Science is an integral part of a school child’s curriculum. With environmental influences and factors becoming more prominent, it’s important that our students are educated about these effects, whilst also learning the fundamentals of biology, chemistry, and physics. Finding creative ways to teach science isn’t always easy, but we hope that our list of 30 exciting ideas will inspire you and your students both in and out of the classroom!
1. Finding the Speed of Light
This interesting physics experiment is a great homework activity or if you have access to microwaves in the classroom, it’s easy to conduct in class too. This requires students to measure the melting differences between a plate of marshmallows in the microwave to calculate the speed of light!

12. Making Cells
Provide your students with lots of junk modeling materials and a rubric (provided via the link) and get your students to construct their own cells and present them back to the class; therefore teaching each other the important concepts of this topic!

15. Strawberry DNA
DNA is a must-teach point for all high school students and this activity will give them the opportunity to extract it themselves from a strawberry! The reason for this is that strawberries contain a lot of DNA and there is a higher chance of a successful experiment!

16. DNA/RNA Comparison
It’s sometimes a little difficult for students to visualize what we talk about on a cellular level. Being able to build models is a great way to allow them to interact and envisage what they should look like. This simple lesson uses sweets and toothpicks as well as a handy printable to develop their understanding in no time.

17. Use Epsom Salts for Warmth
Epsom salts, when dissolved, create a wonderful endothermic reaction so not only with students see the reaction, but they will also be able to ‘feel’ it too! This can then lead to a good opportunity to teach about different types of reactions and energy changes.

18. Making Lungs
Smoking and tobacco abuse are major issues in many countries around the world. Highlight this in biology lessons by creating lungs from balloons-healthy and unhealthy- and students can see the effects in front of them.

19. Virtual Dissection Labs
We all have at least one student who is a little bit squeamish when it comes to specific experiments. With these clever ideas for virtual interactives, they can still learn the same concepts without having to dissect a real organism!

20. Magic Milk
This is a great idea for a Christmas-themed activity. In another reaction-based project, the proteins in the milk react with the detergent, and the food coloring then moves!
