This summer, Dr. Sparks Jr. Scientist Club will take your kids on a full day journey back in time. We will explore the science behind ancient warfare and the evolution of weapons like crossbows and catapults. This full day, whole-English summer camp is available in communities around Taiwan. We also have the option to have our teachers come right to your community and perform the camp for your group of 15 kids in your building. Spend the day using English to build machines, collect data, test theories, conduct experiments, and have a whole lot of fun!

  In Dr. Sparks Science Camp – Ancient Warfare, we will look at the science behind some of the weapons that were able to take down great castles. We will explore how they used horsehair to create a weapon that could turn a tree into a missile. We will experiment with how they calculated trajectory to launch huge stones over city walls. And they did all of this without computers or even smartphones! Each child will spend the day using English while they make 2 amazing experiments that they can take home. This camp is not a day of learning English. Instead, it’s a day filled with fun experiments that encourage your kids to start using English and thinking in English. It’s through the curiosity that our experiments encourage that we help turn on your child’s English thinking.


  The boys and girls will do experiments with Dr. Sparks learning how science created ancient weapons that could bring down castle walls. Crossbows were a weapon that used tension and elasticity to fire a weapon straight ahead from far away. Catapults used similar ideas but changed the design so that larger items could be shot at a higher trajectory.

  We will use English to learn the science behind these war machines in a safe environment. Dr. Sparks understands that not all kids will understand everything that they hear. That’s OK. What your children don’t understand with their ears, they will understand with their eyes and their hands. We create hands-on experiments that spark your children’s curiosity. When they are interested and curious about the experiment that we are doing, they will really open their minds to understand as much as they can.

  We want to create an environment where your kids can come and use their English minds while performing awesome experiments. We feel that most kids don’t need to just go and learn more English. What most kids really need is an English environment that is really interesting, low pressure, and free of writing homework and tests. Why not make English an experience instead of a class? Dr. Sparks Jr. Scientist Club – English, Science, Fun!
