How do scientists uncover the truth? They follow the scientific method: 
1️⃣ Make an observation
2️⃣ Ask a question
3️⃣ Generate a hypothesis
4️⃣ Conduct an experiment
5️⃣ Analyze data & draw conclusions

🔬 We get it: #LabRules can feel repetitive or even boring compared to the excitement of experiments. But the moment you step into a lab without supervision, you quickly realize why they matter. Even a “small” mistake, like misusing equipment, can lead to serious accidents.

If you were to sort a pine tree, a flower, a bear, a worm, and a mushroom into groups, how would you do it? Would you group them by their movement? By their size? Scientists use classification to organize organisms based on their traits to better understand relationships between organisms.

A split graphic illustrating a tree, mushroom, and flower labeled "Can't move" on the left, and a bear and worm labeled "Can move" on the right. A classification chart showing the hierarchy of animal taxonomy with emojis: Kingdom to Species, featuring dog, wolf, fox, lion, elephant, shark, and butterfly. Comparison of a phylogenetic tree and a cladogram, both showing evolutionary relationships of dog, wolf, fox, and lion. Illustration of an evolution chart showing mammals (dog, wolf, fox, lion, elephant) with traits: warm-blooded, have hair. The fish and butterfly don't share these traits.
