Our age 8-9 homeschooled children have been investigating the causes of earthquakes during their recent science sessions.
Some of the most spectacular features on our planet from the Himalaya Mountains to the Pacific and Atlantic oceans have been created in association with earthquakes.
Earthquakes are caused by motions in the Earth’s plates. While earthquakes can be destructive, they are also an expression of the dynamic forces within Earth that shape the planet on which we live.
The children were given a hands-on activity to complete at home.
This involved investigating the effect of glacial movement on landforms.
The children used sandy ice cubes as a model of a glacier which had pieces of rock in its ice.
Once they completed the activity, they recorded the results and gave a description of what they discovered.
Our KS3 Chemistry students have been taking a closer look at Acids and Alkalis by investigating and exploring the pH scale using red cabbage indicator.
Using the home learning pack, the students were able to use a red cabbage indicator strip to test the pH values of various substances, such as lemonade, bleach, washing powder, and others.
The children explored neutralisation reactions by using red cabbage indicator to test the pH of vinegar and bicarbonate of soda before and after they react.
The indicators helped tell whether the substance was acid, alkaline, or neutral. Students got to see the indicators turn a range of colours, depending on the pH of the substance then discussed the results.
Class 9-10 have been on a digestion journey this week during their science lesson! Over the past several weeks, the students have learned about the human digestion process from saliva breaking down your food to it passing through the stomach to the small and large intestines. For this weeks science experiment, the children were able to see the process of what stomach acid does to food. During digestion, food passes through the stomach, where it mixes digestive juices and is churned by muscles forming the stomach wall. The students provided the muscles and the soft drink for the stomach acid. The children placed a soft drink, bread and chewed gum in a food storage bag. They squeezed the bag with their hands for about a minute. The children were able to record thier observations and wrote down what they discovered. What happened to the bread? what happened to the gum? By the end of the session, the children were able to write up and explain why the gum and bread reacted in the way that it did using the correct scientific vocabulary in their workbooks!
Class 8-9 have been learning all about different types of seeds and seed dispersal, Our students have discovered different types of seeds found in all types fruit. They were able to identify the different shapes, sizes and colours of seeds from different fruits. Some plants make tasty fruits. This is to encourage animals (and people!) to eat the fruits. The seeds then pass through the animal unharmed and out the other end with a ready supply of fertiliser (not tasty in the slightest…quite the opposite!). This method ensures the seed is given nutrients to help it grow.
- Plant seeds can be dispersed in a number of different ways. Some seeds are transported by wind, and have seeds designed to float, glide or spin through the air
- Many plants also use animals to carry seeds around. These seeds may have handy hooks which attach to an animal’s fur.
Our mini scientists ages 9-10, have been finding out what really happens when you swallow gum?. During their science investigation, children have been learning about the human digestive system. They can confidently label parts of the digestive system using vocabulary such as; Stomach, esophagus, large intestine, salivary glands and small intestine. Children shouldn’t chew gum until they fully understand the importance of not swallowing it. By age 5, most children will understand that gum is different than sweets and is not to be swallowed. Chewing gum is made of either natural or synthetic materials (gum resin), preservatives, flavorings, and sweeteners. The body can absorb sweeteners, such as sugar But the human digestive tract can’t digest the gum resin. It’s moved through the digestive tract by the normal pushing (peristaltic) actions of the gut. The gum’s journey ends during a trip to the bathroom!
📚Our Tuition Club Online Science students have been learning about Chromatography- Separating dissolved Solids.
The Students looked at paper chromatography which is a method for separating dissolved substances from one another. The activity was based on how to separate mixtures (inks) and results were shared.
Alternative energy sources are a big deal these days. One such source is the wind. Our Homeschooled children having been finding out how wind turbine can use the power of the wind to generate energy for their science project. The students aged 10-11, designed various turbines using diffrent blades to find out which produces the most energy, and put the wind to work!
Our homeschooled children have been experimenting! The students aged 10-11 used electricity to split water into its two elements, hydrogen and oxygen. Although the oxygen remain dissolved, they saw evidence of the hydrogen ions. This process is called Water Electrolysis.
Our home-schooled girls aged 13-14 have been ‘Raising- Standards’ in their science experiments! The group enjoyed a fun session at the Tuiton club making Pancakes. Ever wondered what does science have to do with pancakes?.. well, when you make pancake batter you are mixing a whole range of different chemicals – so all sorts of reactions take place in the cooking! The dry ingredients contain flour and sugar, as well as salt and maybe either baking powder or baking soda. Flour supplies protein, molecules made of lots of amino-acids joined in chains, along with starch, which similarly is made of lots of simple sugar molecules joined in chains.
Our home schooled children in year 3 and 4 have been learning all about fossilization during their science lesson. The children have learnt that fossils are the preserved remains or traces of living things from the past. There are many ways to form fossils. The experiment conducted by the children modelled the casting and moulding method. The dent made by the object, in this case were mini- dinosaur figurines in the clay is the mould. It shows the detail of the object’s surface. Groundwater leaks in to the moulds and then evaporates, leaving minerals behind. The minerals dry up and harden and this creates a cast. The children went on to pour pva glue into the moulds and baked in the oven to harden up to reveal their very own fossils!
