 30sec after the run.
Hypothesis:
We think that it will take about 1or 2 minutes for Donnellys heart to go back to its normal speed and Sam’s about 4 minutes to go back to normal.
Data collection table:
Don Sam
Report on graph:
This graph shows that Sam’s heart rate went down a couple of beats and then went up again. Sam must have been breathing a lot harder than he normally does. Sam’s heart rate went back to normal after about six minutes.
Donnelly’s graph shows that his heart rate went down quite fast and after about one minute his heart was back to normal.
Results:
Our hypothesis was almost correct.
Conclusion:
We found out that Sam is not as fit as Donnelly we found this out by sending Donnelly and Sam for a run around the top field and when they got back we measured their heart rate. This study shows that not everybody’s heart rate turns back to normal straight away because everybody has different levels of fitness. We could have improved this study by measuring the course that Sam and Donnelly ran. We could also have improved this study by having different people at different points along the run so that Sam and Donnelly would have run the same distance.
Note: the Science and Social Studies assignments will run across 2-3 weeks.This work will need to be monitored by your Parent Teacher and will be marked by your teacher. Please send in your assignments when you have finished.
