We’ve dissected flowers many times before, but this was our first attempt at a 3D flower model. A model is a great hands-on way to learn about the structure and function of plant organs and the importance of pollination. I’ve also made some FREE flower structure revision cards you might like. 3D Flowering Plant Model…
One of our most popular posts is this great collection of Fairy Tale science activities, so when the lovely Mrs Mactivity asked if we’d like her to create some resources to sit alongside our Fairy Tale STEM challenges, we said YES! These Fairy Tale STEM activities are great for elementary or primary school-age children and…
Refraction is the bending of light. Light bends whenever it travels from one transparent material to another. One example of this is light travelling through a glass. The reason light bends when it passes between two materials is because it changes speed. If the new material is more dense ( for example air to glass…
We’ve done this light refraction experiment many times before, but this time it’s Alice in Wonderland themed. A reversing arrows science investigation is very easy and can be made as simple or creative as you wish. If you don’t want to theme it like I have below, just draw arrows on a small piece of…
I’ve got another easy EGG themed STEM Challenge for you today! It’s a bit of a twist on the traditional egg drop experiment. The challenge is to build a car using K’Nex or another construction toy to save an egg passenger. This is a brilliant egg experiment, that’s great for any time of year, but especially Easter!…
This fun tooth decay experiment with egg shells is all about teeth and how to keep them healthy. First, we discussed the importance of brushing teeth every day, and then we chatted about foods that are good for your teeth and those that aren’t. Sugary, sticky foods are not good for teeth as they stick…
One of the easiest ( and tastiest ) ways to introduce science at home is in the kitchen. If you’re a regular reader, you’ve probably already seen my huge kitchen science experiment round-up post, full of simple, tasty, and educational ideas for science in the kitchen. Pancakes are a great way to learn about how…
Fresh eggs sink, and older eggs float. Eggs have air cell that becomes bigger as they age. Once the air pocket is big enough to make the egg less dense than water, the egg floats!! Another way to make an egg float is to increase the density of the water the egg is in! Once…
Eggs with no shells are definitely one of the things my children find most intriguing. I’ve made bouncy eggs for nursery children to look at and for secondary school children to use as part of an osmosis experiment. This fun bouncy egg experiment is great fun for kids of all ages and fascinating for adults…
This egg experiment shows that something we might think of as brittle and weak can actually support a heavy load under certain conditions. We’re going to investigate how strong an eggshell is by using half-shells to make a bridge. How strong is an eggshell? You’ll need How to make an eggshell bridge Method 1 Method 2…
