An oil spill occurs when seawater is contaminated with oil, either by accident or human error. Oil spills can be massively damaging to marine wildlife and humans if the oil gets into the food chain. After an oil spill, it’s essential to start a clean-up operation as soon as possible. If oil coats birds’ feathers, it reduces their…
What is a Habitat? A habitat is an area with a specific climate and ecosystem where animals and plants have what they need to survive. Each habitat has unique features that support the wildlife that live there. Creating a habitat inside a shoebox is a great way to illustrate the concept of a habitat to…
A moonquake is the moon equivalent of an earthquake. They tend to be less strong than earthquakes, but last longer. Apollo astronauts placed seismometers on the Moon between 1969 and 1972, which sent information about the quakes back to Earth. Moonquakes show that the Moon is still geologically active. Other types of quakes include Marsquakes,…
We’ve got some easy ( and tasty ) earthquake experiments to share today! Did you know the Earth is made up of large pieces of rock called tectonic plates? Where two tectonic plates meet is called a fault. If two plates rub together at a fault waves of energy ( seismic waves ) come to the surface…
Here at Science Sparks we love easy STEM challenges. Not only are they great fun but also a wonderful opportunity for children to work together creatively to solve a problem. Building and engineering projects are especially good for encouraging kids to think and re-evaluate if something doesn’t work. STEM Challenges tend to be simple to…
Water and oil do not mix. They are said to be immiscible. This is because water is a polar molecule – its structure means that is has a positive charge one end and a negative charge the other end. Water molecules stick together because the positive end of one water molecule is attracted to the…
Red cabbage indicator turns pink in the presence of acids, so by testing different types of acids ( lemon juice and vinegar are good to try ), you can make a range of lovely pink potions perfect for Valentine’s Day! If pink isn’t your thing, add an alkali ( baking soda works well ) and…
If you’ve ever made an erupting volcano model you most likely used the baking soda and vinegar reaction to make it erupt. Baking soda and vinegar react to neutralise each other ( vinegar is an acid and baking soda an alkali ) releasing carbon dioxide, which is the bubbles of gas you see. If you…
I’ve got lots of fun activities and facts about the Moon to share today. The Moon is probably more important to the Earth than you think. Did you know it stabilises the wobble of the Earth on its axis, giving us a fairly stable climate and causing tides? Moon Facts Did you know the Moon…
This heart model is a great demonstration of one chamber of the heart and valve. The heart has two features that keep blood flowing in the right direction. These are chambers and valves. Chambers fill with blood, then squeeze to pump the blood out. Each side of the heart has an entry chamber ( atrium…
